如何使用jQuery删除由onclick生成的多个div元素

Question

我可以使用单击添加div内容，并且可以生成多个或更多内容，但是我还想在用户单击“删除”按钮时删除该生成的div。 我已经尝试了一些，但只删除了一次。 如果我生成了一个单击，则在单击删除时将其删除，但是当我生成两个或更多时，它将不起作用。

 $(document).ready(function() { $("button[name='addDom']").click(function() { var domElement = $('<div class="row " id="removechild"><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button onclick="clearBox()" class="btn btn-danger">Remove Child</button><hr>'); $(this).after(domElement); }); }); function clearBox(removechild) { document.getElementById('removechild').innerHTML = ""; } $("#removechild").html("");

• 用一个班级（孩子）将整个“部分”包装在div中。
• 从div中删除了ID“ removeChild”，因为该ID不应超过1个。
• 删除了内联的onclick事件，并替换为一个事件，该事件将删除最靠近您单击的按钮的部分。
• 在移除按钮上添加了一个类（removeChild），因此我们可以使用该类轻松设置click事件。

 $(document).ready(function() { $("button[name='addDom']").click(function() { var domElement = $('<div class="child"><div class="row "><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button class="removeChild" class="btn btn-danger">Remove Child</button><hr></div>'); $(this).after(domElement); }); $(document).on('click','button.removeChild',function(){ $(this).closest('div.child').remove(); }); });

Answer 2

在您的addDom中，单击添加此代码

   var domElement = $('<div class="child"><div class="row "><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button class="removeChild" class="btn btn-danger">Remove Child</button><hr></div>');
$(this).after(domElement);

然后在外面贴上

$(document).on('click','button.removeChild',function(){
     $(this).closest('div.child').hide();
 });

会工作的！

Answer 3

尝试这个：

$('addBtn').click(function(){
    var $div = $('<div class="test">...</div>');
    $(this).after($div);
})

$('.removeBtn').click(function(){
    var $div = $('.test').last();
    $div.length && $div.remove();
})

Answer 4

您应该将表单包装成div，然后像这样删除div：

 var id = 0; $(document).ready(function() { $("button[name='addDom']").click(function() { var domElement = $('<div class="rowItem"><div class="row" id="removechild"><hr><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">First Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="first_name" placeholder="First Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Last Name</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="last_name" placeholder="Last Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Gender</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"> <option value="">Male</option><option value="">Female</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Date of Birth</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input type="date" class="form-control" id="exampleInputDOB1" placeholder="Date of Birth" required="required" style="width:124%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Class Coordinator (if applicable)</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="class_coordinator" placeholder="Class Coordinator Name" class="form-control" type="text" required="required" style="width:200%"></div></div></div></div><div class="col-md-6 col-lg-6"><div class="form-group"><label class="col-md-4 control-label">School Currently Attending</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="school" placeholder="School Currently Attending" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Relation with child</label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span> <input name="relation" placeholder="Relation with child" class="form-control" type="text" required="required" style="width:200%"></div></div></div><div class="form-group"><label class="col-md-4 control-label">Types of soccercric</label><div class="col-md-4 selectContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-list"></i></span><select name="gender" class="form-control selectpicker"><option value="">Soccer</option><option value="">Cricket</option></select></div></div></div><div class="form-group"><label class="col-md-4 control-label">Child medical condition <br> <span style="font-size:10px">Please indicate any relevant medical conditions or allergies your child may have (not required if your child has no relevant medical issues)</span></label><div class="col-md-4 inputGroupContainer"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span><input name="relation" placeholder="Child medical condition" class="form-control" type="text" required="required" style="width:200%"></div></div></div</div</div><br><br><br><button onclick="clearBox(this)" class="btn btn-danger">Remove Child</button><hr></div>'); $(this).after(domElement); }); }); function clearBox(removeChild) { $(removeChild).parentsUntil('.rowItem').html(''); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button name="addDom" class="btn btn-warning"> Add Child</button> 

我正在使用jQuery的ParentsUntil来获取包装div并删除div中的所有项目。

Answer 5

您需要分配一个唯一的ID，然后在clearBox函数中提供此唯一的ID。

$(document).ready(function() {
    var count = 0;

    $("button[name='addDom']").click(function() {
        var uniqueID = "removechild-" + count,
            html = '<div class="row" id="' + uniqueID + '">row of stuff<button onclick="clearBox(\'' + uniqueID + '\')" class="btn btn-danger">Remove Child</button></div>';

        $(this).after(html);

        count++;
    });
});

function clearBox(idToRemove) {
    document.getElementById(idToRemove).innerHTML = "";
}

Answer 6

正如我自己和@guradio在评论中提到的那样，您的ID应该是唯一的。 最简单的方法是使全局整数变量附加到每个元素ID上，然后递增：

var elemIndex = 0;
createElement(){
    var newId = "someElement" + elemIndex;
    var domElement = '<div id="'+ newId +'"'>...</div>';
}

单击删除按钮，然后应调用clearBox方法，并填充唯一ID（看起来您的方法已开始使用参数支持此方法）：

clearBox(elementId){
    document.getElementById(elementId).innerHtml = "";
}

和按钮（在构建元素字符串时将出现）：

var domElement = '...<button type="button" onclick="clearBox('+ newId +')">Clear</button>...';

Answer 7

您可以使用Jquery Traversing实现此目的。 单击删除按钮可以删除对应的父div。 请参阅此Jsfiddle链接。

$(document).on( "click", ".removeBtn", function() {
  $(this).parent().parent().parent().remove();
});
