使用这个例子：http ://www.w3schools.com/php/php_ajax_database.asp 我已经建立了一个从数据库回显的表。

我现在正在尝试在表上启动数据表插件，一切都设置正确，但它不会工作。我试图在 html 和 php 页面中启动数据表，但似乎都不起作用。

我在合并这个例子时同样有同样的问题：http: //davidwalsh.name/animated-ajax-jquery

是否是第一个示例中的这一点导致问题，因为页面已经在 xmlhttp.open 和 xmlhttp.send() 之前加载；已发送。

 xmlhttp.open("GET","getuser.php?username="+username+"&year="+str,true);
 xmlhttp.send();

      $('a.delete').click(function(e) {
        e.preventDefault();
        var parent = $(this).parent();
        $.ajax({
          type: 'get',
          url: 'jquery-record-delete.php',
          data: 'ajax=1&delete=' + parent.attr('id').replace('record-',''),
          beforeSend: function() {
            parent.animate({'backgroundColor':'#fb6c6c'},300);
          },
          success: function() {
            parent.slideUp(300,function() {
              parent.remove();
            });
          }
        });
      });
    });

        jQuery( function( $ ) {// Implements the dataTables plugin on the HTML table
var $adtTable= $("#academic_days_table").dataTable({

在 xmlhttp.onreadystatechange=function() 中包含脚本

数据表现在已加载并且 $('a.delete').click(function(e) {} 正在工作

这是一个例子：

 function showUser(str, username)
 {
 if (str=="")
   {
   document.getElementById("department_logs_txtHint").innerHTML="";
   return;
   } 
 if (window.XMLHttpRequest)
   {// code for IE7+, Firefox, Chrome, Opera, Safari
   xmlhttp=new XMLHttpRequest();
   }
 else
   {// code for IE6, IE5
   xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
   }
 xmlhttp.onreadystatechange=function()
   {
   if (xmlhttp.readyState==4 && xmlhttp.status==200)
     {           
     document.getElementById("department_logs_txtHint").innerHTML=xmlhttp.responseText;
     $('#business_days_table').dataTable({
        "iDisplayLength": 30,       
        "sDom": '<"clear">t>',
        "aaSortingFixed": [[0,'asc']],
        "aoColumns": [
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false }
            ]
     });    
     $('#academic_days_table').dataTable({
        "iDisplayLength": 30,       
        "sDom": '<"clear">t>',
        "aaSortingFixed": [[0,'asc']],
        "aoColumns": [
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false },
            { "bSortable": false }
            ]
     });
  $('a.delete').click(function(e) {
    e.preventDefault();
    var parent = $(this).parent();
    $.ajax({
      type: 'get',
      url: 'getuser.php',
      data: 'ajax=1&delete=' + parent.attr('id').replace('record-',''),
      beforeSend: function() {
        parent.animate({'backgroundColor':'#fb6c6c'},300);
      },
      success: function() {
        parent.slideUp(300,function() {
          parent.remove();
        });
      }
    });
  });

     }
   }

 xmlhttp.open("GET","getuser.php?username="+username+"&year="+str,true);
 xmlhttp.send();
 }
