PhoneGap（Cordova.js）和JQuery.Ajax不能在一起工作 [英] PhoneGap (Cordova.js) and JQuery.Ajax not working together
问题描述
我已经建立了一个html页面使用Phonegap + Jquery定位Andriod 4.12。
I have built a html page using Phonegap+Jquery targeting Andriod 4.12.
我的业务要求是使用cameraova.js的相机API拍摄照片，然后将此捕获的图片发送到ASMX Web服务。
My business requirement is to take a picture using the camera API of cordova.js and then post this captured picture to a ASMX web service.
问题：当我添加对Cordova.js的引用并运行应用程序时，我在LogCatUncaught ReferenceError ：$未定义，但如果我删除对cordova.js的引用一切正常，我可以发布数据到Web服务。
Problem : When I add a reference to Cordova.js and run the application I get an error in the LogCat "Uncaught ReferenceError: $ is not defined" but if i remove the reference to cordova.js everything works fine and i am able to post data to web service.
我附加我的代码
<!DOCTYPE html>
<html>
<head>
<title>Capture Photo</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.1.0.js"></script>
<script type="text/javascript" charset="utf-8" src="jquery.js"></script>
<script type="text/javascript">
var varType;
var varUrl;
var varData;
var varContentType;
var varDataType;
var varProcessData;
function InsertDetails() {
alert('Inserting Details');
varType = "POST";
varUrl = "http://mobile.comp.com/service/userservice.asmx/InsertDetails";
varContentType = "application/json; charset=utf-8";
varDataType = "json";
varProcessData = true;
var uname = document.getElementById('txtname');
var pwd = document.getElementById('txtpwd');
CallService(uname.value, pwd.value);
return true;
}
//Generic function to call AXMX/WCF Service
function CallService(u, p) {
$.ajax({ type: varType, url: varUrl, data: '{"username":"' + u + '","password":"' + p + '"}', contentType: varContentType, dataType: varDataType, processdata: varProcessData, success: function (msg) { ServiceSucceeded(msg); }, error: ServiceFailed });
}
function ServiceSucceeded(result) {
var myObject = eval('(' + result.d + ')');
alert(myObject);
}
function ServiceFailed(result) {
alert('Service call failed: ' + result.status + '' + result.statusText);
varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null;
}
</script>
</head>
<body>
<input type=text id=txtname value=John />
<input type=text id=txtpwd value=Doe />
<input type="button" id="btnSearch" onclick="InsertDetails();" style="cursor: pointer;
margin-top: 8px; vertical-align: top" value="Insert Details" />
<button id=btn1>Capture Photo</button>
</body>
</html>
请帮助我。
推荐答案
感谢Nick的帮助。第三个链接帮助了
Thanks Nick for your help. The 3rd link helped
最后我的代码工作了
我添加了以下代码行
jQuery.noConflict();
之后，JQuery被识别。
JQuery was recognised after that. Make sure to follow the proper sequence for javascripts else the code will not work.
我引用js文件的顺序：
The sequence in which I referred the js files:
- 参考JQuery.js（本地添加到项目中）
- jQuery.noConflict（）;
-
-
- 参考Cordova.js
- Cordova摄影机互动代码
- Reference to JQuery.js (locally added to project)
- jQuery.noConflict();
- Javascript Code for service calls
- Reference to Cordova.js
- Cordova Camera interaction code
