JS needed to search for string in text

PaulShotgun · Jul 23, 2003

I need some JavaScript to go inside an HTML page that's generated by a CGI file that basically says 'If the text string 'blah blah' is included in this page, then display a dialog box'.

Is this very easy to do?

Could someone give me the code for this plase as I am a JavaScript newbie and haven't a clue where to start! Thanks!

Is this the kind of thing you're talking about?

Code:

<HTML>
<HEAD>
<SCRIPT>
function showBox(searchString)
{
 var bodyText = document.body.innerHTML;
 if(bodyText.indexOf(searchString) != -1)
  alert(&quot;'&quot;+searchString+&quot;' found on page!&quot;);
}//end showBox(var)
</SCRIPT>
</HEAD>
<BODY ONLOAD=showBox(&quot;KLMNOP&quot;)>
ABC DEFG HIJ KLMNOP, QRST UV WXYZ.
</BODY>
</HTML>

I don't know anything about CGI, so I'm assuming you can hardcode the text-of-interest into the showBox function call in the HTML as above.

'hope this helps.
