jquery - Enable button only if start and end dates are not empty -


initially button in disabled mode. when user selects both start , end dates should enabled download.

the below code enables button when start or end date selected. how enable download button when both inputs not empty applying class $('#btn_download').attr('class','btn-general');?

//enable 'download' button if start-end dates not empty var enabledisablebtn = function(){     var startval = $('#datepicker_start').val().trim();     var endval = $('#datepicker_end').val().trim();     var disablebtn =  startval.length == 0 || endval.length == 0;     $('#btn_download').attr('disabled',disablebtn);     $('#btn_download').attr('class','btn-general'); }     $('#datepicker_start').datepicker({     enabledisablebtn(); });  $('#datepicker_end').datepicker({     enabledisablebtn(); }); 
<button class="btn-general disabled" id="btn_download" type="button">     <span class="glyphicon glyphicon-download-alt" style="margin-right:5px;"></span>     download </button> 
.btn-general {     background-color: #6eb8d9;     color: #fff;     border: medium none;     border-radius: 6px;     cursor: pointer;     display: inline-block;     font-size: 15px;     line-height: 1.4;     padding: 6px 15px;     text-align: center;     vertical-align: middle;     white-space: nowrap; } .btn-general.disabled {     background-color: #5bc0de;     color: #fff;     pointer-events:none;     cursor:not-allowed;     opacity:0.40; }

use onclose option

called when datepicker closed, whether or not date selected.

script

var enabledisablebtn = function(){     var startval = $('#datepicker_start').val().trim();     var endval = $('#datepicker_end').val().trim();     var disablebtn =  startval.length == 0 || endval.length == 0;     $('#btn_download').prop('disabled',disablebtn).addclass('btn-general'); }     //set onclose $('#datepicker_start, #datepicker_end').datepicker({     onclose : function(){          enabledisablebtn();     } });  //call enabledisablebtn();
