<html xmlns="http://www.w3.org/1999/xhtml">

 <!DOCTYPE html>

<script src="../../Scripts/jquery.js" type="text/javascript"></script>

<script type="text/javascript">
    function clearText() 
    {
         document.getElementById('Comment').value = "";

    }
</script>



<script src="../../Scripts/jquery.js" type="text/javascript"></script>
<script type="text/javascript">
 $('#AddCommentButton').click(function () {
 $.ajax({
  type:'post',
  url: '/Comment/SaveComments', //url to your action method
  dataType: 'json',
  data: { 'comments': $('#Comment').val() },
  success: function(data)
  {
      $('#ParentBlock').appendChild("<div>" + data.msg + "</div>");
  }
 });
});

</script>





<script src="../../Scripts/jquery.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $(".ShowComments").click(function () {
            $(".ParentBlock").slideToggle("slow");
            $("CommentP").append(document.getElementById('Comment').value);


        });
    });
</script>





<script src="../../Scripts/jquery.js" type="text/javascript"></script>
<script type="text/javascript">



    $(document).ready(function () {
        $(".ShowComments2").click(function () {
          $(".1").append("<strong>Hello</strong>");
        });
    });


</script>


<style type="text/css"> 
div.ParentBlock
{
position:relative;
display:none;
}

#ClassPara

<body>

    <div class="ParentBlock">



    @foreach (var item in Model)
    {
        <div id="OwnerName">

         <span class="EmpName"> @Html.ActionLink(item.Owner.FullName, "Details", "EMployee", new { id = item.OwnerId }, new { @style = "color:#1A6690;" })</span>

    }



    </div>


   @Html.TextArea("Comment", "", 5, 80, "asdsd")


    <input type="button" value="Add Comment" id="AddCommentButton"/>                         
    <input type="button" value="Clear" onclick="clearText()"/>                    

    <br />




  @*  <label id="AddComment">Add Comment</label>
    <label id="Clear" onclick="clearText()">Clear</label>*@

}


</body>
</html>

怎么做？

Answer 1

点击ADD Comment按钮帖子，对您的操作发表评论，将其保存到数据库或您要保存的位置，然后在ajax的回调函数中返回该评论，以便在页面上显示

$('#addCommentButtonID').click( function() {
 $.ajax({
  type:'post',
  url: 'SaveComments' //url to your action method
  dataType: 'json',
  data: {'comments':$('#textboxId').val()},
  success: function(data)
  {
     $('#yourMainDiv').appendChild("<div>"+data.msg+"</div>");
  }
 });
});

第二种方式：

$('#addCommentButtonID').click( function() {
    $.post('SaveComments',comments:$('#commentTextbox').val(),
        function (data) {
           $('#yourMainDiv').appendChild("<div>"+data.msg+"</div>");
        },'json');
});

你的行动

public JsonResult SaveComments(string comments)
{
   // save it wherever you want
   // after saving success return this string as jsonresult
   return Json(new { sc = true, msg = comment });
}

使用添加的文本，评论功能更新Div
