    Searching text in a frame

    Hi all - newbie question I'm afraid.

    I have a page that access an iframe:

    Code:
    <IFRAME ID="viewFrame" TITLE="Document Content Frame" SRC="/edrms/llview.exe/Foglight%20user%20journey%20test.html?func=doc.View&amp;nodeId=54782851&amp;docTitle=Foglight%20user%20journey%20test&amp;vernum=1" NAME="viewContent" HEIGHT="90%" WIDTH="100%"></IFRAME>
    The source of that frame is:

    Code:
    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
    <html>
    <head>
    <LINK REL="stylesheet" TYPE="text/css" HREF="/img/style/screen.css">
    <LINK REL="stylesheet" TYPE="text/css" HREF="/img/admin.css">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
     
    <BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#003366" VLINK="#660033" ALINK="#3300FF">
     
    <p><font size="3" face="Times New Roman">it's_alive!</font></p>
    What I want to do is search for the text 'it_alive!' from a script in our monitoring engine.

    I have the following code, but it fails and gives me a Unterminated String constant' error in javascript!

    Code:
    var TEXT_TO_FIND="it's_alive!";
    var elem =document.getelementbyid('viewFrame');
    
    if(elem.InnerHTML.indexOf(TEXT_TO_FIND) > -1)
    Any help with this gratefully received.

    Regards

    Justyn

    var elem = document.getElementById("viewFrame");
    var content = elem.contentWindow.document.body.innerHTML;
    this will give you the whole content from the iframe all you need to do is, now search that particular string in that content

    this works..

    var elem = document.getElementById("viewFrame");
    var content = elem.contentWindow.document.body.innerHTML;
    if(content.indexOf("it's_alive!") != -1)
    {
    alert ('its alive');
    }
    else
    {
    alert ('its dead sad');
    }

    Perfect pradzz7. Many, many thanks.

    Also nice to see I was on roughly the right track.
