How to include onsubmit to return or validate two functions?

onsubmit is a form attribute, not a field attribute.

Ok I want to validate two function on onsubmit. How will i do that?

When the user goes for sign-in(Login button) the function validate1() should get validated and for sign-up(Register button) function validate() should get validated. How will i do this? Please help me.

Instead of validating the function I just added the required in the text fields.

Note that "required" only works for HTML5-compliant web clients. HTML4 did not support this feature. So, for example, IE9 and earlier, this won't work.

Then what should I do to validate both the function?

I said on th other thread about this html, why are you uing a single form for something that is clearly two forms.
Also you still have multiple fields with the same id (user and pass).  This is wrong.

In fact, this is a violation of proper XML document formation. The XML spec, of which HTML specs are derivative, says that each element must have a unique id value. Failure to observe this restriction can have unpredictable results. Especially if you start browsing the DOM using get element by ID.

And, as Dave has said. Using 1 form to do the work of 2 is not a good idea. Also, forms cannot be nested, so don't even think of doing that!

I have two tabs. One for Sign-In and the second for sign-up. So the sign-in has two fields username and password and sing-up has three with same username, password and email. So when the user sign-up it should validate the function for all three fields

And when the user tries to sign-in with empty username and password field, it should alert the else if condition only. How will i validate this? Please help me.






Added the servlet code and how the form looks for your reference.

You don't seem to be heeding the advice to split your form into two separate forms. Or to be sure that your id values are unique.

Its not that i am not taking the advice, but i don't know how to separate the tab activity. In same structure but in two different forms.

What do you mean by the id values are unique?

You should have one form inside your sign-in-htm div, and another inside the sign-up-htm. Each should have their own validation function, and each should be processed by a different servlet controller.

You can share code with smaller functions, but for now concentrate on getting the structure correct. Optimizations can come later.

You have multiple elements withe the same id value ("user" for example). That's not valid HTML.

My advice would be to use class names instead of id values to identify the fields; but if you are going to use id values, they must be unique within the entire HTML page.

So i should have separate for like for sign-up . Is this correct?

What is happening now?  Are you getting desired output?

Assuming those servlets do what you need, then yes.

But you still need to rename your clashing id fields (user and pass).

No i am not getting the desired output. So I just kept one servlet.

As I didn't get the desired output, i just merged both to one file. Should i need to rename the user and pass for either sign-up-htm or sign-in-htm?

Else now i am trying to show a popup form when we click the login button.


The above code how will i display the login page in a popup while clicking login button?

I just changed the user id and password id in singn-in-htm but both the sign-up and sign-in points to same servlet with different fields. Now how will i do?

The id, not the name...


As Tim said earlier, XML requires you to have unique id values to be valid.

Besides, you are still using a single form for two actions.
Sign-up is not the same thing as Sign-in.
