javascript - same logic across different button IDs -



javascript - same logic across different button IDs -

i have many select all buttons within html same thing. have different ids because buttons represent different divs have different content within them. new js , wondering how can perform same logic across many select all buttons when 1 of them clicked?

i thought putting each select all button in array containing ids , using

arr = [id1,id2,id3]; (var = 0; < arr.length; i++) { var k = document.getelementbyid(arr[i]); k.onclick = function() {//...logic...} }

i'm new js i'm not sure if method approach

your current code should work. create sure in array of ids, proper strings (put quotes around them). also, if plan on doing i within click callback, please read how javascript closures work?
