按鍵爲火狐

Question

我有一個輸入類型的文本作爲搜索框與搜索按鈕。當有人在搜索框上點擊回車鍵時，它可以在除FF以外的所有瀏覽器中工作。任何人都知道如何修改我的代碼？提前致謝！

<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>

的Javascript

function redirect() { 

      var url = "mylink.com"; 
      var buttonValue;    

      if (document.getElementById('music-button').checked) { 
       buttonValue = document.getElementById('music-button').value; 
      } 

      else if(document.getElementById('books-button').checked) { 
       buttonValue = document.getElementById('books-button').value; 
      } 

      else if (document.getElementById('games-button').checked) { 
       buttonValue = document.getElementById('games-button').value; 
      } 

      else if (document.getElementById('movies-button').checked) { 
       buttonValue = document.getElementById('movies-button').value; 
      } 

      else if (document.getElementById('music-radio').checked) { 
       buttonValue = document.getElementById('music-radio').value; 
      } 

      else if(document.getElementById('books-radio').checked) { 
       buttonValue = document.getElementById('books-radio').value; 
      } 

      else if (document.getElementById('games-radio').checked) { 
       buttonValue = document.getElementById('games-radio').value; 
      } 

      else if (document.getElementById('movies-radio').checked) { 
       buttonValue = document.getElementById('movies-radio').value; 
      } 

      url = url+"&q="+document.getElementById("search-bar").value+"&m="+buttonValue; 
      location.href=url;   
     }   

     $("#music-listener").click(function() { 
      $("#music-button").attr('checked','checked'); 
     }); 

     $("#books-listener").click(function() { 
      $("#books-button").attr('checked','checked'); 
     }); 

     $("#games-listener").click(function() { 
      $("#games-button").attr('checked','checked'); 
     }); 

     $("#movies-listener").click(function() { 
      $("#movies-button").attr('checked','checked'); 
     }); 

     function submitEnter() { 
      var keycode; 
      if (window.event) keycode = window.event.keyCode; 
      else if (e) keycode = e.which; 
      else return true; 

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

Answer 1

傳遞event對象到submitEnter()功能。

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;    
    }
