[英]How to get id of div or anchor tag ,when clicked , with pure javascript
[英]How to get the attribute value of “id” from the anchor tag by class name when its clicked?
$("#jqxTree-ReportGroups ul").append("<li id=" + [data[i].Id] + " item-checked='true' item-expanded='true' class='treeLi'>
<a class='report-tree-expand' href=''>+</a>
<a class='reportData' id='12345' href=''>" + [data[i].Name] + "</a></li>");
单击时如何通过类名“reportData”获取“id”的属性值?
编辑:点击不工作..如果我使用Live,该函数被调用...怎么做在实时函数内获取reportData的Id
看看这个代码:
$(document).on('click' , '.reportData' , function(){
var idProp= $(this).prop('id'); // or attr()
var idAttr = $(this).attr('id');
console.log('using prop = ' + idProp + ' , using attr = ' + idAttr);
console.log();
return false; // to prevent the default action of the link also prevents bubbling
});
完成使用它已被弃用(需要jquery版本1.7及以上)但这里是使用live()的代码
$('.reportData').live('click' , function(){
var idProp= $(this).prop('id'); // or attr()
var idAttr = $(this).attr('id');
console.log('using prop = ' + idProp + ' , using attr = ' + idAttr);
console.log();
return false; // to prevent the default action of the link also prevents bubbling
});
jsfiddle证明工作
你可以做
$(document).on("click", ".reportDatan", function() {
var id = this.id;
});
使用事件委派,因为它看起来像是动态添加它。
尝试这个:
$('.reportDatan').click(function(){
$(this).attr('id');
});
如果您使用的是jquery 1.9
$('.reportDatan').click(function(){
$(this).prop('id');
});
你在jQuery中连接HTML字符串是错误的,看看这个具有实时功能的代码,或者如果你想让它可读,你也可以使用JavaScript Template Engine Mustache
HTML:
<div id="jqxTree-ReportGroups">
<ul>
<li>First</li>
</ul>
</div>
jQuery的:
$(document).ready(function () {
var yourLiID = 100;
var aValue = 'Report Data';
var yourLi = "<li id='" + yourLiID + "' item-checked='true' item-expanded='true' class='treeLi'>";
var yourAnchor = "<a class='report-tree-expand' href=''>Your Text</a> ";
var secondAnchor = "<a class='reportData' id='12345' href=''>" + aValue + "</a>";
var yourLiClose = '</li>';
$("#jqxTree-ReportGroups ul").append(yourLi + yourAnchor + secondAnchor + yourLiClose);
$('.reportData').live("click", function(){
var yourAnchorID = $(this).attr('id');
alert('yourAnchorID: ' + yourAnchorID);
return false;
});
});
