【问题描述】:
我正在尝试实现handsontable。根据我的要求,我想通过更改下拉值重新渲染handsontable,但是在下拉选择中,handsontable 无法正确更新。以下是我的代码:
Handsontable.vue:
<template>
<div id="hot-preview">
<HotTable :settings="settings" :ref="referenceId"></HotTable>
<div></div>
</div>
</template>
<script>
import { HotTable } from '@handsontable-pro/vue';
export default {
components: {
HotTable
},
props: ['settings', 'referenceId'],
}
</script>
<style>
#hot-preview {
max-width: 1050px;
height: 400px;
overflow: hidden;
}
</style>
父组件:
<template>
<div id="provisioning-app">
<v-container grid-list-xl fluid>
<v-select
:items="selectList"
item-text="elementName"
item-value="elementName"
label="Standard"
v-model="selected"></v-select>
<handsontable :settings.sync="settings" :referenceId="referenceId"></handsontable>
</v-container>
</div>
</template>
<script>
import Handsontable from '@/components/Handsontable';
import PrevisioningService from '@/services/api/PrevisioningService';
export default {
components: {
Handsontable
},
data: () => ({
selectList: [],
selectApp: [],
selectedOption: '',
referenceId: 'provision-table',
}),
created(){
PrevisioningService.getProvisioningList(this.$session.get('userId'), this.$session.get('customerId')).then(response => {
this.provisioningList = response;
});
},
beforeUpdate() {
this.provisioningApp = this.getProvisioningAppList;
},
computed: {
settings () {
return {
data: this.getSelectApp,
colHeaders: ["Data Uploaded on", "Duration in Minutes", "Start Time", "Shift","Description","Next Day Spill Over", "Site Name"],
columns: [
{type: 'text'},
{type: 'text'},
{type: 'text'},
{type: 'text'},
{type: 'text'},
{type: 'text'},
{type: 'text'}
],
rowHeaders: true,
dropdownMenu: true,
filters: true,
rowHeaders: true,
search: true,
columnSorting: true,
manualRowMove: true,
manualColumnMove: true,
contextMenu: true,
afterChange: function (change, source) {
alert("after change");
},
beforeUpdate: function (change, source) {
alert("before update");
}
}
},
getSelectApp () {
if(this.selectedOption !== undefined && this.selectedOption !== null && this.selectedOption !== ''){
PrevisioningService.getProvisioningAppList(this.selectedOption, this.$session.get('userId'), this.$session.get('customerId')).then(response => {
this.provisioningApp = response;
return this.provisioningApp;
});
}
}
},
method: {
getSelected () {
return this.selectedOption;
}
}
};
</script>
通过上面的代码,我的数据成功从服务器接收到了,但是我无法更新handsontable中的数据,如下截图所示:
