Question

我试图根据用户偏好更改货币格式，并从localStorage获取值。根据此链接https://docs.telerik.com/kendo-ui/knowledge-base/show-different-currencies-in-the-grid，我向kendo列模板引入了一个函数，该模板在Kendo列函数（函数getDefaultColumns）之外声明。

我的问题：用field: 'INVOICE_AMOUNT_ORIGINAL',编写的模板具有调用customCurrencyFormat的函数，但该函数未得到调用，因为在Visual Studio代码中，我可以看到警告“声明函数但未使用”。还有什么可能会使此功能到达列中的模板，或者做错了什么。

我正在尝试做的事情：我正在根据用户的喜好从本地存储中获取随机货币格式，我希望根据此更改网格列。（所有货币格式：欧元，英镑，美元...）任何其他方法也应受到赞赏

这是文件

    const columnNameList = GetLocalColumns(locale, type);
    const columnMap = this.defaultColumns.reduce((res, col) => {
      if (col) {
        const label = col.field_label || col.field;
        if (res[label]) {
          throw Error(`column ${label} declared twice`);
        }
        res[label] = col;
      }
      return res;
    }, {});
    // now the column configuration in the specified order
    const res = columnNameList.map((field) => {
      const col = columnMap[field];
      if (!col) {
        throw Error(`missing configuration for column ${field}`);
      }
      return col;
    });
    return res;
  }
}

module.exports = {
  ColumnCustomizer,
};
