Php JavaScript按和排序JSON

我们得到的是一个JSON字符串，如下所示：

[{"id":"1499","tradingname":"Golden Shutter Photography","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"500|50","tstamp":"2012-01-26 19:26:24","offers":"500|50"}]

我们需要的是一种JavaScript方式来对结果进行排序/洗牌，这样他们就可以接受报价并将其排序，最后显示出最大的差异，而第一个显示的差异较小

例如，假设JSON中的提供如下

100|10

100|20

100|9

它将把它按顺序排列

100|20

100|10

100|9

现在的问题是，一些报价的报价超过了1个报价，因此它们如下所示

100|20,100|9,100|10

在这种情况下，我们也要将100 | 9移动到末端，如下所示

100|20,100|10,100|9

这应该给你一个想法。但是在调用json_encode之前，在php中使用multisort对数组进行排序会更有效

 var arr = [
      {"id":"1498","tradingname":"Golden Shutter Photography1","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"200|60","tstamp":"2012-01-26 19:26:24","offers":"200|40"},
      {"id":"1499","tradingname":"Golden Shutter Photography2","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"400|50","tstamp":"2012-01-26 19:26:24","offers":"200|50"},
      {"id":"1500","tradingname":"Golden Shutter Photography3","listed":"2012-01-26 19:26:24","pictureurl":"","business_id":"1499","storeid":"1","phone":"6143737477","street":"122 Avebery Drive","suburb":"Berwick ","state":"1","postcode":"3806","discription":"","long":"","lat":"","offer":"200|50","tstamp":"2012-01-26 19:26:24","offers":"400|50"}
    ];


    function sortbyoffer(a,b) {
      var aa = a.offer.split("|");
      var bb = b.offer.split("|");
      if(aa[0] == bb[0]) {
        return aa[1] - bb[1];
      } else {
        return aa[0] - bb[0]; 
      }
    }

    arr.sort(sortbyoffer);

    for(var n=0;n<arr.length;n++){
      document.write(arr[n].id + ' ' + arr[n].tradingname +  ' ' + arr[n].offer + '<br>');
    }

@rdlowrey我尝试在MySQL点对其排序，并使用jquery.sortwhy用javascript对排序？在使用json_encode之前，在php中使用multisort对数组进行排序。

1500 Golden Shutter Photography3 200|50
1498 Golden Shutter Photography1 200|60
1499 Golden Shutter Photography2 400|50
