Jquery Javascript only works on chrome and firefox, but not on IE

Question

I have a HTML file which contains CSS and Jquery. When I tested it on chrome and Firefox, it works fine. But when I tested it on IE, only the CSS part work, the click function in JavaScript doesn't work at all.

$(document).ready(function(){

    var prev;       
    $('svg polygon').click(function(){
        var current = this;
        this.classList.add('mouseclick');
        $('#suburb').val(current.id);


        if((typeof prev != 'undefined') && (current != prev)){
            prev.classList.remove("mouseclick");
        }


        prev=current;
    });

    $("#forwardbutton").click(function(){
        $("#ctlform").submit();
    });

});

svg polygon{
    fill:none;
    stroke: white;
    stroke-width:1px;    
}

svg polygon:hover{
    fill: rgba(255, 255, 0, 0.3);
}

svg polygon.mouseclick{
    fill: rgba(255, 0, 4, 0.3);      !important;
    stroke-width: 1px;
    stroke: rgb(255, 0, 4);
}

Solution:
classList.add() is not compatible in IE.
So change it to .attr("class", "classname") will solve the problem.

Answer 1

I'm going to guess it's the usage of classList which only has partial support, starting in IE10. What does your developer tools -> scripts in IE tell you, it should give you an error.

Further more, why are you using jquery AND native JS. I hate jquery personally, but a big reason to use it is for the cross browser support, you could just use the class methods in jquery.

Answer 2

As Shan suggested , your problem is your use of classList ; however, jQuery cannot add a class to an SVG . You can hack your way around this though by setting the class attribute on the <svg> .

You can see this in action by running the snippet below.

 $(document).ready(function(){ var prev; $('svg polygon').click(function(){ var current = this; $(this).attr("class", "mouseclick"); $('#suburb').val(current.id); if((typeof prev != 'undefined') && (current != prev)){ $(prev).attr("class", ""); } prev=current; }); $("#forwardbutton").click(function(){ document.getElementById("ctlform").submit(); }); }); 

 svg polygon{ fill:none; stroke: white; stroke-width:1px; } svg polygon:hover{ fill: rgba(255, 255, 0, 0.3); } svg polygon.mouseclick{ fill: rgba(255, 0, 4, 0.3); !important; stroke-width: 1px; stroke: rgb(255, 0, 4); }

Answer 3

You must have a cached version of jQuery in your FF and Chrome cache, because I do not see you including jQuery anywhere on the page.

Add to page just below BODY tag:

<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>

EDIT:

I see you added it now. I just tested your code snippet with the jQuery lib loaded and it works in IE11.

PS - Cool effect!

Answer 4

Sorry, but I don't see the JQuery import <script src="//code.jquery.com/jquery-2.1.1.min.js"></script> .

Note JQuery 2.* doesn't work with IE 6/7/8
