Dialog

A flexible javascript popup dialog.

dialog.open({
        title: 'Dialog Title',
        source: 'Body content can be (HTML, CSS selector, DOM element, or URL)',
    }).then(...);

Features

Easy to use.
Lazy loading (3kb initial page load).
Usable as a webpack/ES6 module or a pre-built browser bundle.
Handles multiple programming scenarios and content sources.
Simple HTML structure and easy custom styling using CSS3 variables.
Dialogs can be 'modal', and/or can be layered on top of each other.
Implements the 'Promise' interface, allowing sequential notifications.

Installation

Dialog is a javascript package built for and using the ES6 module system, but it's also provided as a pre-built, minified browser package (in this package's "dist" folder).

Browser

Download & copy this package's "dist" folder into your web server's public folder eg. public/js/dist/*.
Rename "dist" to "dialog" eg. public/js/dialog
Load the dialog script at the end of your web page (before the closing body tag) like this:

<body>
    ...

    <script src="/js/dialog/dialog.js"></script>
</body>
</html>

When the browser loads, dialog will be attached to the browser's global window object. Use it anywhere in your scripts like this:

<button>Target</button>

<script>
    dialog.open();          // Display the dialog cheat sheet

    ...

    dialog.closeLast();     // close the on-top dialog
    
    ...
    
    dialog.closeAll();

</script>

ES6 module

Install the dialog package into your project using npm:

$ cd to/your/project
$ npm install @aamasri/dialog

Then import and use it in your project's ES6 modules:

Static import

import dialog from 'dialog';

function helloWorld() {
    dialog.open({ title: 'Greetings', source: 'Hello World' });
}

Dynamic import

Leveraging Webpack's on-demand (lazy) loading and code-splitting:

import(/* webpackChunkName: "dialog" */ 'dialog').then((dialog) => {
    dialog.closeAll();
    
    dialog.open(...
});

Dialog Functions

dialog.open({ .. }).then((dialogElement) => { .. })    // create a new dialog

dialog.close(dialogElement)                            // close a specific dialog instance

dialog.closeAll()                                      // close all dialogs

dialog.closeLast()                                     // close the on-top dialog

Dialog.open Options

Here's another example with different options; eg. to load/display a fragment of the HTML returned by a URL:

    dialog.open({
             title: `${userName}'s User Profile`,
             source: userUrl,
             fragment: '.contact-info'
             modal: true,
             onClose: function() { alert: `Don't hesitate to call ${userName}!`; }
         }).then( function(dialogElement) {
             console.log('fyi the contact info dialog just launched');
             
             window.setTimeout( function() {
                dialog.close(dialogElement);
             }, 10000);
         });

Here's the full list of dialog.open options:

Option	Type	Description	Default
title	string \| undefined	dialog title, else source element title attribute	"Missing Title"
source	string \| object \| undefined	the content source: html content, selector, url, or element	usage instructions
fragment**	string \| undefined	selector by which to extract a portion of the source HTML
modal**	boolean \| undefined	dialog background blurring & dimming	false
iframe	boolean \| undefined	if the source is a url, whether to load it in an iFrame. Adds a full-screen link.	false
fullscreenUrl	string \| undefined	forces a full-screen button (or for case that the fullscreen url differs from the source url)	false
replace	boolean \| undefined	whether to close any existing dialogs or layer up	false
persistent	boolean \| undefined	whether ESC key or blur events close the dialog	false
onClose	function \| string \| undefined	callback function or eval(string) to execute after dialog dismissed
classes	string \| undefined	additional classes to apply to the dialog container element
attributes	string \| undefined	attributes to apply to the dialog container element eg. 'data-ignore-events="true"'

Notes

To create a chrome-less dialog (ie. one with no padding or header, where the specified content completely fills the dialog box), simply omit the title option.
If loading a URL fails then it may be due to a CORS issue (if it's for a different domain).

** it is recommended to use the "iframe" or "fragment" options when loading a URL that returns a FULL HTML document.
This is because HTML documents cannot be nested without an iframe; not specifying the "iframe" or "fragment" option will cause the dialog to reload the URL in an iframe (which may unnecessarily increase the dialog load time).

Dialog Styling

The dialog's default CSS styles may easily be themed to fit your application. Change any of these default styles in your CSS :root or body scope:

:root {
    --dialogBoxShadow: 0 0 28px #CCC;
    --dialogBoxShadow: 0 0 28px #CCC;
    --dialogBoxShadow: 0 0 28px #CCC;
    --dialogBackground: #FFF;
    --dialogBorder: 1px solid #DDD;
    --dialogBoxShadow: 0 0 28px #CCC;
    --dialogBorderRadius: 4px;
    --dialogFontFamily: Helvetica, Verdana, sans-serif;
    --dialogLineHeight: 1.8;
    --dialogTitleSize: 1.3rem;
    --dialogTitleColor: #888;
    --dialogTitleWeight: bold;
    --dialogModalBackground: rgba(170, 170, 170, 0.3);
    --dialogModalOpacity: 0.3;

Package Management

Dialog supports npm under the name @aamasri/dialog.

NPM

$ npm install @aamasri/dialog --save

Dependencies

Dialog depends on 2 external packages:

jquery
animejs
@aamasri/dom-utils

These dependencies are bundled (as separate pre-built 'chunks') in this package's "dist" folder.
Invoking the dialog() function will dynamically load these dependencies at run-time (if these scripts don't already exist on the page) and they'll be added to the global window object.

If your page already loads the jQuery, animejs, or @aamasri/dom-utils packages, dialog will use them instead.

Manual release steps

Increment the "version" attribute of `package.json`.
Re-build the browser output bundle...
```
npm run build-production
```
...and observe that webpack completed with no errors.
Test the bundle by loading page: "dist/index.html" in a browser.

Commit

git commit -a -m "Release version x.x.x - description"

Tag the commit with it's version number
```
git tag x.x.x
```

Change the "latest" tag pointer to the latest commit & push:

git tag -f latest
git push origin master :refs/tags/latest
git push origin master --tags

Publish to npm registry:
```
npm publish
```
