ExtJS 数据网格列渲染器具有多个值 [英] ExtJS Data Grid Column renderer to have multiple values

问题描述

我想知道是否可以在 ExtJS 中为列的渲染器提供多个数据源值.例如对于Actions"列，id 被传递给渲染器.但是我需要将 user_id 和 id 传递给渲染.我该怎么做?

I am wondering if it is possible in ExtJS to have several values of the data source available to the renderer of the column. For example with the "Actions" column, the id is passed to the renderer. However I require both the user_id and id passed to the render. How may I do this?

table_cols = [{
    header: "User ID",
    width: 30,
    sortable: true,
    dataIndex: 'user_id'
},
{
        header: "Actions",
        width: 60,
        sortable: false,
        dataIndex: 'id',
        renderer: function(val) {
               //IF USER ID MEETS A CONSTRAINT PRINT THE ID
         }
}];

谢谢.

推荐答案

据我所知renderer函数有几个参数:

As far as I know renderer function has several parameters:

     renderer: function(val, meta, record) {
           var userId = record.data.user_id;
     }

你可以查看docs 所有参数
