问题:

The example is here http://jsfiddle.net/V3qb9/57/. It runs perfectly on desktop and jsfiddle -- whenever I change the radio button, an alert is popped up. But when I try it on phonegap, the click event is not triggered at all. Any thoughts why?

回答1:

i tried your code in the init method used by phonegap in body onload tag <body onload="init();"> and i was able to see the alert.

i used the example that comes with phonegap 1.9.0 for android.

i tested it on my phone (Jelly Bean).

Are you correctly binding the the action on Device ready? I don't think $(document) works in Phonegap the way it does in a browser. According to this answer:

The relationship between Phonegap's "onBodyLoad()/onDeviceReady()" functions and Jquery's "$(document).ready()"

try this instead:

window.addEventListener('load', function () {
    document.addEventListener('deviceready', function () {
        alert("PhoneGap is now loaded!");
    }, false);
}, false);

use

/* enter code here */ function onBodyLoad()
{       
    document.addEventListener("deviceready", onDeviceReady, false);
}function onDeviceReady()
{
    // do your thing!
    //navigator.notification.alert("Cordova is working")
}

top of your script. Hope it will work
