Hi Guys,

I seem to be having troubles with the setAttribute syntax. All I want to do is update values in forms:

What am I doing wrong??

What happens when you execute that code? Any error? Do you have On Error Resume Next anywhere in your script?

Hi ,

AFAIK, there is no input type "form" (cf. http://www.w3.org/TR/html4/interact/forms.html#input-control-types).
Please try to test your code with a type like "text", and tell us about the results.

Good luck.

Thanks for your replies... I know that this is something so stupid... but, I can't get it to work!

All I'm trying to do is update the 'value' of input elements. I've tried input types 'button', 'form', and 'text'. I don't receive any errors... but, 'value' doesn't update either.

@ebgreen, I'm not using any sort of On Error Resume Next. I tried doing this in my code... and in the example you gave me from the other thread. This is what I'm trying to do:

When I run this example, the button still displays 'Old Caption'. Am I making a false assumption about how I can use the setAttribute method?

Thanks,

Brian

I would say just make the change when you create the element:

strButtonVal = "New Caption"
Set oButton = document.createElement("<INPUT TYPE='button' ID='btn1' VALUE='" & strButtonVal & "' ONCLICK='buttonClick()'>")

That's what I was trying at first... but, I got a little distracted by the constant redrawing...

Anyways, I found a solution:

Too bad setAttribute doesn't allow for this...

Anyways, hope this helps!

Hi MaddMan79,

again somebody too fast for me! But if you like to compare notes - ah codes ...

<html>
  <head>
   <hta:application id = "bootstrap"
   />
   <title>bootstrap</title>
   <meta http-equiv = "content-script-type" content = "text/vbscript"/>
   <script language = "VBScript"
           type     = "text/vbscript"
   >
 '<![CDATA[
 
 Option Explicit
 
 ''=
 ' ============================================================================
 
 Sub Window_OnLoad()
   MsgBox "Yes, Window_OnLoad() is called."
   Dim oDiv    : Set oDiv    = document.getElementById( "div1" )
   Dim oButton : Set oButton = document.createElement(                                            _
                   "<INPUT TYPE='button' ID='btn1' VALUE='Old Caption' ONCLICK='buttonClick()'>"  _
                                                     )
   oButton.Value = "New Caption"
 
   ExecuteGlobal "Sub buttonClick : MsgBox ""bootstripped!"" : End Sub"
 
   oDiv.appendChild oButton
 End Sub
 
 ''= refreshes the HTA page, which includes re-running any Windows_Onload code
 ' ============================================================================
 Sub reloadHTA()
   location.reload( True )
 End Sub
 
 ']]>
   </script>
  </head>
  <body>
   <input type = "BUTTON" value = "reload" onclick = "reloadHTA()">
   <hr />
   <div id="div1">
    <p>now there is nothing to see, but wait ...</p>
   </div>
  </body>
 </html>

And: I really would like to have a plausible explanation.

What did you want a plausible explanation of?

I was wondering why

     (1) Set oButton = document.createElement("<INPUT TYPE='button' ID='btn1' VALUE='Old Caption' ONCLICK='buttonClick()'>")
     (2) oButton.setAttribute "Value", "New Caption"

didn't work. Because somebody who doesn't state his questions clearly has to provide the answer
himself, I tried to think (always difficult!), did some tests, and googled until I could identify the
culprits:

(1) value is "VALUE" in line 1
(2) value is "Value" in line 2
(3) value is value (all lowercase) in HTML/DOM
(4) setAttribute( sName, vValue [, iFlags ] )
         iFlags = 0: ignore case
         iFlags = 1 (default): honor case
        [see http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/setattribute.asp]

Therefore

    oButton.setAttribute "Value", "New Caption", 0
    oButton.setAttribute "value", "New Caption", 1

are okay (tested).

ehvbs,

I had no idea that this was a case related issue! That was a good catch ;)

I'll admit... since I've been coding with VBScript, I've gotten a little more lazy about staying consistent with case. I'll watch out for that!

Thanks for taking the time to find the root of the problem

-Brian

Hear, hear. Excellent detective work.
