一、获取cookie:
获取函数:
function getCookie(name) {
var r = document.cookie.match("\b" + name + "=([^;]*)\b");
return r ? r[1] : undefined;
}
调用:
getCookie("username");
二、获取UUID:
获取函数:
function generateUUID() { var d = new Date().getTime(); if(window.performance && typeof window.performance.now === "function"){ d += performance.now(); //use high-precision timer if available } var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = (d + Math.random()*16)%16 | 0; d = Math.floor(d/16); return (c=='x' ? r : (r&0x3|0x8)).toString(16); }); return uuid; }
调用:
generateUUID();
三、计时器:
var num = 60; var timer = setInterval(function () { // 修改倒计时文本 if (num > 1){ // 修改倒计时文本 $("xxx").html(num + '秒'); num -= 1; } else { $("xxx").html('获取验证码'); clearInterval(timer) } }, 1000, 60)
