Forcing a script to load in Safari -- help needed

Jul 11th, 2005

Hi,

I've been beating my head against my inability to force Safari to dynamicall
y load an external Javascript file, and was wondering if anyone has any advi
ce. My current code works fine in Firefox and IE:

var e = document.createElement("script");

e.src = url;
e.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(e);

I want the script to load and then execute. Any suggestions?

I am afraid that I do not have a safari browser to test on. However, I did find, when testing with IE and Firefox, that I had to wait some time for some scripts to be loaded.

I used this code *similar* to this to load script files and check the function I want to load exists... sometimes it can take a few iterations before the function is available to the web page.

function importLibFile(file){
	var e = document.createElement("script");
	e.src = file;
	e.type="text/javascript";
	document.getElementsByTagName("head")[0].insertBefore(e, document.getElementsByTagName("script")[0]);
}

function loadPackage(func, libFile){
	if(document.libraries && !document.libraries[libFile]){
		document.libraries[libFile] = true;
		importLibFile(libFile);
	}
	try {
		func(null, function(s){alert(s);});
		document.getElementsByTagName("body").item(0).innerHTML += (libFile + " package loaded." +"<br/>");
	} catch(exception) {
		document.getElementsByTagName("body").item(0).innerHTML += ("Loading package " + libFile +"<br/>");
		// while appfunction doesn't load
		setTimeout(function(){ loadPackage(func, libFile); }, 250);
	}
}
