在我的网络中有一些表格内容，我给出了这样的静态值

         </td>
    </tr>
</table>

<div class="popup_window_css_foot">

然后我使用 jquery 选择器来获取该值并使用 ajax 像这样执行该值

 var htmlobjek;
     $(document).ready(function () {
         var i = $("td").find("td.data").val();
          $.ajax({
                 url: "cek.php",
                 data: "i",
                 cache: false,
                 success: function (data) {
                     $("#cek").val(data);
                 }
             });     
     });

在 cek.php 中当然是这样的

<?php
$posisi =  $_POST[i];

$val = mssql_num_rows(mssql_query("SELECT*FROM tblTrnProduct WHERE Posisi = '$posisi'"));

echo"$val";
?>

根据之前的答案，是的，它有效。但在单表中。我检查了我的 html 结构（没关系）。在我修改成复杂表后，同样的情况再次发生。

试试这个，希望有用

 var j = $("td").find("td.data").val(); //make sure this will returning value 
 $.ajax({
      url: "cek.php",
      type:"POST",
      data: { i: j },  //Or try { i: $("td").find("td.data").val()},  
      cache: false,
      success: function (data) {
          $("#cek").val(data);
      }
 });

在php中

$posisi =  $_POST['i'];

示例表单jQuery 网站

  $.post("test.php", { name: "John", time: "2pm" })
    .done(function(data) {
      alert("Data Loaded: " + data);
    });

在<td class="data">你忘记</tr>.

$(document).ready(function(){

    function setvalue(values) {
        $('#posisi').val(values);
    }

    var htmlobjek;
    //apabila terjadi event onchange terhadap object <select id=pid>
    $("#pid").change(function(){
        var pid = $("#pid").val();
        $.ajax({
            url: "ambilnamaproduk.php",
            data: "pid="+pid,
            cache: false,
            success: function(data){
                $("#pname").val(data);
            }
        });
    });

    var i = $("tr").find("td.data").attr('value');
    $.ajax({
         url: "cek.php",
         type:'POST'
         data: {"data": i},
         cache: false,
         success: 
         function (data) {
             $("#cek").val(data);
         }
    });

    var k = $("#cek").val();
    if(k = "0"){
        $(".data").css("background-color", "#00CC00");//green
    }
    else {
        $(".data").css("background-color", "#FF0000");//red
    }

});

在 cek.php 你的 'i' 应该是可用的$_POST['data']。

仅供参考：如果您有多个带有值的行，或者在这些表的行中有多个带有值的表，您应该编写不同的代码。请看这个 jsFiddle。

但是，如果有很多值，就会有很多 ajax 调用。更好的解决方案是将值添加到隐藏输入中。请看这个 jsFiddle。

希望对你有所帮助。

首先尝试解决这个问题：

var i = $("td").find("td.data").val();
...
data: "i",

到

var i = $("td").find(".data").attr('value');
...
data: "i="+i,

试试这个=

$.ajax({
                 url: "cek.php",
                 data: { "data": i},
                 cache: false,
                 success: function (data) {
                     $("#cek").val(data);
                 }
             });

在 php 中，您可以执行以下操作：

$data = $_POST['data']; //you will get your value

您的 javascript 函数有两个主要问题 1) 您的变量

data: "i",

应该

data: i,

2）其次，您没有提到 ajax 方法的类型，无论是 GET 还是 POST，在 AJAX 中，如果您不提及，默认类型将是 GET。因此，在您的情况下，您传递的类型是 GET 并尝试以 POST 的形式访问变量。所以将此行添加到您的 AJAX 调用中

type:'POST',
