How To Use Javascript To Keep A Running Score On Multiple Choice October 06, 2022 Post a Comment I've been trying to work this one out for ages, but just can't seem to wrap my brain around it. Here's my HTML: Select Solution 1: Because you've declared total outside the scope of your change handler, it will retain its last assigned value and therefore any further changes will be applied to the updated total rather than the original one of 0. If you need to update on each select, you should declare the variable locally and recalculate using all the current values of your select elements: $('select').change(function() { var total = 0; $('select').each(function() { total += Number($(this).val()); }); $('.total').text(total); }) Copy Fiddle: https://jsfiddle.net/zgj6sq05/ Solution 2: Here's your problem var score = 0; var scoreNew = 0; $('select').change(function() { scoreNew = parseInt($(this).val()) + parseInt(score); //score is always 0 $('.total').text(scoreNew); }) Copy You add the new score to 0. Change that line to scoreNew += parseInt($(this).val()); Copy and get rid of the score var. Not sure why it's there? Edit: Updated method $('select').change(function() { var score = 0 // run through each value and rebuild score $('select').each(function(){ score += parseInt($(this).val()) }) $('.total').text(score); }) Copy It rebuilds the score on every change. Seems lame but it's quite fast. I'm hoping this is a "test" project since nothing here is production level. Here's a fiddle if you can't get it to work.
