好吧，对于你们许多人来说，我看起来似乎是一个非常愚蠢的问题，但我很难过。我正在研究一个有点过时的道场项目。部分内容已转换为AMD，部分内容尚未转换为AMD。这部分没有，所以请耐心等待。
我有一个用dgrid加载的页面，并且有一个dijit.Dialog的shell，但是隐藏在html标记中。页面上有一个编辑按钮，按下后，构建并填充对话框及其相关的dijits（通过旧的dojox.data.XmlStores选择，多选等，并使用所选网格行中的数据进行选择每个dijit中的正确数据。当构建dijit时，添加onChange事件。当在这些dijit中设置数据时，onChange事件触发。这是必需的。有时一个dijit的值需要改变另一个dijit＆＃ 39; s值......即使是第一次加载。但是，我有一些额外的javascript功能，它们与onChange事件相关联，并根据页面上的其他值设置字段值。这些不需要在第一个上运行完整加载对话框及其所有字段。
我认为这是我的代码的相关部分： HTML标记：
func PollEvents() {
for {
if event := sdl.PollEvent(); event != nil {
switch event.(type) {
case *sdl.QuitEvent:
utils.Running = false
}
} else {
break
}
}
}
使用Javascript：
<div class="dijitHidden">
<div data-dojo-type="dijit.Dialog" style="width:800px;text-align:left;" id="editDialog">
<table width='800px' cellpadding='25px' cellspacing='10px'>
<tr>
<td align="right"><From: </td>
<td align="left">
<div id="fromSelector"></div>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td align="right">Unit: </td>
<td align="left">
<div id="fromUnitSelector"></div>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td align="right">Room: </td>
<td align="left">
<div id="fromRoomSelector"></div>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td align="right">Mode: </td>
<td align="left" id="mode">
<div id="modeSelector"></div>
</td>
<td align="right">Priority:</td>
<td align="left" id="priority">
<div id="prioritySelector"></div>
</td>
</tr>
<tr>
<td></td>
<td></td>
<td align="right">Transporters: </td>
<td align="left" id="numSel">
<div id="numTranSelector"></div>
</td>
</tr>
<tr>
<td align="right">Type: </td>
<td align="left" id="type">
<div id="typeSelector"></div>
</td>
<td align="right">Comments:</td>
<td align="left" id="comment">
<div id="comments"></div>
</td>
</tr>
</table>
</div>
</div>
正如您所看到的，我有调用XmlStores的提取，并选择适用时在各个dijit中应选择的内容。我的问题是setAutoPriority（）和setAutoTransporters（）。我可以很容易地将一个变量传递给那些函数来告诉它是否是第一次加载......或者甚至将它们的调用包装在if语句中。我只是无法弄清楚如何告诉所有事情（用数据填充dijits并设置它们的值）。
任何想法都将不胜感激。到目前为止，我所做的一切都没有。而且仅供参考，根据所选网格行的数据，并非每一个dijit都会改变/每次都选择数据......这使得水更加混乱。
