Hi, is there some posibility how to read inner text from IFRAME on server-side ?

Not using InnerText or InnerHtml, but you can use some sort of screen scraping technique. Check out System.Net.WebRequest Class (example on how to do it in this link).

Hope that helps!

am afraid the innerText and innerHTML is the text between <iframe>and</iframe>

 <iframe id ="frame1" runat ="server" src ="Web.Config">123</iframe> the innerText and the innerHTML is 123

if you want to get the content of the iframe, using javascript

You can get the content of a iframe using two different methods.

First, you can use the windows's frames list to get a reference to a specific frame. For example:


This line will get the first frame in the window and return its document. You can also replace the index with a name corresponding to the name attribute on an iframe.

In chrome installed applications, you can also use the contentDocument property of the iframe. The following demonstrates both methods. Both variables 'method1' and 'method2' will have the same value.


function getContent()
  var method1 = window.frames['hello'].document;

  var iframe=document.getElementById("hello");
  var method2 = iframe.contentDocument;

<iframe id="hello" name="hello" src="hello.xul"/>

I guess I have a related question, so I will ask it here.

I can access the content of the iframe using above trick.

However, how can I change the content?

I tried self.window[2].document.body.innerText = "abc";

but does not seem to work.

Any ideas?

I think u can assigned it from server side

 <iframe id="if1" runat="server" src="Web.Config">123</iframe>

 <iframe id="if1" runat="server" src="Web.Config">123</iframe>


Now I'm curious; what good would that do exactly? Your code would change the text between the opening and closing iframe tag from "123" to "abc". That has nothing to do with the actual content of the iframe. The content between the opening and closing iframe tag is what gets displayed in a browser not supporting frames.

 Actually I need to do it on the client side using JavaScript.

I am not worried about other browsers at this stage since it's an intranet application and we use IE internally.



12/28/2006 12:31:54 PM


first sorry for misunderstandingEmbarrassed

try this, it should work

<iframe id="if1" src="" mce_src=""></iframe>

 <a href="" onclick="document.getElementById('if1').src='';return false;">ABOUT me</a>


12/29/2006 3:36:52 AM

There is a simple solution to this problem ,you have just get ID of the IFrame and Set the Contents of the Body


function setContent() { if (iView.document.body) { iView.document.body.innerHTML =""; iView.focus(); } }

 function GetContent() { document.Form1.hdContent.value=iView.document.body.innerHTML; document.Form1.submit(); }

Where IView is the ID of th IFRAME , and these are the JS functions .

Jscript, moving from client-side to server-side (.NET)
Hey all I’m working translating a web-app written in client-side Jscript to run on the server-side as JScript.NET. Without needing to get too specific, I am using Jscript because the original page aggregated raw data to produce statistical results (this was done dynamically based on user 'sort-by' options). The final output is an html report that can be emailed. Because this is currently being done on the client side, as the raw data grows the load-time grows as well (to the point that has almost become unusable). I’m posting here to see if anyone has any experi...

Validation Controls in .NET ( Client side or server side?)

web forms with client and server side controls??
Hi, I have a form that has client and server side controls. I have a problem in that any client controls (textbox) within the form runat="server" can not be accessed with client side code. Anyone got any ideas why and what work arounds are possible. Regards, Graham. once a form element is inside a <FORM> tag, you can no longer refer to it by its ID alone. you have to refer to it by formname.elementid or document.all.elementid. use document.getElementById(yourtextboxid) to get a ref to the element in the form. using this allows u to bypass the formname. but you must have dom compliant browser like IE. i use a wrapper function to get objects in my clientside scripting... something like... //////////////////////////////////////////////// // find an element and return object for it function getRef(id) { try { return document.getElementById(id); } catch (error) { var sAlert = 'ERROR: fnc {getRef} return the following error: \n '; sAlert += '[ ' + error.number + '] - ' + error.description; alert(sAlert); } } a little bit over the top but saves a lot of typing...

communication between client side(java script) and server side in .net project
I have a question which is, when building a .net project, we are able to use server side code and client side code(java script). How do they communicate?

For example, if I'm going to put an HTML table on a page, how do I decide whether or not to use a server control?  Should the server side always be chosen or if there is not explicit server side functionality required is it better to opt for a "normal" client side table? Obviously, if there is a need for server side control the question is answered, I'm looking more at more ambiguous situations. Thanks  This is from Micros...
