Cookie计数

“javascript，function setCookie(name, value, days) {， let expires = “”;， if (days) {， let date = new Date();， date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));， expires = “; expires=” + date.toUTCString();， }， document.cookie = name + “=” + (value || “”) + expires + “; path=/”;，}，，function getCookie(name) {， let nameEQ = name + “=”;， let ca = document.cookie.split(‘;’);， for (let i = 0; i˂ ca.length; i++) {， let c = ca[i];， while (c.charAt(0) === ‘ ‘) c = c.substring(1, c.length);， if (c.indexOf(nameEQ) === 0) return c.substring(nameEQ.length, c.length);， }， return null;，}，，function incrementCookieCount(cookieName) {， let count = getCookie(cookieName);， count = count ? parseInt(count) + 1 : 1;， setCookie(cookieName, count, 7); // Set cookie to expire in 7 days，}，，// Example usage:，incrementCookieCount(“pageVisitCount”);，console.log(“Page visit count:”, getCookie(“pageVisitCount”));，“

当然，以下是一段关于cookie计数的JavaScript代码示例：，，“javascript，function setCookie(name, value, days) {， let expires = “”;， if (days) {， let date = new Date();， date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));， expires = “; expires=” + date.toUTCString();， }， document.cookie = name + “=” + (value || “”) + expires + “; path=/”;，}，，function getCookie(name) {， let nameEQ = name + “=”;， let ca = document.cookie.split(‘;’);， for (let i = 0; i˂ ca.length; i++) {， let c = ca[i];， while (c.charAt(0) === ‘ ‘) c = c.substring(1, c.length);， if (c.indexOf(nameEQ) === 0) return c.substring(nameEQ.length, c.length);， }， return null;，}，，function incrementCookieCount(cookieName) {， let count = getCookie(cookieName);， count = count ? parseInt(count) + 1 : 1;， setCookie(cookieName, count, 7); // Set cookie to expire in 7 days，}，，// Example usage:，incrementCookieCount(“pageVisitCount”);，console.log(“Page visit count:”, getCookie(“pageVisitCount”));，`，，这段代码定义了三个函数：setCookie用于设置cookie，getCookie用于获取cookie的值，incrementCookieCount`用于增加指定cookie的计数。
