如何从html格式的iframe中检索信息? [英] How do I retrieve information from an iframe in an html form ?

问题描述

我有两个文件:
1. syllabusContent.jsp
2. syllabusRichTextEditor.jsp

syllabusContent.jsp 包含一个表单，我有一个

I have two files :
1. syllabusContent.jsp
2. syllabusRichTextEditor.jsp

The syllabusContent.jsp contains an form and I have an

<iframe>

元素，格式如下所示:

element in the form as shown in the code below:

<div>
Syllabus
    <iframe src="../syllabusRichTextEditor.jsp" width="1200" height="400"></iframe>
</div>

现在在我的 syllabusRichTextEditor.jsp 中，我有以下代码:

Now in my syllabusRichTextEditor.jsp I have the following piece of code:

<textarea id="tinyeditor" name="syllabus" style="width: 100%; height: 200px">
    ${sessionScope.coreCoursesBean.syllabus}
</textarea>

因此，当我尝试显示表单的内容时，它没有显示
中包含的字符串

So When I am trying to display the contents of the form it is not displaying the string contained in

${sessionScope.coreCoursesBean.syllabus}

其次，
当我单击Submit时，我甚至希望将在textarea中输入的课程表都提交给我的servlet，这不会暂停.

所以基本上我想知道如何在两个jsp之间进行通信?

secondly,
when I click on submit, I want even the syllabus entered in the textarea to be submitted to my servlet, which is not hapenning.

So basically I want to know how to communicate between two jsp`s?

推荐答案

{sessionScope.coreCoursesBean.syllabus} < /textarea >

{sessionScope.coreCoursesBean.syllabus} </textarea>
