Is it good to use more than one forms on a page?

Question

I want to use multiple forms in one page in my project because RightJS have many good methods for AJAX form handling. But I am afraid that it will lead to problems with speed.

Does it really so?

Answer 1

Having multiple <form> elements can be better for performance, since you're not submitting useless information outside the scope you care about with each submit.

Use as many as appropriate - the units that your information is submitted in, that should be the scope of a particular <form> element, so you're dealing with and submitting only the information you care about with each action.

It's both semantically and performance wise a good move. At the same time, don't go completely overboard and have 100 forms, unless there are actually 100 units of work.

Answer 2

Speed will not be affected by having multiple forms on a page.

Answer 3

As long as multiple forms don't result in bad usability it's fine - why do you think they'll lead to speed problems (they don't unless you maybe have 1000 forms on your page which you hopefully don't plan to do anyway)?

Answer 4

Basically, as good people of stackoverflow already told you, in most cases it will be just fine, but I tell you what. The best way to answer a question like "will it be slow or not" is to implement the thing.

Just write a simple loop, generate a bunch of things on the page and see what happens. In many cases there are too many variables and hidden issues to say for sure what will happen. A little bit of an old fashioned experiment will give you more than hours of wondering around :)
