多维JavaScript数组组内的数据 [英] group data within a multidimensional javascript array

问题描述

我有一个是充斥着大量的冗余数据，我会通过元素中本身喜欢组合在一起多维数组的JavaScript ...

  //当前的阵列
PGROUP =（[日下午，名字]）; // [0] [0] = PM0，[0] [1] = NAME0 ... [n]的[0] = PMN，[n]的[1] = namen
 

我的目标是所有冗余点的，那么组的名称中筛选出进入连接到各自的名字的数组。

我试过的.grep，$ .filter几次失败的组合，并与underscore.js修修补补了一下，找到一个解决方案..但作为然而我想出空。

要解决任何指导，将大大AP preciated。

//当前阵列

  PGROUP [    [0]
    0：Whimpenny，瓦尔特
    1：105495​​-005_SMS M＆放大器; S选项1年
    ，    [1]
    0：Whimpenny，瓦尔特
    1：105495​​-005_SMS M＆放大器; S选项2年
    ，    [2]
    0：Sukumar，人员Prasanna
    1：DISA-JCSS /月的工作人员-SO＃203868]
 

//请求的结果。

  PGROUP [    [0] 0：Whimpenny，瓦尔特1：[105495​​-005_SMS M＆放大器; S选项1年，105495​​-005_SMS M＆放大器; S选项年2]    [1] 0：Sukumar，人员Prasanna1：DISA-JCSS /月的工作人员-SO＃203868]]
 

解决方案

下面是一个使用罗短跑一个实用的解决方案：

  VAR分组= _.map（_。GROUPBY（PGROUP，0），功能（EL）{
    返回[埃尔[0] [0]，_.pluck（EL，1）];
}）;

另外，你可以行修改重返以下产生的对象，而不是最终产品阵列，通过的Barmar ：

 ，返回{名称：EL [0] [0]，值：_.pluck（EL，1）};
 

I have a multidimensional javascript array that's filled with a lot of redundant data that I'd like grouped together by elements within itself...

// current array
pGroup = ([pm, name]); // [0][0] = pm0, [0][1] = name0 ... [n][0] = pmn, [n][1] = namen

My goal is to filter out all of the redundant pm's, then group the names into an array attached to their respective names.

I've tried several failed combinations of $.grep, $.filter, and have tinkered with underscore.js a bit to find a solution.. but as of yet I've come up empty.

Any guidance to a solution would be greatly appreciated.

EDIT:

// Current array

pGroup [

    [0]
    0: "Whimpenny, Walter"
    1: "105495-005_SMS M&S Option Year 1"
    ,

    [1]
    0: "Whimpenny, Walter"
    1: "105495-005_SMS M&S Option Year 2"
    , 

    [2]
    0: "Sukumar, Prasanna"
    1: "DISA-JCSS/Staff Aug-SO #203868" 

]

// requested result

pGroup [

    [0] 0: "Whimpenny, Walter" 1: ["105495-005_SMS M&S Option Year 1", "105495-005_SMS M&S Option Year 2"]

    [1] 0: "Sukumar, Prasanna" 1: ["DISA-JCSS/Staff Aug-SO #203868" ]

]

解决方案

Here is a functional solution using Lo-Dash:

var grouped = _.map(_.groupBy(pGroup, 0), function (el) {
    return [el[0][0], _.pluck(el, 1)];
});

Alternatively, you could change the return line to the following to yield objects instead of arrays in the final product, as suggested by Barmar:

return { name: el[0][0], values: _.pluck(el, 1) };
