Return a 'string' from javascript eval() function

Question

I am trying to evaluate an expression like a == b ? 'Ok' : 'Cancel'; using JavaScript eval() but is shows error.

Is there any way to execute and return string out of eval() ?

Regards, Nwbrd

Your error is likely related to a or b being not defined prior to calling eval(), for ex: the following code works fine with the eval() call returning a string as expected.

var a = 5, b = 6;
var result = eval("a == b ? 'SAME' : 'DIFFERENT'");
alert(result);
