A jQuery plugin to selectively disable the iOS double-tap-to-zoom action on specific page elements (and have that generate two click events instead).

        if (!dt || dt > 500 || fingers > 1) return; // not double-tap

        e.preventDefault(); // double tap - prevent the zoom
        // also synthesize click events we just swallowed up

Hey johan,

thanks for the snippet!
I'd just recommend adding a "return this;" to make it chainable.

Thanks for this!

Thank you for this. I am using the presses of the button to call a function to increment a counter. I need the double taps to call my function twice. Might it be OK for me to call $(this).trigger('click').trigger('click'); twice in the section // also synthesize click events we just swallowed up.

Thank you again.

Thanks for your idea, I need to port this snippet to javascript.

It dosnt seem to work?

Works great, thanks a lot!
I suggest lowering the time between the two taps because it prevents fast scrolling of the page.
200ms should be enough.

Definitely save my day. thank you so much

it is not working, i just check my iphone 7plus moblie.double tap to zoom still working on my mobile
