ASP. NET cannot obtain the method for setting cookies in JS.

Add "path = expiration time" to the js method to solve this problem.

Example: // write cookiesCopy codeThe Code is as follows: function setCookie (name, value)
{
Document. cookie = name "=" escape (value) "; path =/"; // The cookie is disabled.
}

Add a path =. That's simple.

Here, the Path attribute of Cookie is set. You must set the Path = "/" attribute on both the client and server to allow js and ASP. NET to perform Cookie operations on each other! Another issue is encoding. Here, the encoding in JS is encodeURI, which corresponds to Server. URLEncode of ASP. NET.
