Javascript 单击时通过JQuery传递给PHP脚本的表值

我在数据表中有一个链接，可以打开引导模式。在模态中，我有一个morris.js图。我不知道如何根据用户单击的链接过滤数据集

如何读入单击位置的值，例如本例中的Cluster1或Cluster2。将该变量传递给数据拉取脚本，例如cluster_pulse.php，然后传递到该脚本中的SQL查询中

谢谢

桌子的剪子：

<tr class="odd">
<td class="sorting_1">
<a href="#" data-toggle="modal" data-target="#clusterpulse">Cluster1</a></td>...
<a href="#" data-toggle="modal" data-target="#clusterpulse">Cluster2</a></td>...

模式：

<div class="modal fade" id="clusterpulse" tabindex="-1" role="dialog"
                aria-labelledby="clusterpulse" 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">Cluster Pulse</h4>
         </div>
         <div class="modal-body">  
         <div class="panel panel-primary">
         <div class="panel-heading">
            <h3 class="panel-title"><i class="fa fa-long-arrow-right"></i>Cluster Pulse</h3>
         </div>
         <div class="panel-body">
         <div id="morris-chart-cluster-pulse"></div>
         </div>
        </div>
        </div>
         </div>
       </div>
     </div>

js：

<script> 
        $('#clusterpulse').on('shown.bs.modal', function () {
            $(function () {
            $( "#morris-chart-cluster-pulse" ).empty();

            // Create a Bar Chart with Morris
            var chart = Morris.Line({
                element: 'morris-chart-cluster-pulse',

                d: [
                    { d: '0', VSI: 0 }
                  ],
                  xkey: 'd',
                  ykeys: ['test'],
                  labels: ['test'],
                gridIntegers: true,
                  ymax: '1',
                  ymin: '0',
                  xLabelFormat: function(d) { return (d.getMonth()+1)+'/'+d.getDate();},
                  xLabels: "week"

            });

            // Fire off an AJAX request to load the data
            $.ajax({
                type: "GET",
                dataType: 'json',
                url: "../scripts/cluster_pulse.php", // This is the URL to the API

            })
                .done(function (data) {
                    // When the response to the AJAX request comes back render the chart with new data
                    chart.setData(data);
                })
                .fail(function () {
                    // If there is no communication between the server, show an error
                    alert("error occured");
                });
        });
        });

数据拉脚本：

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

if( $conn === false ) {
echo "Could not connect.\n";
die( print_r( sqlsrv_errors(), true));
}
/* Set up and execute the query. */
$sql = "SELECT d,test FROM <database> WHERE CLUSTER_NAME = '%$value%'
";
$stmt = sqlsrv_query( $conn, $sql);

do {
 while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
 $json[] = $row;

 }
} while ( sqlsrv_next_result($stmt) );
foreach($json as &$each) {
// reassign "d" key to just the date (formatted), discard the rest
$each['d'] = date('Y-m-d', strtotime($each['d']));
}
echo json_encode($json);
?>

以下示例的HTML我不知道您的表是否存在问题：

<a href='#' data-toggle='modal' data-target='#clusterpulse' id='cluster_number_1'>Cluster1</a>
<a href="#" data-toggle='modal' data-target='#clusterpulse' id='cluster_number_2'>Cluster2</a>

您可以在../scripts/cluster_pulse.php获得AJAX，如下所示：

现在从内部

.done(function(results){
  /* result are now JSON with properties like:
    {
      'cluster1':'Cluster1',
      'extra_data':'some other data here 1';
    }
    or
    {
      'cluster2':'Cluster1',
      'extra_data':'some other data here 2';
    }
    Note:
      There is probably no need to send results already available in JavaScript to the
      Server only to get them back to pass the results into your `.done()` method's
      function argument
   $('#outputId1').html(results.cluster1);
  */
});

我最后做的是向表对象添加一个ID，并使用集群名称：

...
<td class="sorting_1">
<a href="#" data-toggle="modal" data-target="#clusterpulse" id="cluster1">cluster1</a></td>
...

然后在get中，我将ID传递给API：

$.ajax({
type: "GET",
dataType: 'json',
url: "../scripts/cluster_pulse.php?val="+id, // This is the URL to the API

然后在php中，我抓取变量并将其传递到查询中：

$rec = $_REQUEST['val'];
...
$sql = "SELECT d,test FROM <database> WHERE CLUSTER_NAME = ('".$rec."')";

它似乎工作得很好。感谢所有帮助。

您可以在函数中获取处理单击事件的参数，然后获取所需的属性。F.E.：$'clusterpulse'。在'Showed.bs.modal'上，函数E{then var anchorText=$E.target.text；是否有任何方法使其更具动态性？我可能会在表中随机设置一些群集，因此我不想静态分配。谢谢。

$("table").delegate("a", "click", function() {
id=$(this).attr('id');
}); 

$.ajax({
type: "GET",
dataType: 'json',
url: "../scripts/cluster_pulse.php?val="+id, // This is the URL to the API

$rec = $_REQUEST['val'];
...
$sql = "SELECT d,test FROM <database> WHERE CLUSTER_NAME = ('".$rec."')";
