javascript - Continuing for loop only when image loads - 


function readxml(){     var xmldoc = loadxml();     var x = xmldoc.getelementsbytagname("image");     (i = 0; < x.length; i++) {         if (i == 600){             break;         }         var path = x[i].getelementsbytagname("path")[0].childnodes[0].nodevalue;         var title = x[i].getattribute("class");         this.imagearray.push(new infoimage(path,title));         while(this.imagearray[i].isimageloaded() == false); //something         console.log(this.imagearray[i].getmaxpixels());      } }  function infoimage(path,title){     this.path = path;     this.title = title;     this.color = undefined;     this.maxpixels = undefined;     this.imageloaded = false;      this.init = function(){         var canvas = document.queryselector("canvas");         var img_color = new image_processing_color(canvas);         var img = new image();         var info_image = this;         img.onload = function () {             img_color.init(img);             info_image.color = img_color.getdominantcolor();             info_image.maxpixels = img_color.getdominantcolorpixels();             info_image.imageloaded = true;         };         img.src = path;     };      this.isimageloaded = function(){         return this.imageloaded;     }      this.getpath = function(){         return this.path;     };      this.gettitle = function(){         return this.title;     };      this.getcolor = function(){         return this.color;     };      this.getmaxpixels = function(){         return this.maxpixels;     };      this.init(); }

i want for loop continue next iteration when img.onload completes. while i'm using blocks code , doesn't let img.onload complete. there way this? without changing code structure.

you can check .complete property of img:

var x = document.getelementbyid("myimg").complete; result can true or false
