Question

我有一个输入类型文本，可以作为搜索框和搜索按钮。当有人点击搜索框上的回车键时，它可以在除FF之外的所有浏览器中使用。有人知道修改我的代码吗？提前谢谢！

            else
               return true;

Answer 1

将event对象传递给submitEnter()函数。

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;            
    }
