[英]delete div on button click
我试图删除div
按钮单击,但问题是我需要按钮删除它包含的div而不将div的id传递给删除按钮
所以最后这段代码应该能够删除div而不传递div的id,而是依赖于传递this
引用
<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
$(document).on('mouseenter', '#divbutton', function() {
$(this).find(":button").show();
}).on('mouseleave', '#divbutton', function() {
$(this).find(":button").hide();
});
});
</script>
<style>
#divbutton {
height: 100px;
background: #0000ff;
}
#divbutton2 {
height: 100px;
background: #0000ff;
}
#divbutton3 {
height: 100px;
background: #0000ff;
}
</style>
</head>
<body>
<div id="divbutton">
<button type="button" style="display: none;" id="i" onclick="document.body.removeChild(document.getElementById('divbutton'))">Hello</button>
</div>
<div id="divbutton2">
<button type="button" style="display: none;" id="i" onclick="document.body.removeChild(document.getElementById('divbutton2'))">Hello </button>
</div>
<div id="divbutton3">
<button type="button" style="display: none;" id="i" onclick="document.body.removeChild(document.getElementById('divbutton3'))">Hello </button>
</div>
</body>
</html>
如果你想知道如何使用this
引用来获取父元素以将它传递给removeChild
,那么它很容易,只需使用parentNode
:
<div class="divbutton">
<button type="button" style="display: none;" id="i" onclick="document.body.removeChild(this.parentNode)">Hello</button>
</div>
但是,既然你正在使用jQuery,那么利用它的功能是有意义的:
$(document).on('mouseenter', '.divbutton', function () {
$(this).find(":button").show();
}).on('mouseleave', '.divbutton', function () {
$(this).find(":button").hide();
}).on('click', ':button', function() {
$(this).parent().remove();
});
我还将id #divbuttonX
更改为类名.divbutton
,在这种情况下CSS变得更简单。

您可以使用.closest删除div
$(document).ready(function () { $(document).on('mouseenter', 'div[id^=divbutton]', function () { $(this).find(":button").show(); }).on('mouseleave', 'div[id^=divbutton]', function () { $(this).find(":button").hide(); }); $(document).on('click', 'button#i', function () { $(this).closest("div").remove(); }); });
#divbutton { height: 100px; background: #0000ff; } #divbutton2 { height: 100px; background: #0000ff; } #divbutton3 { height: 100px; background: #0000ff; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="divbutton"> <button type="button" style="display: none;" id="i" >Hello</button> </div> <div id="divbutton2" > <button type="button" style="display: none;" id="i">Hello </button> </div> <div id="divbutton3" > <button type="button" style="display: none;" id="i">Hello </button> </div>
试试这会有所帮助:
。$(本).parent()最接近( 'DIV')隐藏();
$("button").click(function () {
$(this).parent().closest('div').hide();
});
演示:
$("button").click(function () { $(this).parent().closest('div').hide(); });
#divbutton { background:powderblue; padding:10px; height:100px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <div id="divbutton"> <button id="i">Hello</button> </div>
