Question

<script  type = "text/javascript">
    var text = document.getElementById("CKEditor1");

    window.addEventListener("keydown", alert, false);

    functionalert(event) {
        var x = event.keyCode;
        console.log(x);

        if (x == 13) {
            //alert pressed enter key
        }
        else if (x ==35) {
            //presses space bar
        }
    }
</script>

它不起作用。如果有人有想法请分享。使用Javascript / C＃

键入Esc中的输入键或CKEditor键等特定字符时显示提醒消息

Answer 1

请尝试使用以下代码获取ckeditor上的重要事件。

假设或ckeditor实例ID为'CKEditor1'

var ckeditor = CKEDITOR.instances['CKEditor1'];
ckeditor.on('key' , function(event) {
  var x = event.data.keyCode;
  console.log(x);

  if (x == 13) {
    //alert pressed enter key
    alert("pressed enter key");
  }
  else if (x ==32) {
    //presses space bar
    alert("pressed space bar");
  }
});

Answer 2

 var text = document.getElementById("CKEditor1");

 window.addEventListener("keydown", function(event) {
     var x = event.keyCode;
     console.log(x);

     if (x == 13) {
        alert('Esc pressed!');
     }
     else if (x ==35) {
        alert('space bar pressed!');
     }
 });

试试这个。
