javascript - avoid multiple clicks on a div -


it's sthg simple, still didn't find solution, avoid multiple clicks on button, before finishing ajax call.

here tried : 

<button id="btn_pay"></button>  $("#btn_pay").click( function() {     $('#btn_pay').prop('disabled', true);     stripe.card.createtoken(form, striperesponsehandler); });             var striperesponsehandler = function(status, response) {             $.ajax({                 type: "post",                 success: function(data){                    alert("success");                 },complete:function(){                     //we re-enable button                     $('#btn_pay').prop('disabled', false);                 }             });

problem : if click several times on button, many alerts appear, it's button still active, , many ajax call done instead of jsut 1 @ time..

any idea ?

you can control simple variable:

    <button id="btn_pay"></button>      var disabled = false; // global var control button state      $("#btn_pay").click( function() {         if (disabled) {             return;          }          stripe.card.createtoken(form, striperesponsehandler);         disabled = true; // button blocked     });      var striperesponsehandler = function(status, response) {           $.ajax({                     type: "post",                     success: function(data){                        disabled = false; // release button lock                        alert("success");                     },complete:function(){                        disabled = false; // release button lock                     },fail: function(){                        disabled = false; // when fail, need release lock                     }             });       }

other solutions event handlers may work too, simpler way implement feature.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
