支付方法的封装

**最下面有源码**  
这个是我封装的payment方法 封装的有点深  
入过的坑   
1.微信一直返回-1代码错误 可能是因为微信的配置出来问题还有可能需要用正式签名打包  
2.集成支付宝失败 提示是系统繁忙，请稍后再试( ALI64) 这个我记得好像是也是支付的配置出了问题 具体的可能忘了 可以联系支付宝客服解决  
3. 注意layerOpen这个是我找的模仿ios的一个提示窗口 需要的找我要  

在其他页面调用之前需要导入  
<script type="text/javascript" src="utilsJs/paymentUtils.js"></script>  
var paymentUtils = null;  
function plusReady() {  
    paymentUtils = new PaymentUtils();  
    paymentUtils.paymentWayAlert({  
                order_id: order._id,  
                onSuccess: function () {  
                  //支付成功  
                },  
                onFailed: function () {  
                  //支付失败  
                }  
              });  
  }  
if (window.plus) {  
    plusReady();  
  } else {  
    document.addEventListener("plusready", plusReady, false);  
  }  

这个是 PaymentUtils文件的代码  
var PaymentUtils = function () {  
  this.reportLocation = null;  
};  

/**  
 *检查是否安装了支付软件  
 * @param options  
 */  
PaymentUtils.prototype.checkPaymentWay = function (options) {  
  options = options || {};  
  plus.payment.getChannels(function (paymentWay) {  
    if (paymentWay) {  
      options.onSuccess && options.onSuccess(paymentWay);  
    } else {  
      options.onFailed && options.onFailed('获取支付通道列表失败');  
    }  
  }, function (error) {  
    options.onFailed && options.onFailed('获取支付通道列表失败' + error.message);  
  });  
};
