Hi, I am writing a jquery phonegap quiz app and have a number of categories from which a user can select via checkbox. Relevant questions belonging to those categories are then returned. However, I have two huge switch statements to change the relevant variables from 0 to 1 if the checkbox for that category is selected and vice versa (this info is used to build a compound db query). The value of the variable behind the checkbox is only ever 0 or 1, so is there a better way to do this? My HTML is: <h2>Categories</h2> <ul class="rounded"> <li>Cardiology<span class="toggle"><input type="checkbox" id="cardiology" /></span></li> <li>Respiratory<span class="toggle"><input type="checkbox" id="respiratory" /></span></li> <li>Gastrointestinal<span class="toggle"><input type="checkbox" id="gastrointestinal" /></span></li> <li>Neurology<span class="toggle"><input type="checkbox" id="neurology" /></span></li> </ul> My Javascript is along the lines of: var toggle_cardiology = 0; var toggle_respiratory = 0; var toggle_gastrointestinal = 0; var toggle_neurology = 0; $(function() { $('input[type="checkbox"]').bind('click',function() { if($(this).is(':checked')) { switch (this.id) { case "cardiology": toggle_cardiology = 1; break; case "respiratory": toggle_respiratory = 1; break; case "gastrointestinal": toggle_gastrointestinal = 1; break; case "neurology": toggle_neurology = 1; break; etc. (which is cumbersome with 10+ categories plus an else statement with a switch to change them back) I'm thinking of something along the lines of concatenating the HTML id tag onto the "toggle_" prefix - in pseudocode: if (toggle_ + this.id == 1){ toggle_ + this.id == 0} if (toggle_ + this.id == 0){ toggle_ + this.id == 1} Thanks, Nick.
