ajax函数体：（出现过写在上面不加载的问题，推荐放在页面下方）

<script src="/Application/Tpl/App/default/Public/Static/js/jquery-1.9.1.min.js"></script>
<script language="javascript">
function callpay(num)
{
    $.ajax({
        url:"./index.php?g=App&m=Index&a=ajaxqianpay",
        type:"POST",
        data:‘payNum=‘+num,
        success:function(msg){
            alert(msg.data);
            if(msg.data==‘right‘){
                document.getElementById(‘payDom‘).style.display=‘none‘;
                document.getElementById(‘successDom‘).style.display=‘‘;
                setTimeout(‘window.location.href="/index.php?g=App&m=Index&a=order"‘, 3000);
            }else{
                document.getElementById(‘payDom‘).style.display=‘none‘;
                document.getElementById(‘failDom‘).style.display=‘‘;
            }
        }
    });
}

</script>

后台:

 1 public function ajaxqianpay(){
 2         $uid = $_SESSION[‘uid‘];
 3         $moneyBySql = M(‘User‘)->where(‘id=‘.$uid)->field(‘price,d_price‘)->find();
 4
 5         if($moneyall<=$_POST[‘payNum‘]){
 6             $this->ajaxReturn(array(‘wrong‘),‘failed‘,0);
 7             }else{
 8                 $this->ajaxReturn(array(‘right‘),‘success‘,1);
 9                 }
10   }
