试用此代码

＆＃13;

$(function () {
  $("#btnPrint").click(function () {
    var contents = $("#dvContents").html();
    var frame1 = $('<iframe />');
    frame1[0].name = "frame1";
    frame1.css({ "position": "absolute", "top": "-1000000px" });
    $("body").append(frame1);
    var frameDoc = frame1[0].contentWindow ? frame1[0].contentWindow : frame1[0].contentDocument.document ? frame1[0].contentDocument.document : frame1[0].contentDocument;
    frameDoc.document.open();
    //Create a new HTML document.
    frameDoc.document.write('<html><head><title>DIV Contents</title>');
    frameDoc.document.write('</head><body>');
    //Append the external CSS file.
    frameDoc.document.write('<link href="style.css" rel="stylesheet" type="text/css" />');
    //Append the DIV contents.
    frameDoc.document.write(contents);
    frameDoc.document.write('</body></html>');
    frameDoc.document.close();
    setTimeout(function () {
      window.frames["frame1"].focus();
      window.frames["frame1"].print();
      frame1.remove();
    }, 500);
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="dvContents">
