I want to get checkbox value using jQuery when to uncheck the checked checkbox and show that unchecked

I've used JQuery to add a "image" button to a few rows in a table. I used the following

Say I have an unordered list, like so: <ul><li>One<li><li>Two<li><li

I have a structure of html like this:<div id="triger1">some elements inside<div>

I'm still new to JQuery,on the way to getting my ajax example to work i got stalled with setTime

I thought this would be rather simple but it seems the empty method is not working to clear out a tbody
