动态更改jQuery Mobile列表视图中的图标

例：

<ul data-role="listview" data-autodividers="true" data-filter="true" data-inset="true">
        <li data-icon="check"><a href="#">Adam KinKaid</a></li>
        <li data-icon="check"><a href="#">Alex Wickerham</a></li>
        <li data-icon="check"><a href="#">Avery Johnson</a></li>
        <li data-icon="check"><a href="#">Bob Cabot</a></li>
        <li data-icon="check"><a href="#">Caleb Booth</a></li>
        <li data-icon="check"><a href="#">Christopher Adams</a></li>
        <li data-icon="check"><a href="#">Culver James</a></li>
    </ul>

$("li").tap(function() {
    //Alert the old icon
    alert($(this).jqmData("icon"));

    //Toggle
    $(this).jqmData("icon") == "false" ? $(this).jqmData("icon","check") :             $(this).jqmData("icon","false");

    //Alert the new icon
    alert($(this).jqmData("icon"));
});
