Here is a synchronous version without jQuery:
function myRequire( url ) {
var ajax = new XMLHttpRequest();
ajax.open( 'GET', url, false ); // <-- the 'false' makes it synchronous
ajax.onreadystatechange = function () {
var script = ajax.response || ajax.responseText;
if (ajax.readyState === 4) {
switch( ajax.status) {
case 200:
eval.apply( window, [script] );
console.log("script loaded: ", url);
break;
default:
console.log("ERROR: script not loaded: ", url);
}
}
};
ajax.send(null);
}
Note that to get this working cross-domain, the server will need to set allow-origin header in its response.
