In the JSP, the value with the "percent%" is used to obtain the __JS with the Request.getparameter

So late, and did not eat dinner, I was so hungry I was writing code, and suddenly found me in the JSP if the parameter content contains%, such as the URL is:
url:= ' http://109.13.15.44:8080/sms_send2.do?corp_id= account name &corp_pwd= password &mobile=13344556677&msg_content = within 50% capacity ';
will report ' format error ', then I copied the URL in the program directly to the browser address bar, found that the same problem. Some can pass, some can't, really ghost, looked at the content, found that may be% of the problem, go online check, the answer is also very exotic,

The solution is to replace%, there is no language, well, there are two questions, one is not as long as there will be a% of this error, one is why% can, know it is still do not know why.
