An issue about Ajax Data Transmission

Source: Internet
Author: User

Problem: Use ajax to pass string variables from the front-end page to the server. The content to be transmitted is ABC +, but after receiving the data, use system. Out. println () to output ABC spaces.

Cause: Some Characters in the URL are escaped. For example, if a space is encoded as a plus sign, the passed parameter is obviously a plus sign, but the obtained value is a space. How can this problem be solved? If a parameter is transmitted through a URL, it must be encoded as necessary.

Solution:

Add the following code to the client before encoding:

Function urlencode (SSTR)
{
Return escape (SSTR ). replace (// +/g, '% 2B '). replace (// "/g, '% 22 '). replace (// '/g,' % 27 '). replace (// G, '% 2f ');
}
VaR STR = urlencode ("ABC + ")
