jqueryui dialog positioning

Question

I am using JQuery UI and would like to position my dialog horizontally centered but vertically above center, maybe by a fixed amount of pixels or a relative distance from the top of the page. Is there an easy way to do this? It looks like there are just a couple pre-defined values or I can use an exact position but is there an easy way to accomplish this?

 $("#dialog-form").dialog({
                autoOpen: false,
                width: 630,
                position: 'center',
                modal: true,
                resizable: false,
                closeOnEscape: false

            });

Answer 1

Use the position option to align the top of the dialog with the top of the window (plus a pixel or percent offset).

This should center the dialog horizontally and position it 150 pixels from the top.

$("#dialog-form").dialog({
    autoOpen: false,
    width: 630,
    position: { my: 'top', at: 'top+150' },
    modal: true,
    resizable: false,
    closeOnEscape: false
});

Older versions of jQuery UI used an array containing an [x,y] coordinate pair in pixel offset from left, top corner of viewport (e.g. [350,100]).

var dialogWidth = 630;
$("#dialog-form").dialog({
    // ...
    width: dialogWidth,
    position: [($(window).width() / 2) - (dialogWidth / 2), 150],
    // ...
});
