jQuery Tips: How to quickly obtain the screen height

In web development, we often encounter situations where we need to obtain the screen height, such as implementing responsive layout, Dynamically calculate element sizes, etc. Using jQuery, you can easily achieve the function of obtaining the screen height. Next, we will introduce some implementation methods of using jQuery to quickly obtain the screen height, and attach specific code examples.

Method 1: Use jQuery’s height() method to obtain the height of the screen

You can easily obtain the height of the screen by using jQuery’s height() method. The example is as follows:

$(document).ready(function(){
    var screenHeight = $(window).height();
    console.log("屏幕高度为：" + screenHeight + "px");
});

In the above code, the height of the screen can be obtained through $(window).height() and output to the console.

Method 2: Combining the resize event to dynamically obtain the screen height

Sometimes it is necessary to obtain the screen height in real time, such as when the browser window size changes. At this time, you can combine the resize event to dynamically obtain the screen height. The example is as follows:

$(window).resize(function(){
    var screenHeight = $(window).height();
    console.log("屏幕高度变化为：" + screenHeight + "px");
});

In the above code, by binding the resize event, when the browser window size changes, the height of the screen will be dynamically obtained and output to in the console.

Method 3: Use the innerHeight property to get the screen height

In addition to using the height() method, you can also use jQuery’s innerHeight property to get the screen height. The example is as follows:

$(document).ready(function(){
    var screenHeight = $(window).innerHeight();
    console.log("屏幕高度为：" + screenHeight + "px");
});

## The #innerHeight property has the same function as the height() method and can be used to obtain the screen height.

Method 4: Use the outerHeight(true) attribute to get the screen height

Finally, you can also use the outerHeight(true) attribute to get the screen height. The example is as follows:

$(document).ready(function(){
    var screenHeight = $(window).outerHeight(true);
    console.log("屏幕高度为：" + screenHeight + "px");
});

outerHeight( true) attribute can include the element's borders, padding and scroll bars, and is a more comprehensive method of obtaining the screen height.

In summary, the above are several ways to quickly obtain the screen height using jQuery, with specific code examples attached. In actual development, choosing the appropriate method to obtain the screen height according to needs can better achieve web page layout and interactive effects.
