I've build a suit on http://jsfiddle.net/57dZQ/

it seems that the callback of 'touchend' in zepto.js:1340 execute twice


  • to reproduce this issue, you need to open the 'Emulate touch events' of chrome developer tool
  • then open http://jsfiddle.net/57dZQ/
  • and wait for a while, click the iframe whose src is 'zeptojs.com', you will see some error log 'Uncaught TypeError: Cannot call method 'trigger' of undefined '

is anyone who was faced with the same problem?

Can't reproduce (Chrome 21.0.1180.89)

Only happens in an iframe? Smells like browser bug with emulating touch events, not Zepto bug.

em, i tried to reproduce on another computer with different version of chrome, and they are all result in error called 'Uncaught TypeError: Cannot call method 'trigger' of undefined '.

have you open the option of 'Emulate touch events' ?

just open this option and click the iframe in http://jsfiddle.net/57dZQ/

it seems that this issure only happens in iframe.

Can't reproduce & closing. Feel free to re-open with a test case that fails for current master when including touch.js.
