Keypress for Firefox

Question

I have an input type text that acts as a search box along with a search button. When someone hits the enter key on the search box it works in all browsers except for FF. Anyone know a way around to modify my code? Thanks in advance!

HTML

<input type="text" name="search-bar" id="search-bar" class="search-box" onkeypress="return submitEnter();" placeholder=" Start typing to search"/>

<button onclick="redirect();" class="search-button" id="lang-search">Search</button>

<dl id="sample" class="dropdown">
            <dt><a href="#"><img src="images/menu-icon.png" alt=""></a></dt>
            <dd>
                <ul>
                    <li>
                        <input type="radio" name="selection" value="music" id="music-button"><img id="music-listener" class="dropdown-select" src="images/music-icon.png" alt="music">
                    </li>

                    <li>
                        <input type="radio" name="selection" value="books" id="books-button"><img id="books-listener" class="dropdown-select" src="images/books-icon.png" alt="books">
                    </li>

                    <li>
                        <input type="radio" name="selection" value="games" id="games-button"><img id="games-listener" class="dropdown-select" src="images/games-icon.png" alt="games">
                    </li>

                    <li>
                        <input type="radio" name="selection" value="movies" id="movies-button"><img id="movies-listener" class="dropdown-select" src="images/movies-icon.png" alt="movie">
                    </li>                       
                </ul>
            </dd>
        </dl>           

        <div class="clear-float"></div>

        <input type="radio" name="selection" value="music" id="music-radio" class="radio-button"><span class="radio-text" id="lang-music">Music</span>

        <input type="radio" name="selection" value="books" id="books-radio" class="radio-button"><span class="radio-text" id="lang-books">Books</span>

        <input type="radio" name="selection" value="games" id="games-radio" class="radio-button" ><span class="radio-text" id="lang-games">Games</span> 

        <input type="radio" name="selection" value="movies" id="movies-radio" class="radio-button" ><span class="radio-text" id="lang-movies">Movies</span> 

Javascript

 function redirect() {

            else return true;

            if (keycode == 13)
               {
              redirect();   
              return false;

            else

        }   

Answer 1

Pass the event object to the submitEnter() function.

HTML:

<input type="text" name="search-bar" id="search-bar" class="search-box" onkeypress="return submitEnter(event);" placeholder=" Start typing to search"/>

JS:

function submitEnter(event) {
        var keycode = event.keyCode ? event.keyCode : event.which;

        if (keycode == 13)
           {
          redirect();   
          return false;
           }
        else
           return true;            
    }
