this is not working it is saying startsWith is not a function.

how can I get this to work. I need to disable a button if the string starts with Admin@

[CODE]
function(sm, row, rec) {
if (rec.get(‘objname’).startsWith(“Admins@”)) {
Ext.getCmp(‘deleteButton’).disable()
}
else Ext.getCmp(‘deleteButton’).enable();
}
}
[/CODE]

can someone show me a way to ge this to work

thanks

@Declan1991Dec 08.2008 — My personal preference would be using regular expressions like thisif (/^Admins@/.test(rec.get('objname'))) {But I think this would work as well<i>
</i>if (rec.get('objname')[b].substring(0,7) == "Admins@"[/b]) {
I cannot this of any other way to do it.

(/^Admins@/.test(rec.get('objname')))

works perfect.

the second on I tried earlier but after the @ the string could be any length depending on what the user adds in there.

but hte first way worked great.

thanks
