<body>
<div id=

<p>This is another paragraph

</div>
<br>

<!DOCTYPE html>

<script>
$(document).ready(
function
() {
$(
"button"
).click(
function
() {
$(
"#div1"
).empty();
});
});
</script>
</head>
<body>
<div id=
"div1"
style=
"height: 100px; width: 300px;
border: 1px solid black; background-color: yellow;"
>
This is some text
in
the div.
<p>This is a paragraph
in
the div.</p>
<p>This is another paragraph
in
the div.</p>
</div>
<br>
<button>Empty the div element</button>
</body>
</html>
jQuery的remove()方法也支持一个参数,可以用于过滤一些需要删除的HTML元素。这个参数可以为任何有效的jQuery selector.
比如下面代码只删除class=”italic”的<p>元素:
$( "p" ).remove( ".italic" ); |
