Chevereto 更改键盘快捷键
在查看图像预览的时候，关闭图片的快捷键是 “X” ，而我们想使用 “Esc” 键代替它，
作者 Rodolfo 给出的方案是：
- 在文件 https://github.com/Chevereto/Chevereto-Free/blob/master/app/lib/chevereto.js#L2009 修改它的键代码，
- 查看下表可知：
“Esc” => "27" - 则可在第 #L2009
88: 'close'修改为27: 'close'
//原代码
keys: {
83: 'select',
76: 'like',
70: 'flag',
69: 'edit',
65: 'move',
46: 'delete',
88: 'close', //<--- 此处需要修改 （88=>27）
37: 'prev',
39: 'next',
},
//修改后
keys: {
83: 'select',
76: 'like',
70: 'flag',
69: 'edit',
65: 'move',
46: 'delete',
27: 'close',
37: 'prev',
39: 'next',
}, 对应键代码详细如下表
In every browser there are three possible kinds of client-side events triggered when a keyboard key is pressed or released:
- keydown event
- keypress event
- keyup event
The keydown event occurs when the keyboard key is pressed, and it is followed at once by the execution of keypress event.
The keyup event is generated when the key is released.Here is a sample program using the keycodes You can view it's source to the the actual coding
