解析Jquery的LigerUI如何实现文件上传

复制代码 代码如下:

      <div id="AppendBill_Div" style="display:none;">    <%-- 上传 - 单 --%>
          <table style="height:100%;width:100%">
                <tr style="height:40px">
                    <td style="width:20%">
                        图标:
                    </td>
                    <td><input type="file"  style="width:200px" id="fileupload" name="fileupload"/>
                    </td>
                </tr>
          </table>
     </div>

复制代码 代码如下:

      var AppendBillPathDetail = null;
      function f_selectAppendBillPath_1() {
          var imageurl = $("#AppendBill").val();
          var AppendBill_Id = $("#AppendBill").val();  // 单号
          if (imageurl.length == 0) {
              LG.showError("您没有输入单号，请输入随单号！");
              return;
          }
          if (AppendBillPathDetail) {
              AppendBillPathDetail.show();
          }
          else {
              AppendBillPathDetail = $.ligerDialog.open({
                  target: $("#AppendBill_Div"), title: '添加图标',
                  width: 360, height: 170, top: 170, left: 280,  // 弹出窗口大小
                  buttons: [
                      { text: '上传', onclick: function () { AppendBillPath_save(); } },
                      { text: '取消', onclick: function () { AppendBillPathDetail.hide(); } }
                      ]
              });
          }
      }
      function AppendBillPath_save()
      {
           var imgurl = $("#fileupload").val();
           // var filehelpcode = $("#filehelpcode").val();
          var extend = imgurl.substring(imgurl.lastIndexOf("."), imgurl.length);
          extend = extend.toLowerCase();
          if (extend == ".jpg" || extend == ".jpeg" || extend == ".png" || extend == ".gif" || extend == ".bmp")
          {
          }
          else
          {
              LG.showError("请上传jpg,jpep,png,gif,bmp格式的图片文件");
              return;
          }
          var imageurl = $("#AppendBill").val();  // extend
          alert(imageurl);
          $.ajaxFileUpload({
              url: "../handle/ImageUpload.aspx?imageurl=" + imageurl, // --上传-【9】-- aspx文件
              secureuri: false,
              fileElementId: "fileupload", //Input file id
              dataType: "text",
              success: function (data, status)
              {
                  // ----------------- // 保存路径
                 // $("#AppendBillPath2").val(Data);

                  LG.tip(data);
                  f_reload();
              },
              error: function (data, status, e) {
                  LG.showError(data);
              }
          });
      }
