jQuery Mobile Listview Widget (Editable Listview)

Download Demo


Editable Listview (jQuery Mobile Plugin)


A customized version of the jQuery Mobile Listview Widget that supports insertion of new list items and removal of existing list items out of the box.


Why


Many a times, you come across a situation where you want to allow editing of list items. To do this simple task, you have to build extra functionality around the Listview widget to allow for insertion of new list items and removal of existing list items. Editable Listview plugin is designed to take the pain out of this situaiton by having all this functionality baked-in.


Features


  1. Allows insertion of new list items right in the Listview.

  2. Allows easy removal of existing list items.

How to Use it!


There are two ways you can install the plugin.


  1. Download and unzip the package into your project folder OR install using bower

    bower install jqm-editable-istview


  2. Include the plugin script after the jQuery Mobile source file

    <script src="jquery.mobile.editablelistview.js" type="text/javascript"></script>


  3. Include the plugin stylesheet right after the jQuery Mobile stylesheet

    <link href="../jquery.mobile.editablelistview.css" rel="stylesheet" type="text/css">


Simple Type


Use the following HTML/DOM structure


<ul data-role="listview" data-editable="true">
<li>Apple</li>
<li>Banana</li>
<li>Cranberry</li>
<li>Cherry</li>
</ul>

See below for a full list of available “data-” attributes


Complex Type


For complex type, link a form to the listview through data-editable-form attribute by putting in the id of the form as the value. That form will be shown embedded in the collapsible listview in Edit Mode. The user is at liberty to make the form look however they feel like, but they are supposed to add some specific data attributes to form elements. See the working example below.


<ul data-role="listview" data-editable="true" data-editable-type="complex" data-editable-form="editing-form">
<li>
<a>
<h3>Apple</h3>
<p><em>Shape:</em> <strong>round</strong></p>
<p><em>Color:</em> <strong>red</strong></p>
</a>
</li>
<li>
<a>
<h3>Pineapple</h3>
<p><em>Shape:</em> <strong>oval</strong></p>
<p><em>Color:</em> <strong>yellow</strong></p>
</a>
</li>
<li>
<a>
<h3>Orange</h3>
<p><em>Shape:</em> <strong>round</strong></p>
<p><em>Color:</em> <strong>orange</strong></p>
</a>
</li>
</ul>

<form id="editing-form" data-editable-form="true">
<input type="text" data-item-name="fruitName" data-item-template="<h3>%%</h3>">
<input type="text" data-item-name="fruitShape" data-item-template="<p><em>Shape:</em> <strong>%%</strong></p>">
<input type="text" data-item-name="fruitColor" data-item-template="<p><em>Color:</em> <strong>%%</strong></p>">
<button class="ui-btn ui-corner-all" data-add-button="true">Add</button>
<button class="ui-btn ui-corner-all" data-clear-button="true">Clear</button>
</form>

data-item-name is the name of the variable to hold the value of the input field. data-item-template holds the HTML template that will be used to render the new value. Use %% as placeholder for the variable. data-add-button indicates the button that can be clicked/tapped/pressed to insert the new list item having values specified in the input fields. data-clear-button clears all the text from the input fields.


Roadmap


This is a preliminary list of planned fatures.


  1. In-place editing of existing list items.

  2. Re-ordering of list items tap and hold on the list item and drag it back and forth.

  3. Deleting item by swiping left or right.
