So, can i do this in jquery: As开发者_Python百科 some one writing in the input field and when hit enter keyword the focus shifts from input field to button.

If you give your input field type="submit", browsers should do this automatically.

Then, if you want your button to do something other than submit the form, you can handle the submit event:

$("#form-id").submit(function() {
    //do something
    return false; //don't submit
});
