Question

我们希望使用javascript将json文件中的所有名称显示为div。我们尝试了很多东西，但我们没有成功。

json数据：http://www.smartbustracking.be/json/data.json

这是我们尝试过的：

<button>get data</button>
<div id="resultJson"></div>


<script type="text/javascript" language="javascript">
             $("button").click(function(){
                    $.getJSON("http://www.smartbustracking.be/json/data.json", function(result){
                        for(var x = 0; x < result.length; x++){

                                $.each(result, function(i, field) {
                                    $("#resultJson").append(field[x].name);
                                }

                        }
                    });
            });

如果有人可以帮助我们解决这个问题，那就太棒了

提前致谢！

Answer 1

不要在for循环中使用额外的循环来提取名称。

您的数据就像

[0] = {name:"name1"}
[1] = { name: "name2"}

如果[0]中有一个数组并且你想从中提取值，那么你需要在for循环内部另外一个循环来提取该值，就像你想要提取bushaltes的值一样。

试试这个

$("button").click(function() {
    $.getJSON("http://www.smartbustracking.be/json/data.json", function(result) {
        console.log(result);
        for (var x = 0; x < result.length; x++) {
            $("#resultJson").append(result[x].name);
        }
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>get data</button>
<div id="resultJson"></div>

Answer 2

您需要 for循环或 $.each，而不是两者。

这是更新的代码。

 $("button").click(function(){
        $.getJSON("http://www.smartbustracking.be/json/data.json", function(result){
            $.each(result, function(i, field) {
                $("#resultJson").append(field.name);
            });
        });
   });

这里是demo

另外，我认为您应该使用for代替result[x].name，因为您将field[x].name作为回调函数的参数：

result

使用ajax显示来自url的JSON数据
