如何将js的数组转化为json对象？

[SheldorWsy]

Array [ "PRD_NBR:CR026601,CR026101", "crl_sts:USED,APRJ,ENDC,PAUS,CLER", "BAL_YER:0,0,0", "BAL_MON:0,0,0" ]

如上面所示，现在有一个这样的数组，我想把它转换成
｛
PRD_NBR: ["CR026601" ,"CR026101"],
crl_sts:["USED","APRJ","ENDC","PAUS","CLER"],
｝
这样的形式。但是我接触js技术还不太久，不知道有没有什么好办法来动态设置JSON对象的key和value。
还请懂技术的大牛给解答解答，多谢！

  var arr=[ "PRD_NBR:CR026601,CR026101", "crl_sts:USED,APRJ,ENDC,PAUS,CLER", "BAL_YER:0,0,0", "BAL_MON:0,0,0" ],data={}
    for (var i = 0; i < arr.length; i++) { var item = arr[i].split(':'); data[item[0]] = item[1].split(',') }
    console.log(data)

var arr = [ "PRD_NBR:CR026601,CR026101", "crl_sts:USED,APRJ,ENDC,PAUS,CLER", "BAL_YER:0,0,0", "BAL_MON:0,0,0" ];
var obj = {};
for (var i = 0; i < arr.length; i++) {
	var kv = arr[i].split(":");
	obj[kv[0]] = kv[1].split(",");
}
var json = JSON.stringify(obj,null,4);
alert(json);

    var obj=arr.reduce(function(a,b){

        a[arr[0]]=arr[1].split(',');
        return a;
    },{});
