ExtJS Data Grid Column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ExtJS中是否有可能对列的渲染器提供数据源的几个值。例如，使用操作列，将id传递给渲染器。然而，我需要传递给渲染的user_id和id。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，渲染器函数有几个参数：

As far as I know renderer function has several parameters:

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

您可以查看 docs 的所有参数
