I have tested the input[type=\"search\"] and it does not show the clear (x) icon when the bootstrap styles have been applied.
To have the same user experience across all devices, I ended up writing an Angular directive that I put on Bootstrap 'input-group-btn's.
Angular view HTML
{{vm.models.listSearchResults.length}}
/
{{vm.data.list.length}}
Angular directive JavaScript
.directive( 'clearSearchByAria', ['$parse', function clearSearchByAria( $parse )
{
return(
{
'restrict':'A',
'link':function clearSearchByAria_link( scope, jqElem, ngAttr )
{
jqElem.on( 'click', function( $event )
{
var $clickedElem = angular.element($event.currentTarget);
var $searchInput;
// Specified by selector.
if( !!ngAttr.clearSearchByAria )
{
var $specifiedElem = angular.element(ngAttr.clearSearchByAria)
if( $specifiedElem.length == 1 )
{$searchInput = $specifiedElem;}
}
else
{
var $describedElem = $clickedElem.find( '[aria-describedby]' ).addBack( '[aria-describedby]' );
// Specified by 'aria-describedby'.
if( $describedElem.length == 1 )
{$searchInput = angular.element(''.concat( '#', $describedElem.attr('aria-describedby')));}
else
{
throw( new ReferenceError( "'clear-search-by-aria' attributes requires either 1) to be empty and for the element (or a descendant) to have an 'aria-describedby' attribute referring to another element or 2) to specify an element selector (e.g. '#id') to another element." ));
}
}
if( !!$searchInput && $searchInput.length == 1 )
{
var ng_model = $searchInput.data( 'ngModel' ) || $searchInput.attr( 'ng-model' );
if( !!ng_model )
{
var modelGetter = $parse( ng_model );
modelGetter.assign( scope, '' );
scope.$apply();
}
else
{
$searchInput.val( '' );
}
}
});
},
});
}])`
