onload()后加载外部JavaScript文件 [英] Load external javascript file after onload()
本文介绍了onload()后加载外部JavaScript文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在头
标记中使用它:
< script src =js / lightbox.js>< / script>
是否可以从标题中删除它,并使用 onload加载此文件()
?
< body onload =...> ...< ; /体>
注意:这不是一个函数,它是一个包含多个函数的外部js文件。
$ b
谢谢!
解决方案
< script> ;
函数loadJS(src,callback){
var s = document.createElement('script');
s.src = src;
s.async = true;
s.onreadystatechange = s.onload = function(){
var state = s.readyState;
if(!callback.done&&(!state || /loadedcombilled/.test(state))){
callback.done = true;
callback();
}
};
document.getElementsByTagName('head')[0] .appendChild(s);
}
loadJS('/ script / script.js',function(){
//将脚本加载后运行你的代码
});
< / script>
我仍然认为在jQuery中加载并使用$ .getScript会更好,因为您有很多好东西在那里。
可以在身体负荷上调用此功能
I use this in the head
tag:
<script src="js/lightbox.js"></script>
Is it possible to remove this off the header and load this file with onload()
?
<body onload="...">...</body>
Note: This is not a function, it's an external js file with several functions.
Thanks!
解决方案
<script>
function loadJS(src, callback) {
var s = document.createElement('script');
s.src = src;
s.async = true;
s.onreadystatechange = s.onload = function() {
var state = s.readyState;
if (!callback.done && (!state || /loaded|complete/.test(state))) {
callback.done = true;
callback();
}
};
document.getElementsByTagName('head')[0].appendChild(s);
}
loadJS('/script/script.js', function() {
// put your code here to run after script is loaded
});
</script>
I still think its better to load in jQuery and use $.getScript instead as you have lots of goodies there.
Can call this on body load
