Detailed explanation of Vue event handling and event modifiers

 <div id="root">
        <h2>Keep going, {{name}}! </h2>
        <!-- Prevent default events -->
        <a @click.prevent="showInfo" href="https:www.baidu.com">Click me for prompt information</a>
        <!-- Prevent event bubbling -->
        <div class="demo1" @click="showInfo">
            <button @click.stop="showInfo">Click me for information</button>
        </div>
        <!-- Event is triggered only once -->
        <button @click.once="showInfo">Click me for information</button>
        <!-- Use event capture mode -->
        <div class="box1" @click.capture="showMsg(1)">
            div1
            <div class="box2" @click="showMsg(2)">
                div2
            </div>
        </div>
        <!-- The event is triggered only when event.target is the element currently being operated on -->
        <div class="demo1" @click.self="showInfo">
            <button @click="showInfo">Click me for info</button>
        </div>
    </div>
