javascript - 如何使用javascript将Excel工作簿保存到当前用户桌面？

Question

我通过以下方式从网页创建工作簿:

var thisTable = document.getElementById("mytable3").innerHTML;
       window.clipboardData.setData("Text", thisTable);
       var objExcel = new ActiveXObject ("Excel.Application");
       objExcel.visible = true;
       var objWorkbook = objExcel.Workbooks.Add();
       var objWorksheet = objWorkbook.Worksheets(1);
       objWorkbook.Worksheets(1).Activate;
       objWorksheet.name = "test";
       objWorksheet.Paste;
       objWorksheet.columns.autofit;
       window.clipboardData.setData("Text","");
       objWorkbook.Worksheets(1).SaveAs("%USERPROFILE%\\Desktop\\xxx.xls");

但是对于 objWorkbook.Worksheets(1).SaveAs("%USERPROFILE%\\Desktop\\xxx.xls"); - 它不会保存到桌面并给出以下错误:

SCRIPT1004: Microsoft Excel cannot access the file 'C:\Users\user\Documents\%USERPROFILE%\Desktop\B612F000'. There are several possible reasons:
• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.

来自@PA。回答 我终于得到了答案

//For Expand environment
  var wshShell = new ActiveXObject("WScript.Shell");
  var userProfile = wshShell.ExpandEnvironmentStrings("%USERPROFILE%\\Desktop\\test.xls");

  //For Save
  objWorkbook.Worksheets(1).SaveAs(userProfile);
