如何找到特定的对象，并将它们放入JavaScript中的数组中 [英] how to find specific objects and put them in an array in javascript

问题描述

我的脚本中有这个结果

 '[{region：NCA，depprt：古巴哈瓦那，{区域：NCA，depprt：古巴哈瓦那}，{区域：NCA，depprt：牙买加蒙特哥湾}， ：NCA，depprt：牙买加蒙特哥贝}]'
  

$ b

  var jsonList ='@ Html.Raw（Json.Encode（ViewBag.chk））'
 var jsList = JSON.stringify（jsonList）; 
  

代表 jsList 我想获得所有 depprt ，其中 region 等于 NCA .how能否做到这一点。

com / jsref / jsref_filter.asprel =nofollow> .filter（）方法。

  var ncaList = jsonList.filter（function（obj）{return obj.region ==NCA;}）; 
  

I have this result in my script

'[{"region":"NCA","depprt":"Havana, Cuba"},{"region":"NCA","depprt":"Havana, Cuba"},{"region":"NCA","depprt":"Montego Bay, Jamaica"},{"region":"NCA","depprt":"Montego Bay, Jamaica"}]'

this is the code to get it.

var jsonList = '@Html.Raw(Json.Encode(ViewBag.chk))'
        var jsList = JSON.stringify(jsonList);

for jsList I got above result.now I want to get all depprt where region is equal to NCA.how can I do that.

解决方案

You can use the .filter() method for this.

var ncaList = jsonList.filter(function(obj){ return obj.region == "NCA"; });
