Question

I have this ajax event

function save_response_with_ajax(t){
  var form = $('#edit_'+t);
  var div = $('#loading_'+t);
  $.ajax({
    url: form.attr("action"), 
    type: "POST",    
    data: form.serialize(), 
    cache: false,
    beforeSend: function(){
      form.hide();
      div.show();
    },
    complete: function(){
      div.hide();
      form.show();
    },
    success: function (result) {
    }       
  });
}

And everything works fine, but I want to add (if it’s possible) the hability of turning the entire page (the content/body) into gray while before/complete ajax events, like if it were a modal (like this http://jqueryui.com/demos/dialog/#modal but without the dialog)

Is there a way of doing this?

Thanks in advance

A way of doing this is having an overlay element which fills the entire page. If the overlay element has a semi-transparent background color, it grays out the page completely: http://jsfiddle.net/SQdP8/1/.

Give it a high z-index so that it’s on top of all other elements. That way, it renders correctly, and it catches all events (and won’t pass them through).

#overlay {
    background-color: rgba(0, 0, 0, 0.8);
    z-index: 999;
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    display: none;
