在html页面上点击打印按钮，执行js方法

function Print() {

var dgRows = $('#dg').datagrid('getSelections');

if (dgRows.length <= 0) {

alert('请勾选需要打印的行！');

return;

}

var outArray = new Array();

for (var i = 0; i < dgRows.length; i++) {

outArray.push({ "cHBCode": dgRows[i].cHBCode, "cHBName": dgRows[i].cHBName });

}

var a = JSON.stringify(outArray);

//alert(a);

$.post("../../../GenerateQRCodeTag/TestBartenderPrint.ashx?cType=StorageBag", a, function (data) {

if(data=="error")

{

$.messager.alert("打印失败！");

}

});

}

一般处理程序TestBartenderPrint.ashx中的实现方法步骤为

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.Web;

using System.Web.Script.Serialization;

using bartenderClassLibrary;

namespace AdminLTE.GenerateQRCodeTag

{

///

/// TestBartenderPrint 的摘要说明

///

public class TestBartenderPrint : IHttpHandler

{

public void ProcessRequest(HttpContext context)

{

context.Response.ContentType = "text/plain";

Class1 classTest = new Class1();//bartenderClassLibrary.dll中的类名

StringBuilder sb = new StringBuilder();

string test = context.Request.QueryString["cType"];

if (test == "HealthyBag")

{

List dicParameter = GetHealthyBagParameter(context);

for (int i = 0; i < dicParameter.Count; i++)

{

string str = dicParameter[i].cHBCode + ";" + dicParameter[i].cHBName;

string path = "F:\test.btw";

try

{

classTest.barTenderM(path, str);

}

catch(Exception ex)

{

context.Response.Write("error");

throw;

}

}

}

}

private List GetHealthyBagParameter(HttpContext context)

{

StreamReader reader = new StreamReader(context.Request.InputStream);

String strJson = HttpUtility.UrlDecode(reader.ReadToEnd());

JavaScriptSerializer jss = new JavaScriptSerializer();

List dicParameter = jss.Deserialize>(strJson);

return dicParameter;

}

public bool IsReusable

{

get

{

return false;

}

}

}

public partial class SelectListHealthyBagTest

{

public string cHBCode { get; set; }

public string cHBName { get; set; }

}

}

barTenderM方法存在于类库

bartenderClassLibrary.dll中，实现的是通过C#对bartender的打印操作

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace bartenderClassLibrary

{

public class Class1

{

private static BarTender.Application btApp;

private static BarTender.Format btFormat;

public void barTenderM(string path,string str)

{

string code, codeName;

btApp = new BarTender.Application();

string[] sArray = str.Split(';');

code = sArray[0];

codeName = sArray[1];

btFormat = btApp.Formats.Open(path, false, "");

btFormat.PrintSetup.NumberSerializedLabels = 1;

btFormat.SetNamedSubStringValue("QRCodeTest1",code);

btFormat.SetNamedSubStringValue("txtFont1",codeName);

btFormat.PrintOut(true, false);

btFormat.Close(BarTender.BtSaveOptions.btDoNotSaveChanges);

btApp.Quit(BarTender.BtSaveOptions.btSaveChanges);

}

}

}
