Disable a textbox by reference

[Daniel]

Hello,

I'm trying to enable/disable a textbox by reference but seem to be
having a great deal of trouble.

function enableField(EleName,EleVal)
{
// All controls in form 'usrsel'
// EleName = Name of the control to be disabled
// EleVal = Comparison string, value from the select control
alert("The control id is: " + EleName + " " + EleVal)

If (EleVal == 'Other')
{
document.usrsel.getElementsByName(EleName).disabled=false;
}
else
{
document.usrsel.getElementsByName(EleName).disabled=false;
}
}

The issue is I place the alert statement for troubleshooting. it work
and returns the value I send from the onchange event. However, The If
stament does not seem to trigger. Could someone help me get this
functional.

Thank you

Daniel

@o61g2000hsh.googlegroups.com:




is it because the "else" above is identical to the "if"?

me thinks one of them should be ".disabled = true;"

You are right about that, but it still doesn't work with that change.

function enableField(EleName,EleVal)
{
If (EleVal == 'Other')
{
document.usrsel.getElementsByName(EleName).disabled=false;
} else {
document.usrsel.getElementsByName(EleName).disabled=true;
}
}

What is even weirder is the following does not work either

function enableField(EleName,EleVal)
{
alert(EleName + " " + EleVal);
If (EleVal == 'Other') alert("The value is Other");
}

The first alerts works fine and return the proper values including the
fact that EleVal=Other, but the If statement does not trigger the 2nd
alert???

Ca someone explain what it is that I've done wrong.

Thank you,

um, case sensitivity?

try:
if (EleVal == 'Other') alert("The value is Other");
not
If (EleVal == 'Other') alert("The value is Other");

Could the problem be that the "If" should be "if"?

I think you may be right. I'm new to javascripting and didn't realize
that it was case sensitive!

Thanks for the help!

No,

The code should be (where == may need to be !=)

document.usrsel.getElementsByName(EleName).disabled = EleVal == 'Other'

And then there's no IF to get the case wrong of. Additional parentheses
optional.
