Javascript动态脚本加载IE问题 [英] Javascript Dynamic Script Loading IE problems
问题描述
我正在尝试使用以下代码动态加载脚本:
I'm trying to load dynamically script with this code:
var headID = document.getElementsByTagName("head")[0];
var script = document.createElement('script');
script.type='text/javascript';
script.src="js/ordini/ImmOrd.js";
script.setAttribute("onload", "crtGridRicProd();");
headID.appendChild(script);
页面启动时，我需要启动crtGridRicPrdo()函数，并且在FireFox中一切正常，但是在Internet Explorer中，我遇到了问题！
I need to launch crtGridRicPrdo() function when the page starts, and in FireFox all works fine but in Internet Explorer I have a problems!
推荐答案
Internet Explorer不支持脚本标签上的"onload"，而是提供了"onreadystatechange"(类似于xhr对象).您可以通过以下方式检查其状态:
Internet explorer does not support "onload" on script tags, instead it offers the "onreadystatechange" (similarly to an xhr object). You can check its state in this way:
script.onreadystatechange = function () {
if (this.readyState == 'complete' || this.readyState == 'loaded') {
crtGridRicProd();
}
};
否则，您可以在js文件末尾调用 crtGridRicProd()
otherwise you can call crtGridRicProd() at the end of your js file

示例:
test.js:
function test() {
alert("hello world");
};
index.html:
index.html:
<!DOCTYPE html>
<html>
<head>
<title>test</title>
</head>
<body>
<script>
var head = document.getElementsByTagName("head")[0] || document.body;
var script = document.createElement("script");
script.src = "test.js";
script.onreadystatechange = function () {
if (this.readyState == 'complete' || this.readyState == 'loaded') {
test();
}
};
script.onload = function() {
test();
};
head.appendChild(script);
</script>
</body>
您将在两个浏览器中看到警报！
you will see the alert in both browser!
