访问JSON对象内的数组元素

Question

I have the following json-object returned via response

the function

 function getUserList() {

$.ajax({
    url: "https://reqres.in/api/users",
    type: "POST",
    data: {
        name: "paul rudd",
        movies: ["I Love You Man", "Role Models"]
    },
    success: function(response){

        console.log(response); // prints the object


    }
});

}

My question is how the movies-array are accessed in javascript? I cannot access it via response - if I do i get "undefined" returned.

ie response.movies

undefined

or response.movies[0]

uncaught typerror cannot read property [0] of undefined

Answer 1

Try response['movies[]'] . Also, you could console log the response object and inspect what is inside it

Answer 2

对象的属性似乎是"movies[]" ，而不是"movies" ，您可以使用方括号表示法获取其值

console.log(response["movies[]"][0])

Answer 3

in your back end you're returning with bad naming , so

to access that array you've to access it as below response.["movies[]"]

see below sample :

 response = { "movies[]": ["1","2","3"] }; console.log(response["movies[]"]); 

Answer 4

movies is array, use $.each or .forEach()

$.ajax({
  url: "https://reqres.in/api/users",
  type: "POST",
  data: {
    name: "paul rudd",
    movies: ["I Love You Man", "Role Models"]
  },
  success: function(response) {
    $.each(response.movies, function(index, value){
      // prints the object
      console.log(value);
    })
  }
});
