Hai i am new in phonegap and ratchet framework.I am trying to load external script with push.js. Here is my js file contents
function init(){
document.addEventListener('deviceready', onDeviceReady, false);
function onDeviceReady(){
alert("device ready for use");
}
var checkPage = function(){
alert("push");
var scriptName;
var scriptsList = document.querySelectorAll('script.js-custom'); // Add a "js-custom" class to your script tag
for (var i = 0; i<scriptsList.length;i++) {
// Handle scripts in separate files by assigning the script file name to its id.
// We save it in a variable because the ".done" callback is asynchronous.
scriptName = scriptsList[i].id; // IMPORTANT: Only one loadable script per page!
$.getScript("js/" + scriptName)
.done(function (script, textStatus) {
eval(script);
alert("ok");
})
.fail(function(){
alert("error");
});
}
};
window.addEventListener('push', checkPage);
}

Reset to default 8It's because window.CustomEvent is missing in you WebView implementation.
Add this Polyfill and it works every times. I found the solution on Mozilla Developer Network:
/*
* Polyfill for adding CustomEvent
* see : https://developer.mozilla/fr/docs/Web/API/CustomEvent
*/
if (!window.CustomEvent) { // Create only if it doesn't exist
(function () {
function CustomEvent ( event, params ) {
params = params || { bubbles: false, cancelable: false, detail: undefined };
var evt = document.createEvent( 'CustomEvent' );
evt.initCustomEvent( event, params.bubbles, params.cancelable, params.detail );
return evt;
};
CustomEvent.prototype = window.Event.prototype;
window.CustomEvent = CustomEvent;
})();
}
You do not have cordova in your second html file. When you load two.html, your browser destroys the previous page and all the scripts associated with it. You should do everything in single page, I suggest using an mvvm framework such as angularjs, emberjs etc.
So, to be exact, your second html does not have cordova, so deviceready is never fired for that file. However, for the first html, you have deviceready and ratchet references. But, in there, you don't have your sample.js reference with js-custom. So, inside deviceready (when in first html), your ratchet is plaining about missing js-custom reference.
