greasemonkey: perform GM_xmlhttpRequest() from eval (follow up)
- by Paul Tarjan
How can you call GM_xmlhttpRequest inside of an eval where you are evaling some complicated code, some of which calls GM_xmlhttpRequest.
This is a follow up to http://stackoverflow.com/questions/1074236
Here is some sample code:
// ==UserScript==
// @name Test GM AJAX
// ==/UserScript==
console = unsafeWindow.console;
function fetch(msg) {
console.log('fetching: '+msg);
GM_xmlhttpRequest({
method: 'GET',
url: 'http://google.com',
onload: function(responseDetails) {
console.log(msg);
}
});
}
function complicated(arg1, arg2) {
fetch(arg1 + arg2);
}
console.log('trying');
var code = 'complicated("Ya", "y!")';
function myEval(code) {
eval(code);
eval('setTimeout(function(){'+code+'},0)');
eval('setTimeout(fetch,0)');
eval('setTimeout(function(){console.log("here");fetch("cool")},0)');
fetch("BOO");
}
myEval(code);
which outputs:
trying
fetching: Yay!
fetching: BOO
fetching: Yay!
fetching: 30
here
fetching: cool
BOO
30
So the only fetch that worked was the setTimeout(fetch,0) but I need to actually execute the code which includes come complicated code.
Any ideas?
