I created an instant search similar to google search using JQuery.
Q1. The post to search.php using search function searchq() then print out the returned result works fine, but the createq() function doesn't work at all, it didn't triggered when I using alert() to test, any ideas on how to fix it so the variable txt could be post to create_object.php (which has been post successfully to search.php).
Q2 I want to create a function that allow the user to direct to the first search result(which is anchored with an url) when the enter is pressed, any idea how to achieve this? I tried something but it messed up.
Note that I didn't include the connect to database function here. Coz I think the database username and password setting would be different to yours.So please create your own if you want to test it. The mysql is set with a table is called "objects", and it has one column named "name".
Thanks in advance!
