我最近在我的jsp页面上有一个文本区域
I recently had a textarea on my jsp page
为此,我在键盘上有自己的快捷键
For it, I had my own shortcuts on the keyboard
然后,我实现了ace编辑器,然后我所有的旧键绑定都不起作用
Then, I implemented the ace editor, and all my old keybindings didn't work then
然后我搜索了一段时间,发现了以下代码:
Then i searched for a while, and found this code:
//I did this before, to add the ace editor var editor = ace.edit("fileInfo"); var JavaScriptMode = ace.require("ace/mode/javascript").Mode; editor.session.setMode(new JavaScriptMode()); //Then I found this for the keyBindings delete editor.keyBinding;最后一行,禁用了ace编辑器中的所有keyBindings,我自己的keyBindings开始起作用... 一切正常,但是随后,我搜索了很多有关ace编辑器的信息,找到了一个有趣的选项,然后是我喜欢使用的一个keyBinding,那就是DELETE ROW键绑定Ctrl + D
The last line, disables all the keyBindings from the ace editor, and my own keyBindings came to work... All worked fine, but then, I searched a lot about the ace editor, and found one interesting option, and thet is the one keyBinding, that I love to use, and that is the DELETE ROW keybinding Ctrl + D
我现在想找回它,但只有它,其他人不能,而且我的旧keyBindings也应该可以工作...
and I want now to get it back, but only it, not the others, and ofc my old keyBindings should also work...
我的旧keyBindings的代码如下:
The code for my old keyBindings looks like this:
document.addEventListener("keydown", function(e) { // Ctrl + S = SAVE if (e.keyCode == 83 && (navigator.platform.match("Mac") ? e.metaKey : e.ctrlKey)) { e.preventDefault(); e.stopPropagation(); if($scope.mode!='BROWSE') { $('#saveBtn').trigger("click"); } } }, false);你能帮我吗?
推荐答案delete editor.keyBinding;不是一个好的解决方案,它将在控制台中产生错误消息
delete editor.keyBinding; is not a good solution, it will produce error messages in console

选项1:删除所有绑定并重新定义我们需要的绑定.
//safely delete all bindings editor.keyBinding.$defaultHandlermandKeyBinding = {} //bind the wanted command editormands.addCommand({ name: "removeline", bindKey: { win: "Ctrl-D", mac: "Command-D" }, exec: function(editor) { editor.removeLines(); }, scrollIntoView: "cursor", multiSelectAction: "forEachLine" });既然您已经定义了命令,则可以根据需要从自己的代码中调用它:
now that you have the command defined, you can call it from your own code if needed:
editor.execCommand("removeline")选择2:实际上是遍历绑定.
使用for (key in obj)遍历键绑定并删除不等于ctrl-d和command-d的键:
Option 2: actually looping through the bindings.
using for (key in obj) to loop through the key bindings and deleting keys that are not equal to ctrl-d and command-d:
for (key in editor.keyBinding.$defaultHandlermandKeyBinding) { if (key !== "ctrl-d" && key !== "command-d") delete editor.keyBinding.$defaultHandlermandKeyBinding[key] }更多推荐
Ace编辑器,如何删除除一个以外的所有keyBindings?
