基于 Jquery操作Cookie记录用户查询过信息

	  

		
 代码如下
		
复制代码
	  
	  

		
function getid(id) {

}

//如果是一个没有True的input不执行

}

function Init() {

//取出Cookie
var icpSite = $.cookie("site");
if (icpSite) {
//取出Cookie不为空的话就给当前框
icpSite = icpSite.split('|')[0];
$("#site").val(icpSite);
}
}
	  
	

	  

		
 代码如下
		
复制代码
	  
	  

		
            onmouseover="this.style.display='block'" onmouseout="this.style.display='none'">
            

            

        

   

	  
	
除此之外的JS直接放在一个Js文件里，引用进来就行了

//加载列表

	  

		
 代码如下
		
复制代码
	  
	  

		
function FillUrls(cookieName) {
var urls = $.cookie(cookieName);
var html = "";
if (urls) {
var urllist = urls.split('|');
var forlength = 0;
var stringcookie;
for (var i = urllist.length - 1; i >= 0; i--) {
var textval = urllist[i];
if ($.trim(textval) != "" && $.trim(textval) != "undefined") {
html += "
" + textval + "

";
forlength = forlength + 1;
if (forlength > 10) {//在这里我只加载10条，大家可以根据自己的情况进行调整
$.cookie("site", stringcookie, { expires: 7 });
break;
} else {//如果超出10个的话就取最后10个
stringcookie = textval + "|" + stringcookie;
}
}
}
} else {
html += "
没有记录
"
}
getid("allSitesBoxContent").innerHTML = html;
}
	  
	

//操作Cookie类

	  

		
 代码如下
		
复制代码
	  
	  

		
function setCookie(name, value) {

var oldcookie = $.cookie(name);
if (oldcookie == null) {
$.cookie(name, value, { expires: 7 });
} else {
if ($.cookie(name).indexOf(value) == -1) {
$.cookie(name, oldcookie + "|" + value, { expires: 7 });
} else {
$.cookie(name, oldcookie.replace(value, "") + "|" + value, { expires: 7 });
}
}
FillUrls(name);
}
	  
	
调用 时这样写

	  

		
 代码如下
		
复制代码
	  
	  

		
setCookie("site", strdomin);

	  
	
好了功能完成，大家如果想看真实效果的话，就来http://zz.111com.net 

进行具体的测试

$.cookie("domain", value, { expires: 7, domain: "7c.com" });
