IE直接打印
////以下脚本实现:打印指定的datagridvar vGridContent; //DataGrid的内容
var vHeaderInfo; //打印的表头
var vTailerInfo; //打印的表尾
/*
目的:在页面写入隐藏帧并打印
参数:
vDataGrid 所要打印的DataGrid句柄
备注:
代码中调用如下
btPrint.Attributes.Add("onclick","return PrintDataGrid(document.all('SheetList'))");
SheetList为待打印的DataGrid的ID
*/
function PrintDataGrid(vDataGrid)
{
PickupHeaderInfo();
document.body.insertAdjacentHTML("beforeEnd",
"<iframe name=printHiddenFrame width=0 height=0></iframe>");
问题一:“insertAdjacentHTML”是个什么函数?起了怎样的作用???
var doc = printHiddenFrame.document;
doc.open();
doc.write("<body onload=\"setTimeout('parent.onprintHiddenFrame()', 0)\">");
问题二:“<body onload=\"setTimeout('parent.onprintHiddenFrame()', 0)\">”有什么作用???
doc.write("<iframe name=printMe width=0 height=0 ></iframe>");
doc.write("</body>");
doc.close();
CreateHtmlReport(printHiddenFrame.printMe,vDataGrid);
return false;
}
/*
目的:在隐藏帧中写入DataGrid的内容,并重写DataGrid的格式
参数:
vHideFrame 隐藏帧的句柄
vDataGrid 所要打印的DataGrid句柄
备注:
*/
function CreateHtmlReport(vHideFrame,vDataGrid)
{
vGridContent = vDataGrid.outerHTML;
问题三:这一句什么作用???
// 输出报表头信息及抽取过来的表格
var doc = vHideFrame.document;
doc.open();
doc.write("<html><body>");
doc.write(vHeaderInfo);
doc.write(vGridContent);
doc.write("</body></html>");
doc.close();
// 重新设置表格样式
vDataGrid.borderColor = "#000000";
vDataGrid.width = "100%";
vDataGrid.style.fontFamily = "Verdana";
vDataGrid.style.fontSize = "12px";
vDataGrid.style.borderRight = "2px solid #000000";
vDataGrid.style.borderTop = "2px solid #000000";
vDataGrid.style.borderLeft = "2px solid #000000";
vDataGrid.style.borderBottom = "2px solid #000000";
vDataGrid.style.borderCollapse = "collapse";
// 重新设置表格头样式
var TBody = vDataGrid.children(0);
TBody.children(0).style.fontWeight = "bold";
TBody.children(0).bgColor = "#E7E7E7";
// 替换原表格底部的页码信息
var pageInfo = "<td>第 " + ((4 - 3) / 1 + 1) + " 页 / 共 " + "1" + " 页 </td>";
}
//创建表头 表尾
function PickupHeaderInfo()
{
try
{
// 提取报表标题字体大小
var ReportTitleWithSizeInfo = "<font size='" + "+2" + "'>" + "无费用用户统计" + "</font>"
var reportDate = "";
var reportWriter = "";
var nowdate=new Date();
reportDate = "<b>统计时间</b>:" +nowdate.toLocaleString() + "<br>";
reportDate +="<b>营业厅</b>:测试而已<br>";
// 生成报表头信息
vHeaderInfo = "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=gb2312\">";
vHeaderInfo += "<title>无费用用户统计</title></head>" +
"<body bgcolor='#FFFFFF' style='color: #000000; font-family: Verdana; font-size:12px; cursor: default'>";
vHeaderInfo += "<br><p align='center'><b>" + ReportTitleWithSizeInfo + "</b></p>";
vHeaderInfo += "<p>" + reportDate;
vHeaderInfo += reportWriter + "</p>";
}
catch (e)
{
alert("提取报表公共信息失败,打印操作被取消!");
self.close();
}
}
问题四:如果不需要自定样式这里应该怎样修改,直接删除就可以了???
//下面的脚本来自msdn
// The code by Captain <cerebrum@iname.com>
// Mead & Company, http://www.meadroid.com/wpm/
// fake print() for IE4.x
if ( !printIsNativeSupport() )
window.print = printFrame;
// main stuff
function printFrame(frame, onfinish) {
if ( !frame ) frame = window;
if ( frame.document.readyState !== "complete" &&
!confirm("The document to print is not downloaded yet! Continue with printing?") )
{
if ( onfinish ) onfinish();
return;
}
if ( printIsNativeSupport() ) {
/* focus handling for this scope is IE5Beta workaround,
should be gone with IE5 RTM.
