I have an HTML textarea, and an IFrame. On a button click, I would like to be able to load the content of the textarea into the IFrame.

For example, when the user types in Hello World into the textarea, and presses the submit button, the text Hello World would show up in the IFrame.

Any ideas on how this could be done? Thanks in advance.

NOTE: I would like to use JQuery, but I think I'll have to use PHP for this. It sounds more server side.

我有一个HTML textarea和一个IFrame。 点击按钮,我希望能够将textarea的内容加载到IFrame中。

例如,当用户在textarea中键入 Hello World 并按下提交按钮时,文本 Hello World 将 出现在IFrame中。

关于如何做到这一点的任何想法? 在此先感谢。

注意:我想使用JQuery,但我想我必须使用PHP。 这听起来更像服务器端。

    You can target the iframe with jquery only:

       <script type="text/javascript">
       jQuery(document).ready(function() {
          jQuery('#btnSubmit').click(function () {
             var content = $("#test").val();
       <textarea name="test" id="test" rows="5" cols="40"></textarea>
       <button id="btnSubmit">Post to iFrame</button>
       <iframe name="iframe1" id="iframe1" src="test2.html"></iframe>

    Your iframe content page, in this case "test2.html" would have something like this:

      <p>[intro text or whatever]</p>
