復位文本字段提交

Question

我的代碼不進行重置現場發回什麼：

<script type="text/javascript"> 
     $(function() { 
      $('#ProblemButton').click(function (event) { 
       var form = $('#Form1'); 
       $.ajax({ 

        type: form.attr('method'), 
        url: form.attr('action'), 
        data: $("#reportProblem :input").serialize(), 
        cache: false, 

       }).done(function (data) { 
        $('#reportProblem').modal('hide'); 

        if (data.ResponseType == 0) { 
         $('#SuccessMsg').text('Problem Reported'); 
         $('#SuccessMessage').modal('show'); 

        } 
        else if (data.ResponseType == 1) { 
         $("#SuccessMsg").attr("class", "alert alert-danger"); 
         $('#SuccessMsg').text('Can not report problem'); 
         $('#SuccessMessage').modal('show'); 
        } 

        else { 
         $('#SuccessMsg').text('Data: ' + data.ResponseType + $("#reportProblem :input").serialize()); 
         $('#SuccessMessage').modal('show'); 
        } 
        $('#problemDescription').attr('value', ''); 

        // Optionally alert the user of success here... 


        setTimeout(function() { $('#SuccessMessage').modal('hide'); }, 3000); 


       }).fail(function (jqXHR, textStatus) { 
        // Optionally alert the user of an error here... 
        alert("Error submitting AJAX request" + textStatus); 
       }); 
       event.preventDefault(); // Prevent the form from submitting via the browser. 
      }); 
     }); 

出的內容：

 $('#problemDescription').attr('value', ''); 

的HTML元素是在這裏：

 <asp:TextBox TextMode="MultiLine" ID="problemDescription" Columns="80" Rows="5" runat="server" /> 

Answer 1

你的問題是你錯過了ClientIDMode="Static" becouse控制是ASP.net控制和ID正在改變：

<asp:TextBox TextMode="MultiLine" ID="problemDescription" Columns="80" Rows="5" runat="server" ClientIDMode="Static"/> 

這樣，您可以使用：

$('#problemDescription').val('');
