My javascript is under document.ready function 我的JavaScript在document.ready函数下

If you defined the printDiv function inside another function, it's not visible to your onclick HTML parameter. 如果在另一个函数中定义了printDiv函数，则onclick HTML参数不可见。

You can either define it as a global function, or add an eventListener to your element inside your document.ready function : 您可以将其定义为全局函数，或者将eventListener添加到document.ready函数内的元素中：

 function printDiv(divName) { var printContents = document.getElementById(divName).innerHTML; var originalContents = document.body.innerHTML; document.body.innerHTML = printContents; window.print(); document.body.innerHTML = originalContents; } $( document ).ready(function() { document.getElementById("printButton").addEventListener("click", function() { printDiv('print'); }); });

 <!DOCTYPE html> <html lang="en"> <head> <script src="https://code.jquery.com/jquery-2.2.4.js"></script> </head> <body> <input type="button" id="printButton" value="Print PDF"></input> <div id="print"></div> </body> </html>
