Question

我需要发布数据并显示它。我正在使用ajax post方法。我能够获取保存数据的事件ID，但无法显示数据。我搜索了很多，也得到了一些答案。我在我的代码中尝试过，但没有得到结果。我的代码是：

<!DOCTYPE html>
<html>

    <head>
        <title>POST API</title>
        <script type="text/javascript" src="http://ajax.googleapis.com      /ajax/libs    /jquery/1.2.6/jquery.js"></script>
    </head>

    <body>
        <button id="btn1">Check HTTP POST</button>
        <p>Display sample output from POST API:</p>
        <p id="one" />wEventId :
        <p id="two" />
        <script>
            $(document).ready(function() {
                $("#btn1").click(function() {
                    $.ajax({
                        url: 'url',
                        dataType: 'json',
                        type: 'POST',
                        crossDomain: true,
                        contentType: 'application/json',
                        data: {},
                        success: function(data) {
                            console.log(data);
                            document.getElementById("two").innerHTML = data.result.wEventId;
                        },
                        failure: function(errMsg) {
                            console.log(errMsg);
                        }
                        var myData = data;
                        myData = new Array;

                    });
                });
            });
        </script>
    </body>

</html>

任何人都可以帮我修改代码以打印保存的数据。我没有给出网址，因为它是一个内部服务器，并且不应该透露它。提前谢谢。

Answer 1

首先我需要知道你的json数据的结构是什么。

假设它的格式如下：

{"field_A":"value_a","field_b":"value_b"}

您尝试打印的代码，因为innerHTML应该是这样的：

success: function(data)
{
   console.log(data); 
   document.getElementById("two").innerHTML =     data.field_A;
},

尝试相应调整。

我仍然对你在result data.result.wEventId

的
