如果不容易，请告诉我:

var jsonObject = {
  name: 'Amit Kumar',
  Age: '27'
};

for (var prop in jsonObject) {
  alert("Key:" + prop);
  alert("Value:" + jsonObject[prop]);
}

从http://www.w3schools.com复制和粘贴，不需要JQuery开销。

var person = {fname:"John", lname:"Doe", age:25};

var text = "";
var x;
for (x in person) {
    text += person[x];
}

结果:无名氏25人

取自jQuery文档:

var arr = [ "one", "two", "three", "four", "five" ];
var obj = { one:1, two:2, three:3, four:4, five:5 };

jQuery.each(arr, function() {
  $("#" + this).text("My id is " + this + ".");
  return (this != "four"); // will stop running to skip "five"
});

jQuery.each(obj, function(i, val) {
  $("#" + i).append(document.createTextNode(" - " + val));
});

使用的…:

var mycars = [{name：'Susita'}， {name：'BMW'}]; 对于（MyCars的VaR Car） { document.write（car.name + “<br />”）; }

结果:

Susita
BMW

对于嵌套对象，可以通过递归函数检索:

function inside(events)
  {
    for (i in events) {
      if (typeof events[i] === 'object')
        inside(events[i]);
      else
      alert(events[i]);
    }
  }
  inside(events);

其中as events是json object。

var jsonString = `{ "schema": { "title": "User Feedback", "description": "so", "type": "object", "properties": { "name": { "type": "string" } } }, "options": { "form": { "attributes": {}, "buttons": { "submit": { "title": "It", "click": "function(){alert('hello');}" } } } } }`; var jsonData = JSON.parse(jsonString); function Iterate(data) { jQuery.each(data, function (index, value) { if (typeof value == 'object') { alert("Object " + index); Iterate(value); } else { alert(index + " : " + value); } }); } Iterate(jsonData); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
