I believe he wants a page opened in one tab to be able to affect a control in a page opened in another tab.

推荐答案

In general, this doesn't make sense.

When your second page is executing, the first page is gone. It simply no longer exists. There is no label for you to assign to.

Even if you could assign to the label, the previous request is over. The HTML (without the change) has already been sent to the user's browser.

一种可能是，您可以使用类似问题的查询字符串(或其他用于将数据从page1发送到page2的状态管理概念)重定向页面并将其分配给标签.

one posssibility is you can use querystring like thing (or other state management concepts for sending data from page1 to page2)redirect the page and assign it to label.

Well if this what u mean the two pages will be open u can make session and u can make timer to check about the value of session if it have value you can change the text of label .
