推荐答案

基于稍微不足的描述：



如果你'单击按钮时，在客户端重新工作。一旦你在客户端，最简单的控制是通过javaScript：给你的文本框一个ID并设置它的visibility ='hidden';当您的打印事件通过时（或在适当的时候），使用visibility ='visible'恢复;



如果打印在服务器上调用php，则可以在会话变量（例如）中捕获文本框的内容，然后通过AJAX使其消失。然后，您可以通过多种方式恢复文本框（甚至刷新页面）并从会话变量恢复文本。



这一切都取决于你在做什么打印。

Based upon the somewhat scanty description:

If you're working on the client side when you click the button. Once you are at the client, the easiest control is via javaScript: give your textbox an ID and set it's visibility='hidden'; when your print event is through (or whenever it is appropriate), restore with visibility='visible';

If the printing is calling php on the server, you can capture the contents of the textbox in a session variable (for example) and then make it go away via AJAX. Then, you restore the textbox in any number of ways (even refreshing the page) and restore the text from the session variable.

It all depends upon what you are doing to print.
