Hi,
I want to capture Tab and Shift-Tab in the onblur event of a dropdownlist in javascript. Is it possible?
Help Please
thanks,
Kishore

For what purpose? I'm not sure if there's a better way to do it but you could have a couple of global boolean variables for Tab and Shift. Add keydown and keyup methods to toggle the booleans accordingly. Then during the Blur you can just do a logical check on the two.

$(document).keydown(function() { //if shift key, set bool //if tab key, set bool});$(document).keyup(function() { //Check to see if either shift or tab, if so release them});$('#dropdown').blur(function() { //Check bools //If tab, do stuff //If shift+tab, do stuff});

You can add an additional boolean. If you switch to a control from another one you can first set the boolean to true. Inside of the new control, surround everything with a check on the boolean to see how you got into it. Don't forget to reset the value at the end of the block.

onblur is not enough... You need to capture KeyEvents and check and store if tab/shift-tab are pressed. Then you can check for those keys in the blur-handler.

when i use both the onblur and keyeventhandlers the onblur is getting fired and the keyevents are not getting fired...any idea???

Are there any events fired when you press a key? To trigger an onblur by shortcuts like tab or shift-tab, the onkeydown-event must be fired before.
