jQuery:识别声明变量的值与数组中键列表中的值相同

Question

我有一组 json 数组，如下所示:

{"status":200,"success":true,"result":
[{"id":"0","name":"user1","type":"mf","message":"bonjour user1"},
{"id":"1","name":"user2","type":"ff","message":"hello user2"},
{"id":"2","name":"user3","type":"mm","message":"konnichiwa user3"},
{"id":"3","name":"user4","type":"mf","message":"ni hao user4"},
{"id":"4","name":"user5","type":"ff","message":"high 5! user5"}]}

我想问如何确定已声明变量的值(例如，值为“user1”的“getName”)与数组中“name”键列表中的值是否相同？

下面是我的尝试，您可能会找到我的完整代码 here :

var apiUrl = "https://sheetsu.com/apis/f924526c"; 

$.getJSON(apiUrl,function(json){

    console.log(JSON.stringify(json));

        var getName = $.each(getName, function(content, json){
            console.log(json.name);
            console.log(getName[content].id);
        });

        var identifiedId = $.each(getName, function(){
            console.log(this.name);
            console.log(this.id);
        })
});

Answer 1

我不确定我是否理解您的代码，但为了循环 json 并找到您想要使用的键值:

$.each(json.result, function() {
     //here you can store id.
     $.each(this, function(key, value) {
        console.log(key + ' ' + value);
        //test if key  = username you want and store value
     });
});

您也可以通过一个循环来完成此操作，因为您知道要检查哪个键

$.each(json.result, function() {
    if (this.name == "name you look for"){
        idyouneed = this.id;
    }
}
