JScript link to network share Dynamics CRM 2015 online

Hi everyone,

Since the update from CRM 2013 to CRM 2015 my jscript who allow to open with a double click a Windows explorer with a network path value not working anymore.

I try to figure out what is wrong without sucess.

Here the jscript:

function OnLoad()
{
    Transform("new_dossierrseau1");
}

function Transform(fieldid)
{
    var c = document.getElementById(fieldid);
    if (c == null)
        return;

    c.style.textDecoration = "underline";
    c.style.color = "blue";
    c.style.cursor = "hand";
    c.ondblclick = function()
    {
        window.open(Xrm.Page.getAttribute(fieldid).getValue());
    };
}

Thanks for your help
