Question

我在更新我的阵列方面遇到了一些问题，顺便说一句，这个问题是全局的。

这是我的代码：

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

这是我的全局数组，我可以从应用程序的任何地方访问它。

当我想更新数组时，问题出现了：

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

所以，在完成操作之后，我期待的数组是这样的：

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

但不知怎的，我得到了相同的数组，没有更新，

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

请帮帮我，我不知道我在这里做错了什么，

谢谢你，

您的代码是正确的，但是您不应该扩展Ti对象，因为会发生类似意外的事情。创建自己的对象，它将起作用。

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

等等。

建议您将应用程序保存在单个上下文中，以便能够从任何位置访问该对象。查看the forging titanium视频系列了解最佳做法。

我同意Jeff的观点，但是如果你想让上述方法工作，你将需要更新整个数组，你不能只更新元素。

因此，将数组读入新变量，更新特定元素，然后再次设置属性

在App.js中：

Ti.App.my_variable = 0;

在some_other_page.js中：

Ti.App.my_variable = 101;

在yet_another_page.js中：

alert( Ti.App.my_variable );

这会提醒101 !!
