刪除HTML元素可以使用remove及empty,下面有關這兩個方法的使用我在這里將以實例的方式來給大家講解。
remove() – 刪除指定的元素(包括其子元素)
empty() – 清空指定元素的子元素
列如:
<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>Remove div element</button>
</body>
</html>
empty:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JQuery Demo</title>
<script src="scripts/jquery-1.9.1.js"></script>
<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()方法也支持一個參數,可以用于過濾一些需要刪除的HTML元素。這個參數可以為任何有效的jQuery selector.
比如下面代碼只刪除class=”italic”的<p>元素:
