我有以下JSON结构:
[{ "id":"10", "class": "child-of-9" }, { "id": "11", "classd": "child-of-10" }]
我如何使用JavaScript迭代它?

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));
});
mootools的例子:
var ret = JSON.decode(jsonstr);
ret.each(function(item){
alert(item.id+'_'+item.classd);
});
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>

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]);
}
