有一个内置的parseJSON jQuery 中的函数。

编辑:使用示例:

// make a reference
var Obj = $.parseJSON('the json object');

alert(Obj.response.docs[0].c_application_number);  

如何？

As you descend into the nodes, the name of the node goes on, so for example if you have a JSON object like this:

{
    "parent": {
        "sibling": "you found a sibling",
        "child": {
            "more_children": "hello"
        }
    }
}

使用这样的代码:

var json = $.parseJSON('{ "parent": { "sibling": "you found a sibling", "child": { "more_children": "hello" } } }');

// I want to get the sibling value
alert(json.parent.sibling);

// I want to get the children value
alert(json.parent.child.more_children);
