Lodop云打印控件使用

1，虚拟打印机  迅捷PDF虚拟打印机

学习云打印时可以使用虚拟打印机，省去一些麻烦

2，后台网页文件部署相关js类文件

"javascript" src="LodopFuncs.js">

 

3，前端安装lodop程序（注：前端安装的程序要与浏览器的位数一致，而不是与操作系统的位数一致）

4.1，前端代码，前端直接使用

"button" value="打印预览" onclick="prn1_preview()">//点击事件，交互开始   var LODOP; function prn1_preview() {   //被绑定的js函数，调用lodop代码参数         CreateOneFormPage();             if (LODOP.CVERSION) CLODOP.On_Return=function(TaskID,Value){document.getElementById('S1').value=Value;};         document.getElementById('S1').value="打印预览返回结果："+LODOP.PREVIEW();         document.getElementById('id01').disabled = true;     };     function CreateOneFormPage(){   //lodop代码         MyData=document.getElementById('data01').value; //打印前变量重读一下最新值         LODOP=getLodop();                          LODOP.PRINT_INIT("");         LODOP.SET_PRINT_MODE("PROGRAM_CONTENT_BYVAR",true);         LODOP.ADD_PRINT_SETUP_BKIMG("C:\\Users\\Administrator\\Desktop\\新建文件夹\\顺丰5.png");         LODOP.SET_SHOW_MODE("BKIMG_IN_PREVIEW",true);         LODOP.ADD_PRINT_TEXT(87,5,274,47,"11111");            LODOP.ADD_PRINT_TEXT(159,9,270,47,"132132131演示变量");         LODOP.SET_PRINT_STYLEA(0,"ContentVName","MyData");     };

 

4.2，前端+后台

//前端 var LODOP; function prn1_preview() {            LODOP=getLodop();         try{             LODOP.PRINT_INIT("");           }catch(e){             alert("请先安装打印控件");return;         }         var a = [];         $('.checkLst:checked').each(function(i){             a.push({name:'id_'+i,value:$(this).val()});         });         if(a.length<1){             alert('请勾选记录');return;         }           a.push({name:'_order',value:$('#pagerForm input[name="_order"]').val()});         a.push({name:'_sort',value:$('#pagerForm input[name="_sort"]').val()});         $.post('__URL__/printLocation',a,function(data){               try{                 eval(data);//将后台返回的json数据作为js代码执行             /*for(var i in data){                   eval(data[i]);                 LODOP.NewPageA();             }*/ /*        LODOP.SET_PRINT_PAGESIZE(1,600,400,"");         LODOP.ADD_PRINT_TEXT(3,3,225,25,"库位信息");         LODOP.SET_PRINT_STYLEA(0,"FontSize",13);         LODOP.SET_PRINT_STYLEA(0,"Alignment",2);         LODOP.SET_PRINT_STYLEA(0,"Bold",1);         LODOP.ADD_PRINT_TEXT(25,3,235,25,"dsaddsad211112111131231231233211");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);         LODOP.ADD_PRINT_TEXT(41,3,235,25,"新加文本3");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);         LODOP.ADD_PRINT_TEXT(58,3,235,25,"新加文本4");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);         LODOP.ADD_PRINT_TEXT(75,3,235,25,"新加文本5");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);         LODOP.ADD_PRINT_TEXT(92,3,235,25,"新加文本6");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);         LODOP.ADD_PRINT_TEXT(109,3,235,25,"新加文本7");         LODOP.SET_PRINT_STYLEA(0,"FontSize",10);*/             //console.log(data);             LODOP.PREVIEW();             }catch(e){             alert('未安装打印控件');return;         }         });         //document.getElementById('id01').disabled = true;     };   //后台    function printLocation()     {         $id=I('post.');         $str=implode(',',$id);         $model=M("GoodsPosition");         $data=$model->field('path_part,path_shelves,path_layer,path_grid,goods_no')->where(array('id'=>array("in",$str)))->select();           $lodop='LODOP.SET_PRINT_PAGESIZE(1,600,400,"");LODOP.ADD_PRINT_TEXT(3,3,225,25," 库位信 息");LODOP.SET_PRINT_STYLEA(0,"FontSize",13);LODOP.SET_PRINT_STYLEA(0,"Alignment",2);LODOP.SET_PRINT_STYLEA(0,"Bold",1);';         $height=3;         foreach ($data as $key => $v) {             $height+=17;             $loc=$v['path_part'].$v['path_shelves'].$v['path_layer'].$v['path_grid'].'#'.$v['goods_no'];             $lodop.='LODOP.SET_PRINT_STYLEA(0,"FontSize",10);LODOP.ADD_PRINT_TEXT('.$height.',3,235,25,"'.$loc.'");';         }

 

--------------------------更新---------------------------

因lodop的不兼容性，以及eval()函数可能会被浏览器屏蔽，建议直接在前端使用lodop控件，而且效率更高

HTML代码：

                

            

        

"vo" name="list">             "id" rel="{$vo['id']}">

"{$vo.path_part}{$vo.path_column}{$vo.path_shelves}{$vo.path_layer}" goods_no="{$vo['goods_no']}" class="checkLst" name="ids" value="{$vo['id']}" type="checkbox">{$vo.path_part}{$vo.path_column}{$vo.path_shelves}{$vo.path_layer}

{$vo['goods_no']}

 

jq代码：

//打印库位信息    ---By hc

var LODOP;

function prn1_preview() {   

        LODOP=getLodop();

        LODOP.PRINT_INIT("");

        LODOP.SET_SHOW_MODE("NP_NO_RESULT",true);

        LODOP.SET_PRINT_PAGESIZE(1,600,400,"");

        LODOP.ADD_PRINT_TEXT(3,3,189,25,"库位信息");

        LODOP.SET_PRINT_STYLEA(0,"FontSize",13);

        LODOP.SET_PRINT_STYLEA(0,"Alignment",2);

        LODOP.SET_PRINT_STYLEA(0,"Bold",1);

        LODOP.SET_PRINT_STYLEA(0,"ItemType",1);

        LODOP.SET_PRINT_STYLEA(0,"Horient",2);

                           

        var str='';

         var checks = document.getElementsByName("ids");

        if($('.checkLst:checked').attr('bnno')!='' && $('.checkLst:checked').attr('type')=='checkbox'){

            $('.checkLst:checked').each(function(i){

                var v =    $(this).attr('path')+'#'+ $(this).attr('goods_no');

                if(i"\r\n";}

 

                str += v;

            });

            LODOP.ADD_PRINT_TEXT(27,3,189,100,str);

            LODOP.SET_PRINT_STYLEA(0,"FontSize",11);

            LODOP.SET_PRINT_STYLEA(0,"ItemType",4);

            LODOP.PREVIEW();

        }else{

            alert("请勾选所需打印的鞋码");

        }

};
