Question

我在使用ajax获取多个数据时遇到问题。

我有购物车，如果我添加（+）更多数量然后崩溃，一个数据参数它可以正常工作，但如果我尝试多次，它会给出奇怪的大数字。

如果我不使用增值税+总费用，那么它可行，但如果我使用增值税+总计我得到多个点数..

示例：251.52254.5141.92 //不含增值税且总成本价格为251,52（251.52 254.51 41.92）例2：262264.9943.6666666667 //增加了一个数量......

的Ajax：

$(document).ready(function() {                           
  $("#btnplus<?php echo $i;?>").click(function() {   
    $.post("<?php echo $baseurl;?>/api-cart-update.php",{ 
      unique: "<?php echo $unique;?>",
      cccid: "<?php echo $data['id'];?>",
      act: "plus"
    },

      function(data) {
        $('#chk<?php echo $i;?>').html(data);
        $('#sum<?php echo $i;?>').html(data);
        $('#km<?php echo $i;?>').html(data);
      });
  });

  $("#btnminus<?php echo $i;?>").click(function() {
    $.post("<?php echo $baseurl;?>/api-cart-update.php",{ 
    unique: "<?php echo $unique;?>",
    cccid: "<?php echo $data['id'];?>",
    act: "minus"
  },

    function(data) {
      $('#chk<?php echo $i;?>').html(data);
      $('#sum<?php echo $i;?>').html(data);
      $('#km<?php echo $i;?>').html(data);
    });
  });
});

API-车-update.php：

require_once('function.php');

if(isset($_POST['unique'])) {

$un = $_POST["unique"];
$act = $_POST["act"];

try{
    $database = new Connection();
    $db = $database->openConnection();

$sum=0;
$tarne=2.99;

if($act=="plus"){
    $will = $qnow['qty']+1; 


}else{
    $will = $qnow['qty']-1;

}

if($will<=1){

$km = $subttl - $priceBeforeVat;



if($stmt){
    echo "$subttl";
    echo "$sum";
    echo "$km";

}

}
}

试试这个：

$.ajax({
    url: 'YOUR URL',
    type: 'post',
    dataType: 'json',
    data: {
        'POST1': 'variable',
        'POST2': 'variable'
    },
    success: function(data) {
        alert(data.array1);
    }
});

在你的PHP文件上

if (isset($_POST['POST1'])) {
  //'DO SOME THING';
  json_encode(array(array1=>'bla bla',array2=>'ble ble'));
}
