I couldn't figure out to do it unless I added some form of ID to each input field. I'm not sure how one can get the place of an element within a jQuery object, so this is how I approached your problem.
Tested in Win/FF2 <form> <input type="checkbox" id="1"><label>box 1</label><br /> <input type="checkbox" id="2"><label>box 1 and 2</label><br /> <input type="checkbox" id="3"><label>box 1 and 2 and 3</label><br /> <input type="checkbox" id="4"><label>box 1 and 2 and 3 and 4</label><br /> </form> <script> $(document).ready( function () { $("[EMAIL PROTECTED]").each( function () { $(this).bind( "click", function () { $(this).siblings("[EMAIL PROTECTED]").lt($(this).id()-1).each( function () { $(this).attr( { checked: 'true' } ); } ) } ) } ) } ); </script> The code can be cleaned up a bit, but I like making it verbose while trying to figure things out so that's what you get. If someone knows how to snag the place of an element within a jQuery collection so that number can be passed to the lt() function I'd love to hear it. -ALEX ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Glen Lipka Sent: Monday, November 27, 2006 4:27 PM To: jQuery Discussion. Subject: [jQuery] Checkbox: Selecting all Previous This might be a newbie question, but I am having trouble with it. I have 4 checkboxes vertical <input type="checkbox"><label>box 1</label><br /> <input type="checkbox"><label>box 1 and 2</label><br /> <input type="checkbox"><label>box 1 and 2 and 3</label><br /> <input type="checkbox"><label>box 1 and 2 and 3 and 4</label><br /> When I click one, I want to check the boxes of all the ones previous to it (including it). And uncheck all the boxes after it. How would I structure the statement in jQuery to select? I am trying to avoid the FOR loop. This gives me the last one. var lastOne = $("#myForm [EMAIL PROTECTED]:checked:last"); Not sure how to use this. I tried prev() but that didnt seem to work. Thanks for the help, Glen
