Answer 1

Problem : zoomsl does not work with jquery 3.3.1 version

Error :

Solution :

• You need to change new Image() .load() function in zoomsl-3.0.js

• Apply $("img").one("load", function() { ... } there

• Please check codepen example here

Old Code:

$.fn.imagezoomsl = function(options){
    options = options || {};        
    return this.each(function(){        
        if (!$(this).is("img")) return true;            
        var that = this;            
        setTimeout(function () {
            $(new Image()).load(function(){//this is old line
                sergelandimagezoomer.init($(that), options);
            }).attr('src', $(that).attr('src'));                
        }, 30);
    });
};

New Code:

$.fn.imagezoomsl = function(options){
    options = options || {};        
    return this.each(function(){
        if (!$(this).is("img")) return true;            
        var that = this;            
        setTimeout(function () {
            $("img").one("load", function() {//new code
                sergelandimagezoomer.init($(that), options);
            }).attr('src', $(that).attr('src'));                
        }, 30);
    });
};

You can see that $("img").one("load", function() { ... } is applied in setTimeout function.

Just change this line and it will start working.

This change will keep working in jquery older versions too.

I hope you found the solution, please fill free to ask question.
