jQuery Mobile - Filter Text Selectmenu

说明

将 data-filtertext 设置为任何子 (<option> 元素) 的属性，这将用于筛选。

示例

以下示例演示了如何在 jQuery Mobile 中使用筛选文本选择菜单。

      <script>
         $.mobile.document
         .on( "selectmenucreate", ".filterable-select", function( event ) {
            var input,
            selectmenu = $( event.target ),
            list = $( "#" + selectmenu.attr( "id" ) + "-menu" ),
            form = list.jqmData( "filter-form" );
            
            if ( !form ) {
               input = $( "<input data-type='search'></input>" );
               form = $( "<form></form>" ).append( input );
               input.textinput();
               list
               .before( form )
               .jqmData( "filter-form", form ) ;
               form.jqmData( "listview", list );
            }
            
            selectmenu
            .filterable({
               input: input,
               children: "> option[value]"
            })
            
            .on( "filterablefilter", function() {
               selectmenu.selectmenu( "refresh" );
            });
         })
      </script>
   </head>
   
   <body>
      <h2>Filter Text Selectmenu Example</h2>
      <form>
         <div class = "ui-field-contain">
            <label for = "filter">Basic</label>
            
            <select id = "filter" data-native-menu = "false" class = "filterable-select">
               <option value = "de" data-filtertext = "Delhi">Delhi</option>
               <option value = "pu" data-filtertext = "Punjab">Chandigarh</option>
               <option value = "ch" data-filtertext = "TamilNadu">Chennai</option>
               <option value = "mu" data-filtertext = "Maharastra">Mumbai</option>
            </select>
            
         </div>
      </form>
