javascript - Simple math addition in JS giving wrong result -
i have strange problem can't head around. try find highest number in list of elements have data-index attribute respective number. when iterating on them, js insists 9 < 10 false.
see fiddle: http://jsfiddle.net/1ztbxbjx/
what i'm doing wrong?
i can't use
for (i = 0; < $('div[data-index]'; i++))
sometimes there numbers out of order in list (eg. 1,2,3,4,5,25,31).
you need parse id, otherwise you're comparing strings. here example using parseint()
