dojo datagrid事件附加问题 [英] dojo datagrid event attach issue

问题描述

我正在使用IBM Content Navigator 2.0.3，它使用DOJO 1.8进行GUI开发。我在dojo中是新的，我必须增强一种形式：在 dataGrid 中添加一个事件处理程序，所以当选择一个网格的一个按钮成为

I am working with IBM Content Navigator 2.0.3, that uses DOJO 1.8 for the GUI development. I am new in dojo, and I have to enhance one of the forms: add an event handler to the dataGrid so when the row of the grid is selected one of the buttons become enabled.

dataGrid 在HTML中描述如下：

dataGrid described in HTML as follows:

<div class="selectedGridContainer" data-dojo-attach-point="_selectedDataGridContainer">                     
    <div class="selectedGrid" data-dojo-attach-point="_selectedDataGrid" ></div>
</div>

并且控制表单行为的JS文件提到这个 _selectedDataGrid 只有一次，在 postCreate 函数中：

And the JS file that controls the form behavior mentioned this _selectedDataGrid only once, in the postCreate function:

postCreate: function() {
    this.inherited(arguments);
    this.textDir = has("text-direction");
    this.hoverHelpList = [];
    domClass.add(this._selectedDataGridContainer, "hasSorting");
    this._renderSelectedGrid();

_renderSelectedGrid（）正在执行，只包含以下内容：

_renderSelectedGrid() is being executed, which contains the only mention:

_renderSelectedGrid: function() {
    .......
    this._selectedDataGrid.appendChild(this._selectedGrid.domNode); 

我尝试添加一个数据dojo-attach-event onRowClick ：在HTML中的enableRemoveUsersButton 和

I've tried to add an data-dojo-attach-event onRowClick: enableRemoveUsersButton in the HTML and a

enableRemoveUsersButton: function(evt){
    this.removeUsersButton.set('disabled', true);
},

在js文件中。没有帮助。

in js file. Didn't help.

然后我试过：

dojo.connect(myGrid, "onRowclick", function update() {
    this.removeUsersButton.set('disabled', true); });

但我无法获取 myGrid 对象使用：

but I couldn't acquire myGrid object using:

`var myGrid  = dojo.byId("_selectedDataGrid");`

任何人都可以告诉我如何获取网格对象和/或向此网格添加事件处理程序，当选择网格的行时触发该事件处理程序

Can anyone tell me how to acquire the grid object and/or add an event handler to this grid, that fires when the row of the grid is selected?

谢谢！

推荐答案

我可以看到节点_selectedDataGrid只是一个Div标签。而您的dataGrid小部件可能是this._selectedGrid，因此您应该在该小部件上添加不是容器节点的事件。

From what you have share, I can see that the node "_selectedDataGrid" is just a Div tag. and your dataGrid widget may be "this._selectedGrid" so you should be add the event on that widget not the container node.

还有dijit.byId来获取dijits / widgets的实例。并且dojo.byId用于搜索dom节点。

Also there is dijit.byId to get the instance of dijits/widgets. and dojo.byId is used to search of dom nodes.

希望这是有帮助的。
