Hiyaの作業デモ http://jsfiddle.net/Yvnfx/ またはアラートなし:http ://jsfiddle.net/Yvnfx/1/ 削除にも注意を払う http://jsfiddle.net/wbQZU/4/
したがって、動作に関しては、Javaを選択した場合aotocomplete
、使用可能なタグにJavaは表示されません。
重要なのは、その配列を作成してからusedItems
、new array = existing array - used items
Jqueryコード
**var usedItems = []**
:
:// then
source: function(request, response) {
//===<> Read: build new array with = AvailableTagsArray - UsedItemArray
var newNonDuplicatetag = $.grep(availableTags, function(el){return $.inArray(el, usedItems) == -1});
// delegate back to autocomplete, but extract the last term
response($.ui.autocomplete.filter(
newNonDuplicatetag, extractLast(request.term)));
},
