Two implementation methods: 1. Use ":hidden" and the syntax "$(":hidden")" to directly select hidden elements; 2. ":visible" and ":not()" Used in conjunction with the syntax "$(":not(:visible)")", you can select elements outside of the displayed state, that is, select hidden elements.
The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.
jquery can use the following two methods to find hidden elements:
Use directly :hidden selector
Use: visible and :not() selectors
1. Use the :hidden selector
: The function of the :hidden selector is to select hidden elements .
Example: Show hidden elements
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$(":hidden").show(3500);
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<p>这是另外一个段落。</p>
<p style="display:none;">这是一个隐藏段落。</p>
<div style="display:none;">这是隐藏的 div 元素。</div>
</body>
</html>
2. Use :visible and :not() selectors
: The visible selector selects each element that is currently visible.
: The not() selector selects all elements except the specified element.
":visible" and ":not()" are used together to select elements outside the display state, which is to select hidden elements.
Example: Show hidden elements
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$(":not(:visible)").fadeToggle(3500);
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<p>这是另外一个段落。</p>
<p style="display:none;">这是一个隐藏段落。</p>
<div style="display:none;">这是隐藏的 div 元素。</div>
</body>
</html>
