Question

I would like to have some variables that my for loop uses inside a function scope (not global).

I tried to wrap the for loop inside a function like this but it results in console error:

function() {
    var data = livingroomTableData;
    for(var i = data[0]; i < data[1]; i++) {
        var elemvalue = data[2] + format(i) + ".png";
        livingroomTableArray[i] = elemvalue;
    }
}

I would like the data variable to have the values of livingroomTableData only inside this for loop (not globally). In other loops I will input a different variable into the data variable.

Oh yes, and as you can probably tell, I’m a total newbie. :S

There is only function scope in javascript, block scope does not exist, so you can’t let the variable only inside the for loop. What you could do is to create a function scope.

Code example:

(function(livingroomTableData) {
    var data = livingroomTableData;
    //... the rest code
})(livingroomTableData);
