vb.net jquery datepicker 回发

Question

我在我的项目中使用这个日期选择器 (http://keith-wood.name/datepick.html)

我在 asp:TextBox 控件上使用它，问题是该控件失去了 AutopostBack 功能。

我希望实现的是更新链接到所选日期的网格视图，并且在使用这个特定的日期选择器之前它正在工作（但由于各种原因我不得不更改日期选择器）。

如果我更改日期或从下拉列表中选择用户，它应该更新网格视图。

我的代码的相关部分：

<script language="javascript" type="text/javascript">
    $(document).ready(function () { $('#txtData').datepick({ dateFormat: 'dd/mm/yyyy'});
</script>

以下内容在更新面板中，页面上声明了脚本管理器

<div class="generic">
    <div class="panel">
        <div class="title"><h1>Chiamate del giorno</h1></div>
            <div >
                 <asp:TextBox runat="server" ID="txtData" CssClass="calendarTxt" placeholder="Data" BorderStyle="Solid" BorderColor="#d13f31" BorderWidth="2px" required="required" AutoPostBack="true"></asp:TextBox>

Answer 1

回发可能没有触发，因为控件不知道内容已更改，并且更改事件会导致控件执行回发。

我还没有完全检查插件，但是在 jQuery ui datepicker 中我使用onslect 命令手动执行回调并触发更改事件：

  $('.calendarTxt').datepick({
    onSelect: function (dateText) {
      $(this).trigger('change');
    }
  });

示例

$(document).ready(function () { $('#txtData').datepick({ 
  dateFormat: 'dd/mm/yyyy',
  onSelect: function (dateText) {
    $(this).trigger('change');
  }
});

最后，如果您使用 css 类而不是 id，您可以从主脚本页面触发此代码。这意味着您无需将代码放在每个日期输入控件上，您只需添加类即可。
