html页面直接导出word pdf
直接上代码
html
<div id="div_workInfo">
///这里放想要导出的html 元素
</div>
<form action="@Url.Action("ExportWord")" method="post" id="formWord"> <input type="hidden" id="hidWord" name="hidWord" /></form>
function ExportWord() {
var html = $("#div_workInfo").html();
$("#hidWord").val(encodeURIComponent(html));
$("#formWord").submit();
} ///from 表单方式提交这段html
接下来就是后台接收了
[HttpPost]
public ActionResult ExportWord(FormCollection form)
{
string html = Server.UrlDecode(form["hidWord"]);///接收前台的html的
byte[] pdfFile = this.ConvertHtmlTextToPDF(html);///pdf 执行这个就可以了
///这里执行word 操作
sb.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:w=\"urn:schemas-microsoft-com:office:word\" xmlns:m=\"http://schemas.microsoft.com/office/2004/12/omml\"xmlns=\"http://www.w3.org/TR/REC-html40\">");

sb.Append("<div class='Section1' style='font-family:宋体;'>");
sb.Append(html);
sb.Append("</div> </body>");
sb.Append("</html>"); 说明一下 加了style 可以设置页面方式为横向 加html 那边 可以设置web视图为 页面视图
return File(pdfFile, "application/pdf", "" + "报销表_" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".pdf");
}
这里用到了 iTextSharp 直接可以直接在项目nuget 里面下载安装
/// <summary>
/// 将Html文字 输出到PDF档里
/// </summary>
/// <param name="htmlText"></param>
/// <returns></returns>
public byte[] ConvertHtmlTextToPDF(string htmlText)
{
if (string.IsNullOrEmpty(htmlText))
{
return null;
}
//避免当htmlText无任何html tag标签的纯文字时，转PDF时会挂掉，所以一律加上<p>标签
htmlText = "<p>" + htmlText + "</p>";
MemoryStream outputStream = new MemoryStream();//要把PDF写到哪个串流
byte[] data = Encoding.UTF8.GetBytes(htmlText);//字串转成byte[]
MemoryStream msInput = new MemoryStream(data);
Document doc =new Document();//要写PDF的文件，建构子没填的话预设直式A4
PdfWriter writer = PdfWriter.GetInstance(doc, outputStream);
//指定文件预设开档时的缩放为100%
PdfDestination pdfDest = new PdfDestination(PdfDestination.XYZ, 0, doc.PageSize.Height, 1f);
//开启Document文件
doc.Open();
//使用XMLWorkerHelper把Html parse到PDF档里
XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, msInput, null, Encoding.UTF8, new Models.UnicodeFontFactory());//UnicodeFontFactory 这个类是防止中午问题的 我在下面贴一下 直接复制过去就OK了
//将pdfDest设定的资料写到PDF档
PdfAction action = PdfAction.GotoLocalPage(1, pdfDest, writer);
writer.SetOpenAction(action);
doc.Close();
msInput.Close();
outputStream.Close();
//回传PDF档案
return outputStream.ToArray();
}
UnicodeFontFactory 类 的内容 继承FontFactoryImp 类
public class UnicodeFontFactory : FontFactoryImp
{
private static readonly string arialFontPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts),
"arialuni.ttf");//arial unicode MS是完整的unicode字型。
private static readonly string 标楷体Path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts),
"KAIU.TTF");//标楷体
public override Font GetFont(string fontname, string encoding, bool embedded, float size, int style, BaseColor color,
bool cached)
{
//可用Arial或标楷体，自己选一个
BaseFont baseFont = BaseFont.CreateFont(标楷体Path, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
return new Font(baseFont, size, style, color);
}
}
///导出的pdf 这个是百度上看到的自己抄了一下 发表主要是为了自己收集下来 发表的内容这里都有用过是有效果的
