你可以使用 Vue 的 list rendering syntax 和 v-for:
<ELEMENT v-for="VARIABLE in ARRAY" :key="ITERATOR_ID">
在你使用<option>s 的情况下,你会得到这样的结果:
<option v-for="item in options" :key="item.id">{{item.label}}</option>
...其中options 是一个数据属性,包含这样的数组:
[
{ id: 1, label: 'A' },
{ id: 2, label: 'B' },
{ id: 3, label: 'C' },
]
如果您想要基于Department 的不同的<option>s 集合,您可以相应地将this.options 设置为不同的数组,数据绑定将自动更新<option>s:
methods: {
getOptions() {
const dept = this.Department;
if (dept === 'IT') {
this.options = [
{ id: 1, label: 'A' },
{ id: 2, label: 'B' },
{ id: 3, label: 'C' },
];
} else if (dept === 'Finance') {
this.options = [
{ id: 4, label: 'X' },
{ id: 5, label: 'Y' },
{ id: 6, label: 'Z' },
];
}
}
}
new Vue({
el: '#app',
data: () => ({
options: null,
Department: null,
selectedClient: null,
}),
methods: {
getOptions() {
this.selectedClient = null;
if (this.Department === 'IT') {
this.options = [
{ id: 1, label: 'A' },
{ id: 2, label: 'B' },
{ id: 3, label: 'C' },
];
} else if (this.Department === 'Finance') {
this.options = [
{ id: 4, label: 'X' },
{ id: 5, label: 'Y' },
{ id: 6, label: 'Z' },
];
}
}
},
})
