jQuery/Javascript Checkbox -

i want checkbox. if user clicks on checkbox, should change state (checked -> unchecked , vv. ).

my code:

$('#checkboxstandard').change(function() {     clickedformboxen('standard'); });   function clickedformboxen(active){ if(active == 'standard'){      if( $('#checkboxstandard').is(":checked")){          $('#checkboxstandard').prop("checked", false);      }else{          $('#checkboxstandard').prop("checked", true);     }      console.log('ac: '+$('#checkboxstandard').is(':checked')); } 

unfortunately, checkbox not unchecked again. fist time, checkbox getting checked, if click on again, nothing happens, it's still checked.

i wish use code can change state of checkbox function call , not user interaction.

please me , sorry english^^

try

$('#checkboxstandard').removeattr("checked");
