【问题描述】:
如果您查看我的演示代码,您会看到一个名为 scrollToCurrentMonth() 的函数,它试图滚动到 listTemplate 中具有“当前”类的元素。我的问题是我无法获取此元素,因为它已通过 vue.js 插入到 dom 中。那么如何使用“current”类获取此元素,以便获得滚动动画的顶部位置?
const listTemplate = '' +
'<div class="list_body">' +
'<div v-for="(month, index) in months" v-bind:class="[\'event_month\', {current : index === currentMonth}]">' +
'{{month}}' +
'</div>' +
'</div>';
Vue.component('events-list-view', {
template: listTemplate,
data() {
return {
months: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
currentMonth: new Date().getMonth(),
};
},
created() {
this.scrollToCurrentMonth();
},
methods: {
scrollToCurrentMonth() {
$('.list-wrap').animate({
scrollTop: $('.list-wrap .current').offset().top
}, 2000);
}
}
});
new Vue({ el: "#app" });
.list-wrap {
max-height: 300px;
overflow-y: scroll;
}
.event_month{
height: 100px;
border: 1px solid;
}
