##第一版function my_bid(username, max_price){var now_username = $($('.auctioninfo tr:first td')[0]).html();var price_span = $('.auctioninfo tr:first td')[1];var price = $(price_span).children('span').html();var now_price = parseInt(price) + Math.ceil(Math.random() * 5);if (now_username != username && now_price <= max_price){$('input[class="text quantity-text"]').val(now_price);$('#buy-btn').click();}}setInterval("my_bid('fxhover', 2400)", 100);
##改进版function my_bid(id, username, max_price){$.getJSON('http://auction.jd.com/json/paimai/bid_records?t=1426817263311&dealId='+ id +'&pageNo=1&pageSize=1', function(data){var price = data.datas[0].price;var now_username = data.datas[0].userNickName;var now_price = parseInt(price) + Math.ceil(Math.random() * 10);if (now_username != username){if (now_price <= max_price){$('input[class="text quantity-text"]').val(now_price);$('#buy-btn').click();} else{alert('超过最大预算，停止竞标！');}}});}var id = document.location.href.split('/').pop();setInterval("my_bid(" + id + ", 'fxhover', 300)", 1);
