<h1>jQuery Related Selects Plugin</h1>
<ul>
<li><a href="http://github.com/ehynds/jquery-related-selects">Documentation & download</a> at GitHub</li>
<li>My original <a href="http://www.erichynds.com/jquery/jquery-related-dependent-selects-plugin/">blog post and comments</a></li>
</ul>
<p>Note that in examples 1-6, the file that supplies the data <b>pauses for 1 second</b> so you can see the loading messages.</p>
<h2>Example 1</h2>
<p>The state select is pre-populated, and the rest will populate based on preceding values. Each select is configured with a custom loading message, and the default option text is set to "Choose an Option".</p>
<form id="example-1">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA">Massachusetts</option>
<option value="VT">Vermont</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
<select name="townID">
<option value="">Choose Town »</option>
</select>
<select name="villageID">
<option value="">Choose Village »</option>
</select>
</form>
<h2>Example 2</h2>
<p>The state and county selects are pre-populated and legitimate values are selected. Since the 'County' select already has a selected option,
the 'Town' select automatically populates. Individual selects do not have any custom settings. No defaultOptionText override.</p>
<form id="example-2">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA" selected="selected">Massachusetts</option>
<option value="VT">Vermont</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
<option value="BARN" selected="selected">Barnstable</option>
</select>
<select name="townID">
<option value="">Choose Town »</option>
</select>
<select name="villageID">
<option value="">Choose Village »</option>
</select>
</form>
<h2>Example 3</h2>
<p>The state select is populated, and the HTML structure of the other three are completely empty when the page loads.</p>
<form id="example-3">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA">Massachusetts</option>
<option value="VT">Vermont</option>
</select>
<select name="countyID"></select>
<select name="townID"></select>
<select name="villageID"></select>
</form>
<h2>Example 4</h2>
<p>Basic, just two selects.</p>
<form id="example-4">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA">Massachusetts</option>
<option value="VT">Vermont</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
</form>
<h2>Example 5</h2>
<p>Using the onChange, onLoadingStart & onLoadingEnd callbacks.</p>
<form id="example-5">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA">Massachusetts</option>
<option value="VT">Vermont</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
<div> </div>
</form>
<h2>Example 6</h2>
<p>Using the DisableIfEmpty option & the onEmptyResult callback.</p>
<form id="example-6">
<select name="stateID">
<option value="">Choose State »</option>
<option value="TX">Texas</option>
<option value="SC">South Carolina</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
<select name="townID">
<option value="">Choose Town »</option>
</select>
<div></div>
</form>
<h2>Example 7</h2>
<p>Retreiving data in HTML format instead of JSON. This option gives you more control of the options, like the ability to add optgroups. <a href="datasupplier.htm">View the data file.</a></p>
<form id="example-7">
<select name="stateID">
<option value="">Choose State »</option>
<option value="CA">California</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
</form>
<h2>Example 8</h2>
<p>Usage of multiple related select groups within the same form.</p>
<form id="example-8">
<select name="stateID">
<option value="">Choose State »</option>
<option value="MA">Massachusetts</option>
<option value="VT">Vermont</option>
<option value="TX">Texas</option>
</select>
<select name="countyID">
<option value="">Choose County »</option>
</select>
<select name="industryID">
<option value="">Choose Industry »</option>
<option value="HARDWARE">Hardware</option>
<option value="SOFTWARE">Software</option>
</select>
<select name="subindustryID">
<option value="">Choose Sub-Industry »</option>
</select>
</form>
</body>
</html>
