在页面到达window.print（）之前执行函数 [英] Executing function before page gets to window.print()
问题描述
我有一个调用window.print（）的页面;在页面的底部。我无法访问window.print（）;它由服务器生成，我无法触摸它。基本上是因为IE我需要在打印对话框出现之前执行一些javascript，但是在页面加载之后。我不能这样做因为它一旦到达window.print（）;出现打印对话框。我仍然需要打印，但首先我需要运行myFunction（）然后我可以运行window.print（）;
I have a page that calls window.print(); at the bottom of the page. I have no way of accessing the code around window.print(); Its generated by the server and I can't touch it. Basically because of IE I need to execute a bit of javascript before the print dialog comes up but after the page has loaded. I can't do this because as soon as it gets to window.print(); the print dialog comes up. I still need to print but first I need to run myFunction() then I can window.print();
<html><head></head><body></body><!--no access from here--><script>window.print();</script></html>
推荐答案
您应该可以像这样覆盖它。 。
You should be able to override it like so...
var _print = window.print;
window.print = function() {
alert("Hi!");
// do stuff
_print();
}
