不知道如何对这个JSON对象jQuery / JavaScript进行排序

示例字符串:

var output = { 
      "myservices":[
         {"name":"oozie", "hostidn": "1", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"},
         {"name":"oozie", "hostidn": "2", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"},
         {"name":"oozie", "hostidn": "3", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"},
         {"name":"oozie", "hostidn": "4", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"},
         {"name":"oozie", "hostidn": "5", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"},
         {"name":"single-namenode", "hostidn": "2", "details":"failed process health monitor....", "currstatus":"Warning", "currstatusclass":"warning"}
]};

我的饼干杰克试图这样做。

function sortJSONresultsByHost(a,b)
{
    var objectIDA = parseInt(a.hostidn, 10)
    var objectIDB = parseInt(b.hostidn, 10)
    if(objectIDA === objectIDB)
    {
        return 0;
    }
    return objectIDA > objectIDB ? 1 : -1;
}
output.myservices.sort(sortJSONresultsByHost);

我实际上需要弄清楚如何以各种方式进行排序。例如由hostidn,名字,由currstatusclass。但我无法弄清楚最好的方法。有没有办法制作一个可以通过选择做任何事情的功能,或者我需要根据我想要做的一组功能,如果有的话?我的上面不适合我。

function sortObjectsByKey(objects, key){
    objects.sort(function() {
        return function(a, b){
            var objectIDA = a[key];
            var objectIDB = b[key];
            if (objectIDA === objectIDB) {
                return 0;
            }
            return objectIDA > objectIDB ? 1 : -1;        
        };
    }());
}

sortObjectsByKey(output.myservices, "hostidn");
console.log(output.myservices);
