将表单发布到IFrame的问题 [英] Problem posting form to an IFrame
问题描述
我有一个使用Ajax的相当复杂的业务应用程序。部分
此表格的
需要上传文件，我无法使用
Ajax，所以我将表格发布到IFrame。这部分工作正常。
我遇到的问题是我的服务器进程将一些内容返回到IF $以完成表单处理并报告任何错误
可能已经发生了。这里有一个可以回写的例子：
< html>
< head>
< ; script type =" text / javascript">
函数已完成（）{
window.parent.reportsCompleted（）;
}
< / script>
< body onload =" completed（）;">
< error>该文件类型.doc不受支持。< / error>
< / body>
< / html>
现在这可以正确调用父
帧的reportsCompleted方法。我遇到的问题是读取任何< error>
标记的内容（如果存在）：
函数reportsCompleted（）{
var frame = frames [''upload_frame''];
if（frame.document.getElementsByTagName（" error"）。leng th 0）{//
有错误...
var message ="发生以下错误：" ;;
for（var i = 0; i<
frame.document.getElementsByTagName（" error"）。lengt h; i ++）{
message + =" \ n" +
frame.document.getElementsByTagName（" error"）[i] .nodeValue（）;
}
alert（message）;
}
}
问题是我从来没有得到错误标签的内容
显示。我只看到一个警告窗口，上面写着发生以下
错误：。
我做错了什么？
I have a rather complicated business application that uses Ajax. Part
of this form requires uploading documents, which I cannot do using
Ajax, so I post the form to an IFrame. This part works just fine.
The problem I have is that my server process returns some content to
the IFrame to complete form processing and to report any errors that
might have occured. Here''s an example of what may be written back:
<html>
<head>
<script type="text/javascript">
function completed() {
window.parent.reportsCompleted();
}
</script>
<body onload="completed();">
<error>The document type .doc is not supported.</error>
</body>
</html>
Now this does properly call the reportsCompleted method of the parent
frame. The problem I am having is reading the contents of any <error>
tags if they exist:
function reportsCompleted() {
var frame = frames[''upload_frame''];
if (frame.document.getElementsByTagName("error").leng th 0) { //
there were errors...
var message = "The following error(s) occured:";
for (var i = 0; i <
frame.document.getElementsByTagName("error").lengt h; i++) {
message += "\n" +
frame.document.getElementsByTagName("error")[i].nodeValue();
}
alert(message);
}
}
The problem is that I never get the contents of the error tags
displayed. I only see an alert window that says "The following
error(s) occured:".
What am I doing wrong?

为什么不使用.innerHTML而不是你不存在的.nodeValue（）？

请改用：

var c = frame.document.getElementsByTagNa我（错误）;
var len = c.length;
if（len 0）

Use instead:
if (frame)

使用非 - 应该是HTML文档中的-HTML元素，

< erroris不是标准的HTML元素，然后不同的浏览器在unknow标签上有不同的行为
不同的行为
对于IE，你应该为自定义元素定义命名空间
（xmlns：my =" http：//xxxx...."然后使用我的：错误，然后使用
document.getELementsByTagName（"错误"））
for Firefox，你不需要定义命名空间，但你必须写
document.getElementsByTagName（" my：error"）;
最好使用标准的HTML元素（p，span）和innerHTML。

the <erroris not standard HTML elements then different browsers have
diffent behavior on unknow tag
for IE, you should define a namespace for custom elements
(xmlns:my="http://xxxx....", then use my:error, then use
document.getELementsByTagName("error"))
for Firefox, you need not to define namespace, but you have to write
document.getElementsByTagName("my:error");
It''d better to use standard HTML element (p, span) and innerHTML.
