How to keep a contentScript working when the panel changes location

[Michael Witrant]

Hello,

I have a panel with a contentScript attached. The panel is set to
initially display an URL. If the panel changes its location (through a
click on a link or a `document.location=`), I can't emit messages to
the contentScript anymore (it raises an ERR_DESTROYED, "The page has
been destroyed and can no longer be used.").

Is there a way to keep my contentScript working (or at least reload
it) when the location changes? Or should I avoid changing location
totally an only manipulate the original panel content?

Here's a minimal script showing the behavior:

exports.main = function (options, callbacks) {
panel = require("panel").Panel({
contentURL: "http://google.com/",
contentScript: 'self.port.on("foo", function() { console.log("foo
received"); });'
});

widget = require("widget").Widget({
id: "test-panel",
label: "test panel",
contentURL: "http://google.com/favicon.ico",
panel: panel
});

panel.on("show", function() {
panel.port.emit("foo");
});
};

For now, you should avoid changing the panel's location and only
manipulate the original panel content, since there isn't a way to keep
the content scripts working. But we should probably make the panel's
content scripts get reloaded when its location changes.

But what about if you use an iframe inside of panel and change that
content instead of panel content that probably works

Indeed, using an iframe  works.

Thank you both.

Also please note that iframe is a better option if you need to store state on content side, as otherwise it will be lost on reload.
