document.foo.submit();

Yeah, that much I'm familiar with; I've personally seen examples of sites that use scripts to submit forms. This is no problem for scripting, because instead of executing the script you just submit the form. Sometimes the script does some other things before it submits the form, such as changes some field values. In that case, you just do that first, then submit the form.

However, it can be extended by creating a class of functions to submit multiple forms at the same time.

That's what I haven't seen and wouldn't know how to do. (How do you stop your script from ceasing to execute when the first form is submitted? Or is Javascript multithreaded these days? Where do the extra result pages go, then? Do they pop up in extra windows, or what?) Anyway, that's some pretty weird stuff, submitting multiple forms at once. Sites ought not to do such things. Sometimes I wish LiveScript had never been developed.
