API中的JSON格式错误

Question

I'm currently using an API and getting the following results for my GET request:

[{"id" : 123456, "title" : "hello world", "post" : "this is the actually text of the    blog"}, {"id" : 123457, "title" : "hello world 2", "post" : "this is the second blog post"}]

I want to be able to get each title & post, but my basic knowledge of JSON would tell me that I need to declare each part of the array, like this:

["data" : {"id" : 123456, "title" : "hello world", "post" : "this is the actually text of the    blog"}, "data" : {"id" : 123457, "title" : "hello world 2", "post" : "this is the second blog post"}]

Does anyone have any ideas as to how I can iterate through this into HTML?

Thanks.

Answer 1

The first one is an array containing two objects, the second is an array with a named object, containig two child objects. Your second example won't work, because you're assigning array elements names (data, post) while arrays are auto-indexed with integers. The syntax is simply invalid.

Using the result you get from the API, you first need to convert it into an object.

resultObject = JSON.parse('[{"id" : 123456, "title" : "hello world", "post" : "this is the actually text of the    blog"}, {"id" : 123457, "title" : "hello world 2", "post" : "this is the second blog post"}]');

After this, you can simply iterate over the array:

resultObject.forEach(function(e) {
    console.log(e.title + ": " + e.post);
});

The above will output

hello world: this is the actually text of the    blog
hello world 2: this is the second blog post

Answer 2

Here is a working jsfiddle of the solution at http://jsfiddle.net/4WxFk/3/

        <div id="response"></div>
<script>
        var res= '[{"id" : "123456", "title" : "hello world", "post" : "this is the actually text of the blog"}, {"id" : "123457", "title" : "hello world 2", "post" : "this is the second blog post"}]'

        var pres = JSON.parse(res)
        $.each(pres, function(){
            console.log(this)
        $("#response").append(this.id + ","+ this.title + "," + this.post)
        })
</script>
