有没有办法在Vue.js中动态插入点击事件?

Is there a way to dynamically insert click events in Vue.js?

尝试实现将一些计算方法插入到仅取决于移动视口的元素上。这是我正在使用的基本要点:

<a class="nav-link float-left p-x-y-16" v-bind:class={active:isCurrentTopicId(t.id)} @click="onTopicClicked($event, m, t)" href="#">{{t.title}}</a>

<script>

export default {
    data() {
        return {
            isClosed: false
        }
    },
    computed: {
        toggleMenu() {
            return {
                isClosed: this.isClosed
            }
        }
    },
    watch: {
        browserWidth(prevWidth, newWidth) {
            console.log('width changed from ' + newWidth + ' to ' + prevWidth);
    },
    mounted() {
        var that = this;
        this.$nextTick(function() {
            window.addEventListener('resize', function(e) {
                that.browserWidth = window.innerWidth;
                if(that.browserWidth > 824) {
                    console.log('Desktop View');
                } else {
                    console.log('Mobile View');
                }
            })
        })
    }
}
</script>

我想尝试使用调整大小事件来确定浏览器宽度,以便我可以动态地将计算函数插入到 <a> 标记

您可以添加说明视图是否移动的数据,并使用 v-if 、 v-else 并将 @click 仅添加到 v-if="isMobileView"

<a v-if="isMobileView" class="nav-link float-left p-x-y-16" v-bind:class={active:isCurrentTopicId(t.id)} @click="onTopicClicked($event, m, t)" href="#">{{t.title}}</a>

<a v-else class="nav-link float-left p-x-y-16" v-bind:class={active:isCurrentTopicId(t.id)} href="#">{{t.title}}</a>

<script>

export default {
    data() {
        return {
            isClosed: false,
            isMobileView: false
        }
    },
    computed: {
        toggleMenu() {
            return {
                isClosed: this.isClosed
            }
        }
    },
    watch: {
        browserWidth(prevWidth, newWidth) {
            console.log('width changed from ' + newWidth + ' to ' + prevWidth);
    },
    mounted() {
        var that = this;
        function checkIfMobileView() {
            that.isMobileView = window.innerWidth <= 824;
        }
        this.$nextTick(function() {
            window.addEventListener('resize', checkIfMobileView);
        });
        checkIfMobileView();
    }
}
</script>

您可以按照 Karthikeyan 的说明提供两种不同的元素(一种用于桌面设备,另一种用于移动设备),或者有条件地向该元素添加点击事件:

v-on="isMobileView ? { mouseover: onTopicClicked($event, m, t) } : {}"
