cakephp函数像JavaScript中的Set :: combine [英] cakephp functions like Set::combine in Javascript

问题描述

有没有一些javascript函数与浏览器中客户端的cakephp函数Set :: combine和Set :: classicExtract相同？
http://book.cakephp.org/2.0 /en/core-utility-libraries/set.html

这样我就可以使用这个数组：

  a = [
 {
'User'：{
'id'：2，
'group_id' 
'name'：'Alfred'
} 
}，
 {
'User'：{
'id'：12，
 'group_id'：2，
'name'：'Albert'
} 
} 
] 
  

使用

  Set :: combine（a，'{n} .User.id'，'{n} .User.name'）
  

p>

  a = {
 2：'Alfred'，
 12：'Albert'
} b $ b  

但是这不仅仅是为了这个简单的例子，我真的在寻找一个库或其他类似cakephp的方法。

strong>看到一个相当于CakePHP的Hash类的JS，但遗憾的是在一个小时的谷歌搜索后，我找不到任何东西... Underscore.js和Sugar.js都有一些过滤功能，但似乎都不工作的多维数组。

在蛋糕我经常做这样的事情。

  Hash :: extract（$ users，'{n} .User.Posts。{n} .Comments。{n} [published = 1]'）; 
  

如果任何人知道一个JS库这样做，将非常感谢提示。 >

编辑：我已经找到了一些选项，允许这种查询JSON数据

• JSPath
  
  .automobiles {.maker ===Honda&& .year> 2009} .model




• json ：select（）（受CSS选择器的启发）
  
  .automobiles .maker：val（Honda）.model p>




• JSONPath （受XPath启发更多）
  
  $。automobiles [？（@。maker ='Honda'）]。model

我认为JSPath看起来最好，所以我将尝试并将其与我的AngularJS + CakePHP应用程序集成。

Are there already some javascript functions that do the same as the cakephp functions Set::combine and Set::classicExtract on client side in the browser? http://book.cakephp.org/2.0/en/core-utility-libraries/set.html

So that I can bring this array:

a = [
   {
        'User' : {
            'id' : 2,
            'group_id' : 1,
            'name' : 'Alfred'
         }
    },
    {
        'User' : {
            'id' : 12,
            'group_id' : 2,
            'name' : 'Albert'
         }
    }
]

with a function like

Set::combine(a, '{n}.User.id', '{n}.User.name') 

into the format

a = {
  2 : 'Alfred',
  12 : 'Albert' 
}

for example. But it's not only for this simple example, I'm really looking for a library or something which can do it in a similar way to cakephp. Thanks a lot in advance!

解决方案

I would love to see a JS equivalent to CakePHP's Hash class, but sadly after an hour of Googling, I cannot find anything... Underscore.js and Sugar.js both have some filtering functions, but neither seem to work on multi-dimensional arrays.

In Cake I often do things like this...

Hash::extract($users, '{n}.User.Posts.{n}.Comments.{n}[published=1]');

If anyone knows a JS library that does this, would be very grateful for the tip.

EDIT: I have since found a few options that allow this kind of querying of JSON data (with examples of the syntax they use).

• JSPath
  .automobiles{.maker === "Honda" && .year > 2009}.model

• json:select() (inspired more by CSS selectors)
  .automobiles .maker:val("Honda") .model

• JSONPath (inspired more by XPath)
  $.automobiles[?(@.maker='Honda')].model

I think JSPath looks the nicest, so I'm going to try and integrate it with my AngularJS + CakePHP app.
