Accessing dynamic text boxes..

Rebies · Jun 20, 2002

I have searched high and low, and can't quite figure this out. Any help would be appreciated.

I have X number of text boxes on a page. It is always changing, but I do have the total number stored in a hidden text box titled 'loops'. The text boxes are named in the fashion of:

quant1
quant2
quant3

and so forth. I am trying to create a loop that will read the contents of each text box and check for a match with 'xyz'. Note: The following does not work, but is what I am trying to do:

<script language="JavaScript">

</script>

Hello Andrew:

I hope this helps:

Rename your text boxes to the same name,let's say quant1.If you do that, a new array of text boxes is created.The array name would be quant1,and you can easily locate wich text box contain the value "xyz".

Here is the example:

<html>
<head>
<script language="JavaScript">
function CheckValue()
{
for(i=0;i<document.myform.quant1.length;i++)
{
if(document.myform.quant1.value=='xyz')
alert('Match found in text box number '+eval(i+1));
}
}
</script>
</head>
<body>
<form name="myform">
<input type="text" name="quant1" value="Value1">
<br>
<input type="text" name="quant1" value="Value2">
<br>
<input type="text" name="quant1" value="Value3">
<br>
<input type="text" name="quant1" value="xyz">
<br>
<input type="text" name="quant1" value="Value5">
<br>
<input type="button" name="mybutton" value="Check Values" onclick="CheckValue()">
</form>
</body>
</html>

I hope this helps.

Kindest Regards

\\ also
function show_val(where, who)
{
a = document.getElementById(where).getElementsByTagName(who);
for(b=0;b<=a.length;b++)
{
alert("alert number " + b + " : " + a.value);
}
}

\\ later
<form id="form_name" ...>
\\\ call the function like this example
<a href="javascript:show_val('form_name', 'input')">test</a>

Well, both could work, but the fact is I can't change the names of the text boxes to the same thing because of Cold Fusion processing at the other side. (Things would get really confusing - not knowing which text box belongs to which set of data)

Also, I have multiple hidden fields and checkboxes, so the 2nd idea wouldn't work without some heavy workarounds.

Is there a way in JavaScript (as I do it in ColdFusion) to dynamically say:

#evaluate("quant#i#&quot

#

This returns the information stored in quant1, quant2 (ow whatever i currently is).

Thanks for your help. I'm sure there is a way of referencing this information, just can't find out the proper way.

Sorry BB101:

I meant to respond saying thanks. That is exactly what I was looking for and it makes me so happy knowing I wasn't crazy in looking for that one method of doing it.
