javascript - 我如何从这个json字符串读取数据？

[
   {
      "Intent":"what is manufacturer name?",
      "Entity":"Name",
      "Response":"Test",
      "Status":"0",
      "Created_Date":"2017-04-04T00:00:00",
      "Response_Count":0,
      "Response_Count_string":0
   },
   {
      "Intent":"hi",
      "Entity":"hi",
      "Response":"hiiii",
      "Status":"0",
      "Created_Date":"2017-03-28T10:22:00",
      "Response_Count":0,
      "Response_Count_string":0
   },
   {
      "Intent":"how are you?",
      "Entity":"are you fine",
      "Response":"good!cool",
      "Status":"1",
      "Created_Date":"2017-03-28T10:22:38",
      "Response_Count":0,
      "Response_Count_string":0
   }
]

最佳答案

从JSON String读取数据的方式：

1.使用Javascript

var jsonStr = "[{\"Intent\":\"what is manufacturer name?\",\"Entity\":\"Name\",\"Response\":\"Test\",\"Status\":\"0\",\"Created_Date\":\"2017-04-04T00:00:00\",\"Response_Count\":0,\"Response_Count_string\":0},{\"Intent\":\"hi\",\"Entity\":\"hi\",\"Response\":\"hiiii\",\"Status\":\"0\",\"Created_Date\":\"2017-03-28T10:22:00\",\"Response_Count\":0,\"Response_Count_string\":0},{\"Intent\":\"how are you?\",\"Entity\":\"are you fine\",\"Response\":\"good!cool\",\"Status\":\"1\",\"Created_Date\":\"2017-03-28T10:22:38\",\"Response_Count\":0,\"Response_Count_string\":0}]";

var jsonObj = JSON.parse(jsonStr);

for (var i in jsonObj) {
  console.log(jsonObj[i].Intent);
}

2.使用AngularJS

var myApp = angular.module('myApp',[]);

myApp.controller('MyCtrl',function($scope) {
    var jsonStr = "[{\"Intent\":\"what is manufacturer name?\",\"Entity\":\"Name\",\"Response\":\"Test\",\"Status\":\"0\",\"Created_Date\":\"2017-04-04T00:00:00\",\"Response_Count\":0,\"Response_Count_string\":0},{\"Intent\":\"hi\",\"Entity\":\"hi\",\"Response\":\"hiiii\",\"Status\":\"0\",\"Created_Date\":\"2017-03-28T10:22:00\",\"Response_Count\":0,\"Response_Count_string\":0},{\"Intent\":\"how are you?\",\"Entity\":\"are you fine\",\"Response\":\"good!cool\",\"Status\":\"1\",\"Created_Date\":\"2017-03-28T10:22:38\",\"Response_Count\":0,\"Response_Count_string\":0}]";

    $scope.jsonObj = JSON.parse(jsonStr);
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
  <div ng-repeat="item in jsonObj">
    {{item.Intent}}
  </div>
</div>
