jQuery is one of the most popular JavaScript libraries. It contains a wealth of functions and methods that can easily complete various website effects. In jQuery, many convenient functions are provided, including hidden functions. Next, the usage and implementation of jQuery hidden functions will be introduced in detail.
1. What is jQuery hidden function?
The hidden function is a method provided by jQuery to operate elements, which can hide specified elements, that is, prevent them from being displayed on the page. By using the Hide function, you can easily hide a single element, a group of elements, or even all elements in an entire page.
2. Usage of jQuery hidden function
- Hide a single element
To hide a single element, you need to first select the element to be hidden through the selector. Then use the hide() function to hide it. For example:
$(".element").hide();In the above code, the element with the class name "element" is selected and the hide() function is called to hide it.
- Hide multiple elements
If you need to hide multiple elements at the same time, you can use the same selector to select multiple elements. For example:
$("p, .element, #id").hide();In the above code, all p tags, elements with class name "element" and elements with id "id" are selected, and the hide() function is called to hide them all.
- Hide all elements
If you need to hide all elements in the entire page, you can use the wildcard selector to select all elements. For example:
$("*").hide();In the above code, a wildcard selector is used to select all elements in the entire page, and the hide() function is called to hide them all.
3. Implementation of jQuery hidden functions
In actual development, the implementation of jQuery hidden functions is not complicated. You only need to introduce the jQuery library and call the corresponding functions. The following is a simple example that demonstrates how to use the jQuery hide function to hide an element:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery隐藏函数</title>
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<p>这是一个段落。</p>
<button id="hide-element">隐藏元素</button>
<script>
$(document).ready(function() {
$("#hide-element").click(function() {
$("p").hide();
});
});
</script>
</body>
</html>In the above code, the jQuery library is introduced and a paragraph and a button are added to the page. When the button is clicked, use the hide() function to hide the paragraph. It should be noted that the jQuery code must be executed after the page is loaded, otherwise the corresponding element cannot be found.
4. Summary
