我最終通過構建自定義加載程序來解決這個問題。我不確定是否有更多Sencha-ish的方式來做到這一點，但這裏是我所做的細節，哪些是有效的，以防其他人想要確保PhoneGap完全被加載到包中，並且生成之前生成在Sencha運行任何東西。 （在PhoneGap打包Sencha應用程序的所有情況下，情況可能如此）。
我的index.html文件：
<!DOCTYPE HTML>
<html manifest="" lang="en-US">
<head>
<!-- Load Cordova first. Replace with whatever version you are using -->
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
function onBodyLoad() {
// Check for whatever mobile you will run your PhoneGap app
// on. Below is a list of iOS devices. If you have a ton of
// devices, you can probably do this more elegantly.
// The goal here is to only listen to the onDeviceReady event
// to continue the load process on devices. Otherwise you will
// be waiting forever (literally) on Desktops.
if ((navigator.platform == 'iPad') ||
(navigator.platform == 'iPhone') ||
(navigator.platform == 'iPod') ||
(navigator.platform == 'iPhone Simulator') ||
(navigator.platform == 'iPadSimulator')
) {
// Listening for this event to continue the load process ensures
// that Cordova is loaded.
document.addEventListener("deviceready", onDeviceReady, false);
} else {
// If we're on Desktops, just proceed with loading Sencha.
loadScript('loader.js', function() {
console.log('Finished loading scripts.');
});
}
};
// This function is a modified version of the one found on
// StackOverflow, here: http://stackoverflow.com/questions/756382/bookmarklet-wait-until-javascript-is-loaded#answer-756526
// Using this allows you to wait to load another script by
// putting the call to load it in a callback, which is
// executed only when the script that loadScript is loading has
// been loaded.
function loadScript(url, callback)
{
var head = document.getElementsByTagName("head")[0];
var script = document.createElement("script");
script.src = url;
// Attach handlers for all browsers
var done = false;
script.onload = script.onreadystatechange = function()
{
if(!done && (!this.readyState
|| this.readyState == "loaded"
|| this.readyState == "complete"))
{
done = true;
// Continue your code
callback();
}
};
head.appendChild(script);
}
function onDeviceReady() {
console.log("[PhoneGap] Device initialized.");
console.log("[PhoneGap] Loading plugins.");
// You can load whatever PhoneGap plugins you want by daisy-chaining
// callbacks together like I did with pgsqlite and Sencha.
loadScript('pgsqlite_plugin.js', function() {
console.log("[Sencha] Adding loader.");
// The last one to load is the custom Sencha loader.
loadScript('loader.js', function() {
console.log('Finished loading scripts.');
});
});
};
</script>
<meta charset="UTF-8">
<title>Sencha App</title>
</head>
<!-- Don't forget to call onBodyLoad() in onLoad -->
<body onLoad="onBodyLoad();">
</body>
</html>
接下來，在你的文檔根目錄創建loader.js定製裝載機，沿着您的index.html。這個主要基於Sencha自帶的開發小型裝載機。很多道具對他們說：
console.log("Loader included.");
(function() {
function write(content) {
document.write(content);
}
function meta(name, content) {
write('<meta name="' + name + '" content="' + content + '">');
}
var global = this;
if (typeof Ext === 'undefined') {
var Ext = global.Ext = {};
}
var head = document.getElementsByTagName("head")[0];
var xhr = new XMLHttpRequest();
xhr.open('GET', 'app.json', false);
xhr.send(null);
var options = eval("(" + xhr.responseText + ")"),
scripts = options.js || [],
styleSheets = options.css || [],
i, ln, path;
meta('viewport', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no');
meta('apple-mobile-web-app-capable', 'yes');
meta('apple-touch-fullscreen', 'yes');
console.log("Loading stylesheets");
for (i = 0,ln = styleSheets.length; i < ln; i++) {
path = styleSheets[i];
if (typeof path != 'string') {
path = path.path;
}
var stylesheet = document.createElement("link");
stylesheet.rel = "stylesheet";
stylesheet.href = path;
head.appendChild(stylesheet);
}
for (i = 0,ln = scripts.length; i < ln; i++) {
path = scripts[i];
if (typeof path != 'string') {
path = path.path;
}
var script = document.createElement("script");
script.src = path;
head.appendChild(script);
}
})();
請注意，您的index.html文件不包含#microloaderscript元素。那是因爲你應該把它拿出來並使用你的自定義加載器。
隨着所有這些，你將能夠順利地航行，知道整個PhoneGap環境在你的Sencha javascript開始做事之前已經到位。
