Baffling Safari Javascript Issue

Question

My code below works in firefox perfectly..but not in Safari. When I use the Safari debug it simply says there is a parse error, just after the first opening curly bracket {

function setVals4(class,val) 
{
    var array = document.getElementsByTagName("select");

    for (var g = 0; g < array.length; g++)
    {
        sel = array[g]
        //sel = document.myform.sel[g];

        for (i=0; i<sel.options.length; i++) 
        {
            //alert(sel.options[i].value)

            if (sel.className == class) 
            {
                if (sel.options[i].value == val) 
                {
                    sel.selectedIndex = i;
                }
            }       
        }       
    }
}

Can anyone figure out why? Help!

Answer 1

class is a reserved word in JavaScript, even though it isn't used for anything (it's listed as a "future reserved word" in the ECMA spec). If you change your parameter name to clazz (which is the usual thing) or foo or something, that should sort it out.

(There's also a missing semicolon after sel = array[g], but that's okay, the language allows semicolon insertion at that point. Still, best to include them, especially if you ever want to minify/pack/compress your code down-the-line.)
