Submitting a form by pressing enter without a subm

Question

Well I am trying to submit a form by pressing enter but not displaying a submit button. I don't want to get into JavaScript if possible since I want everything to work on all browsers (the only JS way I know is with events).

Right now the form looks like this:

<form name="loginBox" target="#here" method="post">
    <input name="username" type="text" /><br />
    <input name="password" type="password" />
    <input type="submit" style="height: 0px; width: 0px; border: none; padding: 0px;" hidefocus="true" />
</form>

Which works pretty well. The submit button works when the user presses enter, and the button doesn't show in Firefox, IE, Safari, Opera and Chrome. However, I still don't like the solution since it is hard to know whether it will work on all platforms with all browsers.

Can anyone suggest a better method? Or is this about as good as it gets?

Answer 1

Try:

<input type="submit" style="position: absolute; left: -9999px"/>

That will push the button waaay to the left, out of the screen. The nice thing with this is, you'd get graceful degradation when CSS is disabled.

Update - Workaround for IE7

As suggested by Bryan Downing + with tabindex to prevent tab reach this button (by Ates Goral):

<input type="submit" 
       style="position: absolute; left: -9999px; width: 1px; height: 1px;"
       tabindex="-1" />

Answer 2

Just set the hidden attribute to true:

<form name="loginBox" target="#here" method="post">
    <input name="username" type="text" /><br />
    <input name="password" type="password" />
    <input type="submit" hidden="true" />
</form>

Answer 3

Another solution without the submit button:

HTML

<form>
  <input class="submit_on_enter" type="text" name="q" placeholder="Search...">
</form>

jQuery

$(document).ready(function() {

  $('.submit_on_enter').keydown(function(event) {
    // enter has keyCode = 13, change it if you want to use another button
    if (event.keyCode == 13) {
      this.form.submit();
      return false;
    }
  });

});

Answer 4

For anyone looking at this answer in future, HTML5 implements a new attribute for form elements, hidden, which will automatically apply display:none to your element.

e.g.

<input type="submit" hidden />

Answer 5

For those who have problems with IE and for others too.

{
    float: left;
    width: 1px;
    height: 1px;
    background-color: transparent;
    border: none;
}

Answer 6

Use following code, this fixed my problem in all 3 browsers (FF, IE and Chrome):

<input  type="submit" name="update" value=" Apply " 
    style="position: absolute; height: 0px; width: 0px; border: none; padding: 0px;"
    hidefocus="true" tabindex="-1"/>

Add above line as a first line in your code with appropriate value of name and value.
