javascript - Find resultant of two asynchronous ajax request in xhr onprogress -

-

i trying find images in ajax request response text , fetch src url using in ajax request.

i need know progress of loading each image , show resultant of progress in progress bar. can see if image1 loaded 10%; , image2 20%.

my result decreases 20% 10% . progress bar goes backward , goes forward.

any help? or solution?

parseresult: function(result, navnumber) {    var self = this;    var imagesmatter = $(result).find('img');    var imageslength = imagesmatter.length;      // if there image in ajax request fetch imgs using ajax show progress bar    if (imageslength >= 1) {      var = 0,        complete = 0,        temp = 1;      navigation.progress.fadein(50);        imagesmatter.each(function() {        var $this = $(this);        var url = $this.attr('src');          $.ajax({          url: url,          xhr: function() {            var xhr = new window.xmlhttprequest();            xhr.addeventlistener("progress", function(evt) {              if (evt.lengthcomputable) {                var percentcomplete = parsefloat(evt.loaded / evt.total).tofixed(1);                temp = complete + (percentcomplete / imageslength);                console.log(parseint(temp * 100) + '%');                navigation.progress.html(parseint(temp * 100) + '%');              }            }, false);            return xhr;          },          complete: function() {            complete = temp;                        i++;            if (i == imageslength) {              self.closeloading(navnumber);            }          }        });      });    } else {      return;    }  }

here have removed complete variable of yours, can' understand purpose of it, , added local variable lastpercent each request, remember it's last progress percent perticular image request, on new update add new percent , remove old percents... hope logic clear you...

parseresult: function(result, navnumber) {   var self = this;   var showpercent;   var imagesmatter = $(result).find('img');   var imageslength = imagesmatter.length;    // if there image in ajax request fetch imgs using ajax show progress bar   if (imageslength >= 1) {     var = 0,       temp = 1;     navigation.progress.fadein(50);      imagesmatter.each(function() {       var $this = $(this);       var url = $this.attr('src');       var lastpercent = 0;        $.ajax({         url: url,         xhr: function() {           var xhr = new window.xmlhttprequest();           xhr.addeventlistener("progress", function(evt) {             if (evt.lengthcomputable) {               var percentcomplete = parsefloat(evt.loaded / evt.total).tofixed(1);               temp = temp + (percentcomplete / imageslength) - lastpercent;               lastpercent = (percentcomplete / imageslength);               showpercent = temp/imageslength;               console.log(parseint(showpercent * 100) + '%');               navigation.progress.html(parseint(showpercent * 100) + '%');             }           }, false);           return xhr;         },         complete: function() {           i++;           if (i == imageslength) {             self.closeloading(navnumber);           }         }       });     });   } else {     return;   } }
