我想用打印机

打印只有打印复选框的图像。我想通过打印机仅打印具有复选框的图像。如果有人选中img id = 9和8的复选框，然后单击打印类的按钮。通过打印机打印出img id = 9和8。你能帮助我吗？我想用打印机

<div class="container" id="main"><center><button class="btn btn-primary btn-lg print" id="print2">복사하기</button></center> 

    <div class="profile__body"> 
     <ul class="row first" data-bsp-ul-id="bsp-PkKH" data-bsp-ul-index="0"> 

      <li class="col-xs-4 post bspHasModal" data-bsp-li-index="0"><input type="checkbox"> 
       <div class="picture-square"><img id="9" src="/uploads/static_files/uploaded/2017/%EC%BA%A1%EC%B2%98.JPG" class="img-r img-responsive"></div> 
      </li> 

      <li class="col-xs-4 post bspHasModal" data-bsp-li-index="1"><input type="checkbox"> 
       <div class="picture-square"><img id="8" src="/uploads/static_files/uploaded/2017/%EC%BA%A1%EC%B2%98.jpg" class="img-r img-responsive"></div> 
      </li> 

      <li class="col-xs-4 post bspHasModal" data-bsp-li-index="2"><input type="checkbox"> 
       <div class="picture-square"><img id="7" src="/uploads/static_files/uploaded/2017/ddd.JPG" class="img-r img-responsive"></div> 
      </li><li class="clearfix visible-xs-block"></li> 

      <li class="col-xs-4 post bspHasModal" data-bsp-li-index="3"><input type="checkbox"> 
       <div class="picture-square"><img id="6" src="/uploads/static_files/uploaded/2017/%E1%84%89%E1%85%B3%E1%84%8F%E1%85%B3%E1%84%85%E1%85%B5%E1%86%AB%E1%84%89%E1%85%A3%E1%86%BA_2017-02-05_%E1%84%8B%E1%85%A9%E1%84%92%E1%85%AE_7.42.33.jpg" class="img-r img-responsive"></div> 
      </li> 

      <li class="col-xs-4 post bspHasModal" data-bsp-li-index="4"><input type="checkbox"> 
       <div class="picture-square"><img id="4" src="/uploads/static_files/uploaded/2017/2.JPG" class="img-r img-responsive"></div> 
      </li> 

     </ul> 
    </div> 

      </div>

这是我的js。

$(document).ready(function(){ 
     $("#print").on('click', function(ev){ 
      $('#main').prepend('<center><button class="btn btn-primary btn-lg print" id="print2">복사하기</button></center>') 
      $('.post').prepend('<input type="checkbox" />'); 
      ev.preventDefault(); 
     }); 
     $('input:checkbox').change(function(){ 
      if($(this).is(":checked")){ 
       $('img').addClass("img-print"); 
      } else { 
       $('img').removeClass("img-print"); 
      } 
     }) 
     $("#print2").on('click', function(){ 

     }) 
    });

添加类打印相关图像当您检查您的复选框。并在打印视图上将CSS分配给该类。 –

可以请你分享你的打印相关的JS代码？ – vijayP

@vijayP我加js。 –

选择什么检查的所有图像。

创建html（<img src='1.jpg'/> </br> <img src='5.jpg'/>）。

3.pass html value to mywindow.document.write（images）; http://www.w3schools.com/code/tryit.asp?filename=FCP6E6YV4S4T

<button> print </button>

$('button').on('click',PrintElem) 

function PrintElem() 
    { 
     var images = '' 
     $.each(selecedImages,(i,d)=>{ 
     images += '<img src = "+d+" /> ' 
     }); 


     mywindow.document.write(images); 


     mywindow.document.close(); // necessary for IE >= 10 
     mywindow.focus(); // necessary for IE >= 10*/ 

     mywindow.print(); 
     mywindow.close(); 

     return true; 

     } 
</script>
