filebrowser.php giving error with submitLink

[ccbangler]

When we try to link an image we get a Js error
Error: this.$ is undefined on line 11 in ckeditor.js

this is the function:

Code:

function submitLink($funcNum, $url) {
                    if(window.opener){
                window.opener.CKEDITOR.tools.callFunction($funcNum, $url);
            }
                window.close();
    }

This is the link to the code:

Code:

<a class="primarylink" onclick="submitLink(1,'http://website.com/data/uploads/employee-portraits/image-name.jpg')" href="javascript:void(0)" title="Select file: image-name.jpg">image-name.jpg</a>
