jquery快捷动态绑定键盘事件的操作函数代码_jquery

(function($)
{
$.extend({

key_fn:[], //存放绑定的字符对应的函数
key_code:[], //存放字符
key_bind:function(ch,callback){
var KeyCode = {a:65,b:66,c:67,d:68,e:69,f:70,g:71,h:72,i:73,j:74,k:75,l:76,m:77,n:78,o:79,p:80,q:81,r:82,s:83,t:84,u:85,v:86,w:87,x:88,y:89,z:90};

if(KeyCode.hasOwnProperty(ch)){
$.key_fn.push(callback);
$.key_code.push(ch);
//第一次才需要添加事件
if($.key_fn.length == 1){

$(document).keypress(function(e){
var e = event || window.event;
var k = e.keyCode || e.which;

for(var i =0 ; i
// - 32 兼容小写
if(k-32 == KeyCode[$.key_code[i]] || k == KeyCode[$.key_code[i]] ){
log('pressed binded key '+k);
$.key_fn[i]();
break;
}
}

});
}
}else
{
alert('绑定事件只能是字母');
}
}

});
})(jQuery);

$.key_bind('f',set_table_full_screen);
$.key_bind('r',reloadthis);

$(document).keypress(function(){})
