FCKeditor firefox Ajax提交,内容为空.解决.

The editor's content is empty when submitting the editor's surrounding form by ajax. What is wrong?

This problem is caused by a missing call of the function FCK.UpdateLinkedField(). By submitting the editor's surrounding form with an ajax function the values of all form elements are collected in a javascript object (some kind of an array). At this time the value of the hidden field that usually contains the editor's html output is empty, because the editor's surrounding form wasn't submitted for real, you can call it a simulated submit. The workaround is to call the FCK.UpdateLinkedField() function before submitting the form. Either you call it directly before the ajax collect function or in the onClick attribute of the submit button. For general use, even if you have more than one FCKeditor instance, I wrote the following hack to solve the problem.

// Some Class

function MyClass()

{

this.UpdateEditorFormValue = function()

{

for ( i = 0; i < parent.frames.length; ++i )

if ( parent.frames[i].FCK )

parent.frames[i].FCK.UpdateLinkedField();

}

}

// instantiate the class

var MyObject = new MyClass();

• Now can call this method in the onSubmit attribute of the editor's surrounding form before calling the ajax collecting function:

<form ... onSubmit="MyObject.UpdateEditorFormValue(); Ajax.Collect(); return false;">

Note: the previous syntax won't work if using VisualStudio 2005 and Atlas and IE. It will be ok to use :

<form ... onSubmit="MyObject.UpdateEditorFormValue(); return true;">

Or you'll do it in the onClick attribute of the submit button, which is also called before the onSubmit event:

<input type="submit" ... onClick="MyObject.UpdateEditorFormValue();" />

以上为FCKeditor官方原文。ajax提交含有FCKeditor的表单的时候。在firefox会忽略吊用FCK.UpdateLinkedField()函数。不能及时把iframe的内容赋值到隐藏表单域中。从而提交给服务器端。

解决方法就是在点击提交按钮的时候,循环遍历一下form中的iframe,并且吊用iframe.contentWindow.FCK.UpdateLinkedField()方法.
