vue 在全局设置cookie main.js文件

//设置cookie

Vue.prototype.setCookie=function(cname, cvalue, exdays) {

　　var d = new Date();

　　d.setTime(d.getTime() + exdays * 24 * 60 * 60 * 1000);

　　var expires = "expires=" + d.toUTCString();

　　console.info(cname + "=" + cvalue + "; " + expires);

　　document.cookie = cname + "=" + cvalue + "; " + expires;

　　console.info(document.cookie);

}

//获取cookie

Vue.prototype.getCookie= function(cname) {

　　var name = cname + "=";

　　var ca = document.cookie.split(";");

　　for (var i = 0; i < ca.length; i++) {

　　var c = ca[i];

　　while (c.charAt(0) == " ") c = c.substring(1);

　　if (c.indexOf(name) != -1) return c.substring(name.length, c.length);

}

return "";

}

//清除cookie

Vue.prototype.clearCookie= function() {

　　this.setCookie("username", "", -1);

}

Vue.prototype.checkCookie= function() {

　　var user = this.getCookie("username");

　　if (user != "") {

　　alert("Welcome again " + user);

　　} else {

　　user = prompt("Please enter your name:", "");

　　if (user != "" && user != null) {

　　this.setCookie("username", user, 365);

}

}
