获取cookie，设置cookie，删除cookie

//获取cookie

export const getCookie = (name) => {

var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");

if (arr = document.cookie.match(reg))

return (arr[2]);

else

return null;

}

//设置cookie

export const setCookie = (params) => {

var exdate = new Date();

exdate.setDate(exdate.getDate() + expiredays);

document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString());

}

//删除cookie

export const delCookie = (params) => {

var exp = new Date();

exp.setTime(exp.getTime() - 1);

var cval = getCookie(name);

if (cval != null)

document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();

}
