确认对话框后显示打印窗口

标签： jquery ruby-on-rails

在某些情况下，我必须首先显示一个确认对话框，如果用户单击“确定”，它将显示打印窗口，如果用户单击“取消”，则将不显示打印窗口。

a href =“＃” class =“ btn btn-sm主浮动右边隐藏打印<％= params [：print_on_load]？” Mandatory_print_invoice“：”“％>” onClick =“ window.print（）; “>打印一个

点击打印后，将显示打印窗口。但是我必须先在单击“打印”后显示一个确认对话框，然后它将显示“打印”窗口

您应该这样做

document.querySelector('button').onclick = () => {
  if (confirm("Do you want to print?")) {
    window.print();
  }
}
<button>Print</button>
