I'm writing an app in phonegap with a specific 'zoom-in' effect when clicking on an input element (everything but the input hides and custom typeahead suggestions are shown). The view is written using backbone.js and i'm entering the 'zoomed-in' mode on focus:
events: {
'focus .search': 'startSearch',
}
In my startSearch
method i'm doing all the logic to immitate the zoom-in
effect.
_moveCursorToEnd: function(element) {
var val_len = element.value.length;
element.scrollLeft = val_len * 9;
setTimeout(function() {
element.selectionStart = val_len;
}, 1);
},
startSearch: function() {
window.navbar.hide();
this.$input.addClass('search-input-small');
this.$cancel.show();
var el = this.$input[0];
this._moveCursorToEnd(el);
},
The search-input-small
makes the input smaller.
The setTimeout
in _moveCursorToEnd
is required because the effect doesn't work otherwise. The issue is that despite setTimeout
having 1msec, it looks like a second cause inconvenient cursor move.
Is there any way to move the cursor to the end that would work on Safari Mobile 6 (iOS 6+) without the ugly delay?
I've ended up changing the event from focus
to click
and using similar code as mentioned above so that it works. Seems like the selection from a click that focused the text edit is applied after focus
handler and before click
handler.
