Using Jquery inside AngularJS directive good or bad idea?

问题

Below you can see my code for the directive.

My question is: " Can i use jquery with directives? Is that a good idea? If not why? "

outsource.directive('dedicated', function(){

        return {
           restrict: 'E',
           link: function(scope, element, attribute){

                 $("#klik").click(function(){
                    alert('works');
                 });

           },

           replace: true,
           templateUrl: 'src/app/components/views/dedicated-prices.html'
        };
    });

P.s this code works.

You should not be using jquery as Angular itself has a lighter version for it known as jqlite.

More documentation on JQLITE

So your directive should look like:

outsource.directive('dedicated', function(){

    return {
       restrict: 'E',
       link: function(scope, element, attribute){

             var elem = angular.element(document.querySelector('#klik'))
             angular.element(elem).triggerHandler('click');

       },

       replace: true,
       templateUrl: 'src/app/components/views/dedicated-prices.html'
    };
});

Simple Answer: YES (Simply refer jquery.js above Angular.js in HTML page. jqLite will be replaced by jQuery)

You would be using jQuery for DOM manipulation & there are many discussions going on this topic (whether to use or not in modern browsers).

One of the popular posts in the recentdays: http://lea.verou.me/2015/04/jquery-considered-harmful/

Despite everything, jQuery is still a very popular, highly used DOM library. And, it works with many modern UI frameworks seamlessly.

Interesting question. I've got some jquery with element selection in some directives/controllers in my codebase.

I always feel dirty using it and only do it when I really need to, unfortunately it's almost always a time bomb and leads to me cursing myself a few months down the line and refactoring to use a more angulary method.

Have one last look to see if there's a native angular way of doing what you're trying to do, you won't regret it!
