js cookie清除(解决不同页面下清除失败)

//创建cookiefunction setCookie(data){for(var i=0;i<data.length;i++){document.cookie  = data[i].name+"="+data[i].value+";path=/";}}//获取cookiefunction getCookie(c_name){if(document.cookie.length>0){c_start=document.cookie.indexOf(c_name + "=")if(c_start!=-1){ c_start=c_start + c_name.length+1;c_end=document.cookie.indexOf(";",c_start)if (c_end==-1) c_end=document.cookie.length;return unescape(document.cookie.substring(c_start,c_end));}}return "";}//删除cookiefunction removeCookie(){  document.cookie  = "startTime=;path=/";document.cookie  = "endTime=;path=/";document.cookie  = "param=;path=/";document.cookie  = "user=;path=/";}

 ;path=/这句话很关键 指定到同一路径下 可全局删除  加上着句就可以解决在菜单页面删除cookie 其他页面cookie数据也会清空
