Hi All,

I have a for mon my page, and initially when the page loads all the controls are readonly. when the user clicks an edit button, a vbscript sub will set all the controls to writeable again. The problem I am facing is, that after setting al lthe controls to writeable, I can't type into the textboxes unless I first press the INSERT key on my keyboard.

Can anyone tell me how to overcome this problem or if its not possible, how to simulate an INSERT key press?Thanks in advance.

Try it with this method which is cross browser compatible with NS and IE, us the Blur effect


<script language="JavaScript">
function changeReadOnly(){
    for (i = 0 ; i < document.myForm.elements.length ; i++){
         document.myForm.elements[i].onfocus="";}}
</script>

<form name=myForm>
<input type=text name=a OnFocus="this.blur()">
<input type=text name=b OnFocus="this.blur()">
<input type=text name=c OnFocus="this.blur()">
<input type=button onClick=changeReadOnly()>
</form>

Hi gary,

Do you have something liek that in Vbscript? Also, The onfocus="" doesn't change the readonly status right? I am nto sure how to change the readonly status in vbscript so I can't really test your solution!

The onFocus stops the fields being editable, does it need to be compatible with earlier versions of NS?  Try my example as it is now (just that code) and you will see what I mean.

No what I need to do is, For each control in the form

Set it to WRITEABLE (Readonly=False)
Allow entry without having to press the Insert key

Can you show us some of your code of how you set all the controls to ready only?  This might help us to help you to set your controls to writable, without pressing the Insert button on your keyboard (since there is not a way to simulate the Insert button on your keyboard from a web page).

It is something like this :

<script language="VBScript">
sub editrecord()
document.mrForm.a.readonly=false
end sub
</script>

<form name=myForm>
<input type=text name=a readonly>
<input type=button onClick=editrecord()>
</form>

Does it have to be vbscript, try my example in my previous example, it's almost identical and does the same thing except it works without having to press the Insert key

I don't think this works :

<script language="JavaScript">
function changeReadOnly(){
    for (i = 0 ; i < document.myForm.elements.length ; i++){
         document.myForm.elements[i].style.readonly=false;}}
</script>

<form name=myForm>
<input type=text name=a style="readonly:true">
<input type=button onClick=changeReadOnly()>
</form>

Because when I load a page containing only that code, the textbox is not readonly. I think the stye="readonly:true" doesn't work.

I took your code segment and copied/pasted it into an asp document on my web server.  However the code worked fine (with the exception of the mrform which should have been myform), and I was not able to duplicate the error you are getting as far as the need to press Insert.  I'm wondering, maybe there is something else in your code that is causing it.  To find out, have you tried testing the simplified code segment you posted above?  Stick that into an asp page and let us know if that still forces you to press Insert.  If it doesn't, then there must be something else in your code that is causing it.  If it does, then I'd say it is something specific to your system.
Let us know.

You are right! It must be something else in the page that is causing the requirement to press insert, any ideas on what might cause something like that?

Winny,
What is happening is this:  You've got a maxlength on each of your input boxes and they are being filled from the recordset (rs).  When you populate the input boxes, they are being filled with blank spaces after the value.  All you need to do is trim them... for example:
value='" & rs("caddr1") & "'
becomes:
value='" & trim(rs("caddr1")) & "'

This should take care of your problem.  Let me know if it doesn't.
