Transform your information into properly encoded data for the request by utilizing the encodeURIComponent() function:
xhr.open("POST", url, true);
xhr.send(encodeURIComponent(postdata));
Understanding the mechanics of URL encoding is essential. Rather than using a plus sign, it's recommended to properly escape or encode the data being sent to the server. Test by typing "a+b c" in this link.
The symbol "+" in URL encoding represents a space. Therefore, when the posted data is decoded, any instances of "+" will be replaced with spaces.
The reason behind this is that URL Encoding transforms spaces into +, as spaces are not allowed in URLs.
Typically, characters are changed to % followed by two hexadecimal digits, but using + instead of %20 makes URLs more legible.
If you encode your + as %2B, it should function correctly.
It is likely that you have come across the + sign in a URL, which is actually transformed into a space because it represents a space character in URLEncoded form.
To encode any value for a URL, consider using escape() to convert it into URL-encoded format.
It is common practice to encode URLs to ensure proper handling by servers. When converting a plus sign, it will be translated into a space on the server side. To include a plus sign in your URL, you must escape it using %2b.
