如何将隐藏字段中的变量发送到远程PHP文件,并在不使用jQuery刷新的情况下在Bootstrap模式中显示脚本的结果?

我在一个生成dinamically的表中有以下表单:

文件index.php

session_start();

...

<table>
    <tr>
        <td>Name</td>
        <td>Band</td>
        <td>Indx</td>
        <td>Send</td>
    </tr>
    <tr>
        <td>Bruce</td>
        <td>Iron Maiden</td>
        <td>95</td>
        <td>
            <form action="remote.php" class="rock" method="POST">
                <input class="name" name="name" type="hidden" value="Bruce">
                <input class="band" name="band" type="hidden" value="Iron Maiden">
                <input class="indx" name="indx" type="hidden" value="95">
                <button class ="send" type="submit">SEND<button>
            </form>
        </td>
    </tr>
    <tr>
        <td>James</td>
        <td>Metallica</td>
        <td>90</td>
        <td>
            <form action="remote.php" class="rock" method="POST">
                <input class="name" name="name" type="hidden" value="James">
                <input class="band" name="band" type="hidden" value="Metallica">
                <input class="inx" name="indx" type="hidden" value="90">
                <button class ="send" type="submit">SEND<button>
            </form>
        </td>
    </tr>

当我点击发送时,它会将信息发送到remote.php上的脚本:

文件remote.php

<?php

    session_start();

    $name = $_POST['name'];
    $band = $_POST['band'];
    $indx = $_POST['indx'];

    $up = $indx * 2;

    $output = '
        <div id="rock-modal" class="modal fade in" role="dialog" tabindex="-1" aria-labelledby="myLargeModalLabel" aria-hidden="true">
            <div class="modal-dialog modal-lg">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                        <h4 class="modal-title" id="myModalLabel">
                            <i class="fa fa-files-o"></i>
                            Rock Modal
                        </h4>
                    </div>
                    <div class="modal-body">
                        The band '.$band.' has an up index of '.$up.'!';
                    </div><!-- /modal-body -->
                </div><!-- /modal-content -->
            </div><!-- /modal-dialog modal-lg -->
        </div><!-- /modal fade in-->';

    $_SESSION['output'] = $output;

    header('Location: index.php');

然后index.php是新加载的,但现在它打开一个模式框,其中包含来自remote.php的输出:

<table>
...
</table>

if(isset($output){
    echo $output;
}

<script type="text/javascript">
    // Compare Modal
    $('#rock-modal').modal('show');
</script>

但是现在我想做同样的事情,但没有页面重新加载,即使用jQuery。

我做了一些研究,并在StackOverflow(How to display dynamical content from a remote file in bootstrap modal using php?)中使用另一种方法提出问题,以获取有关它的更多信息。有了这个有价值的信息,我做了以下几点:

    <tr>
        <td>Bruce</td>
        <td>Iron Maiden</td>
        <td>95</td>
        <td>
            <form action="remote.php" class="rock" method="POST">
                <input class="name" name="name" type="hidden" value="James">
                <input class="band" name="band" type="hidden" value="Metallica">
                <input class="inx" name="indx" type="hidden" value="90">
            </form>

            <a class="btn btn-info rock-send" data-modal="#rock-modal" data-href="remote.php">OK</a>
        </td>
    </tr>

$(function() {
    $('.rock-send').on('click', function() {
        var data = $(this).closest('tr').find('>td:lt(3)'),
        modal = $(this).data('modal');
        $.post( $(this).data('href'), {
            name: data.name.text(),
            band: data.band.text(),
            indx: data.indx.text(),
        }, function( data ) {
            $(modal).modal('show');
        });
    });
});

但不知怎的,它不起作用。我不确定remote.php是否可以读取已发送的变量并将其返回。我该如何管理它? 这可能是javascript中的一个问题。我将不胜感激任何帮助! 提前谢谢。

这里是index.php的代码,基于评论。

            <td>
                <form action="remote.php" class="rock" method="POST">
                    <input class="name" name="name" type="hidden" value="James">
                    <input class="band" name="band" type="hidden" value="Metallica">

                <a class="btn btn-info rock-send" data-modal="#rock-modal" data-href="remote.php">OK</a>
            </td>
        </tr>
    </table>

    <script src="https://code.jquery.com/jquery-1.11.1.js"></script>
    <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

    <script>
        $(function() {
            $('.rock-send').on('click', function() {

                var name = $("input[name='name']").val();
                var band = $("input[name='band']").val();
                var indx = $("input[name='indx']").val();
                $.post('remote.php', {
                    name: name,
                    band: band,
                    indx: indx,
                }, function( data ) {
                    $("#rock-modal").html(data);
                    $("#rock-modal").modal('show');
                });
            });
        });
    </script>
</body>
</html>

这里是完整的remote.php

<?php
    $name = $_POST['name'];
    $band = $_POST['band'];
    $indx = $_POST['indx'];
    $up = $indx * 2;

    $output = '
        <div id="rock-modal" class="modal fade in" role="dialog" tabindex="-1" aria-labelledby="myLargeModalLabel" aria-hidden="true">
            <div class="modal-dialog modal-lg">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                        <h4 class="modal-title" id="myModalLabel">
                            <i class="fa fa-files-o"></i>
                            Rock Modal
                        </h4>
                    </div>
                    <div class="modal-body">
                        The band '.$band.' has an up index of '.$up.'!!!
                    </div><!-- /modal-body -->
                </div><!-- /modal-content -->
            </div><!-- /modal-dialog modal-lg -->
        </div><!-- /modal fade in-->';
    echo $output;

但不幸的是没有任何事情发生。 : - \

试试这个,

$(function() {
   $('.rock-send').on('click', function() {

    var name = $("input[name='name']").val();
    var band = $("input[name='band']").val();
    var indx = $("input[name='indx']").val();
    $.post('remote.php', { // dont forget to change the remote url there
        name: name,
        band: band,
        indx: indx,
    }, function( data ) {
        $("#rock-modal").html(data); // data is response from your remote php srcipt
                                     // so set this data to div with id "rock-modal"
        $("#rock-modal").modal('show'); // and show the div with id rock-modal
    });
  });
});

以下是一些可以帮助您解决此问题的建议:

  • 模态标记(HTML)属于主页index.php
  • 如果您希望remote.php返回多个值,请返回JSON
  • 总是更好地倾听表单的submit事件,而不是click事件。
  • 一定要包含jQuery和Bootstrap(js&amp; css)
  • BONUS remote.php正在执行的处理(如果他们正在做的事情)实际上可以使用客户端上的JavaScript执行 - 这意味着您不需要提交表单,而且您不需要remote.php

您的JavaScript应该是:

$(document).ready(function(){
    $('.rock').on('submit', function( e ){
        e.preventDefault();
        var band = $(this).find('input[name=band]').val(),
            indx = +$(this).find('input[name=indx]').val(),
            up = indx * 2;
        $('#rock-modal').find('.modal-body')
        .text( 'The band ' + band + ' has an up index of ' + up + '!!!' ).end()
        .modal('show');
     });
});
