Dojo 事件未触发
我有一个 Dojo 选项卡容器，当我单击某些按钮时，会动态添加一个新选项卡，其内容是通过 Ajax 下载的。这些选项卡包含动态表单元素，Dojo 可以很好地解析和加载这些元素。我还包括特定于每个选项卡的 Javascript 块，并且这些块也通过 Ajax 下载...但是，没有一个 Javascript 块执行！
选项卡内容示例：
<input id="test" name="test" type="text" dojoType="dijit.form.ValidationTextBox" />
<script type="text/javascript">
dojo.connect(dijit.byId('test'), 'onClick', function(evt){
alert('testing 123');
});
</script>
但是，如果我这样做，事件触发就好了：
<input id="test" name="test" type="text" dojoType="dijit.form.ValidationTextBox">
<script type="dojo/method" event='onClick'>
alert('testing 123');
</script>
</input>
我的问题是，为什么第一个示例中的 Javascript 块不起作用？这是 Dojo 的限制吗？另外，我还尝试在加载小部件后设置它们的属性和值。鉴于我必须使用诸如 dojo.addOnLoad() 之类的东西，我该如何激活它，它不起作用，因为它需要一个 Javascript 块，并且按照第一个示例不起作用......没有等效的小部件 onLoad 事件，所以我也不能使用第二种方法...有什么想法可以做到这一点吗？
I have a Dojo tab-container and when I click on certain buttons, a new tab is added dynamically with its contents downloaded via Ajax. The tabs contain dynamic form elements which are parsed and loaded by Dojo just fine. I am also including Javascript blocks which are specific for each tab and those are downloaded as well via Ajax... however, none of the Javascript blocks execute!
Example of tab content:
<input id="test" name="test" type="text" dojoType="dijit.form.ValidationTextBox" />
<script type="text/javascript">
dojo.connect(dijit.byId('test'), 'onClick', function(evt){
alert('testing 123');
});
</script>
However, if I do this instead the events trigger just fine:
<input id="test" name="test" type="text" dojoType="dijit.form.ValidationTextBox">
<script type="dojo/method" event='onClick'>
alert('testing 123');
</script>
</input>
My question is, why don't Javascript blocks in the first example work? is this a Dojo limitation? Also, I am also trying to set properties and values for the widgets AFTER they've been loaded. How do i active that given I have to use something like dojo.addOnLoad() which won't work because it requires a Javascript block and that doesn't work as per the first example... There is no equivalent widget onLoad event so I can't use the second method either... Any ideas how to go about doing this?

“选项卡内容”实际上是一个内容窗格元素。除非使用
更新：如果您使用
dojox.layout.ContentPane而不是dijit.layout.ContentPane，所有与其中的js有关的问题都会消失。来自 Dojo 参考指南：The "tab content" is actually a Content Pane element. You can't call a javascript inside a content pane unless you use
<script type="dojo/method">. At least this is what I know.Update: ifyou'll use
dojox.layout.ContentPaneinstead of thedijit.layout.ContentPaneall the problems regarding the js inside it will vanish. From Dojo Reference Guide:看起来您需要使用 dojo.hitch 以便您的函数在实际调用时位于范围内。尝试使用：
您可以在这里阅读更多相关信息：http://dojotoolkit。 org/reference-guide/dojo/hitch.html#dojo-hitch
It looks like you need to use dojo.hitch so that your function will be in scope when it is actually called. Try using:

您必须确保首先解析该小部件。这样做：
You have to ensure that the widget has been parsed first. Do it like so :
