Question

I have a list of tags which all get added to a hidden input with name=”item[tags][]”

<input type="hidden" style="display:none;" value="first" name="item[tags][]">
<input type="hidden" style="display:none;" value="second" name="item[tags][]">
<input type="hidden" style="display:none;" value="third" name="item[tags][]">

How could i combine those hidden inputs to output

var tag_filter = first,second,third;

Answer 1

You can use name selector to access the input elements and use map function along with get and join to get the comma separated list of values.

Live Demo

var tag_filter = $('[name="item[tags][]"]').map(function(){
  return this.value;
}).get().join();