*/
var focused = document.activeElement;
frame.focus();
frame.self.print();
if ( onfinish ) onfinish();
if ( focused && !focused.disabled ) focused.focus();
return;
}
var eventScope = printGetEventScope(frame);
var focused = document.activeElement;
window.printHelper = function() {
execScript("on error resume next: printWB.ExecWB 6, 1", "VBScript");
printFireEvent(frame, eventScope, "onafterprint");
printWB.outerHTML = "";
if ( onfinish ) onfinish();
if ( focused && !focused.disabled ) focused.focus();
window.printHelper = null;
}
document.body.insertAdjacentHTML("beforeEnd",
"<object id=\"printWB\" width=0 height=0 \
classid=\"clsid:8856F961-340A-11D0-A96B-00C04FD705A2\"></object>");
printFireEvent(frame, eventScope, "onbeforeprint");
frame.focus();
window.printHelper = printHelper;
setTimeout("window.printHelper()", 0);
}
// helpers
function printIsNativeSupport() {
var agent = window.navigator.userAgent;
var i = agent.indexOf("MSIE ")+5;
return parseInt(agent.substr(i)) >= 5 && agent.indexOf("5.0b1") < 0;
}
function printFireEvent(frame, obj, name) {
var handler = obj[name];
switch ( typeof(handler) ) {
case "string": frame.execScript(handler); break;
case "function": handler();
}
}
function printGetEventScope(frame) {
var frameset = frame.document.all.tags("FRAMESET");
if ( frameset.length ) return frameset[0];
return frame.document.body;
}
function onprintHiddenFrame() {
function onfinish() {
printHiddenFrame.outerHTML = "";
if ( window.onprintcomplete ) window.onprintcomplete();
}
printFrame(printHiddenFrame.printMe, onfinish);
}
问题五:
程序中在Page_Load里面加上:btPrint.Attributes.Add("onclick","return PrintDataGrid(document.all('SheetList'))");
注:SheetList为需要打印的DataGrid ID,在查询后,btPrint为页面上打印按钮的ID
要打印Table控件,是不是只要只要把DataGrid控件的ID换为Table控件的ID就可以了呢??? --------------------编程问答-------------------- 大侠呢???帮忙看看啊。。。 --------------------编程问答-------------------- --------------------编程问答-------------------- 头晕中..... --------------------编程问答-------------------- parent.onprintHiddenFrame()
vGridContent = vDataGrid.outerHTML获取输出的内容。
打印
一、WebBrowser控件
<object ID='WebBrowser' WIDTH=0 HEIGHT=0 CLASSID='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'></object>
二、WebBrowder控件的方法
//打印
WebBrowser1.ExecWB(6,1);
//打印设置
WebBrowser1.ExecWB(8,1);
//打印预览
WebBrowser1.ExecWB(7,1);
三、实现打印的设置,打印数据的生成,打印的预览,和打印。
实现打印的设置,打印数据的生成,打印的预览,和打印我一般这样做,假如查询结果在a.asp中,那么在a.asp中放置打印设置、打印预览、打印三个按钮。
单击打印设置按钮则在js中执行WebBrowser1.ExecWB(8,1),以打开打印设置窗口。
单击打印预览按钮则打开一个b.asp,在b.asp中重新生成打印数据,然后在b.asp中自动执行WebBrowser1.ExecWB(7,1),以打开用户预览界面。
单击打印按钮则也打开b.asp,在b.asp中重新生成打印数据,然后在b.asp中自动执行WebBrowser1.ExecWB(6,1),以自动打印数据。
四、代码
a.asp调用数据的程序就不给出了。只给出几个按钮的代码:
<input type=“button“ name=“mPrint“ value=“打印“ onclick=“exePrint();“>
<input type=“button“ name=“mPreview“ value=“打印预览“ onclick=“exePreview();“>
<input type=“button“ name=“mSetting“ value=“打印设置“ onclick=“exeSetting();“>
