js调用HttpPrinter(web打印插件)

对比了 康虎云报表 lodop 后 选择了 HttpPrinter (原因: 功能免费 只有源码收费)

demo地址:
https://www.lanzous.com/b743805

js代码如下,base64的部分已经精简:

<!DOCTYPE html>
<html>
<head>

<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>

<script>

$(document).ready(function(){

//获取打印机列表 begin
$("#btn_getprintlist").click(function(){
var ip = $("#ip").val();
var port = $("#port").val();

if(ip==""||port==""){alert("ip,port不能为空"); return false;}

//$.post("http://127.0.0.1:12345/getprinterlist",
$.post("http://"+ip+":"+port+"/getprinterlist",
{
  //method:"Donald Duck",
  //city:"Duckburg"
},
function(data){
    data = decodeURIComponent(data);
    //alert(data);

    if(data==""){
        alert("连接HttpPrinter失败");
    }else{
        //alert(data);
        var obj = JSON.parse(data);
        //alert(obj.status);

        $("#PrinterS").empty();

        if(obj.status=="ok"){
            alert("获取成功");

            //

            //$("#PrinterS").append("<option value='"+obj.sites[1].name +"'>"+obj.sites[1].name +"</option>"); 
            for(var o in obj.data){  
                //alert(o);  
                //alert(obj.data[o]);  
                var printname = obj.data[o].name;
                //alert(printname);
                $("#PrinterS").append("<option value='"+printname +"'>"+printname +"</option>"); 
             }  

        }else{
            alert("获取失败:"+obj.data);
        }
        //console.log(data);

    }
