这是我的父组件abc.vue

<v-card outlined class="mt-4">
        <DetailsTable v-show="toggleClientData" :columnDefs="columnDefs" :rowData="rowData" />
</v-card>
methods:{
aggridData() {
     let self = this;
      this.columnDefs = [
            {
              header:"name",
              field:"name",
              editable: true,
              onCellValueChanged: function(params) {
               self.updateClient();
              }
             }
           ]
      this.rowData = [{name:"abc",age:21},{name:"xyz",age:23}];
    },
 updateClient(){
   this.rowData[0].name = "cat"
 }
}

现在这是我的子组件DetailsTable.vue

<template>
  <ag-grid-vue
    style="width: 100%; height: 600px"
    class="ag-theme-balham"
    id="myGrid"
    :enableRangeSelection="true"
    :defaultColDef="{
              resizable: true,
              sortable: true,
              filter: true,
              width: 100
            }"
    :columnDefs="columnDefs"
    :processCellForClipboard="processCellForClipboard"
    :rowData="newRowData"
    :modules="[...agModule, ...agCModule]"
  ></ag-grid-vue>
</template>

<script>
import { AgGridVue } from "ag-grid-vue";
import "ag-grid-enterprise";
import { LicenseManager } from "ag-grid-enterprise";
import { AllModules } from "ag-grid-enterprise/dist/ag-grid-enterprise";
import { AllCommunityModules } from "ag-grid-community/dist/ag-grid-community";

LicenseManager.setLicenseKey(process.env.VUE_APP_AG_KEY);
import axios from "axios";

export default {
  name: "DetailsTable",
  props: {
    columnDefs: {
      type: Array,
      default() {
        return null;
      }
    },
    rowData: {
      type: Array,
      default() {
        return null;
      }
    }
  },
  components: {
    "ag-grid-vue": AgGridVue
  },
  data() {
    return {
      agModule: AllModules,
      agCModule: AllCommunityModules
    };
  },
  computed: {
    newRowData() {
      return this.rowData;
    }
  },
  beforeMount() {
    this.processCellForClipboard = params => {
      return `${params.value.trim()},`;
    };
  }
};
</script>

<style lang="sass" scoped>
@import "../../../node_modules/ag-grid-community/dist/styles/ag-grid.css"
@import "../../../node_modules/ag-grid-community/dist/styles/ag-theme-balham.css"
</style>

现在在开始时 newRowData 包含调用 updateclient 方法之前的 rowData 的值。一旦从 ag 网格表中更新了值,就会调用更新客户端函数,然后更改名称。现在,子组件中的 newRowData 显示了更新后的名称,即 cat,但这在表中没有更新。该表仍显示“abc”。在我下次单击 ag 网格单元格后,它会显示更新的值。有没有办法在不再次单击单元格的情况下显示更新的值我应该如何实现上述反应。

看起来您的反应性有问题。Vue 文档在这里详细讨论了反应性:https ://vuejs.org/v2/guide/reactivity.html

但是 TLDR,你不能像那样更新数组。你需要告诉 Vue 数组发生了变化。尝试

const theRow = this.rowData[0];
theRow.name = "cat";
Vue.set(this.rowData, 0, theRow)

您可能还需要使用Vue.set(theRow, 'name', 'cat')而不是theRow.name = "cat",但我并不积极。

此外,当 Vue 3 推出时,这将变得不那么困难 - 反应系统将需要更少的手动操作。

尝试更新整个数组:

  updateClient(){
//  this.rowData[0].name = "cat"        delete this line

    const updatedRow = {...this.rowData[0], name: "cat"}
    this.rowData.splice(0, 1, updatedRow)
  }
