  47. </style>
  48. </head>
  49. <body>
  50. <table>
  51. <caption>
  52. 员工信息表
  53. </caption>
  54. <thead>
  55. <tr>
  56. <th>id</th>
  57. <th>姓名</th>
  58. <th>年龄</th>

  61. <th>手机号</th>
  62. </tr>
  63. </thead>
  64. <tbody></tbody>
  65. </table>
  66. <!-- 分页条 -->
  67. <p></p>
  68. </body>
  69. <script>
  70. // 默认是第1页
  71. var page = 1;
  72. // 默认显示第一页,用一个函数来实现显示
  73. getPageData(page);
  74. // 分页函数
  75. function getPageData(page) {
  76. // ajax无刷新分页
  77. $.ajax({
  78. type: "post",
  79. url: "page_data.php",
  80. data: { page: page },
  81. dataType: "json",
  82. success: show,
  83. });
  84. }
  85. // 数据显示函数
  86. function show(data) {
  87. // 1. 显示表格数据
  88. var str = "";
  89. data.staffs.forEach(function (staff) {
  90. str += "<tr>";
  91. str += "<td>" + staff.id + "</td>";
  92. str += "<td><input type='text' value=" + staff.name + "></td>";
  93. str += "<td>" + staff.age + "</td>";
  94. str += "<td>" + staff.sex + "</td>";
  95. str += "<td>" + staff.position + "</td>";
  96. str += "<td>" + staff.mobile + "</td>";
  97. str += "</tr>";
  98. });
  99. $("tbody").html(str);
  100. // 2. 显示分页条
  101. var str = "";
  102. for (var i = 1; i <= data.pages; i++) {
  103. str += '<a href="" data-index=' + i + ">" + i + "</a> ";
  104. }
  105. // 将页码添到分页条, 并将当前页置为高亮
  106. $("p")
  107. .html(str)
  108. .find("a")
  109. .eq(page - 1)
  110. .addClass("active");
  111. // 分页条的点击事件
  112. $("p a").click(function (ev) {
  113. // 禁用<a>的跳转默认行为
  114. ev.preventDefault();
  115. page = $(this).attr("data-index");
  116. $("tbody").html("");
  117. getPageData(page);
  118. });
  119. }
  120. </script>
  121. </html>

效果图如下:

总结:
1、Ajax应用,按照老师归纳的步骤,实现起来比较优雅。
2、还需要多学、多记、多练,避免记混。
3、两个月的时间,大量的语法、丰富的函数,众多的案例,对全栈工作有了初步的认知。感谢朱老师的无私讲授、辛勤付出!
