FLEX：Actionscript：我可以從ArrayColletion中創建新的對象嗎？

Question

我有一個使用Actionscript的語法問題。我可以從ArrayColletion中創建新的對象嗎？

var tagsList:TagsListModel = new TagsListModel(new ArrayCollection([ 

    {new TagModel("News", 36, yearPopularity, false, true)}, 
    {new TagModel("Information", 18, yearPopularity, false, true)} 

]); 

這是我的錯誤：

1084: Syntax error: expecting colon before rightbrace. 

感謝

與new關鍵字創建對象時，你不需要花括號。

var tagsList:TagsListModel = new TagsListModel(new ArrayCollection([ 
    new TagModel("News", 36, yearPopularity, false, true), 
    new TagModel("Information", 18, yearPopularity, false, true) 
]); 

大括號是用於創建類型的對象Object

var tagsList:TagsListModel = new TagsListModel(new ArrayCollection([ 
    {tag:"News", x:36, yp:yearPopularity}, 
    {tag:"Information", x:18, yp:yearPopularity} 
]); 

以下是一個且相同的：

var a:Object = {value:10}; 
trace(a.value);//10 

var b:Object = new Object(); 
b.value = 10; 
trace(b.value);//10
