Ok it is alerting error2. After it alerts error2 it alerts bla22... self recursion? wtf?

 

	function update(fInp, valu) {
	alert('bla1');
	var ord = document.getElementById('ctrordernumber').value;
	alert('bla2');
	alert (fInp.length);
	alert (valu.length);
	if(fInp.length != 0 && valu.length != 0){
		$.post("updateorder-exec.php", {field: ""+fInp+"", val: ""+valu+"", on: ""+ord+""}, function(data){
			alert('bla22');
			if(data.length >0) {
				alert('bla3');
				if(data) {
					//$('#errDiv').show();
					//$('#errDiv').html("Database updated!");
					alert('updated');
					//$('#errDiv').css('opacity',100).fadeOut(10000);
				} else{
					alert('error');
					//$('#errDiv').show();
					//$('#errDiv').html("Error. Incorrect information entered!");
					//$('#errDiv').css('opacity',100).fadeOut(10000);
				}
				return data;
			}
		});
	}
	alert('error2');
	//$('#errDiv').show();
	//$('#errDiv').html("Error. Incorrect information entered!");
	//$('#errDiv').css('opacity',100).fadeOut(10000);

	return 0;
}

You call alert('bla22') in the callback function, so that doesn't get triggered until your file is loaded with $.post. It just keeps going on with the code and then executes the callback function when the file is actually loaded.

 

Why does it matter, though?

I found out I need a synchronous call Everything has to be done in order because this function is not returning the information that it needs to return before another function executes what it needs to do.
