AngularJS element onresize event - Custom Directive

问题

Does AngularJS have equivalent to this:

elementObject.addEventListener("resize", myFunction);

I thought about about watches, but I don't think it's the good solution.

回答1:

Create a custom directive:

app.directive("myResize", function($parse) {
    return {
        link: postLink
    };
    function postLink(scope, elem, attrs) {
        elem.on("resize", function (e) {
            var rs = $parse(attrs.myResize);
            rs(scope, {$event: e});
            scope.$apply();
        });
    }
});

Usage:

<div my-resize="$ctrl.myFunction($event)">
</div>

You can also do this: HTML:

<div resize-me></div>

JavaScript:

myApp.directive('resizeMe', ['$window', function($window) {
    return {
        link: function(scope, elem, attrs) {
            angular.element(elem).bind('resize', function() {
                //do something on resize
            })
        }
    }
}])
