如何更新鈦中的全局變量？

我在更新我的數組，這是全球性的方式有一些問題。如何更新鈦中的全局變量？

這裏是我的代碼：

Ti.App.dinercolor=["#FF5A00","#007EFF","#dccdc0","#C2FF95","#A700FD","#dccdc0","#dccdc0","#5F9EA0","#dccdc0","#dccdc0","#22A000","#DCCDC0","#dccdc0","#FF003C","#dccdc0","#FF003C","#dccdc0","#22A000","#dccdc0","#FFF191"];

這就是我的全局數組，我可以從它從任何地方在應用程序訪問數據。

問題是當我想更新像數組：

for(var q=0; q<Ti.App.dinercolor.length; q++){Ti.App.dinercolor[q] = '#dccdc0';}

所以，數組我是手術多數民衆贊成完成後預計是這樣的：

Ti.App.dinercolor=["#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0","#dccdc0"];

，但不知何故，我我得到相同的陣列與更新，

Ti.App.dinercolor=["#FF5A00","#007EFF","#dccdc0","#C2FF95","#A700FD","#dccdc0","#dccdc0","#5F9EA0","#dccdc0","#dccdc0","#22A000","#DCCDC0","#dccdc0","#FF003C","#dccdc0","#FF003C","#dccdc0","#22A000","#dccdc0","#FFF191"];

請幫助我，我不知道w帽子我做錯了這裏，

謝謝,,

是否都是在同一個文件中執行的操作？簡要介紹一下你的文件結構（如Ti.includes等） – mkind

你的代碼是正確的，但你不應該延長鈦對象作爲這樣意想不到的事情會發生。創建你自己的對象，它會工作。

myObj = {}; 
myObj.dinercolor = [];

依此類推。

建議您將應用程序保存在一個上下文中，以便您可以從任何地方訪問該對象。查看the forging titanium視頻系列，瞭解一些最佳做法。

我同意傑夫，但是如果你想要上述方法的工作，你將需要更新整個數組，你不能只更新元素。

所以讀出的數組出到一個新的變量，更新的特定元素，然後再次

設置屬性在App.js：

Ti.App.my_variable = 0;

在some_other_page.js：

Ti.App.my_variable = 101;

In yet_another_page.js：

alert(Ti.App.my_variable);

這將提醒101！
