Question

Ok so I do this:

<input type="checkbox" class="checkBoxClass" value="0" />
<input type="checkbox" class="checkBoxClass" value="1" />
<input type="checkbox" class="checkBoxClass" value="2" />

Then in javascript/jquery I’m trying to do something like this:

$('#btnHtml').click(function(){
for( var checks=''; $('.checkBoxClass:checked').val() ){
    var checks = checks+', ';
}
});

Let’s say all of those checkboxes are checked, how can I get var checks to be a string of '0, 1, 2' ?

Still trying to get used to the for() in JS, it might be the completely wrong way of going about it. Not sure how to do this.

Functional programming:

var str = $('.checkBoxClass:checked').map(function() {
    return this.value;
}).get().join();

Reference: .map, .get, .join
