加载在Chrome浏览器打包应用程序通过XHR本地内容 [英] Loading local content through XHR in a Chrome packaged app
问题描述
我想在一个Web应用程序使用我的骨干已经建立加载和它拉在存储在本地JSON和HTML模板文件。我想知道用浏览器打包应用程序是否有可能通过某种'得到'/ Ajax请求加载这些文件？
I'm trying to load in a web app that I've built using Backbone and it pulls in JSON and HTML template files that are stored locally. I was wondering with Chrome packaged apps whether it's possible to load these files by using some sort of 'get'/ajax request?
目前我得到这个...
Currently I'm getting this...
OPTIONS chrome-extension://fibpcbellfjkmapljkjdlpgencmekhco/templates/templates.html Cannot make any requests from null. jquery.min.js:2
XMLHttpRequest cannot load chrome-extension://fibpcbellfjkmapljkjdlpgencmekhco/templates/templates.html. Cannot make any requests from null.
我无法找到如何做到这一点，因此任何帮助将是巨大的感谢任何真实的信息！
I can't find any real information on how to do this so any help would be great thanks!
推荐答案
是的，这是完全可能的，而且很容易。这里的工作示例。尝试从这个，确认它的工作原理，然后再重新添加在自己的code。如果碰到一个障碍，并拿出一个比XHRs无论是在打包应用程序的工作更具体的问题，你可能要问一个新问题。
Yes, it's totally possible, and it's easy. Here's a working sample. Try starting with this, confirm that it works, and then add back in your own code. If you hit a roadblock and come up with a more specific question than whether XHRs work in packaged apps, you might want to ask a new question.
的manifest.json：
manifest.json:
{
"name": "SO 15977151 for EggCup",
"description": "Demonstrates local XHR",
"manifest_version" : 2,
"version" : "0.1",
"app" : {
"background" : {
"scripts" : ["background.js"]
}
},
"permissions" : []
}
background.js：
background.js:
chrome.app.runtime.onLaunched.addListener(function() {
chrome.app.window.create("window.html",
{ bounds: { width: 600, height: 400 }});
});
window.html：
window.html:
<html>
<body>
<div>The content is "<span id="content"/>"</div>
<script src="main.js"></script>
</body>
</html>
main.js
main.js:
function requestListener() {
document.querySelector("#content").innerHTML = this.responseText;
};
onload = function() {
var request = new XMLHttpRequest();
request.onload = requestListener;
request.open("GET", "content.txt", true);
request.send();
};
content.txt：
content.txt:
