Phonegap AJAX表单不起作用

[英]Phonegap ajax form not working

我的index.html中包含以下html / javascript

<html>
<head>
    <meta charset="utf-8" />
    <meta name="format-detection" content="telephone=no" />
    <meta name="msapplication-tap-highlight" content="no" />
    <!-- WARNING: for iOS 7, remove the width=device-width and height=device-height attributes. See https://issues.apache.org/jira/browse/CB-4323 -->
    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
    <link rel="stylesheet" type="text/css" href="css/index.css" />
    <title>Hello World</title>
    <script type="text/javascript">
        function PostData() {
            // 1. Create XHR instance - Start
            var xhr;
            if (window.XMLHttpRequest) {
            xhr = new XMLHttpRequest();
            }
            else if (window.ActiveXObject) {
            xhr = new ActiveXObject("Msxml2.XMLHTTP");
            }
            else {
            throw new Error("Ajax is not supported by this browser");
            }
            // 1. Create XHR instance - End

            // 2. Define what to do when XHR feed you the response from the server - Start
            xhr.onreadystatechange = function () {
              if (xhr.readyState === 4) {
                if (xhr.status == 200 && xhr.status < 300) {
                document.getElementById('div1').innerHTML = xhr.responseText;
                }
            }
            }
            // 2. Define what to do when XHR feed you the response from the server - Start

            var userid = document.getElementById("userid").value;

            // 3. Specify your action, location and Send to the server - Start
            xhr.open('POST', 'localhost:3000/ajax');
            xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
            xhr.send("userid=" + userid);
            // 3. Specify your action, location and Send to the server - End
        };
    </script>
</head>
<body>


    <div class="app">

        <h1>Ajax Testarea</h1>

            <form>
                  <label for="userid">User ID :</label>
                  <input type="text" name ="userid" id="userid" />
                  <div id="div1"></div>
                  <input type="button" value ="Check" onclick="PostData()" />
            </form>
    </div>



    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
    <script type="text/javascript">
        app.initialize();
    </script>
</body>

这在我的Mac上运行正常,但是当我尝试使其与phonegap配合使用时,我无法单击按钮来发送表格。 因此,它将不会启动PostData()函数。

我也不确定将Javascript直接放在html内是否是个好习惯,还是将它放在index.js内更好? 我读过有关将其放入其中的信息:

onDeviceReady: function() {
        app.receivedEvent('deviceready');
   // ---My Code--- 
},

如果有人可以指出我做错了事,我将非常高兴!

我在iOS版Phonegap中使用onClick和Jquery的Click函数时遇到了问题。 我不得不将jQuery .On()函数与touchstart一起使用

$('#buttonID').on({ 'touchstart' : function(){ /* Do stuff... */ } });

看起来您使用的不是jQuery,因此可以尝试使用onTouch="function"onTouchStart="function"代替onClick。
