jQuery UI—The Dialog: Part 1

by Dan Wellman | February 2009 | Content Management Open Source PHP

Traditionally, the way to display a brief message or ask a visitor a question would be to use one of JavaScript's native dialog boxes, such as alert or confirm, or to open a new web page with a predefined size, styled to look like a dialog box. Unfortunately, neither of these methods is particularly flexible or engaging. For each problem they solve, several new problems are usually introduced.

Thankfully, the days of resorting to either of the aforementioned techniques are over. We can now make use of the advanced functionality and rich features of the jQuery UI dialog widget. The dialog widget lets us display a message, supplemental content (like images or text), or even interactive content (like forms). It's also very easy to add buttons, such as simple ok and cancel buttons, to the dialog and define callback functions for them in order to react to their being clicked.

In this first part of the article by Dan Wellman, we will complete the following tasks:

  • Create a basic dialog
  • Create a custom dialog skin
  • Work with dialog's properties
  • Enable modality and see an overlay
  • Add buttons to the dialog
  • Work with dialog's callbacks.
