添加到javascript关联数组

Question

我想要以下结构:

    var data={"users":[
    {
        "firstName":"Ray",
        "lastName":"Villalobos",
        "joined":2012
    },
    {
        "firstName":"John",
        "lastName":"Jones",
        "joined":2010
    }
    ]}

我希望能够以编程方式添加条目.这是我尝试过的:

  var data = [];
   data.push({
     "firstName":"Johsssn",
     "lastName":"Jossnes",
     "joined":2010
   });

Answer 1

你的阵列实际上data.users不是data.
所以请改用:

var data = {users: []};
data.users.push({
  "firstName":"Johsssn",
  "lastName":"Jossnes",
  "joined":2010
});
