来自json的Javascript定制对象

Question

我正在用highcharts脚本创建图表，并且我创建了一个php脚本，我正在用ajax调用它。该脚本返回json数据，我需要以highcharts基本列格式重新格式化它。

[{"count":"391","search_date":"2015-11-24","search_area":"lastni-pre"}, 
{"count":"63","search_date":"2015-11-24","search_area":"letalske"}, 
{"count":"501","search_date":"2015-11-24","search_area":"pocitnice"}, 
{"count":"114","search_date":"2015-11-24","search_area":"potovanja"}, 
{"count":"457","search_date":"2015-11-25","search_area":"lastni-pre"}, 
{"count":"103","search_date":"2015-11-25","search_area":"letalske"}, 
{"count":"509","search_date":"2015-11-25","search_area":"pocitnice"}, 
{"count":"84","search_date":"2015-11-25","search_area":"potovanja"}, 
{"count":"399","search_date":"2015-11-26","search_area":"lastni-pre"}, 
{"count":"106","search_date":"2015-11-26","search_area":"letalske"}, 
{"count":"385","search_date":"2015-11-26","search_area":"pocitnice"}, 
{"count":"96","search_date":"2015-11-26","search_area":"potovanja"}, 
{"count":"382","search_date":"2015-11-27","search_area":"lastni-pre"}, 
{"count":"56","search_date":"2015-11-27","search_area":"letalske"}, 
{"count":"244","search_date":"2015-11-27","search_area":"pocitnice"}, 
{"count":"77","search_date":"2015-11-27","search_area":"potovanja"}, 
{"count":"205","search_date":"2015-11-28","search_area":"lastni-pre"}, 
{"count":"40","search_date":"2015-11-28","search_area":"letalske"}, 
{"count":"303","search_date":"2015-11-28","search_area":"pocitnice"}, 
{"count":"95","search_date":"2015-11-28","search_area":"potovanja"}, 
{"count":"442","search_date":"2015-11-29","search_area":"lastni-pre"}, 
{"count":"59","search_date":"2015-11-29","search_area":"letalske"}, 
{"count":"515","search_date":"2015-11-29","search_area":"pocitnice"}, 
{"count":"83","search_date":"2015-11-29","search_area":"potovanja"}, 
{"count":"565","search_date":"2015-11-30","search_area":"lastni-pre"}, 
{"count":"125","search_date":"2015-11-30","search_area":"letalske"}, 
{"count":"550","search_date":"2015-11-30","search_area":"pocitnice"}, 
{"count":"128","search_date":"2015-11-30","search_area":"potovanja"}, 
{"count":"519","search_date":"2015-12-01","search_area":"lastni-pre"}, 
{"count":"78","search_date":"2015-12-01","search_area":"letalske"}, 
{"count":"489","search_date":"2015-12-01","search_area":"pocitnice"}, 
{"count":"101","search_date":"2015-12-01","search_area":"potovanja"}, 
{"count":"230","search_date":"2015-12-02","search_area":"lastni-pre"}, 
{"count":"56","search_date":"2015-12-02","search_area":"letalske"}, 
{"count":"244","search_date":"2015-12-02","search_area":"pocitnice"}, 
{"count":"43","search_date":"2015-12-02","search_area":"potovanja"}] 

我怎么能在JavaScript中创建对象，它应该是这样的：

[{ 
    name: 'lastni-pre', 
    data: [391, 457, ...]}, 
{ 
    name: 'letalske', 
    data: [63, 103, ...]}, 
{ 
    name: 'pocitnice', 
    data: [501, 509, ...]}, 
{ 
    name: 'potovanja', 
    data: [114, 184, ...] 
}] 

我需要这个对象highcharts基本列。

您可以使用underscore.js库来帮助您。

然后，你可以做这样的事情：

_.chain(yourItemArray) 
.groupBy('search_area') 
.map(function(value, key) { 
    return { 
     name: key, 
     data: _.pluck(value, 'count') 
    } 
}) 
.value();
