javascript - jQuery hover images carousel timeout overlaps -

-

i'm building webpage shows products. when hovering on product image, slideshow-like event should start. you'll see photo's of product in several states. i've coded jquery , i'm facing kinda annoying bug.

when hover on several products fast , leave mouse on 1 product, slide through images fast.

the html structure looks this:

<div class="products">   <div class="productcontainer" data-product-id="1">     <img src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside.jpg" class="mainproductimage" />     <div class="hoverimages">       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside-1.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside-2.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside-3.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside-4.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/inside/bmw-inside-5.jpg" />     </div>   </div>   <div class="productcontainer" data-product-id="1">     <img src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside.jpg" class="mainproductimage" />     <div class="hoverimages">       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside-1.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside-2.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside-3.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside-4.jpg" />       <img src="" data-lazy-src="http://detestdivisie.nl/upload/images/hover-tests/outside/bmw-outside-5.jpg" />     </div> </div> </div>

the javscript class responsible handling events looks this:

categoryproductimages = function () {   this.classname = 'categoryproductimages';   this.version   = '0.1.0';    this.mouseover         = false;   this.currentelement    = null;   this.currentcategoryid = 0;   this.currentimagelist  = [];           this.currentimagekey   = 0;    /**    * categoryproductimages.init()    *    * initializes class reponsible handling    * mouse on , outs products.    *    * method call createobserver method.    */   this.init = function () {     console.log('called ' + this.classname + '.init()');      this.createobservers();   };    /**    * categoryproductimages.createobservers()    *    * handle mouse on , out events.    */            this.createobservers = function () {     console.log('called ' + this.classname + '.createobservers()');      var thisobj = this;      jquery('.productcontainer').hover(       /** called when mouse of user moves on element. **/       function () {         console.log('mouse on .productcontainer');          thisobj.mouseover         = true;                             thisobj.currentelement    = jquery(this);            thisobj.currentcategoryid = thisobj.currentelement.data('category-id');                           console.log('lets\'s work category id ' + thisobj.currentcategoryid);          thisobj.currentelement.find('.hoverimages img').each(function() {           thisobj.currentimagelist.push(jquery(this).data('lazy-src'));         });          thisobj.iterate();                 },       /** called immediatly after mouse of user leaves element **/       function () {         console.log('mouse out .productcontainer');          thisobj.currentelement   = null;         thisobj.mouseover        = false;                             thisobj.currentimagelist = new array();         thisobj.currentimagekey  = 0       }     );   };    this.iterate = function () {     console.log('called ' + this.classname + '.iterate()');      if (this.mouseover && this.currentimagelist.length > 0) {       console.log('will start iteration process');        this.currentelement.find('img.mainproductimage').prop('src', this.currentimagelist[0]);        thisobj = this;       settimeout(function () {         console.log('first image shown, show next image.');          thisobj.nextimage(thisobj.currentcategoryid);       }, 3000)     } else {       console.log('won\'t iterate, because mouse of user has left element, of there no images show.');     }       };    this.nextimage = function (currentcategoryid) {     console.log('called ' + this.classname + '.nextimage()');      if (this.mouseover && this.currentimagelist.length > 0 && currentcategoryid == this.currentcategoryid) {       console.log('mouseover still active, , images found, show next image.');        this.currentimagekey += 1;        if (typeof this.currentimagelist[this.currentimagekey] == 'undefined') {         console.log('oh no! we\'ve reached end of list. letst start on again.');          this.currentimagekey = 0;       }        this.currentelement.find('img.mainproductimage').prop('src', this.currentimagelist[this.currentimagekey]);        thisobj = this;       settimeout(function () {         console.log('okay, we\'ve waited 3 seconds, next! :)');          thisobj.nextimage(currentcategoryid)       }, 3000);     } else {       console.log('iteration ' + currentcategoryid + ' stopped');       console.log('mouse over: ');       console.log(this.mouseover);       console.log('image list length: ');       console.log(this.currentimagelist.length);       console.log('nextimage category id: ');       console.log(currentcategoryid);       console.log('current category id:');       console.log(this.currentcategoryid);       console.log('#########################');     }   } };  var categoryproductimagesobject = new categoryproductimages(); categoryproductimagesobject.init();

the make more clear i've created codepen example. please mouse on product 1 , product 2 fast , leave mouse on product 1. you'll see loop through product images way fast.

http://codepen.io/wdivo/pen/lamsq

the time should take before , image replaced 1 3 seconds. overlooking something, because several settimeouts working near eachother, while there should 1 active settimeout.

what should make sure 1 "active" settimeout running?

simply said, i'd want stop previous settimeouts if new 1 gets activated.

i'm looking clearinterval, can't think of way implement it...
