Garbled, garbled, head big, annoying, say set Tomcat can be resolved, but sometimes regardless of the use, at this time, we can consider the way of transcoding not directly to the Chinese, in JS with escape transcoding, remember the need to use two times, such as:
var Str=escape ("This is Chinese parameter");
Str=escape (str);
XXX.DO?NAME=STR;
In the background through a class of methods to turn back again:
Escape.unescape (Request.getparameter ("name"));
Escape classes are as follows:
Copy Code code as follows:
Package com.laneasy.hy.util;
