Opening modal alert window from element javascript?

[juuser]

Hi,

Would it be possible to open a jquery modal alert window from element onchange event. E.g. if element value = "1" then alert "Something"

This is what I have right now, but I'm having difficulties of implementing this.

jQuery.extend({ alert: function (message, title) {
  jQuery("<div></div>").dialog( {
    buttons: { "Ok": function () { jQuery(this).dialog("close"); } },
    close: function (event, ui) { jQuery(this).remove(); },
    resizable: false,
    title: title,
    modal: true
  }).text(message);
}
});

jQuery.alert("message", "title");

Thanks in advance
