Deselecting other checkboxes if one is selected

Suppose I have a checkbox style question - "What fruits do you like?" and the options are: * Apples * Bananas * Oranges * Unsure I want to try and implement two functionalities: 1. In case the user selects "Unsure", then I'd want the other checkboxes to be deselected 2. If afterwards the user deselects "Unsure", then the selections made previously should reappear I need to necessarily figure out a way to implement (1). (2) would be a nice-to-have, but not wholly needed. Follows is the code, wherein I tried to implement this: jQuery("#QID10-4-label").click(function(){ if(jQuery("#QID10-4-label").hasClass("q-checked")){ //This will be implemented if the user has selected option 4 jQuery("#QID10-1-label").prop("q-checked", false); jQuery("#QID10-2-label").prop("q-checked", false); jQuery("#QID10-3-label").prop("q-checked", false); } else { //This will be implemented if the user has deselected option 4 //Ideally I'd want to be able to reselect those options which had been previously selected if any } }); Any help on this would be much appreciated. Thanks!
