原生JS设置、删除、获取Cookie

这边，这边，总结一下原生JS中有关于cookie函数的封装呀~~~

（一）设置cookie 

?

1 2 3 4 5 6

function setCookie(key,val,expires){     var d = new Date();     d.setDate(d.getDate()+expires);       document.cookie = key+"="+val+";path=/;expires="+d; }

（二）删除Cookie

?

1 2 3

function removeCookie(key,val){     setCookie(key,val,-1) }

（三）查看cookie

?

1 2 3 4 5 6 7 8 9 10

function getCookie(key){     var cookie = document.cookie;     var arr = cookie.split("; ");     for(var i=0;i<arr.length;i++){         var newArr = arr[i].split("=");         if(key == newArr[0]){             return newArr[1];         }     } }
