I'm trying to display remote images in a FireFox add-on panel, but the src attributes are being converted from something like this:
http://example.com/image.jpg
to something like this:
resource://addon_name/data/%22http://example.com/image.jpg%22
I can't figure out if I'm breaking a security policy or not.
In my add-on script (index.js) I'm retrieving image URLs using the sdk/request API and passing them to my content script (data/my-panel.js). My data/my-panel.js file is creating DOM elements in my panel file (data/popup.html) – including images – using the URLs passed from index.js. Here are the relevant bits of code:
index.js
var Request = require("sdk/request").Request;
var panel = require("sdk/panel").Panel({
width: 500,
height: 500,
contentURL: "./popup.html",
contentScriptFile: "./my-panel.js"
});
Request({
url: url,
onComplete: function(response) {
// Get the JSON data.
json = response.json;
// Launch the popup/panel.
panel.show();
panel.port.emit("sendJSON", json);
}
}).get();
data/my-panel.js
var title;
var desc;
var list;
var titleTextNode;
var descTextNode;
self.port.on("sendJSON", function(json) {
json.docs.forEach(function(items) {
title = JSON.stringify(items.sourceResource.title);
desc = JSON.stringify(items.sourceResource.description);
img = JSON.stringify(items.object);
console.log(img);
var node = document.createElement("li"); // Create a <li> node
var imgTag = document.createElement("img"); // Create a <img> node
imgTag.setAttribute('src', img);
imgTag.setAttribute('alt', desc);
imgTag.style.width= '25px';
titleTextNode = document.createTextNode(title);
descTextNode = document.createTextNode(desc);
node.appendChild(titleTextNode); // Append the text to <li>
node.appendChild(descTextNode); // Append the text to <li>
document.getElementById("myList").appendChild(node); // Append <li> to <ul> with id="myList"
document.getElementById("myImgs").appendChild(imgTag);
});
});
The console.log(img) line is displaying the URLs correctly, but not in popup.html...
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<ul id="myList"></ul>
<p id="myImgs"></p>
</body>
</html>
How can I make the images' src attributes point directly to the remote URLs?
Thanks!
