摘要:[javascript]复制代码代码如下:/***pro_id:产品id*brand_name:品牌*pro_name:产品id*price...

[javascript]

复制代码 代码如下:

/**

*pro_id: 产品id

*brand_name : 品牌

*pro_name : 产品id

*price : 价格

* catalog : 机型

* img : 图片

*file_name : 文件名

*/

var addHistory=function(pro_id,brand_name,pro_name,price,catalog,img,file_name){

stringCookie=getCookie('history');

var stringHistory=""!=stringCookie?stringCookie:"{history:[]}";

var json=new JSON(stringHistory);

var pro_ids = '' ;

jQuery.each(json['history'],function(i,val){

pro_ids+=json['history'][i].pro_id+"," ;

}) ;

if(jQuery.trim(pro_id)=='' || pro_ids.indexOf(pro_id)==-1){

var e="{pro_id:"+pro_id+",brand_name:'"+brand_name+"',pro_name:'"+pro_name+"',price:'"+price+"',catalog:'"+catalog+"',img:'"+img+"',file_name:'"+file_name+"'}";

json['history'].push(e); //添加一个新的记录

setCookie('history',json.toString(),30);

}

}

//显示历史记录

var DisplayHistory=function(){

var p_ele=document.getElementById('history');

while (p_ele.firstChild) {

p_ele.removeChild(p_ele.firstChild);

}

var historyJSON=getCookie('history');

var json=new JSON(historyJSON);

if(displayNum==0){break;}

}

}

//添加一个cookie

var addLi=function(pro_id,brand_name,pro_name,price,catalog,img,file_name,pid){

var a=document.createElement('a');

var href='/proDetail/'+file_name;

a.setAttribute('href',href);

a.setAttribute("target","_blank") ;

jQuery(a).html("<img src='"+unescape(img)+"' onerror="+"this.src='/images/nopic.gif'"+" width='90' height='50' /><h3> "+unescape(brand_name+pro_name+catalog)+"</h3><span>"+unescape(price)+"</span>") ;

var li=document.createElement('li');

li.appendChild(a);

jQuery(li).appendTo("#"+pid) ;

}

//添加cookie

var setCookie=function(c_name,value,expiredays)

{

var exdate=new Date()

}

//获取cookie

function getCookie(c_name)

{

if (document.cookie.length>0)

{

if (c_start!=-1)

{

c_start=c_start + c_name.length+1

if (c_end==-1) c_end=document.cookie.length

return unescape(document.cookie.substring(c_start,c_end))

}

}

return ""

}

// 清除cookie

function DeleteCookie(){

setCookie('history',"{history:[]}",30);

}

json.js

[javascript]

复制代码 代码如下:

var JSON = function(sJSON){

this.objType = (typeof sJSON);

if(this.objType=='string' && ''==sJSON){

sJSON = '{history:[]}' ;

}

this.self = [];

(function(s,o){

for(var i in o){

o.hasOwnProperty(i)&&(s[i]=o[i],s.self[i]=o[i])

};})(this,(this.objType=='string')?eval('0,'+sJSON):sJSON);

}

JSON.prototype = {

toString:function(){

return this.getString();

},

valueOf:function(){

return this.getString();

},

getString:function(){

var sA = [];

(function(o){

var oo = null;

sA.push('{');

for(var i in o){

if(o.hasOwnProperty(i) && i!='prototype'){

oo = o[i];

if(oo instanceof Array){

sA.push(i+':[');

for(var b in oo){

if(oo.hasOwnProperty(b) && b!='prototype'){

sA.push(oo[b]+',');

if(typeof oo[b]=='object') arguments.callee(oo[b]);

}

}

sA.push('],');

continue;

}else{

sA.push(i+':''+oo+'',');

}

if(typeof oo=='object') arguments.callee(oo);

}

}

sA.push('},');

})(this.self);

return sA.slice(0).join('').replace(/[object object],/ig,'').replace(/,}/g,'}').replace(/,]/g,']').slice(0,-1);

},

push:function(sName,sValue){

this.self[sName] = sValue;

this[sName] = sValue;

}

}

加一个cookie

复制代码 代码如下:

addHistory("<%=uuid%>",escape("<%=factoryname%>"),escape("<%=name%>"),escape("<%=price%>"),escape("<%=catalogname%>"),escape("<%=img%>"),escape("<%=file_name%>"));
