js或者jquery動態更改a標簽的linkhovervisitedactive不同的變換？

代碼示例：

$(document).ready(function(){

$("#ceshia").mouseover(function(){

var underline=$("#underline").val();

if(underline==1 ||underline==2) {

var xia="underline";

}

else {

var xia="none";

}

var hover=$("#hover").val();

$("#ceshia:hover").css({

"color":hover,"text-decoration":xia

}

);

}

);

$("#ceshia").mouseout(function(){

var underline=$("#underline").val();

if(underline==0 ||underline==2) {

var xia="none";

}

else {

var xia="underline";

}

var links=$("#link").val();

$("#ceshia:link").css({

"color":links,"text-decoration":xia

}

);

}

);

$("#ceshia").mousedown(function(){

var underline=$("#underline").val();

if(underline==0 ||underline==2) {

var xia="none";

}

else {

var xia="underline";

}

var active=$("#visited").val();

$("#ceshia:active").css({

"color":active,"text-decoration":xia

}

);

}

);

}

);
