ExtJS中是否有map（）函数？ [英] Is there a map() function in ExtJS?

问题描述

ExtJS有Ext.each（）函数，但是还有一个map（）也隐藏在某个地方？

我已经尝试过，但没有找到任何可以填补这个角色。这似乎是一件简单而简单的事情，一个像Ext这样大的JS库必须有。

或者Ext真的不包括它，那会是什么最好的方法来添加到Ext。当然，我可以写：

  Ext.map = function（arr，f）{...}; 
  

但这真的是正确的方法吗？

解决方案

看来，我这里的大学正在使用 ext-basex ，它使用map（）和其他方法扩展了Array.prototype。

所以我可以写：

  [1，2，3] .map（function（）{...}）; 
  

问题解决。

ExtJS has Ext.each() function, but is there a map() also hidden somewhere?

I have tried hard, but haven't found anything that could fill this role. It seems to be something simple and trivial, that a JS library so large as Ext clearly must have.

Or when Ext really doesn't include it, what would be the best way to add it to Ext. Sure, I could just write:

Ext.map = function(arr, f) { ... };

But is this really the correct way to do this?

解决方案

It appears, that my colleges here are using ext-basex, which extends Array.prototype with map() and other methods.

So I can just write:

[1, 2, 3].map( function(){ ... } );

Problem solved.
