發送特定數據到ajax

Question

我想將可變數據發布到ajax發布這是我的html代碼

 <tr> <td class="text-right">Payment ID:</td> <td>variable</td> // variable that i want to post </tr> 

這是我的Java腳本代碼

 var ajax_call = function() { $.ajax({ type:"post", url:"request-handler.php", data:{ data:"Payment ID" } }); }; var interval = 5000; // where X is your every X minutes setInterval(ajax_call, interval); 

現在我想在ajaxpost中的td標簽之間發布變量

Answer 1

在該單元格上設置一個id，以便您的js易於閱讀，然后只需使用jQuery即可訪問文本。

 var ajax_call = function() { $.ajax({ type: "post", url: "request-handler.php", data: { paymentId: $('#payment-id').text(); // access this on the php server using: $_POST['paymentId']; } }); }; var interval = 5000; // where X is your every X minutes setInterval(ajax_call, interval); 

 <tr> <td class="text-right">Payment ID:</td> <td id="payment-id">variable</td> <!-- variable that i want to post --> </tr> 

Answer 2

<tr id="rowID">
  <td class="text-right">Payment ID:</td>
  <td>variable</td> // variable that i want to post
</tr>

並在您的javascript中

var ajax_call = function() {
      $.ajax({
           type:"post",
           url:"request-handler.php",
           data:{
                    var Row = document.getElementById("rowID");
var Cells = Row.getElementsByTagName("td");
                    data:Cells[1].innerText

                    }
                });


};

編輯：您可以直接使用var cells = document。 getElementsByTagName （“ td”）; 也一樣 或將ID和ID設置為單元格<tr > <td class="text-right">Payment ID:</td> <td id="columnID">variable</td> // variable that i want to post </tr>

data:{document.getElementById("columnID")}
