Question

我在angularjs application工作。要通过提醒消息显示未保存的更改，我们已使用window.event.target. Everything works fine in all browsers but Firefox . The错误is window.event未定义。你以前遇到过这个问题吗？你有什么建议可以解决吗？请帮助我们。

 <!DOCTYPE html>
    <html>

    <body>
      <input value="click" type="button" onclick="call()" />
      <script>
        function call() {
          var targ;
          if (!e) var e = window.event;
          if (e.target) targ = e.target;
          else if (e.srcElement) targ = e.srcElement;
          if (targ.nodeType == 3) // defeat Safari bug
            targ = targ.parentNode;
        }
      </script>
    </body>

    </html>

Answer 1

与Chrome不同，事件参数必须在Firefox中定义

   <!DOCTYPE html>
   <html>

    <body>
  <input value="click" type="button" onclick="grabId(event)" />
  <script>
    function grabId(event) {
      var targ;
      if (!e) var e = event;
      if (e.target) targ = e.target;
      else if (e.srcElement) targ = e.srcElement;
      if (targ.nodeType == 3) // defeat Safari bug
        targ = targ.parentNode;
    }
  </script>
</body>

</html>

Answer 2

以下应该可以正常工作：

<!DOCTYPE html>
<html>

<body>
   <script>
    function call(e) {
      var targ;
      if (e.target) targ = e.target;
      else if (e.srcElement) targ = e.srcElement;
      if (targ.nodeType == 3) // defeat Safari bug
        targ = targ.parentNode;
    }
  </script>
  <input value="click" type="button" onclick="call(e)" />

</body>

</html>

window.event.target在firefox中不起作用
