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" }
]

我想循环遍历它们并在列表中回显它们。我该怎么办？

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
         }
     }
 }

Answer 2

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

for(var i in json){
    var json2 = json[i];
    for(var j in json2){
        console.log(i+'-'+j+" : "+json2[j]);
    }
}
