Main content of this article:

If you use the print button that comes with your browser, you cannot perform other printing-related operations, such as the number of printing times. Therefore, you need to retain the browser printing function and assign it to the button you add. You can trigger the custom function when you click the button.
Copy codeThe Code is as follows:
<Input type = "button" class = "btnPrint" id = "btnPrint" value = "print"/>
<Iframe frameborder = 0 width = "100%" height = "400px" id = "printpd1_rame" src = "" <span style = "white-space: pre "> </span> </iframe>

Copy codeThe Code is as follows:
<Script type = "text/javascript">
$ ("# BtnPrint"). click (function (){
<Pre code_snippet_id = "248441" snippet_file_name = "blog_20140321_2_4849863" name = "code" class = "javascript"> <span style = "white-space: pre "> </span> printPDF (); </pre>}); function printPDF () {if (navigator. appName = 'Microsoft Internet Explorer ') {// Wait until PDF is ready to print if (typeof document. getElementById ("printpd1_rame "). print = 'undefined') {setTimeout (function () {printPDF ("printPDFIframe ");},
1000);} else {var x = document. getElementById ("printpd1_rame"); x. print () ;}} else {PDFIframeLoad (); // for chrome }}// for Chrome canceled/confirmed and cannot be directly sent to the printer function pd1_rameload () {debugger; var iframe = document. getElementById ("printpd1_rame"); if (iframe. src)
{Var frm = iframe. contentWindow; frm. focus (); // focus on contentWindow is needed on some ie versions frm. print (); return false ;}</script>
<Pre> </pre>
<Pre> </pre>
