json相关操作

1.json对象转换为数组

var fields={
   "CeShi": "测试",
   "CheXingYaoQiu": "车型要求",
   "ChengCheRenShu": "乘车人数",
   "ChuFaDiDian": "出发地点",
   "ErJiShenPi": "二级审批",
   "FeiYongChengDan": "费用承担",
   "LianXiDianHua": "联系电话"
   
  }
  //转换为[{},{},{}]形式
  var sx=[];
  Object.keys(fields).forEach(v => {
   let o = {};
   o[v] = fields[v];
   sx.push(o)
  })
  alert(JSON.stringify(sx))
//输出结果
//[{"CeShi":"测试"},{"CheXingYaoQiu":"车型要求"},{"ChengCheRenShu":"乘车人数"},{"ChuFaDiDian":"出发地点"},{"ErJiShenPi":"二级审批"},{"FeiYongChengDan":"费用承担"},{"LianXiDianHua":"联系电话"}]

2.json数组删除某个值

var  s = [{"name":"tank","total":"100"},{"name":"zhang","total":"23"},{"name":"hao","total":"325"}];
for(var k=0;k<s.length;k++){
    delete s[k]["name"];
    }
alert(JSON.stringify(s))
//输出结果
//[{"total":"100"},{"total":"23"},{"total":"325"}]
