Question

Is there a JavaScript version of the following. It works as I want, but it looks a bit messy and I’ve read that sometimes breaking from an outer for loop within a .each loop is more neatly achieved with Javascript.

for(array to iterate over){
    var abSelected = false;
    $("input[type='checkbox'][id*=AB]:checked").each(function() {
      abSelected = true;
    }
    if(abSelected){
      break;
    }
...do other stuff...
}

I think the if statement is unnecessary. I want to loop all checkboxes beginning with ‘AB’ and break from the outer for loop if any are selected.

Thanks.

Answer 1

you can simply check on the length of the selected checkboxes beginning with 'AB' collection returned by jQuery, if > 0, break:

for(array to iterate over){
    if($("input[type='checkbox'][id*=AB]:checked").length > 0)
        break;
...do other stuff...
}
