我想知道如何通过点击Vuetify数据表中的一行来选择/取消选择一行。如果我可以通过使用shift+点击或shift+箭头来选择一个范围,那就更好了,但这是另一个问题了。
我已经尝试更新发送到参数“value”中的数组,但是在用户界面中从未选中这些行。
<template>
<v-data-table
:headers="headers"
:items="desserts"
item-key="id"
class="elevation-1"
:value="selectedRows"
@click:row="rowClicked"
></v-data-table>
</template>
<script>
export default {
data() {
return {
selected: [],
selectedRows: [],
headers: [
{
text: "Dessert (100g serving)",
align: "left",
sortable: false,
value: "name"
},
{ text: "Calories", value: "calories" },
{ text: "Fat (g)", value: "fat" },
{ text: "Carbs (g)", value: "carbs" },
{ text: "Protein (g)", value: "protein" },
{ text: "Iron (%)", value: "iron" }
],
desserts: [
{

}
]
};
},
methods: {
rowClicked(row) {
this.swapSelectionStatus(row.id);
this.log(row);
},
swapSelectionStatus(keyID) {
if (this.selectedRows.includes(keyID)) {
this.selectedRows = this.selectedRows.filter(
selectedKeyID => selectedKeyID !== keyID
);
} else {
this.selectedRows.push(keyID);
}
},
select(e) {
this.log(e);

log(logItem) {
/* eslint-disable no-console */
console.log(logItem);

我认为您应该使用
v-model
来代替...Demo
您还可以使用Vuetify Data Table
select
函数来切换所选行,这比使用自定义方法来处理选择逻辑要容易。Demo 2
rekjcdws2#
这样做,它就会工作得很好。
请注意两点:v-model和show-select接下来,在脚本的数据部分添加selected数组
puruo6ea3#
您可以更改它,并删除
single-select
属性,最后,您还需要通过在row.select(true)
中使用row.isSelected
而不是true
来使行可切换您可以在下面找到完整的解决方案,对于单选,请查看顶部的链接https://codepen.io/deadManN/pen/RwBKLpv
我也要感谢Nicolai Nikolai的回答,因为没有它,我就不知道有一个行参数,所以我不能调试它以查看它的额外属性
<style scoped>
,则还需要在scoped
CSS样式中使用/deep/
或::v-deep
,以便能够覆盖Vuetify样式
