Kendo网格，ko绑定以及对行索引的访问 [英] Kendo grid, ko binding, and access to row index

问题描述

我有一个ko视图模型，该模型使用剔除-kendo.js绑定到KendoGrid

I have a ko viewmodel, which I bind to a KendoGrid, using knockout-kendo.js

我使用rowTemplate，因为在某些列(图标，链接等)中需要一些自定义功能

I use rowTemplate, because I need some custom functionality in some columns (icon, links, etc)

我需要基于行号执行一些自定义功能.

I need to do some custom functionality based on rownumber.

当直接绑定ko viewmodel时，我可以使用foreach绑定，并且在行模板中有$ index，它可以为我提供当前行号.

When binding ko viewmodel directly, I can use foreach binding and in the row template I have the $index which gives me the current row number.

当将视图模型绑定到Kendo网格时，我怎么能得到相同的东西?

How can I get the same thing when the viewmodel is bound to a Kendo Grid?

谢谢

推荐答案

当前在Kendo-Knockout模板中没有内置的索引功能支持(在本机Kendo模板中也没有对此的支持).

Currently there is no built in index functionality support in the Kendo-Knockout the templates (also there is no support for this in the native Kendo templates).

不过，您可以结合使用 jQuery的index() 方法和$element绑定上下文获取数据网格中当前tr位置的属性(尽管如果使用分页，这将无法正常工作):

However you could use the jQuery's index() method in combination with the $element binding context poperty to get the current tr position inside the datagird (altough this does not work correctly if you using paging):

<div data-bind="kendoGrid: { data: items, rowTemplate: 'rowTmpl', 
                             useKOTemplates: true }"> </div>

<script id="rowTmpl" type="text/html">
    <tr>
        <td>
            Row index: 
                <span data-bind="text: $($element).closest('tr').index()"></span>
        </td>
    </tr>
</script>
