窗口打印在单击一次后不起作用

Question

我有一个打印页面按钮，但点击一次后它不起作用。这是我的代码

  $('body').css('overflow', 'hidden');
  $('html').animate({ scrollTop: 0 }, 'fast', 'swing', function () {
    var printContents = document.getElementById("shipping-reservation-
    summary").innerHTML;     
    var originalContents = document.body.innerHTML;       
    document.body.innerHTML = printContents;      
    window.print();      
    document.body.innerHTML = originalContents;
    return false;
  })

只需隐藏您不想打印的div

    const printDiv = () => {
        for (const element of document.getElementsByClassName('invoice-actions')) {
          element.style.display = 'none';
        }
        window.print();
        for (const element of document.getElementsByClassName('invoice-actions')) {
          element.style.display = 'block';
        }
        
        return false;
 };
