Putting controls in an array 1

snotmare · Apr 26, 2005

Hello all! I'm fairly new to HTML, so I appreciate a good explanation.

If I have a list of controls on my web page, text boxes for example, and I want to reference them as an array, how can I group them together? Can I do this in HTML, or must it strictly be within the scripting code? (I'm most familiar with VB, but can read through JScript if necessary)

Here is a sample to work off of...

Code:

<HTML>
<HEAD>
<TITLE>File Folder Security</TITLE>
<SCRIPT TYPE="text/vbscript">
Sub subInit()
    Document.frmTest.txtTest1.Value = "test1"
    Document.frmTest.txtTest2.Value = "test2"
    Document.frmTest.txtTest3.Value = "test3"
End Sub

</SCRIPT>
</HEAD>

<BODY>
<FORM NAME="frmTest">
<INPUT TYPE="Text" NAME="txtTest1" VALUE="">
<INPUT TYPE="Text" NAME="txtTest2" VALUE="">
<INPUT TYPE="Text" NAME="txtTest3" VALUE="">
</FORM>
<SCRIPT TYPE="text/vbscript">

Call subInit()

</SCRIPT>
</BODY>
</HTML>

So, I would like to do something such as this...

Code:

Sub subInit()
    Dim i

    For i = 1 to 3
        Document.frmTest.txtTest(i).Value = "test" & i
    Next
End Sub

Thanks all for your help, any tips/pointers will be appreciated!

it appears you want vbscript, but to do this in javascript, you'd do something like:

Code:

var allEls = document.forms['frmTest'].elements;
for (var i = 0; i < allEls.length; i++) {
    if (allEls[i].name.indexOf('txtTest') > -1)
        allEls[i].value = 'test' + i
}

For what you're trying to do, you will need scripting. The only "grouping" html can do is visually contextual by putting the input boxes in their respective fieldset. All manipulation of values for boxes must be done with scripting however. I would still advise you to think about what you're doing. If you're filling up variables with predetermined values, isn't there a better way to solve the problem. Last but not least, you might want to use JavaScript rather than VBScript, since VB is only supported in IE. So, unless you're cursed with the closed environment that needs to use IE, you should go with JavaScript for better cross browser compatibility.

Hello all!

Thanks for your input. I did find a solution shortly after I posted this (figures)...

Code:

For i = 1 To 3
    Document.All("txtTest" & i).Value = "test" & i
Next

The HTML doc I'm creating is strictly for inhouse, which we all use ie. However, it would be good experience to code something in jscript. I understand that ie and netscape are the two biggest browsers, but what about firefox and others that are new? Do they support jscript/vb?

Thanks!

JavaScript is standard dynamic client-side scripting language in html and is as such available in all (or most) browsers (though it can also be turned off in all/most browsers). Netscape is the same as FF or Mozilla, because they are all using the same engine. VBScript (client-side) is strictly a MicroSoft thing and is supported only by their products.

Ok, thanks for the info! I will try to use javascript from here out. It will be hard to break from vb though
