I am using the keynav plugin for the purpose and some extra code for inserting the highlighter into it but all in vain
推荐答案
如果它是 jquery.keynav 插件，即使使用最新的jQuery(v1.6.1)，它也可以正常工作.在计算中，ASCII是字符编码方案，而13是
(输入)键的编号(请参见 ASCII控制字符).
If it is the jquery.keynav plugin that you are using, then it works just fine, even with the latest jQuery (v1.6.1). In computing, the ASCII is a character encoding scheme and 13 is
the number of the ↵ (Enter) key (see ASCII Control characters).
jQuery插件是为箭头键↑ ↓ ← → 设计的选择框和↵ 键触发 .click() 事件.
The jQuery plugin is designed for the arrow keys ↑ ↓ ← → to move the selection box around and the ↵ key to fire the .click() event.
这里是使用该插件的演示.您需要将插件代码另存为 jquery.keynav .js 并将该文件与演示代码放在同一目录中.
Here is a demo that uses the plugin. You will need to save the plugin code as jquery.keynav.js and put that file in the same directory as the demo code.
