This weather code is placed in the webpage, and the city cannot customize it. Please ask someone for advice. Urgent!

This is because cross-domain reading of Cookie ie by iframe is automatically blocked. If you don't believe me, look at the status below. There is a red sign. Just click and have a look yourself. You can minimize it, so you can read it. But it is impossible for everyone to lower IE.

Iframe cross-domain access cookie solution to google solution, and finally find a way for iframe internal page operation:

1. Response. AddHeader("P3P ","CP = Cao psaour "); Add to header

2. Open IIS

Administrative tools-> select website-> properties -> http header, and add http header.

Then enter the name: P3P.

Enter header content: CP=CAO PSA OUR.

Problem solved.

Why not your own list? You'd better look for cross-domain Cookie about Iframe.
