我想知道当我们通过javascript点击win phone 7后退按钮时我们如何执行事件..
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
document.addEventListener("backbutton", onBackKeyDown, false);
}
function onBackKeyDown() {
//want to redirect a particular page.?? want to handle functioning of back button
}
尝试以下操作：
<!DOCTYPE html>
<html>
<head>
<title>gaurish's Cordova Back Button Example</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Call onDeviceReady when Cordova is loaded.
//
// At this point, the document has loaded but cordova-2.0.0.js has not.
// When Cordova is loaded and talking with the native device,
// it will call the event `deviceready`.
//
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// Cordova is loaded and it is now safe to call Cordova methods
//
function onDeviceReady() {
// Register the event listener
document.addEventListener("backbutton", onBackKeyDown, false);
}
// Handle the back button
//
function onBackKeyDown() {
}
</script>
</head>
<body onload="onLoad()">
</body>
</html>
现在，来测试一下
添加一些onBackKeyDown()您想要运行的代码，例如
function onBackKeyDown() {
currentId = $.mobile.activePage.attr('id');
if(currentId == "#swipediv"){
$.mobile.changePage("#home", "slide", false, true);
}
else{
history.go(-1);
}
}
加载cordova-2.0.0.js
如果这仍然不起作用，请提交错误报告。
