1.1 RC1 iOS Input Field Zoom #3690

On iOS when you tap into an input field the browser zooms in and then back out.

Tap to focus on the field and it will zoom on 1.1:

Same thing on 1.0.1 works fine:

Tested on iOS 4.x and 5.x


It looks like this happens on the blur event added to input fields. It re-enables zoom regardless of whether or not it was originally enabled. (line 5627)

.bind( "blur", function() {
    if( o.preventFocusZoom ){
        $.mobile.zoom.enable( true );

Temporary work-around if you don't want the user to be able to resize your page.

$.extend($.mobile.zoom, {locked:true,enabled:false})

Thanks for your suggestion.

Double tapping a text still zooms the entire screen a notch, though.
I. e. the $.mobile.zoom does not seem to have much effect?


That solved the problem for me. Do you have user scaling turned off?

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

Yes, exact same meta.
Add a couple of lines of text in a div that has some margin: After focus/blur of an input that text will be double-tap-able and zoom in


Weird. After clicking what is $.mobile.zoom.enable set to?

Have examined the issue further:
As you have pointed out, the problem is that all input blurs enables zooming and unlocks it with
$.mobile.zoom.enable( true );
Patching this solves the problem.


Amazing find . This one solved the issue for me . Thanks

This worked for me too. Thanks!

This issue has been fixed by commit b8c5e45.
However, we noticed that on iOS5 when the font-size is set to anything smaller than 1em/16px (i.e. data-mini="true") the browser still zooms in. This has been fixed in iOS6.

Closing as fixed.
