Contains some nice jQuery plugins to make working with the facilities provided by the bootstrap CSS framework more fun.

Dialog Two, a jQuery dialog plugin based on the bootstrap modal dialog

jquery.dialog2.js uses the modal dialog provided by bootstrap and provides a controlable dialog functionality for web pages as a jQuery plugin.

Features

  • Ajax content
  • Ajax links and form submission in the dialog
  • Loading indicator
  • Localization
  • No dependencies to jQuery.UI
  • Control via html markup possible
  • Load an external URL (using iframe) inside the modal

Dependencies

Migrating from earlier versions

  • Migration from 1.x:
    • You will need bootstrap 2.x on your page
    • Change your css markup for forms according to the bootstrap 2.0 (buttons always require .btn, .primary to .btn-primary, .actions to .form-actions and so forth.

Controlling a dialog with JavaScript

  • $(selector | element | text).dialog2(options) creates a dialog with the given options from an element or selector. If the selected element exists, it will be turned into the body of the newly created dialog.
  • $(".selector").dialog2("method", argument1, argument2, ...) executes an API method (see below)

Options

The dialog2() method accepts an options object:

{
  id: "my-dialog", // id which (if specified) will be added to the dialog to make it accessible later 
  autoOpen: true | false, // Should the dialog be automatically opened?
  title: "Title of the dialog", 
  buttons: {
    button1Label: callback | object, 
    button2Label: callback, 
    ...
  }, 
  closeOnOverlayClick: true | false, // Should the dialog be closed on overlay click?
  closeOnEscape: true | false, // Should the dialog be closed if [ESCAPE] key is pressed?
  removeOnClose: true | false, // Should the dialog be removed from the document when it is closed?
  showCloseHandle: true | false, // Should a close handle be shown?
  initialLoadText: "" // Text to be displayed when the dialogs contents are loaded
}

When adding buttons to a dialog, a button options object can be passed to it instead of a callback:

{
  click: function() { }, // callback to execute on button click (has this bound to the dialog)
  primary: true | false, // if this button is the primary button (will be styled accordingly)
  type: "info" // basically additional classes to be attached to the button
}

API

  • open(): Opens the dialog (essentially shows it if it is still hidden)
  • close(): Closes the dialog and removes it from the document (if configured)
  • options(options): Applies the given options to the dialog
  • addButton(label, options): Adds a button with the given label to the dialog. If options is a function binds the click or "enter" action of the button to it. Accepts a button options object too to customize the look and feel of the button.
  • removeButton(label): Removes the button with the specified label from the list of buttons

Let the markup rule

The dialog has some distinct features which make it totally controllable via html markup.

  • When the jquery-controls plugin is added to a website, a.open-dialog links will open a dialog which shows in page or ajax content.
  • If the dialog content updates, a dialog will change its title to the contents of the first h1 element found in it. Additionally its buttons are updated based on the buttons found inside the .actions element of the dialog content.
  • .ajax forms will be submitted asynchronously and the result will be displayed in the dialog.

Changing the UI

Dialog width

Override the boostrap styles for .modal which are (as of version 1.3)

.modal {
    ...
    width: 560px;
    top: 50%;
    margin: -250px 0 0 -250px;
}

with your new styles for wide dialogs

.wide-modal {
    ...
    top: 20%;
    width: 800px;
    margin: 0 0 0 -400px; /* -1 * (width / 2) */ 
}

and add the class wide-modal to big dialogs.

Extending the dialog

A user may plug into the dialog behaviour by listening to events, namely

dialog2.ajax-start: fired right before an ajax request is started, 
dialog2.ajax-complete: fired when an ajax request was executed successfully, 
dialog2.content-update: when the dialogs contents are updated (after ajax-complete)

The preferred way to register handlers on these events is $().delegate. The code snipped shown below illustrates how this behaviour can be used to implement a auto-close ability for a dialog (see issue #19).

// If a a.auto-close is contained in the dialogs content, 
// the dialog will close itself automatically and (optionally)
// redirect to a new page
$(document).delegate(".modal", "dialog2.content-update", function() { 
     // got the dialog as this object. Do something with it!
     
    var e = $(this);
    
    var autoclose = e.find("a.auto-close");
    if (autoclose.length > 0) {
        e.dialog("close");
        
        var href = autoclose.attr('href');
        if (href) {
            window.location.href = href;
        }
    }
});
