<脚本>里面的javascript代码document.write（） [英] <script> inside javascript code document.write()
问题描述
我得到了嵌入HTML（在服务器端生成）的一部分javascript代码，如下所示：
I got a portion of javascript code embedded in HTML (generated on the server side) that looks like this:
function winWriteMail2(){
var win = open('','wininfo', 'width=400,height=300,scrollbars=yes,resizable=yes');
win.document.open();
win.document.write('<HTML><HEAD><META http-equiv="Content-type" content="text/html; charset=iso-8859-2"><LINK rel="stylesheet" type="text/css" href="/css/main.css">');
win.document.write('<scr' + 'ipt language="javascript" type="text/javascript" src="/js/JSFILE.js"></scr' + 'ipt>');
win.document.write('</HEAD><BODY BGCOLOR="#f7f3e7">');
<!-- window content goes here -->
win.document.write('</BODY></HTML>');
win.document.close();
}
此代码在点击元素时执行。
This code gets executed on click of a element.
对我来说有问题的部分是包含javascript文件 - 它在Firefox和Chrome中运行正常，但IE（7和8，正如我测试的）表现得很奇怪。在那里包含 JSFILE 的行，点击窗口打开，但是为空，CPU 100％忙，唯一的办法是杀死IE。
The problematic part for me is the inclusion of javascript file - it works ok in Firefox and Chrome, but IE (7 and 8, as I tested) behaves strange. With the line containing JSFILE there, the window on click gets opened, but is empty, CPU is 100% busy and only way is to kill IE.
任何人都可以帮忙解决这个问题吗？也许我应该用其他方式在那里插入javascript文件？
Anyone can help with handling this problem? Maybe I should use some other way to insert the javascript files in there?
我试过，而不是 win.document.write（），DOM操作方法，把这个部分 win.document.close（）之后的代码：
I tried, instead of win.document.write(), the DOM-manipulation method, putting this part of code after win.document.close():
h = win.document.getElementsByName('head')[0];
js = document.createElement('script');
js.src = '/js/JSFILE.js';
h.appendChild(js);
然后代码未加载，即使在Firefox中也是如此（并且使用firebug进行检查时未显示它甚至可以看到它）。
but then the code isn't loaded, even in Firefox (and inspecting with firebug doesn't show it even can see it).
经过一些检查后，我发现问题是由< script> <引起的/ code>定义了 src = 属性的元素。如果我添加内联脚本，例如：
After some checks, I found out that the problem is caused by <script> elements with a src= attribute defined. If I add an inline script, like:
<script type='text/javascript'>alert('foo')</script>
，窗口打开，警报框出现，一切都很好。
within my document.write(), the window opens, the alert box shows up and everything's all right.
但是使用
<script type='text/javascript' src='/js/foo.js'></script>
IE在打开新窗口时停止，继续使用100％的CPU。
IE stalls when opening the new window, keeps using 100% of CPU.
推荐答案
这段代码对我有用：
function winWriteMail2(){
var win = open('','wininfo', 'width=400,height=300,scrollbars=yes,resizable=yes');
win.document.open();
win.document.write('<HTML><HEAD><META http-equiv="Content-type" content="text/html; charset=iso-8859-2"><LINK rel="stylesheet" type="text/css" href="/css/main.css">');
win.document.write('</HEAD><BODY BGCOLOR="#f7f3e7">');
win.document.write('this is the body content');
win.document.write('</BODY></HTML>');
win.document.close();
var h = win.document.getElementsByTagName("head")[0];
var js = win.document.createElement("script");
js.type = "text/javascript";
js.src = "js/scriptfile.js";
h.appendChild(js);
}
以下是我需要更改代码才能使其正常工作：
Here is what I needed to change in your code to make it work:
//From
var js = document.createElement("script");
//To
var js = win.document.createElement("script");
您需要在要附加的同一文档中创建脚本元素。
You need to create the script element in the same document that you are appending.
