使用window.open方法(如果已打开)关闭该窗口并每次通过关闭前一个窗口来打开新窗口。
<script type="text/javascript">
function PrintGPass(content) {
var leftPosition, topPosition, width, height;
width = 800;
height = 600;
//Allow for borders.
leftPosition = (window.screen.width / 2) - ((width / 2) + 10);
//Allow for title and status bars.
topPosition = (window.screen.height / 2) - ((height / 2) + 50);
//Open the window.
// var h = "<html><head></head><body ><h4a>Visitor Pass</h4a><p><h9>This is a variable I want to print to the printer with the browser!</h9></p></body></html>"
// $('.printable').html(h);
var printWindow = window.open('', "Attachment", 'height=' + height + ',width=' + width + 'left=' + leftPosition + ',top=' + topPosition + ',screenX=' + leftPosition + ',screenY=' + topPosition);
// window.open('', "Print-Window", "status=no,height=" + height + ",width=" + width + ",resizable=yes,left=" + leftPosition + ",top=" + topPosition + ",screenX=" + leftPosition + ",screenY=" + topPosition + ",toolbar=no,menubar=no,scrollbars=no,location=no,directories=no");
//printWindow.document.write(content);
printWindow.document.write(content);
//document.getElementById("Image1");
// printWindow.document.close();
// printWindow.print();
// printWindow.close();
}
