How do I remove spaces from start and end of catalog item string variable?

[swnewton]

Greetings,

I'm trying to write an onChange catalog client script to check a string variable for beginning and trailing spaces.  If found, give the user an error message and set the value to null.  Everything I've tried hasn't worked.  Does anyone have the code to accomplish this?

Thanks in advance!

I haven't tried this, but maybe use the 'trim' method. If you go this route, it would likely be better as an On Submit Client Script, otherwise it would run and run since you are setting the value on the same variable causing the on-change to run.

 
        var str = g_form.getValue('variable_1');
        var wsr = str.trim();
        g_form.setValue('variable_1',wsr );
