Error handling demo

When a JavaScript error happens because of server error/incorrect url (500, 404) the only way you would know the reason is by using something like firebug/chrome dev tools (by looking in the console for the execution of ajax requests).

You can also assign a js function to the awe.err, this way whenever an error will occur your custom function will be executed.

awe.err = function(o, xhr, textStatus, errorThrown) {
    var msg = "unexpected error occured";
    if (xhr) {
        msg = xhr.responseText;
    }
    msg += "(you see this message because in Site.js awe.err is set to a function that shows this popup)  ";
    var btnHide = $('<button type="button"> hide </button>').click(function() {
        $(this).parent().remove();
    });

    var c = $('<div/>').html(msg).append(btnHide);

    //decide where to attach the inline popup
    if (o.p && o.p.isOpen) { // if helper has popup and is open
        o.p.d.prepend(c); // put msg inside popup div
    } else if (o.f) {
        o.f.html(c); // put msg inside control field
    } else $('body').prepend(c);
};

clicking on this popup links will throw a server exception, click on them to see how it's handled
