Can "starts with" be a condition within a Client Script?

[Edwin Fuller]

I need to write an onLoad Client script that checks if the parent field starts with a 3 letter prefix of "CUS". I have not has much success with this can someone show me how this would be written?

Thanks,

Edwin

Startwith does not work in client script.

You have to get the value using getValue and then check the string start with "CUS" using match function (Javascript)

Hi Edwin,

You can try like this:-

var a=g_form.getValue('field name');

if(a.startsWith('CUS'))

{

you code.......
}

else

{

}

I need to write an onLoad Client script 

Does it need to be a Client Script?  

What's the end objective?   If it meets this criteria... what then?

If the parent field starts with 'CUS' then I need to show a certain related list, otherwise I need to hide that related list.
