在HTML中包含js文件(Inclusion of a js file in HTML)

在HTML中包含js文件(Inclusion of a js file in HTML)

我在我的HTML中包含一个巨大的javascript文件（500K）。 有没有一种聪明的方法来知道它是否已被加载。 我能想到的一种方法是在其构造函数中有一个变量来初始化并通知我。 加载是异步的，我不能继续，直到包含该JS的函数。

谢谢

I am include a huge javascript file(500K) in my HTML. Is there a smart way to know if it has been loaded. One way I can think of is to have a variable in its constructor to initialize and inform me . The loading is asynchronous and I cannot proceed until function s of that JS are included.

Thanks

通过使用jQuery，您可以处理在加载脚本文件时运行的回调函数：

$.getScript("yourScriptFile.js", function(){ // What to do when the script is loaded });

文件

By using jQuery you can handle a callback function that runs when the script file is loaded:

$.getScript("yourScriptFile.js", function(){ // What to do when the script is loaded });
