javascript - Trim strings before using map? -


i want input values page user has made , want store in array make ajax-call process data. i'm doing way:

$('#save').click(function(){     var data = $('*[data-array]').map(function(idx, elem) {     $.trim(elem);     return $(elem).val();     }).get();

the problem won't trim strings before creating array. seems $.trim doesn't apply? example if type abc____________ (_ being whitespace, have write here show whitespace demonstration) i'll result: abc_ (with 1 whitespace after abc)

you have trim value

$('#save').click(function(){     var data = $('*[data-array]').map(function(idx, elem) {     $(elem).val($.trim($(elem).val()));     return $(elem).val();     }).get(); 

 $('#save').click(function(){          var data = $('*[data-array]').map(function(idx, elem) {          $(elem).val($.trim($(elem).val()));          return $(elem).val();          }).get()                    console.log(data);          });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>  <input data-array/>  <input data-array/>  <input data-array/>  <input type="button" id="save" value="save"/>
