Javascript-js How to implement the functions of multiple search boxes

I would like to do a search box similar to the following, when the user enters a value, click on the options above will jump to different links,

For example, I enter QQ,
Click on the "News" above, will jump to NEWS.PHP/?KW=QQ
Or click on the "" above and jump to HWEIXIN.PHP/?KW=QQ
Or click on "Ask" above. Will jump to WENWEN.PHP/?KW=QQ
.........
