javascript - Passing Array From PHP to JQuery json_encode -

i have html form generated php has dropdown of voucherproviders.

i want select provider , have populate form editing.

here jquery code:

$(document).ready(function() {      $(document).on('change','#id_voucherprovider',function(){         var voucher_providers = <?php echo json_encode($voucher_providers); ?>;          //the value have got drop down is....         var value = $('#id_voucherprovider option:selected').val();         var vendortext = $('#id_voucherprovider option:selected').text();         //so voucher provider         alert(vendortext);          $('.ftext input').val(vendortext);         $("textarea#id_vendornotes").val(voucher_providers[value]);     }); });  

voucherproviders not being passed jquery despite echo json_encode($voucher_providers); code working when inline php code.

it seems return null array. can see wrong?

many thanks

var voucher_providers = <?php echo json_encode($voucher_providers); ?>; 

json_encode returns string, unless parsed not usable. use jquery .parsejson , should have better results. :)

var jsonstring = <?php echo json_encode($voucher_providers); ?>; var voucher_providers = $.parsejson(jsonstring);
