How to submit a form when the return key is pressed?

Question

Can someone please tell me how to submit an HTML form when the return key is pressed and if there are no buttons in the form? The submit button is not there

Answer 1

Here is how I do it with jQuery

j(".textBoxClass").keypress(function(e)
{
    // if the key pressed is the enter key
    if (e.which == 13)
    {
        // do work
    }
});

Other javascript wouldnt be too different. the catch is checking for keypress argument of "13", which is the enter key
