jquery arbeitet mit .NET zusammen, um Click-to-Specify-Bindungsdaten zu realisieren und kann diese mit einem Klick herunterladen

<div id="downloadInfo" runat="server"></div>

// 下载附件的选择
  $attach = $("#download-list");

  $attach.on('click', '.no', function () {
    $(this).toggleClass('checked');//设置和移除，选中与不选中
    if ($(this).hasClass('checked')) {
