Question

我正在创建动态发票样式...如果我选择商品代码，那么它将在我的品牌输入ID中显示该商品代码的商品品牌。如果我添加新商品，然后我单击加号按钮添加新项目，然后再次选择一个新项目代码2，然后显示该项目代码2的项目brand2 ...因此，此循环在agiain和agian上进行。

我的ajax调用无法正常工作或ajax代码出现错误....我找不到该错误..如果我不使用ajax调用仅显示所选var itemp 的数据，则它显示选定的 brand 中的数据 itemp ，但是使用ajax调用并找到所选数据 itemp 的 brand 无效。请任何人都可以帮助我。

这是我的javascript ajax调用...

function getprods(val) {
        for (j = 1; j <= count; j++) {
            var itemp = $('#item_code' + j).val();
            $.ajax({
                url: 'ajax_getitems.php',
                type: 'POST',
                data: 'state_id=' + itemp,
                dataType: 'json',
                success: function (data) {
                    var len = data.length;
                    if (len > 0) {
                        var id = data[0]['id'];
                        var brand = data[0]['brand'];

                        document.getElementById('brand' + j).value = brand;


                    }

                }
            });
        }
    }

这是我的ajax_getitems.php文件

<?php

include('conn.php');
$model = $_POST['state_id'];
$sql = "SELECT * FROM product WHERE code='$model'";

$result = mysqli_query($conn, $sql);

$users_arr = array();

while ($row = mysqli_fetch_array($result)) {
    $id = $row['id'];
    $brand = $row['brand'];

    $users_arr[] = array("id"    => $id,
                         "brand" => $brand
    );
}

// encoding array to json format
echo json_encode($users_arr);
exit;

?>

这是我的完整html代码

Answer 1

按如下所示编辑您的php文件。

result.map.with_object({}) { |h, new_h| new_h[h[:label]] = h[:value] }

然后按如下所示编辑ajax部分

<?php
include('conn.php');
$model = $_POST['state_id'];
$sql = "SELECT * FROM product WHERE code='$model'";
$result = mysqli_query($conn, $sql);

// encoding array to json format
echo json_encode($result);
exit;
?>

Answer 2

j <= count;

但是'count'var在哪里？

Answer 3

在 ajax 中添加属性 async: false 可以解决这个问题。

 $.ajax({
          url:"get_response_filter.php",
          method: "POST",
          dataType: 'json',
          async: false,

ajax无法在循环内部工作
