no need for extra () 

function getTextWidth(text, fontname, fontsize) {
         var one = text || false,
            two = fontname || false,
            three = fontsize || false;

        if (one) {

        }

        if (two) {

        }

        if (three) {

        }
    });

and then you can call getTextWidth('foobar', 'arial', '12px);

There is no need for var one = text; etc - "text" is already a variable available to your function

The correct syntax is -

function getTextWidth(text, fontname, fontsize){
     var one = text;
     var two = fontname;
     var three = fontsize;
}

You have incorrect syntax. See this for an example of how to declare a function with parameters:

function getTextWidth(text, fontname, fontsize) {
     var one = text;
     var two = fontname;
     var three = fontsize;
}

function getTextWidth(text, fontname, fontsize) {
     var one = text;
     var two = fontname;
     var three = fontsize;
    }

You need to remove the extra brackets at the end of your function before the first opening {. Then you need to remove the trailing bracket and semi-colon. It looks like you are mixing a JavaScript function with jQuery.

Just remove the () just before the { in your function, and replace the }); with };
