还是WebBrowser打印

还是WebBrowser打印

打印是一个头痛的问题.
AxtiveX控件收费,用户使用需降低安全级别.
最后还是打算用webBrowser打印.

1.js

/**/ /*
*设置页眉和页脚
*/
function  setPageHF(isSet)
{
    try
    { 
        var regWriteShell = new ActiveXObject("WScript.Shell");
        var regKey="HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";
        if(isSet)
        {
            //设置
            regWriteShell.RegWrite(regKey+"header","");
            regWriteShell.RegWrite(regKey+"footer","&b科印传媒 第&p页 共&P页");
            //regWriteShell.RegWrite(regKey+"footer","");
        }
        else
        { 
            //清除
            regWriteShell.RegWrite(regKey+"header","");
            regWriteShell.RegWrite(regKey+"footer","");
        }
    }catch(e){} 
}

/**/ /*
*要完成打印的必须信息
*/
function  writeInfo()
{
    //对象信息
    var objInfo = "<object id='WebBrowser' width=0 height=0 classid='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'></object>";
    document.write(objInfo);
    
    //相关CSS
    var cssInfo = "<style media='print'>";
    cssInfo += ".noPrint{display:none;background-color:#939392;}";
    cssInfo += ".nextPage{page-break-after: always;}";
    cssInfo += "</style>";
    //document.write(cssInfo);
}

/**/ /*
*打印
*/
function  print()
{
    document.all.WebBrowser.Execwb(6,1);
}

/**/ /*
*直接打印
*/
function  printDirect ()
{
    document.all.WebBrowser.ExecWB(6,6);
}

/**/ /*
*打印预览
*/
function  printView()
{
    document.all.WebBrowser.ExecWB(7,1);
}

/**/ /*
*打印设置
*/
function  printSet()
{
    document.all.WebBrowser.ExecWB(8,1);
}

2.table html
   1).第个打印页有表头
   2).每页表格线连续

StringBuffer printPageStr  =   new  StringBuffer();
         //  当前页DIV
        printPageStr.append( " <div id=\ " page " ).append(currentPage).append( " \ "  class='nextPage'> " );
        printPageStr.append( " <table id=\ " table_1 " );
        printPageStr.append( " \ "  width = \ " 100%\ "   class = \ " tabp\ "   cellpadding = ' 2 '  cellspacing = ' 0 ' > " );
         //  表头
        printPageStr.append( " <tr> " );
        printPageStr.append( " <thead style='display:table-header-group;font-weight:bold;'> " );
        
         for  (Object headerName : baseInfoHeadLst)
         {
            printPageStr.append("<th nowrap=\"nowrap\"  class='thp' style='border-top:1px solid #000000;'>");
            printPageStr.append(headerName == null ? "" : headerName);
            printPageStr.append("</th>");
        }
        printPageStr.append( " </thead></tr> " );
         //  表体
         for (List innerLst : dataLst)
         {
            printPageStr.append("<tr>");
            for(Object data : innerLst)
            {
                printPageStr.append("<td nowrap=\"nowrap\" class='tdp'>");
                printPageStr.append(data == null ? "" : data).append("&nbsp");
                printPageStr.append("</td>");
            }
            printPageStr.append("</tr>");
        }
        printPageStr.append( " </table> " );
        
        printPageStr.append( " <br/> " );
        printPageStr.append( " </div> " );
         return  printPageStr.toString();
