Dynamically loading JavaScript synchronously
- by spoon16
I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module.
I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load?
function myModule() {
var tag = document.createElement("script");
tag.type = "text/javascript";
tag.src = "http://some/script.js";
document.getElementsByTagName('head')[0].appendChild(tag);
//something should go here to ensure file is loaded before return is executed
return {
external: externalVariable
}
}
