如何在extjs小部件列中获取rowIndex [英] How to get rowIndex in extjs widget column

问题描述

我需要一个小部件列中的按钮来在ExtJS 6 panel.grid中了解其rowIndex，以便在按钮上单击它可以使用该功能。我知道我可以从渲染器函数中拉出这些信息，但这似乎在按钮被创建之前执行。任何有关如何获取索引的想法？

I need a button in a widget column to know its rowIndex in an ExtJS 6 panel.grid, so that on button click it can use that functionality. I know I can pull that information from the renderer function, but that seems to execute before the button has been created. Any ideas on how I can get the index?

推荐答案

使用 indexOf 在 gridview 上。您需要将节点作为参数传递，该参数是表示行的HTML元素。在Ext JS 6中，网格行是HTML表格，因此可以从按钮元素 b 中找到按钮的行元素作为 b.el.up（ '表'）。 gridview 也可以找到为 b.up（'gridview'）。所以你得到：

Use indexOf on the gridview. You need to pass it the node as argument, which is the HTML element representing the row. In Ext JS 6, grid rows are HTML tables, so the button's row element can be found from the button element b as b.el.up('table'). The gridview can also be found as b.up('gridview'). So you get:

var rowIndex = b.up('gridview').indexOf(b.el.up('table'));
