js 打印 jsp
我要实现的一个功能是在一个jsp页面中点击简易打印,然后window.open();一个新窗体,新窗体是我要打印的页面,新窗体会自动执行wb.ExecWB(7,1);实现打印预览,我想关闭预览之后新的窗体也关闭,请问怎么实现,下面是我写的,关闭预览窗体之后新窗口并没有关闭。wb.ExecWB(7,1); window.opener=null; window.open('','_self'); window.close();
回复讨论(解决方案)
wb.ExecWB(45,1);
wb.ExecWB(45,1);是直接打印吗,我用这个打开新窗口的时候页面一闪而过,不知道有没有打印,选择打印机的页面都没有出现啊。
