javascript - 如何将具有相同键的对象数组分组为单个数组中的对象？

Question

我的数组是

[Object { Color="Blues",  Shape="Octagon",  Thickness="High (Over 1 Inch)",  more...}, Object { Color="Burgundys",  Shape="Oval",  Thickness="3⁄8" (approx.)",  more...}]

我想要输出:

[{"Color":["Blues","Burgundys "],"Shape":['Octagon',"Oval"]}] 

其他值也一样

Answer 1

我会通过迭代每个对象的键并将键作为哈希添加到值对象中来解决此问题。

var vals = {}
var src = [{ Color="Blues",  Shape="Octagon",  Thickness="High (Over 1 Inch)"}, { Color="Burgundys",  Shape="Oval",  Thickness="3⁄8 (approx.)"}]

src.forEach( function( obj ){

    for( var key in obj ){
        if( vals[ key ] === undefined ) 
            vals[ key ] = []

        vals[ key ].push( obj[ key ])
    }

})
