如果您查看我的演示代码,您将看到一个名为scrollToCurrentMonth()的函数,它试图滚动到ListTemplate中具有'current'类的元素。 我的问题是我无法获得这个元素,因为它已经通过vue.js插入到dom中。 那么,我如何获得这个元素与类'current',以便我可以得到它的顶部位置为滚动动画呢?
null
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;
}

</div>

尝试使用mounted而不是created。
null
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(),
};
},
mounted() {
this.scrollToCurrentMonth();
},
methods: {
scrollToCurrentMonth() {
$('.list-wrap').animate({
scrollTop: $('.list-wrap .current').offset().top
}
}
}
});
new Vue({ el: "#app" });
.list-wrap {
max-height: 300px;
overflow-y: scroll;
}
.event_month {
height: 100px;
border: 1px solid;
}
