Chinese parameters passed to the action in JS are garbled

See: http://topic.csdn.net/u/20080602/11/0edf10dd-8b67-4d3e-ad9d-ff022d397e0b.html

Encode the Chinese characters in JS first...
Then decode the code in action...
Specific implementation...
JS Code
VaR comment = Document. All. Comment. value;
Comment = encodeuri (comment );
Comment = encodeuri (comment); // note twice

Action Decoding
String comment = request. getparameter ("comment ");
Try {
Comment = java.net. urldecoder. Decode (comment, "UTF-8 ");
} Catch (unsupportedencodingexception e ){
E. printstacktrace ();
}
Trace the variable value from the program and find the correct Chinese characters in the action, but the final query result is still a blank set. Execute sqlquery in the database to find that the query result is null, you have to set an encoding attribute of the original database, that is, change collation of sqlserver to chinese_prc_cs_ai.
