Question

在这段代码中我使用的是AJAX。我想在td中附加值。我已经为一列添加了值，之后我想追加第二个td的值。我不知道该怎么做。请参阅下面的代码，我在下面的代码中提到了我的要求。 htmlString += '<td>' + 'castename' + '</td>';我想要调用函数castename()。

$(document).ready(function(){
        $("#reservation").on("change", function() {
           var reservation = $(this).val();
              $.ajax({
                  type: 'post',
                  url: 'date-range.php',
                  data: {
                      logindate: reservation,
                  },
                  async : false,
                 success: function(data) {
                  var res = jQuery.parseJSON(data); // convert the json
                  console.log(res);
                  if (res['status'] == "success") {
                    $('#datatable-editable > tbody').empty();//emtpy tbody at the begining
                    $.each(res['data'], function(key, value) {
                      var htmlString = ''; //Place declaration inside each
                      htmlString += '<tr>';
                      var ssm_id = value.ssm_id; // here i got ssmid
                      htmlString += '<td>' + value.ssm_id + '</td>';

                      $.ajax({
                        type: 'post',
                        url: 'config/functions.php',
                        data: {
                          'ssm_id': ssm_id,
                         /* 'caste':ssm_id,
                          'reg_date':ssm_id,
                          'status':ssm_id,
                          'source':ssm_id*/
                        },
                        async : false,
                        success: function(fname) {
                          htmlString += '<td>' + fname + '</td>'; 
                          htmlString += '</tr>';
                          $('#datatable-editable > tbody').append(htmlString);
                        }
                      });


                      $.ajax({
                        type: 'post',
                        url: 'config/functions.php',

                        },
                        async: false,
                        success: function(caste) {
                          htmlString += '<td>' + caste + '</td>'; 
                          htmlString += '</tr>';

似乎你的ajax请求的成功函数是重叠的。

用户Ajax async:false

试试这个： -

$(document).ready(function() {
    $("#reservation").on("change", function() {
        var reservation = $(this).val();
        $.ajax({

            url: 'date-range.php',
