jsp中二维码展示及异步轮询查询

接上两篇，微信及支付宝支付请求后需要将二维码url展示并轮询订单查询接口，所以本篇就用jsp简单实现二维码的展示并轮询

二维码展示：

//导入qrcodejs
<script type="text/javascript" src="javascript/qrcode.min.js?r=<%=Math.random() %>"></script>
//创建二维码div

//使用qrcode对象展示二维码
var qrCode ;//二维码对象
function makeCode (id,qrUrl) {
    if (qrCode){
        qrCode.makeCode(qrUrl);
    }else{
        qrCode = new QRCode(document.getElementById(id), {
            width : 207,
            height : 206
        });
    }
    qrCode.makeCode(qrUrl);
}
//将二维码清除
qrCode.clear();//置空

js异步轮询查询接口：

var xhr = '';
//ajax异步访问后端
function post(data, url, type) {
	//请求参数、url、创建XMLHttpRequest
	var data = data;
	var postUrl = url;
	var type = type;//类型： 1，订购下单 2，下单查询
	if (window.XMLHttpRequest) xhr = new XMLHttpRequest();
	// IE浏览器
	else if (window.ActiveXObject) {
		try {
			xhr = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try {
				xhr = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e) {
			}
		}
	}
	xhr.open('post', postUrl);
	//设置header
	xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
	xhr.send(data);
	xhr.onreadystatechange = function () {
		var jsonText = xhr.responseText;
		if (xhr.readyState === 4 && (xhr.status === 200 || xhr.status === 304 || xhr.status === 500)) {
			if ('' !== jsonText) {
				if ('1' === type) {//支付下单
					orderJsonParse(jsonText)
				} else if ('2' === type) {//下单查询
					var jsonP = eval("(" + jsonText + ")");
					var result = jsonP.result;
					var isKeep = jsonP.isKeep;//继续
					if ('1' == isKeep){
						if (result == 0) {//
							clearInterval(inquire);
							hiddenQR();
							window.android.payFinish('1');
						}
					}else {
						clearInterval(inquire);
						if (result == 0) {//
							hiddenQR();
							window.android.payFinish('1');
						} else {//显示主见面
							hiddenQR();
							//显示主界面
							nowI = 0; //interface 主界面：0 其他
							nowF = lastF;
							$(nowF).style.visibility = "hidden";
							$('f_' + nowF).style.visibility = "visible";
							window.android.toast("订购失败");
							window.android.payFinish('-1');
						}
					}
				}
			}
		}
	}
}

//解析下单返回的json
function orderJsonParse(orderjson) {
	$("wait").style.visibility = "hidden";
	var data = JSON.parse(orderjson);
	if (data.result === '0') {
		nowI = 2;
		var qrCodeImg = data.qrCodeImg;
		out_trade_no = data.outTrade;
		nowF = 'tip3';
		$(nowF).style.visibility = "visible";
		//重新生成图片
		$(nowF + '_1').src = "http://111.19.132.254:8088/joymusic_cs_gwb/imgerU?pic=http://111.19.132.254:8088/joymusic_cs_gwb/images/common/order/gwb/qr_bj_"+payType+".png&type=watermark&z=" + productName + "," + priceStr + "&s=22&x=435&y=250&x2=400&y2=320&rand=<%=Math.random()%>";
		$(nowF + '_1').style.visibility = "visible";
		//qrCode.clear();//置空
		makeCode('qrCodeImg',qrCodeImg);
		$('qrCodeImg').style.visibility = "visible";//将二维码div生成显示
		$('ico').style.visibility = "visible";
		//将num置零
		num = 0;
		//定时器 定时查询
		setTimeout(checkOrder(),3000);
	} else {
		//下单失败
		window.location = 'pay.jsp?k=0&userid=' + userId + '&platform=' + platform + '&ip=' + ip + '&terminalId=' + terminalId + '&token=' + token + '&songId=' + songId;
