如何在 Angular 上为 ag-Grid 监听 sortChange(event)? [英] How to listen sortChange(event) on Angular for ag-Grid?

问题描述

我这里有一个非常基本的例子:https://stackblitz.com/edit/angular-ag-grid-angular-cwvpic?file=app/my-grid-application/my-grid-application.component.ts

在这个 ag-grid 中，我想打印哪一列点击并以何种方式排序.为此，我在官方文档中找到了方法 sortChange(event).但是我找不到实现这种方法的方法.这是我尝试的方法.

 sortChange(event){控制台日志(事件)；}<div style="width: 200px;"><ag-grid-angular(sortChange)="sortChange($event)"#agGrid style="宽度:100%；高度:200px；"class="ag-theme-fresh" [gridOptions]="gridOptions"></ag-grid-angular>

不幸的是，这不起作用.它什么也不打印.你知道我如何用列名监听每一列的排序变化吗?

解决方案

它是 sortChanged 而不是 sortChange(有一个 d).

试试:

 printSortStateToConsole() {const sortState = this.gridApi.getSortModel();如果(sortState.length == 0){console.log(没有排序活动");} 别的 {console.log("排序状态为:");for (var i = 0; i < sortState.length; i++) {const item = sortState[i];console.log(i + " = {colId: " + item.colId + ", sort: " + item.sort + "}");}}}onGridReady(参数:任何){this.gridApi = params.api;}

<ag-grid-angular#agGrid 样式=宽度:100%；高度:200px;"class="ag-theme-fresh";(sortChanged)="printSortStateToConsole($event)";(gridReady)="onGridReady($event)";[gridOptions]=gridOptions"></ag-grid-angular>

您的代码很好，但是您必须在网格准备就绪时填充 this.gridApi(结帐 (gridReady) 和 onGridReady).我知道你想通过这种方式登录到控制台.

I have very basic example here: https://stackblitz.com/edit/angular-ag-grid-angular-cwvpic?file=app/my-grid-application/my-grid-application.component.ts

In this ag-grid I want to print which column clicked and ordered in what way.To do that basically I found method sortChange(event) on official docs.But I couldn't find a way to implement this method.Here what I tried.

 sortChange(event){
      console.log(event);
    }

<div style="width: 200px;">
    <ag-grid-angular
     (sortChange)="sortChange($event)" 
     #agGrid style="width: 100%; height: 200px;" 
    class="ag-theme-fresh" [gridOptions]="gridOptions">
    </ag-grid-angular>
</div>

Unfortunately this didn't work.It prints nothing.Do you know how I can listen sort changes on each column with column name?

解决方案

It is sortChanged and not sortChange (has a d).

Try:

  printSortStateToConsole() {
    const sortState = this.gridApi.getSortModel();
    if (sortState.length == 0) {
      console.log("No sort active");
    } else {
      console.log("State of sorting is:");
      for (var i = 0; i < sortState.length; i++) {
        const item = sortState[i];
        console.log(i + " = {colId: " + item.colId + ", sort: " + item.sort + "}");
      }
    }
  }

onGridReady(params: any) {
      this.gridApi = params.api;
 }

<div style="width: 200px;">
    <ag-grid-angular
       #agGrid style="width: 100%; height: 200px;" 
       class="ag-theme-fresh"
       (sortChanged)="printSortStateToConsole($event)"
       (gridReady)="onGridReady($event)"
       [gridOptions]="gridOptions">
    </ag-grid-angular>
</div>

Edit: Your code is good, but you have to populate this.gridApi when the grid is ready like that (checkout (gridReady) and onGridReady). I get what you want to be logged into the console this way.
