Sharing several ways to use jQuery to get the screen height

In front-end development, getting the height of the browser window is a common task. This is important in many aspects of web design and interaction. When implementing this function, jQuery is a commonly used tool, which allows us to manipulate DOM elements more conveniently. In this article, we will share several ways to use jQuery to obtain the screen height and provide specific code examples.

1. Use $(window).height()Method:
   This is the simplest and most common way, use $(window). The height() method can directly obtain the height of the browser window. The following is a simple sample code:

$(document).ready(function() {
    var windowHeight = $(window).height();
    console.log("窗口高度为：" + windowHeight);
});

2. Use the $(document).height() method:
   In addition to getting the window height, sometimes we also Need to get the height of the entire document. At this time, you can use the $(document).height() method. The following is a sample code:

    var elementHeight = $("#element").height();
    console.log("元素高度为：" + elementHeight);
});

4. Use the $(window).scrollTop() method to obtain the height of the element Page scroll height:
   When the page scrolls, we may want to get the scrolling distance. At this time, you can calculate it by combining the $(window).scrollTop() method and the window height. The following is a sample code:

    var scrollHeight = $(window).scrollTop();
    var windowHeight = $(window).height();
    console.log("页面滚动高度为：" + scrollHeight);
});
