Question

我正在使用ASP.net C＃开发的登录页面出现问题。该表单适用于IE，但不适用于Firefox。这是我的样本：

            </div>
        </form>
    </body>
</html>

我注意到这部分......

function ValidarEnter(src)
            {
                if (event.keyCode == "13")
                {
                    actLogin();
                }
            }

当我在firefox上调试它时，它只是跳过它。我已经尝试添加window.event.keyCode ...并且还只用13来切换“13”... 我怎么能解决这个问题？

Answer 1

Firefox不支持

event.keycode。使用event.which for firefox。

function checkKey(evt) {
  var keyID = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
  alert(keyID);
}

Answer 2

当我遇到同样的问题时，我正在研究一个项目。我做了一些RND并找出了这两件事;

  无论浏览器是 Chrome 还是 Firefox ，
e.keyCode都能正常使用onkeydown()功能。

以下 Chrome ＆amp ;; 良好做法的火狐

// HTML (Note onkeydown() function here) <input id="anyId" onkeydown="return myFunction(event)" type="text" /> // JavaScript for it function myFunction(e) { var asciiValue = e.keyCode ; alert ("ASCII Value: " + asciiValue ); // ASCII of pressed key if(asciiValue >0){ return true; } else{ return false; } }



但如果我们在 Firefox 中使用onkeypress()功能，那么e.keyCode将无效。为此，采用var asciiValue= e.keyCode || e.charCode。


// HTML (Note onkeypress() function here) <input id="anyId" onkeypress="return myFunction(event)" type="text" /> // JavaScript for it function myFunction(e) { var asciiValue = e.keyCode || e.charCode ; // It'll handle both Chrome & Firefox alert ("Ascii Value: " + asciiValue); // ASCII of pressed key if(asciiValue>0){ return true; } else{ return false; } }

Answer 3

功能key_fir（e） { e = e || window.event || {}; var charCode = e.charCode || e.keyCode || e.which; if（charCode == 13）{

               //write your code here Like  $("#log_sub").click();
          }
}

event.keyCode在Firefox中不起作用
