javascript - nightwatchjs - how to wait till ajax call is completed -


i using nightwatchjs browser automation. 1 common usecase seeing is, of content in webpage updated through data ajax call. so, in testing, looking way hold testing until result ajax. not find api in nightwatch or selenium this.

i have tried waitforelementvisible, feel not suffice. happen if ajax call doesn't return data.

has tried before?

if know ajax path here way how can solved, idea attach 'ajaxcomplete' event client , match executed request path:

client     .timeoutsasyncscript(15000) // set async exec timeout     .click('.btn-submit') // ajax form submit     .executeasync(         function(targeturl, done){             var nightwatchajaxcallback = function(ajaxurl) {                 if(ajaxurl.indexof(targeturl) === 0) { // if url match notify script xhr done                     done(true);                 }             };              if(!window.nightwatchajaxinited) { // make sure ajaxcomplete attached once                  window.nightwatchajaxinited = true;                  $(document).ajaxcomplete(function(e, res, req) {                     nightwatchajaxcallback(req.url);                 });             }         },         ['/ajaxpath'], // expected xhr request path         function(status){             // executes once ajax done             client.verify.containstext('.entry', 'lorem ipsup...') // verify post created         }     );

here command named 'ajaxwait' created code above:

exports.command = function(targeturl, action, callback) {      this.timeoutsasyncscript(15000);      action();      this.executeasync(function(targeturl, done){          var nightwatchajaxcallback = function(ajaxurl) {             if(ajaxurl.indexof(targeturl) === 0) {                 done(true);             }         };          if(!window.nightwatchajaxinited) {              window.nightwatchajaxinited = true;              $(document).ajaxcomplete(function(e, res, req) {                 nightwatchajaxcallback(req.url);             });         }      }, [targeturl], function(status){          callback();     }); };

and call should this:

client.ajaxwait('/ajaxpath', function(){     // ajax form submit     client.click('.btn-submit') // ajax form submit }, function(){     // executes once ajax done     client.verify.containstext('.entry', 'lorem ipsup...') // verify post created })

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...
