通过在锚标记中使用 data-id 属性，使用 jquery 将值传递给模式弹出窗口

Question

<div class="login-group">
<div class="form-group">

上面的代码显示了来自数据库的值，其中 data-id 作为锚标签中的服务 id

这个数据ID应该显示在模式弹出窗口中，在下面找到

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="padding-top: 150px;">
    <div class="modal-dialog">

                    </table>

                    <?php
                    if(isset($_REQUEST["book"]))
                    {
                        if($_REQUEST["book"])
                        {
                            $service_id=$_REQUEST["service_id"];
                            $customer_id=$_REQUEST["cust_id"];
                            $slot1_dt=$_REQUEST["slot1_dt"];
                            $slot2_dt=$_REQUEST["slot2_dt"];
                            $slot1_tm=$_REQUEST["slot1_tm"];
                            $slot2_tm=$_REQUEST["slot2_tm"];

                            if($res)
                            {
                                echo("successful.....");
                            }
                        }
                    }
                    ?>
            </div>
        </div>
        <div class="modal-footer"></div>
    </div>
</div>
</div>

用于传值的jquery是

<?
$(".modalLink").click(function () {
var passedID = $(this).data('id');
$('#id').val(passedID);

//modifies input in modal
$(".modal-body .hiddenid").val(passedID);});
?>

这些代码在单个 php 文件下，js 存储为单独的文件

在输出上我无法获取要传递的数据 ID 值

文本字段仍然为空。

请大家帮帮我。

Answer 1

首先，用href="#myModal".删除href="#"

<a href="#" data-id="<?php echo $obj["service_id"]; ?>" data-toggle="modal" data-target="#myModal" class="modalLink">
    <img src="<?php echo '../assets/img/'.$obj['service_image']; ?>" alt="" >
</a>

其次，这不是打电话data-id.的方式 删除 var passedID = $(this).data('id'); 和 var dataId=$(this).attr('data-id'); 如下所示。

<?
$(".modalLink").click(function () {
var passedID=$(this).attr('data-id');
.
.
?>

如果它有效，那就太好了。如果没有，请按照我的代码一步一步来，它会起作用。

所以，我建议你只为模式制作一页（somepage.php）。使用ajax 以适当方式传递“dataId”的位置。

1) 如下写你的<a></a> 标签。 href="#myModal" 是必填项。

<a class="modalLink" href="#myModal" data-toggle="modal" data-id="<?php echo $obj["service_id"]; ?>">
    <?php echo $obj["service_name"]; ?>
</a>

2) 在页脚中，放置此代码。 （如 footer.php）

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="padding-top: 150px;">
    <div class="modal-dialog">
        <div class="modal-content">

        </div>
    </div>
</div>

3) 通过 ajax 调用您的“somepage.php”（单独的页面。模态正文所在的位置）。将此 <script></script> 放在您的 JS 文件中。

<script>
$('.modalLink').click(function(){
    var dataId=$(this).attr('data-id');
    $.ajax({url:"somepage.php?dataId="+dataId,cache:false,success:function(result){
        $(".modal-content").html(result);
    }});
});
</script>

4) 创建somepage.php（如果你想更改此页面名称。也更改<script></script>。两者都是相关的。）

somepage.php

<?

// Access $dataId like this way and use any where you want in this modal. 

$dataId=$_GET['dataId'];
?>


<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title" id="myModalLabel">Choose your slot</h4>
</div>
<div class="modal-body">
    <input type="text" name="service_id" class="hiddenid" value="<?echo $dataId;?>"/>
    <div class="form-group">
        <table align="center">
            <tr>
                <td colspan="2"> <p class="white_text">Preferred slot 1</p></td>
            </tr>
            <tr>
                <td style="padding-right: 10px;"><input type="date" id="theDate" name="slot1_dt" required> </td>
                <td><input type="time" id="timePicker1" name="slot1_tm" required> </td>
            </tr>
            <tr>
                <td colspan="2" style="padding-top: 15px;"><p class="white_text">Preferred slot 2</p></td>
            </tr>
            <tr>
                <td style="padding-right: 10px;"><input type="date" id="theTomorrow" name="slot2_dt" required> </td>
                <td><input type="time" id="timePicker2" name="slot2_tm" required> </td>
            </tr>
            <tr>
                <td colspan="2" style="padding-top: 15px;">
                    <center><button type="submit" name="book" class="btn btn-default" value="book" style="font-size: 14px !important;">Book</button>
                    &nbsp;
                    <button type="button" class="btn btn-default" style="font-size: 14px !important;" data-dismiss="modal">Close</button></center>
                </td>
            </tr>
        </table>

        <?php
        if(isset($_REQUEST["book"]))
        {
            if($_REQUEST["book"])
            {
                $service_id=$_REQUEST["service_id"];
                $customer_id=$_REQUEST["cust_id"];
                $slot1_dt=$_REQUEST["slot1_dt"];
                $slot2_dt=$_REQUEST["slot2_dt"];
                $slot1_tm=$_REQUEST["slot1_tm"];
                $slot2_tm=$_REQUEST["slot2_tm"];
                $slot1=$slot1_dt." ".$slot1_tm;
                $slot1 = date("Y-m-d H:i:s",strtotime($slot1));
                $slot2=$slot2_dt." ".$slot2_tm;
                $slot2 = date("Y-m-d H:i:s",strtotime($slot2));
                $insertqry="INSERT INTO `tblappointments`(`customer_id`, `service_id`, `preferred_slot1_date`, `preferred_slot2_date`)
                VALUES ('$customer_id','$service_id','$slot1','$slot2')";
                $res=mysqli_query($con, $insertqry) or die(mysqli_error($con));

                if($res)
                {
                    echo("successful.....");
                }
            }
        }
        ?>
    </div>
</div>
<div class="modal-footer">

</div>

享受编码。

更新代码（根据@Sridhar 的要求）

1) 将 href="#" 更改为 href="#myModal" 在您的代码中出现的任何地方以弹出模式。

<td class="bgimg">
  <a href="#myModal" data-id="<?php echo $obj["service_id"]; ?>" data-toggle="modal" data-target="#myModal" class="modalLink">
      <?php echo $obj["service_name"]; ?>
  </a>
</td>

2) 在 JS 中使用此代码。

JS

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script>
$('.modalLink').click(function(){
  var ID=$(this).attr('data-id');
  $.ajax({url:"NewPage.php?ID="+ID,cache:false,success:function(result){
      $(".modal-content").html(result);
  }});
});
</script>

3) 将此代码放在页脚中。

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" style="padding-top: 150px;">
  <div class="modal-dialog">
    <div class="modal-content">

        </div>
    </div>
</div>

4) 创建NewPage.php（如果要更改此页面的页面名称。请在Point-2 <script></script>标签中也更改。两者都是相关的）

NewPage.php

通过_GET 访问ID 并使用此ID 做任何你想做的事情

<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title" id="myModalLabel">Choose your slot</h4>
</div>
<div class="modal-body">
  <?php echo $_GET['ID'];?>
</div>
<div class="modal-footer"></div>
