jquery-app v1.6.0

jquery-app

Declarative jQuery plugin initialization on DOM elements. Finds elements, which has data-plugin attribute and calls jQuery plugins on them passing settings/options as first argument.

On repeated .app() calls if plugin already was initialized on the element then it will be ignored.

Install

Install with npm or yarn:

$ npm install jquery-app --save

$ yarn add jquery-app

Usage

List of plugins which will be called are defined by settings data-plugin="PLUGIN_NAMES" attribute on elements. Plugin names are either comma or space separated list of plugin names.

<!-- data-PLUGIN_NAME="JSON_CONFIGURATION" -->
<input
    type="text"
    data-plugin="datepicker"
    />

Plugin settings

Settings/options for plugin can be set either using data-PLUGIN_NAME="JSON_CONFIGURATION" attribute

<!-- data-PLUGIN_NAME="JSON_CONFIGURATION" -->
<input
    type="text"
    data-plugin="datepicker"
    data-datepicker='{"numberOfMonths": 3, "showButtonPanel": true}'
    />

or specific data-PLUGIN_NAME-PROPERTY="VALUE" attribute

<input
    type="text"
    data-plugin="datepicker"
    data-datepicker-number-of-months="3"
    data-datepicker-show-button-panel="true"
    />

In this example under the hood jquery-app will call plugin passing options as

$(INPUT_ELEMENT).datepicker({
    "numberOfMonths": 3,
    "showButtonPanel": true
});

Call jquery-app to initialize plugins

$(function () {
    // Find all elements with data-plugin attribute inside body and initialize plugins
    $('body').app();
});

In some cases you may want to use different attribute name than data-plugin, that can be done using namespace property when calling $.fn.app

$(function () {
    // Find all elements with data-attach attribute inside body and initialize plugins
    $('body').app({
        'namespace': 'attach'
    });
});

Multiple plugin support

Multiple plugins can be defined using space or comma separated list and since options are prefixed there won't be collision between options/settings for each plugin.

<div
    data-plugin="pluginA, pluginB"
    data-pluginA-option-a="alpha"
    data-pluginA-option-b="beta"
    data-pluginB-option-a="gamma"
    data-pluginB-option-c="delta"
    ></div>

Under the hood jquery-app will call plugins as

$(DIV_ELEMENT).pluginA({
    "optionA": "alpha",
    "optionB": "beta"
});
$(DIV_ELEMENT).pluginB({
    "optionA": "gamma",
    "optionC": "delta"
});
