基于验证的Ag-Grid树状结构在NodeChildren单元上附加cellClass

Question

在我的Jquery&JavaScript，Angular，所有独立的应用程序中，我都包含了带有columnDefs的Ag-Grid，如下所示：

 this.columnDefs = [
  {
    headerName: "Age",
    field: "age",
    cellRenderer: "agGroupCellRenderer"
  },
  {
    headerName: "Name",
    field: "name"
  },
  {
    headerName: "Year",
    field: "year"
  },
  {
    headerName: "Country",
    field: "country"
  }
];

我的行数据如下

 this.rowData = [
  {
    age: "Group A",
    participants: [
      {
        age: 1,
        name: "Michael Phelps",
        year: "2008",
        country: "United States"
      },
      {
        name: "A.2",
        age: 2,
        year: "2008",
        country: "United States"
      },
      {
        name: "A.3",
        age: 50,
        year: "2008",
        country: "United States"
      }
    ]}];

this.getNodeChildDetails = function getNodeChildDetails(rowItem) {
  if (rowItem.participants) {
    return {
      group: true,
      children: rowItem.participants,
    };
  } else {
    return null;
  }

现在我想将cellClass附加到基于验证的子网格值，例如：

 if(age< 23 || ''){
  return['classNameThatiWantToAttach'];
 }

如何做到这一点？

你也可以在下面的柱塞器中进行更改：

Answer 1

你可以这样做

编辑列定义并向其中添加cellClass函数

 {
    headerName: "Year",
    field: "year",
    editable: true,
    cellClass: this.cellClass
  }

然后定义函数并添加所需的条件，并返回一个包含类的值的字符串

  cellClass(params) {
    if (params.value >= 2015)
      return "redClass"
  }

不要忘记为这些类添加css样式。

请参阅更新后的plunkr，根据年龄验证，显示为红色的单元格：

this.columnDefs = [
    // ...
    {
        headerName: "Age",
        field: "age",
        cellClassRules: this.getCssClass()
    }
    // ...
];

getCssClass(): {[cssClassName: string]: (Function | string)} {
    return {
        'invalid-age': this.validateAge(),
    };
}
