基于jQuery Ajax的评论列表案例（含表单数据采集）

注：案例用到 bootstrap.css库 和 jquery.js库

  <!-- 评论面板 -->
  <div class="panel panel-primary">
    <div class="panel-heading">
      <h3 class="panel-title">发表评论</h3>

    <form class="panel-body" id="formAddCmt">

      <textarea class="form-control" name="content"></textarea>

      <button type="submit" class="btn btn-primary">发表评论</button>

  <!-- 评论列表 -->
  <ul class="list-group" id="cmt-list">
    <li class="list-group-item">
      <span class="badge" style="background-color: #F0AD4E;">评论时间：</span>
      <span class="badge" style="background-color: #5BC0DE;">评论人：</span>
      Item 1
    </li>
  </ul>

</body>

</html>

cmt.js:

function getCommentList() {
  $.ajax({
    method: 'GET',
    url: 'http://www.liulongbin.top:3006/api/cmtlist',
    success: function (res) {
      if (res.status !== 200) return alert('获取评论列表失败！')
      var rows = []
      $.each(res.data, function (i, item) {
        var str = '<li class="list-group-item"><span class="badge" style="background-color: #F0AD4E;">评论时间：' + item.time + '</span><span class="badge" style="background-color: #5BC0DE;">评论人：' + item.username + '</span>' + item.content + '</li>'
        rows.push(str)
      })
      $('#cmt-list').empty().append(rows.join(''))
    }
  })
}

getCommentList()

$(function () {
  $('#formAddCmt').submit(function (e) {
    e.preventDefault()
    var data = $(this).serialize()
    $.post('http://www.liulongbin.top:3006/api/addcmt', data, function (res) {
      if (res.status !== 201) {
        return alert('发表评论失败！')
      }
      getCommentList()
      $('#formAddCmt')[0].reset()
    })
  })
})
