Js操作Excel常用方法

Js操作Excel常用方法

1.创建一个新Excel表格

    var XLObj = new ActiveXObject("Excel.Application");
    var xlBook = XLObj.Workbooks.Add;                         //新增工作簿
    var ExcelSheet = xlBook.Worksheets(1);                   //创建工作表

2.保存表格

   var fileDialog =  XLObj.FileDialog(2); //1.打开  2.保存
   fileDialog.show();  
   var savePath = fileDialog.SelectedItems(1);
    ExcelSheet.SaveAs(savePath);
    ExcelSheet.SaveAs("C:\\TEST.XLS");

3.使 Excel 通过Application 对象可见
    ExcelSheet.Application.Visible = true;

4.打印
    xlBook.PrintOut;
    或者:
    ExcelSheet.PrintOut;

5.关闭
    xlBook.Close(savechanges=false);
    或者:
    ExcelSheet.Close(savechanges=false);

6.结束进程
    ExcelSheet.Application.Quit();
    或者:
    XLObj.Quit();
    XLObj=null;

function endXlsObj(){    
    oXL.UserControl = true;   
    oXL=null;   
    oWB=null;   
    activeSheet=null;   
    //结束excel进程，退出完成
    idTmr = window.setInterval("Cleanup();",1);
}
function Cleanup() {
    window.clearInterval(idTmr);
    CollectGarbage();
} 

7.页面设置

    ExcelSheet.ActiveSheet.PageSetup.Orientation = 2;
    ExcelSheet.ActiveSheet.PageSetup.LeftMargin= 2/0.035;         //页边距 左2厘米
    ExcelSheet.ActiveSheet.PageSetup.RightMargin = 3/0.035;      //页边距 右3厘米，
    ExcelSheet.ActiveSheet.PageSetup.TopMargin = 4/0.035;        //页边距 上4厘米，
    ExcelSheet.ActiveSheet.PageSetup.BottomMargin = 5/0.035;   //页边距 下5厘米
    ExcelSheet.ActiveSheet.PageSetup.HeaderMargin = 1/0.035;   //页边距 页眉1厘米
    ExcelSheet.ActiveSheet.PageSetup.FooterMargin = 2/0.035;    //页边距 页脚2厘米
    ExcelSheet.ActiveSheet.PageSetup.CenterHeader = "页眉中部内容";
    ExcelSheet.ActiveSheet.PageSetup.LeftHeader = "页眉左部内容";
    ExcelSheet.ActiveSheet.PageSetup.RightHeader = "页眉右部内容";
    ExcelSheet.ActiveSheet.PageSetup.LeftFooter = "页脚左部内容";
    ExcelSheet.ActiveSheet.PageSetup.RightFooter = "页脚右部内容";            

    ExcelSheet.ActiveSheet.PageSetup.CenterHeader = "&\"宋体,加粗\"&18长天公司" + date1 + "至" + date2 + "(施工图)项目进度检查表";
    ExcelSheet.ActiveSheet.PageSetup.RightHeader = "&D";
    ExcelSheet.ActiveSheet.PageSetup.PrintGridlines = true;
    ExcelSheet.ActiveSheet.PageSetup.PrintTitleRows = "$1:$1";
    ExcelSheet.ActiveSheet.PageSetup.Zoom = 75;

8.对单元格操作，带*部分对于行，列，区域都有相应属性
    ExcelSheet.ActiveSheet.Cells(row,col).Value = "内容";                //设置单元格内容
    ExcelSheet.ActiveSheet.Cells(row,col).Borders.Weight = 1;        //设置单元格边框*()
    ExcelSheet.ActiveSheet.Cells(row,col).Interior.ColorIndex = 1;    //设置单元格底色*(1-黑色，
        2-白色，3-红色，4-绿色，5-蓝色，6-黄色，7-粉红色，8-天蓝色，9-酱土色..可以多做尝试)
    ExcelSheet.ActiveSheet.Cells(row,col).Interior.Pattern = 1;         //设置单元格背景样式*(1-无，
                                                     2-细网格，3-粗网格，4-斑点，5-横线，6-竖线..可以多做尝试)
    ExcelSheet.ActiveSheet.Cells(row,col).Font.ColorIndex = 1;        //设置字体颜色*(与上相同)
    ExcelSheet.ActiveSheet.Cells(row,col).Font.Size = 10;                //设置为10号字*
    ExcelSheet.ActiveSheet.Cells(row,col).Font.Name = "黑体";        //设置为黑体*
    ExcelSheet.ActiveSheet.Cells(row,col).Font.Italic = true;             //设置为斜体*
    ExcelSheet.ActiveSheet.Cells(row,col).Font.Bold = true;             //设置为粗体*
    ExcelSheet.ActiveSheet.Cells(row,col).ClearContents;                //清除内容*
    ExcelSheet.ActiveSheet.Cells(row,col).WrapText=true;               //设置为自动换行*
    ExcelSheet.ActiveSheet.Cells(row,col).HorizontalAlignment = 3; //水平对齐方式枚举* (1-常规，
                                    2-靠左，3-居中，4-靠右，5-填充 6-两端对齐，7-跨列居中，8-分散对齐)
    ExcelSheet.ActiveSheet.Cells(row,col).VerticalAlignment = 2;      //垂直对齐方式枚举*(1-靠上，
                                                                                  2-居中，3-靠下，4-两端对齐，5-分散对齐)
    //行，列有相应操作:
    ExcelSheet.ActiveSheet.Rows(row).
    ExcelSheet.ActiveSheet.Columns(col).
    ExcelSheet.ActiveSheet.Rows(startrow+":"+endrow).                  //如Rows("1:5")即1到5行
    ExcelSheet.ActiveSheet.Columns(startcol+":"+endcol).               //如Columns("1:5")即1到5列
    //区域有相应操作:
    XLObj.Range(startcell+":"+endcell).Select;
        //如Range("A2:H8")即A列第2格至H列第8格的整个区域
    XLObj.Selection.
    //合并单元格
    XLObj.Range(startcell+":"+endcell).MergeCells = true;
        //如Range("A2:H8")即将A列第2格至H列第8格的整个区域合并为一个单元格
    或者:
    XLObj.Range("A2",XLObj.Cells(8, 8)).MergeCells = true;

9.设置行高与列宽
    ExcelSheet.ActiveSheet.Columns(startcol+":"+endcol).ColumnWidth = 22;
        //设置从firstcol到stopcol列的宽度为22
    ExcelSheet.ActiveSheet.Rows(startrow+":"+endrow).RowHeight = 22;
        //设置从firstrow到stoprow行的宽度为22
