1) @mauno-v told use liste_des_points instead of listedespoints loop.

2) in loop use secnd , third entry liste_des_points[i][1], liste_des_points[i][2] while create 2 entries.

3) in click event use locations[i][0] locations not defined.

so create list 3 entries ['location name','latitude','longitude'] or change indices , variable names.

see below:

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
