[jQuery] Re: Check if a variable is set?

I think you mean: if (var === undefined) Note the === and no quotes around undefined. Karl Rudd On Wed, Nov 19, 2008 at 11:34 AM, Hector Virgen <[EMAIL PROTECTED]> wrote: > I usually check if the variable == 'undefined': > if (var == 'undefined') { > // var is not set > } > I don't know if

[jQuery] Re: Check if a variable is set?

I usually check if the variable == 'undefined': if (var == 'undefined') { // var is not set } I don't know if jQuery has one but it'd be simple to write your own. This is untested but might work :) $.extend({ isset: function(var) { return (var != 'undefined'); } }); -Hector
