javascript - How to get value from text input on blur of field -

-

this question has answer here:

i'm trying write javascript value 2 text inputs, should straightforward. amiss. here code:

<script>     jquery(function() {         jquery('#frompicker, #topicker').datepicker({ dateformat : 'yy-mm-dd' });          jquery('#submit').attr('disabled', 'disabled');          jquery('#topicker').on('blur', function() {             var fromdate = jquery('#frompicker').val();             var todate = jquery('#topicker').val();             console.log(todate);              if (fromdate !== '' && todate !== '') {                 if (isvaliddate(fromdate) && isvaliddate(todate)) {                     jquery('#submit').removeattr('disabled');                 } else {                     alert('you must enter dates in format "yyyy-mm-dd"');                 }             }          });     });      function isvaliddate(dt) {         if (dt.match(/^[0-9]{4}\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])/)) {             return true;         }     } </script>

when console.log(todate) however, empty string. if blur event again (focus , unfocus field data still in it), correct value. ideas why doesn't work first time?

the 2 text inputs have ids of #frompicker , #topicker , jqueryui datepickers.

solution:

what did wanted this:

jquery(function() { jquery('#frompicker, #topicker').datepicker({ dateformat : 'yy-mm-dd' });

    jquery('#submit').on('click', function() {         var fromdate = jquery('#frompicker').val();         var todate = jquery('#topicker').val();          if (fromdate !== '' && todate !== '') {             if (isvaliddate(fromdate) && isvaliddate(todate)) {                 // nothing             } else {                 alert('you must enter dates in format "yyyy-mm-dd"');                 return false;             }         } else {             return false;         }     }); });  function isvaliddate(dt) {     if (dt.match(/^[0-9]{4}\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])/)) {         return true;     } } </script>

i dont see reason code not work instead of blur event, try onselect event of datepicker instead

jquery('#topicker').datepicker( {     onselect: function(date) {         alert(date);         // other stuff     },     // .... );
