let orderPayFeeStr = this.state.orderPayFee.toString();//商品价格转化为字符串
if(orderPayFeeStr.indexOf(".") != -1){
    orderPayFeepointBefore = orderPayFeeStr.split(".")[0];
    orderPayFeepointAfter = orderPayFeeStr.split(".")[1].length == 1?orderPayFeeStr.split(".")[1]+"0":orderPayFeeStr.split(".")[1];
}else{
    orderPayFeepointBefore = orderPayFeeStr;
    orderPayFeepointAfter = "00";
}
