indexOf()

@FangDec 29.2010 — #Provided [I]text [/I]is a global variable, the 1st alert will work, but it does not return a value, so the 2nd alert will show undefined.

@ashadjawaidauthorDec 29.2010 — #Hi

this is the whole program for finding the existence of a word in a file

it is giving an alert true or false with the function stated above

I need to store that value in a variable and then print the value through an alert i somehow succeeded to get pass it into the variable but it is giving me some random number instead of -1(in case word doesn't exist) or some +ve if word is there.

PLEASE ADVISE

<head>

<script language="JavaScript" type="text/javascript">

var text;

function fetchText(txtFile)

{

var d = document;

var txtFrame = d.getElementById( 'textReader');

txtFrame.src = txtFile;

setTimeout('text = getContent();', 500);

}

function getContent()

{

var d = document;

var txtFrame = d.getElementById( 'textReader');

var text = '';

if (txtFrame.contentDocument)

{

var d = txtFrame.contentDocument;

text = d.getElementsByTagName('BODY')[ 0].innerHTML;

}

else if (txtFrame.contentWindow)

{

var w = txtFrame.contentWindow;

text = w.document.body.innerHTML;

} 
  return text;

}

function doTest(txtFile, searchFor)

fetchText(txtFile);

var a = setTimeout("text.indexOf('" + searchFor + "')", 750);

alert('a:::'+a);

@FangDec 29.2010 — #[I]var a[/I] will be the id number of setTimeout. It's value is unpredictable and varies with each browser. It has nothing to do with indexOf.
