Question

我有两个具有层次结构的对象JSON。我需要在JSON中比较rowset中的每个对象。而且价值没有得到平等的地方然后我必须在相应的对象上添加一个标志。

请看看我的JSON并为此提供解决方案。如果不是角度至少我必须在Javascript中实现。

提前致谢...

JSON1

{"entityinfo":{"entity":"Customer29Jan16","tenantid":"292FEC76-5F1C-486F-85A5-09D88096F098","timestamp":"2015-12-15T10:16:06.322Z"},"collections":{"Customer29Jan16":{"rowset":[{"CuId":"123","Name":"Ranjini","Quantity":"60","Rate":"60","Amount":"3600"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]},"Customer29Jan16Obj":{"rowset":[{"CuObjId":"456","FullAddress":"Electronic City","ObjAddr":"Bangalore","ObjName":"Testing"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]}}}

JSON2

{"entityinfo":{"entity":"Customer29Jan16","tenantid":"292FEC76-5F1C-486F-85A5-09D88096F098","timestamp":"2015-12-15T10:16:06.322Z"},"collections":{"Customer29Jan16":{"rowset":[{"CuId":"123","Name":"Vijay","Quantity":"60","Rate":"60","Amount":"3600"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]},"Customer29Jan16Obj":{"rowset":[{"CuObjId":"456","FullAddress":"SilkBoard","ObjAddr":"Bangalore","ObjName":"Testing"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]}}}

Answer 1

使用angular.equals(o1,o2)。它进行深度比较，不依赖于键的顺序

angular.equals(JSON1, JSON2); // return boolean (true or false) based on the comparison

参考：Angularjs Docs

Answer 2

我已经为你建立了一个开始的例子。你可以玩它here。

的JavaScript

var json1 = {"entityinfo":{"entity":"Customer29Jan16","tenantid":"292FEC76-5F1C-486F-85A5-09D88096F098","timestamp":"2015-12-15T10:16:06.322Z"},"collections":{"Customer29Jan16":{"rowset":[{"CuId":"123","Name":"Ranjini","Quantity":"60","Rate":"60","Amount":"3600"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]},"Customer29Jan16Obj":{"rowset":[{"CuObjId":"456","FullAddress":"Electronic City","ObjAddr":"Bangalore","ObjName":"Testing"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]}}};

var json2 = {"entityinfo":{"entity":"Customer29Jan16","tenantid":"292FEC76-5F1C-486F-85A5-09D88096F098","timestamp":"2015-12-15T10:16:06.322Z"},"collections":{"Customer29Jan16":{"rowset":[{"CuId":"123","Name":"Vijay","Quantity":"60","Rate":"60","Amount":"3600"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]},"Customer29Jan16Obj":{"rowset":[{"CuObjId":"456","FullAddress":"SilkBoard","ObjAddr":"Bangalore","ObjName":"Testing"}],"meta":{"parentreference":"***","pkname":"***","fkname":"***"},"rowfilter":[]}}};

function compareJSON(json1, json2) {
  var objectsDiffering = [];
  compareJSONRecursive(json1, json2, objectsDiffering);
  return objectsDiffering;
}

function compareJSONRecursive(json1, json2, objectsDiffering) {
  for(prop in json1) {
    if(json2.hasOwnProperty(prop)) {
        switch(typeof(json1[prop])) {
        case "object":
            compareJSONRecursive(json1[prop], json2[prop], objectsDiffering);
          break;
        default:
          if(json1[prop] !== json2[prop]) {
            objectsDiffering.push(json1);
          }
          break;
      }
    } 
    else {
      objectsDiffering.push(json1);
      break;
    }
  }
}

var differing = compareJSON(json1, json2);
console.log(JSON.stringify(differing));
//Logs: [{"CuId":"123","Name":"Ranjini","Quantity":"60","Rate":"60","Amount":"3600"},{"CuObjId":"456","FullAddress":"Electronic City","ObjAddr":"Bangalore","ObjName":"Testing"}]

如何使用AngularJs比较两个对象JSON？
