在angular2中实现addClass和removeClass功能 [英] implement addClass and removeClass functionality in angular2

问题描述

我有几个用于ListView和GridView的按钮.为了在这两个按钮之间切换，我编写了如下的JQuery-

I have couple of buttons for ListView and GridView. For switching between these 2 buttons I had written JQuery like below-

<script type="text/javascript">
    $(document).ready(function () {
        $("button.switcher").bind("click", function (e) {
            e.preventDefault();
            var theid = $(this).attr("id");
            var theitems = $("ul#items");
            var classNames = $(this).attr('class').split(' ');
            if ($(this).hasClass("active")) {
                // if currently clicked button has the active class
                // then we do nothing!
                return false;
            } else {
                // otherwise we are clicking on the inactive button
                // and in the process of switching views!
                if (theid == "gridview") {
                    $(this).addClass("active");
                    $("#listview").removeClass("active");
                    // remove the list  view and change to grid
                    theitems.removeClass("tilelist");
                    theitems.addClass("gridlist");
                }

                else if (theid == "listview") {
                    $(this).addClass("active");
                    $("#gridview").removeClass("active");
                    // remove the grid view and change to list
                    theitems.removeClass("gridlist")
                    theitems.addClass("tilelist");
                }
            }

        });
    });
</script>

现在，我想将此功能从Jquery移至Angular2打字稿应用程序.有人可以在这方面指导我吗?如何从angular2模板上单击按钮实现addClass和removeClass功能?

Now I want move this functionality from Jquery to Angular2 typescript application. Can anyone please guide me on this? How do I implement addClass and removeClass functionality on button click from angular2 template?

推荐答案

如果要在component.ts中使用它

If you want to due this in component.ts

HTML:

<button class="class1 class2" (click)="clicked($event)">Click me</button>

组件:

clicked(event) {
  event.target.classList.add('class3'); // To ADD
  event.target.classList.remove('class1'); // To Remove
  event.target.classList.contains('class2'); // To check
  event.target.classList.toggle('class4'); // To toggle
}
