从其他网页访问“隐藏字段”值

Question

I have stored a string value in a hidden field of a page. How to access it from a different webpage?

Answer 1

You have two options.

a. Putting that string value in a Session.

  string value="value"; Session["myValue"] = value; 

b. Transmitting that value in the url.

 string value="value";
 Response.Redirect("./Mypage.aspx?value="+value);

Answer 2

On the page that contains the hidden value, you could post that form to the other page and get the value from this.Request.Form["hidden-field"].

Is that the sort of answer you are looking for? Maybe more details would help.

Good luck!

Answer 3

If you don't mind using jQuery, and as long as the pages are on the same domain, then you can do it with the .load() method. This method basically does a GET request to the page

Page with hidden field

<div id="hiddenValue">Value</div>

Page you're calling from

$('#newDiv').load('path/to/page.aspx #hiddenValue');

additional notes:

• Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy ; the request can not successfully retrieve data from a different domain, subdomain, or protocol.

If they are on different domains then your only other options are:

• Query Strings

• Sessions
