Question

我目前有以下数据表来显示数据库中的联系人列表。每行，我还插入一个“编辑”＆amp; “删除”按钮并传递data-id = "<?=$row['id']?>"，以便jQuery在单击按钮时进行处理。当单击按钮时，通过ajax，我将从getcontact.php获取数据，并将其设置为模式形式的相应输入，但数据似乎不显示在表单值中。我可以知道哪里出错了吗？

tables.php

<table width="100%" class="display table table-striped table-bordered table-hover" id="contactsTable">
                            <thead>

                                        <th>ID</th>

的jQuery

$("#editButton").click(function(e){

 e.preventDefault();

 var uid = $(this).data('id'); // get id of clicked row

 $.ajax({
      url: 'getcontact.php',
      type: 'POST',
      data: 'id='+uid,
      dataType: 'json',
      success: function(response){
          $("#nameInput").val(result[0]);
          $("#companyInput").val(result[1]);
          $("#posInput").val(result[2]);
          $("#contactInput").val(result[3]);
          $("#emailInput").val(result[4]);
          $("#genderInput").val(result[5]);
      }
}); 
});

getcontact.php

<?php
 include("dbconnect.php");

 $id = $_POST['id'];

 $result = mysqli_query($link, "SELECT * FROM businesscontact WHERE id=$id");
 $rows = array();

while($row = mysqli_fetch_array($result)){
$rows[] = $row['*'];
}

echo json_encode($rows);
?>

Answer 1

1 - 您正在从您的php文件发送编码的json并直接从您的javascript代码中使用它，这是无效的，可以这么说，

2 - 您正在使用ajax错误地将数据对象发送到php，它应该如下data: {id: uid},

3 - 您声明了错误的数据ID，它应该如下：var uid = $(this).attr('data-id');

你需要decode你的json回复如下：

var uid = $(this).attr('data-id');
$.ajax({
    url: 'getcontact.php',
    method: 'POST',
    data: {id: uid},
    success: function(response){
    var result = JSON && JSON.parse(response) || $.parseJSON(response);
    ...
    // rest of your code
    ...

更新

你在这一部分遇到了问题：

while($row = mysqli_fetch_array($result)){
    $rows[] = $row['*'];
}

添加您需要执行的整个数组，如下所示：

while($row = mysqli_fetch_array($result)){
    $rows[] = $row;
}

将php echo $ row数据显示为bootstrap模式形式
