jquerymy.js ‹{}›

A lightweight jQuery plugin for complex two-way
data binding in real time.


How jquerymy works 

jQuery.my is a plugin for real time two-way data binding. It mutates object given as a data source, reflecting interactions between user and UI.

Data bindings, facade appearance and CSS styling of an app are all defined using single manifest, which is standard javascript object. Manifests are JSONable.

jQuery.my recognizes both standard HTML controls and complex composites created using rich ui plugins. Controls built with jQuery UI, Select2, CodeMirror, Ace, Redactor, CLeditor, jQuery Mobile are supported out of the box.

jQuery.my provides comprehensive validation, conditional formatting, complex dependencies, runtime form structure manipulation. $.my forms can run nested, each jQuery.my instance can be a composite control for parent form.

Syntax of $.my manifest is very simple, lean and unobtrusive. There exist specialized in-browser IDE for $.my apps authoring. This IDE is a built-in component of cloudwall.me system.


Use Code button to edit source code of examples. Use Run button to exec your edits. To mention, code editors and sandboxes are also $.my apps. On this particular page $.my manages ~300 running instances, type $(".my-form") in console to see them all.

Page layout

Use handles  to drag pages and blocks around. Layout you build is continuously stashed under AdLayout key into localStorage, so you can reload page and take your layout back.

Application itself (without HTML and CSS) is about 100 sloc long and contains 3 nested manifests – app, page and block. Undo is built-in feature of $.my. Draggable items are created using jQuery UI Sortable.

Interactive table

Data is requested when app starts, and then indexed locally for faster search. All texts in the table are clickable.

Stats source – www.av1611.org. Range control is built using jQuery UI Slider.

Map and loupe

Carta Marina is 500 years old map of North Europe. jQuery UI Draggable plugin applied to manage loupe drag. Movement lag is intentional.

Mobile platforms may fail to show 5x zoom – image is too large for mobile browsers, sorry.

Bézier curve

All control points are draggable, jQuery UI Draggable plugin is applied to manage them.

This demo reflects state to localStorage. Reload page – curve shape remains the same. 

TodoMVC demo

This example is built using specs of TodoMVC project. Below code is the shortest implementation. Standalone version – jQuerymy.com/todomvc.

Prebuilt HTML and CSS used. They are excluded from manifest for their size (450 sloc). 


This demo shows how to create inter-linked lists that produce master-detail UI pattern. Elements of left list are draggable; notice how item number changes on drag. Right list always consit of a single element, that is editable reflection of an element selected at left.

The property init of right list‘s manifest illustrates how to use $.formgen plugin syntax to draw a form. $.formgen is shipped with $.my.

All controls

The form contains nearly all supported controls. Ace and CLeditor are not shown, but supported as well.

The form also illustrates how $obj.modal() works. Click control’s type to popup control’s init code. 


Works perfect in all modern browsers and IE11+.

Try it yourself

To run any demo as a standalone page just wrap manifest with this code:

<!DOCTYPE html>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <!-- General stylesheet -->
    <link rel="stylesheet" type="text/css" 
          href="http://cdn.cloudwall.me/1.2/general.css" />
    <!-- Contains Sugar, jQuery, jQuery.my -->
    <script src="http://cdn.cloudwall.me/1.2/minimal.js"></script>
    <!-- Contains different rich ui plugins -->
    <script src="http://cdn.cloudwall.me/1.2/plugins.js"></script>
    <div id="cw-body">
      <div id="form" class="p50 w750">
        <!-- Container for app -->
      // onload
        // Manifest goes here
// Place your javascript here
/* Container for CSS code */

An entire set of libs is ~280 Kb gzipped, $.my takes 24Kb.

Plugin set plugins.js incorporates a lot of rich UI libs, not necessary needed in every single app. Minimal set of libs required to run $.my forms is <100Kb gzipped.
