我在使用 JQuery UI 对自动完成结果进行排序时遇到问题。 
从上图中，当用户决定搜索大蒜并开始输入“g”时，它应该首先显示“大蒜”而不是鸡蛋。
查看我的代码。 ingredient.txt 中的成分按字母顺序排序，所以我认为这就是问题所在..
我该怎么做
$(function() {
jQuery.get('ingredients.txt', function(data) {
var availableTags = data.split(', ');
availableTags = availableTags.sort();
//console.log("The available Tag are "+ availableTags);
function split( val ) {
return val.split(",");
}
function extractLast( term ) {
return split( term ).pop().sort();
}
// don't navigate away from the field on tab when selecting an item
$( "#tags" ).bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB && $( this ).autocomplete( "instance" ).menu.active ) {
event.preventDefault();
}
}).autocomplete({
minLength: 0,
source: function( request, response ) {
// delegate back to autocomplete, but extract the last term
response( $.ui.autocomplete.filter(
availableTags, extractLast( request.term ) ) );
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function( event, ui ) {
var terms = split( this.value );
// remove the current input
terms.pop();
// add the selected item
// var projectDiv = '<div class="projectBody" id="selectedItems">'+ ui.item.value +'</div>';
terms.push( ui.item.value );
for(var i = 0; i < terms.length; i++) {
var elements = terms[i];
}
// add placeholder to get the comma-and-space at the end
terms.push( "" );
//$("#tags").val().wrap( "<div class='new'>nn</div>" );
this.value = terms.join( "," );
return false;
}
});
});
});
