Codemirror onKeyEvent不触发 [英] codemirror onKeyEvent not firing

问题描述

我正在尝试让代码镜像显示提示功能，我已经设法使其与 extraKeys 一起使用，这可以很好地加载getHints函数，但是我真的希望它与 onKeyEvent ，但这似乎无能为力，我什至无法发送警报消息

I am trying to get codemirrors show hint functionality to work I have managed to get it to work with extraKeys this loads the getHints function fine but I really want it to work with onKeyEvent but this doesn't seem to do anything I can't even get it to send an alert message

function getHints(cm) {
// find the words
}

$(document).ready(function(){
CodeMirror.registerHelper("hint", "logger", getHints);
CodeMirror.commands.autocomplete = function(cm) {
    cm.showHint({hint: CodeMirror.hint.logger});
  }
var editor = CodeMirror.fromTextArea(
    $("#log").get(0),
    {
        extraKeys: {"Ctrl": "autocomplete"},
        onKeyEvent: function(e, s) {
                var kc = s.keyCode;
                if (s.type == "keyup") {
                    if (kc != 38 && kc != 40 && kc != 13 && kc != 27 && kc != 32) {
                        alert(kc);
                        CodeMirror.commands.autocomplete(e);
                    }
                }
            }
    });
});

在这里，我正在玩的游戏我什至不知道我在做什么错，即使尝试使用jquery触发器似乎也无济于事:/ http://jsfiddle.net/f2n74k3s/7/

Heres what I was playing with I have no idea what I am doing wrong even trying to use jquerys trigger doesnt seem to do anything :/ http://jsfiddle.net/f2n74k3s/7/

推荐答案

onKeyEvent 在CodeMirror的API中不存在.因此，可以保证它不起作用.使用 extraKeys ，它是为此类任务而构建的.

onKeyEvent does not exist in CodeMirror's API. Hence, it is guaranteed not to work. Use extraKeys, it is built for this kind of task.
