Javascript多维数组：添加值

所以我有一个多维数组，如：

myArr = [["venue",2],["venue",16],["inning",2],["inning",4],["inning",32],["hithard", 4]]

我想添加类似的值。所以最后我只有：

 "venue" = 18, "inning" = 38, and "hithard" = 4.

你能给我一个如何实现这个目标的例子吗？使用Javascript和/或jQuery

谢谢！

我不确定你是否想要一个数组或对象。如果是object，则停止它是第一遍并且下面代码中的tmp应该返回对象作为Object { venue=18, inning=38, hithard=4} 。

DEMO

 var tmp = {}, keys; for (var i = 0; i < myArr.length; i++) { keys = myArr[i][0]; tmp[keys] = (tmp.hasOwnProperty(keys))? (tmp[keys] + myArr[i][1]):myArr[i][1]; } //tmp - will return you a Object { venue=18, inning=38, hithard=4} var output = []; for (keys in tmp) { output.push([keys, tmp[keys]]); } //output will return you an array as [["venue", 18],["inning", 38],["hithard", 4]]

 myArr = [["venue",2],["venue",16],["inning",2],["inning",4],["inning",32],["hithard", 4]]; values = {}; for (i=0;i
