javascript - JS touchmove events that stop triggering. -


i have webapp project working graphical chart want respond touchstart , touchmove events. have events bound element overlaying chart canvas element , part working expected.

i however, experiencing behavior events stop triggering. seeing happen in @ least 2 ways:

first case: appears sporadic stopping (i can't narrow down is going on right before stop). work fine while touch events stop triggering.

second case: when update app (which removes bound element, reappends new element dom, , re-binds new element same events). after update 1 single touchstar/touchmove trigger. after single firing no further touch events trigger.

here website working on: mortgagevista.com

i can't life of me figure out going on. have spent hours reading on forums , , still can't seem figure out issue is. unfortunately out of ideas on how troubleshoot problem. have been using emulator in chrome dev tools reproduce problem.

does issue sound familiar anybody? common issues or pitfalls touch events might missing? ideas on how best go troubleshooting this? (sorry, know vague question out of ideas on how narrow down happening).

your events not going right place. there 2 possible reasons this.

  1. an incorrect element has focus.
  2. an invisible overlay or similar not getting clicked expect.

drill these issues , see if can find root cause.

good luck.
