javascript - 获取 JSON 对象数组中的值

Question

我有一个 JSON 对象数组，如下所示:

[
    { name: "tom", text: "tasty" },
    { name: "tom", text: "tasty" },
    { name: "tom", text: "tasty" },
    { name: "tom", text: "tasty" },
    { name: "tom", text: "tasty" }
]

我想循环它们并在列表中回显它们。我该怎么做？

Answer 1

你的意思是这样的吗？

 var a = [
     { name: "tom", text: "tasty" },
     { name: "tom", text: "tasty" },
     { name: "tom", text: "tasty" },
     { name: "tom", text: "tasty" },
     { name: "tom", text: "tasty" }
 ];

 function iter() {
     for(var i = 0; i < a.length; ++i) {
         var json = a[i];
         for(var prop in json) {
              alert(json[prop]);
                          // or myArray.push(json[prop]) or whatever you want
         }
     }
 }
