检测模式对话框上的按键不起作用 [英] detect key press on modal dialog not working

问题描述

我想检测显示模态时用户是否按下了任何键.我尝试了以下代码，但未触发事件.

I would like to detect whether the user has pressed any key when a modal is shown. I tried the following code but the events are not fired.

代码段:

   $("#modal_confirmation_dp_change").on('keydown keyup input', function ( e ) {
         alert();
        });

如果我尝试测试点击事件，则将其触发.

If I try to test click event, it is fired.

   $("#modal_confirmation_dp_change").on('click', function ( e ) {
            alert();
        });

我正在使用Twitter Bootstrap模式.我想念什么吗?

I am using twitter bootstrap modal. Am I missing something?

答案: 我找到了解决我问题的方法.似乎我不应该指向模式的ID，以便可以检测到按键事件.

ANSWER: I found the solution to my problem. It seems like I should not point to the id of the modal so that the keypress event will be detected.

我找到了解决问题的方法.似乎我不应该指向模式的ID，以便可以检测到按键事件.

I found the solution to my problem. It seems like I should not point to the id of the modal so that the keypress event will be detected.

$(document).on('keydown keyup input click',  function (e) {
if($('#modal_confirmation_dp_change').is(':visible')) {
            var key = e.which;
                if (key == 13) { //This is an ENTER 
                    $('#changed_dp_ok').click();
                }
        }
    });
