Question

for(var i=1; i<496; i++) {
    (function(num) {
        myApp.getTerm(num, function (term, def){
            myApp.quizlet[0].terms[num] = { term: term, definition: def};
        });         
    })(i);
};

I’m calling a function with callback inside a for-loop. The callback function need to access the current loop’s iteration i. I’m coming up with the solution above.

Is there any other way to do things like this?

Answer 1

It’s more readable to define a named function to call:

myApp.getTermForQuizzlet = function(num){
    myApp.getTerm(num, function (term, def){
        myApp.quizlet[0].terms[num] = { term: term, definition: def };
    });         
};

for(var i=1; i<496; i++) {
    myApp.getTermForQuizzlet(i);
};

Other than that, I don’t know what you can do.
