Solving the problem of Chinese garbled characters in XMLHttpRequest

The default character encoding for data obtained through XMLHttpRequest is UTF-8. If the front-end page is GB2312 or other encoding, the data obtained is displayed as garbled characters. . Through XMLHTTPRequest, the POST data is also UTF-8 encoded. If the background is GB2312 or other encoding, garbled characters will appear.

Solution:

• Unify to UTF-8. This is also an inevitable trend of internationalization.

• When outputting text obtained through XMLHttpRequest, add text declarations in headers (direct HTML declarations have no effect).

For example:

PHP:header('Content-Type:text/html;charset=GB2312'); ASP:Response.Charset = "GB2312" JSP:response.setHeader("Charset","GB2312");
