我正在尝试通过使用内部总线事件中的vuetify来进行自动滚动,但这不起作用。我尝试通过单击事件(名为clicked
)在codepen上重现我的问题,我的行为相同:https://codepen.io/anon/pen/MLgRBz?&editable=true&editors=101
因此,我以文档中的滚动示例为例。我使用一个函数来触发click事件,并在其中将show变量设置为true,然后使用goTo函数进行滚动。 问题是,我必须单击两次按钮才能滚动,因为未创建DOM。我能怎么做 ?还有另一个事件要知道v-if指令何时创建元素?
const easings = {
linear: '',
easeInQuad: '',
easeOutQuad: '',
easeInOutQuad: '',
easeInCubic: '',
easeOutCubic: '',
easeInOutCubic: '',
easeInQuart: '',
easeOutQuart: '',
easeInOutQuart: '',
easeInQuint: '',
easeOutQuint: '',
easeInOutQuint: ''
}
new Vue({
el: '#app',
data () {
return {
type: 'number',
number: 9999,
selector: '#first',
selected: 'Button',
elements: ['Button', 'Radio group'],
duration: 300,
offset: 0,
easing: 'easeInOutCubic',
easings: Object.keys(easings),
show: false
}
},
methods: {
clicked: function() {
this.show = true;
this.$vuetify.goTo(this.target, this.options);
}
},
computed: {
target () {
const value = this[this.type]
if (!isNaN(value)) return Number(value)
else return value
},
options () {
return {
duration: this.duration,
offset: this.offset,
easing: this.easing
}
},
element () {
if (this.selected === 'Button') return this.$refs.button
else if (this.selected === 'Radio group') return this.$refs.radio
}
}
})
我尝试使用setTimeout在this.show = true
和this.$vuetify.goTo
之间进行操作,但是很丑陋
答案 0 :(得分:1)
显示内容后,您可以使用$nextTick
进行滚动:
clicked: function() {
this.show = true;
this.$nextTick(() => {
this.$vuetify.goTo(this.target, this.options);
});
}
