这是演示 模拟京东抢购 的js脚本，demo而已，具体商品自行修改
1 登录 网页京东，进入/10024680695127.html，选好参数
2 打开开发者模式,插入如下代码
count=1nIntervId=0 stop=0 var goDate function start(){if (stop==1){clearInterval(nIntervId);//停止监控return }if (Date.now() < goDate){return }console.log(" ^_^ 正在帮你抢购＊＊＊＊＊＊＊＊＊＊＊＊＊ 刷新" + count + "次"+"host:" + window.location.hostname);count++;if ($(parent.frames[0].document).find("#InitCartUrl").length==1){console.log("(++++++++++++正在秒杀");parent.frames[0].document.getElementById("InitCartUrl").click() return}if ($(parent.frames[0].document).find("#GotoShoppingCart").length == 1){console.log("(++++++++++++正在去购物车结算");parent.frames[0].document.getElementById("GotoShoppingCart").click() // 解决购物篮为空的情况// Mixed Content: The page at 'xxx' was loaded over HTTPS, // but requested an insecure resource 'xxx'. // This request has been blocked; the content must be served over HTTPS.var head = document.head || document.getElementsByTagName('head')[0];var style = document.createElement('meta');style.setAttribute("http-equiv", "Content-Security-Policy"); style.setAttribute("content","upgrade-insecure-requests");head.appendChild(style);}if ($(parent.frames[0].document).find(".common-submit-btn").length == 1){console.log("(++++++++++++正在去结算");parent.frames[0].document.getElementsByClassName("common-submit-btn")[0].click() }if ($(parent.frames[0].document).find("#order-submit").length == 1) {console.log("(++++++++++w++正在提交订单");parent.frames[0].document.getElementById("order-submit").click();stop=1 }}// 用frame嵌套目标网页链接的方式，通过重新加载frame的内容（就是current链接）// 来实现“自动刷新”。这样子定时器可以一直运行在页面，实现定时刷新了，// 防止直接刷新，那你所设定的 定时器 在网页刷新重新加载之后会被清掉。。function rewrite(current) {fr4me = '<frameset cols=\'*\'>\n<frame src=\'' + current + '\'/>';fr4me += '</frameset>';with (document) {write(fr4me); void (close()) };}rewrite(window.location.href);var d = prompt("请输入抢购开始时间",'-1-19 20:53:14');//如果返回的有内容if (d) {try {goDate = new Date(d);console.log("设定时间成功:" + goDate);alert("监控期间,请保持标签页在最前面");//go(); 0.25秒执行一次nIntervId = setInterval("start()", 250);}catch (e) {alert("时间格式不正确,请使用yyyy-MM-dd hh:mm:ss格式,精确到秒, 请重试");}}else {alert("请抢购时间, 请重重试");}
