}, 100)因为要求不能把打印的数据显示在页面上,所以通过iframe的方式去实现。单纯的截取字符串重新赋值body内容能进行打印却把打印的内容展现在页面中了,所以不行。打印针对IE的浏览器进行了一定程度的调整,IE打印要做特定的处理,详见上面判断代码。打印内容通过模板字符串加内联样式去实现。满足了基本需求。是否应该也通过截取页面字符串的方式去做可能比较浪费性能些,为什么这么说?因为样式在打印的小票上有一定程度的偏差,修了东墙破了西墙,只能采取相对的方式取舍。如果这种写法不满足,可以采取截取字符串写class尝试。以上就是js实现浏览器打印功能的示例代码的详细内容,关于js 浏览器打印的资料请关注其它相关文章!
