js cookise实例

1：将信息加入cookise

var cInfoId = document.getElementById("goods_id").value;
	var cCustId = document.getElementById("get_cust_id").value;
	var cImgurl = document.getElementById("imgsrc").value;
	var cShopPrice = document.getElementById("shopPrice").value;
	
	
	var addCookie=function(objName,objValue,objdays){
      var str = objName + "=" + escape(objValue);
      if(objdays > 0){//为0时不设定过期时间，浏览器关闭时cookie自动消失
          var date = new Date();
          var ms = objdays*3600*1000*24;
          date.setTime(date.getTime() + ms);
          str += ";expires=" + date.toGMTString();
      }
      document.cookie = str+";path=/";
  }
  
  var  cookieInfo ="<a href=/goods_detail-"+ cCustId + "-"+ cInfoId +".html target=_blank>"
	               +"<img src="+cImgurl+" width=48 height=48></a>"
	               +"|"+cShopPrice;
  addCookie("cookie-"+cInfoId,cookieInfo,30);//默认保留一个月

2:遍历cookise里的信息

//---parser cookise
			var arrStr = document.cookie.split(";");
			if(typeof(arrStr)!='undefined' && arrStr.length>1){
		      for(var i = 0;i < arrStr.length;i ++){
		          var temp = arrStr[i].split("=");
		          if(temp.length == 2){
		          	 if(temp[0].indexOf("cookie-")>-1){
		          	 	 document.write("<dl><dt>");
		          	 	 var c_info = unescape(temp[1]).split("|");
		          	 	  document.write(c_info[0]);
		          	 	  document.write("</dt>");
		          	 	  document.write("<dd>￥<span>");
		          	 	  document.write(c_info[1]);
		          	 	  document.write("</span></dd></dl>");
		          	 	}
		          }
		      } 
		  } else {
		  		  document.write("&nbsp;&nbsp;&nbsp;&nbsp;<font color=#666666>暂无商品浏览记录</font>");
		  }

3：删除cookise

	function delCookie(){
					var arrStr = document.cookie.split(";");
				  if(typeof(arrStr)!='undefined' && arrStr.length>1){
			      for(var i = 0;i < arrStr.length;i ++){
			          var temp = arrStr[i].split("=");
			          if(temp.length>1){
			          		var date = new Date();
								    date.setTime(date.getTime()- 365*24*3600*1000);
								    document.cookie=temp[0]+"=v;expires="+date.toGMTString()+";path=/";
			          }
			       }
				  }
			    window.location.reload();
			}
