我正在研究我的Android手机PhoneGap应用程序（我使用的是Android 2.3模拟器），并且我解决了一些问题。
我的项目有两页：index.html＆amp; page.html中。
我使用
从index.html导航到page.htmlself.location="page.html"+'?'+textAImp+"&12";
此代码位于我的“js / index.js”[创建项目时创建的默认文件]。
它工作正常，它让我到我的“page.html”，但当我尝试使用“js / index.js”中包含的相同功能时（我在2页中使用相同的js函数），它只是不在我的第二页上工作！
adb logcat给了我这个：
D/CordovaLog( 598): file:///android_asset/www/phonegap.js: Line 1548 : Could not find cordova.js script tag. Plugin loading may fail.
I/Web Console( 598): Could not find cordova.js script tag. Plugin loading may fail. at file:///android_asset/www/phonegap.js:1548
D/CordovaLog( 598): file:///android_asset/www/js/index.js: Line 128 : ReferenceError: Can't find variable: Connection
E/Web Console( 598): ReferenceError: Can't find variable: Connection at file:///android_asset/www/js/index.js:128

D/CordovaActivity( 598): onMessage(onPageFinished,file:///android_asset/www/page.html?20.09724882&12)
我对此感到困惑，因为它在我的“index.html”
中工作正常我将我的网页代码和phonegap.js代码放在下面：
“的index.html”

感谢您的帮助:)。

我不确定，但你可以尝试代替window.onload这个
<script type="text/javascript">
$(document).ready(init);
function init() {
document.addEventListener("deviceready", deviceInfo, true);
}
function onDeviceReady() {
var a = self.location.href.split('?')[1].split('&');
document.getElementById("parag").innerHTML=a[0]<br>" + a[1];
alert('Query string: '+self.location.search);
jsfunction() ;
}
</script>
