AngularJS Question

Select text on input focus

I have a text input. When the input receives focus I want to select the text inside of the input.

With jQuery I'd do it this way:

<input type="text" value="test" />




$("input[type=text]").click(function() {
$(this).select();
// would select "test" in this example
});


I've searched around to try and find the Angular way but most examples I'm finding are dealing with a directive that is watching a modal property for a change. I'm assuming I need a directive that is watching for an input that receives focus. How would I do that?

Answer

The way to do this in Angular is to create a custom directive which does the autoselect for you.

module.directive('selectOnClick', ['$window', function ($window) {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            element.on('click', function () {
                if (!$window.getSelection().toString()) {
                    // Required for mobile Safari
                    this.setSelectionRange(0, this.value.length)
                }
            });
        }
    };
}]);

Apply the directive like this:

<input type="text" value="test" select-on-click />

Update1: Removed jQuery dependency.

Update2: Restrict as attribute.

Update3: Works in mobile Safari. Allows selecting part of the text (requires IE>8).
