Dijit TabContainer事件 - onFocus

Question

我有一个Tab容器，当我点击一个标签的标题栏时，我想执行一些js。

我似乎无法弄清楚如何添加一个事件。

编辑：

它看起来像我将使用onFocus，但我仍然无法找到正确的语法。

编辑：找到onFocus and onBlur，但仍然无法正常工作。

Answer 1

您需要连接到_transition事件。

var tabs = dijit.byId("tabs"); 
dojo.connect(tabs,"_transition", function(newPage, oldPage){ 
    console.log("I was showing: ", oldPage || "nothing"); 
    console.log("I am now showing: ", newPage); 
}); 

其中“tabs”是您的TabContainer。

下面是一个完整的代码示例，在道场1.8工作，我测试过它：

require(["dijit/registry", "dojo/on", "dojo/ready", "dojo/domReady!"], function (registry, on, ready) { 
    ready(function() { //wait till dom is parsed into dijits 
     var panel = registry.byId('mainTab'); //get dijit from its source dom element 
     on(panel, "Click", function (event) { //for some reason onClick event doesn't work 
      alert(panel.selectedChildWidget.id); 
     }); 
    }); 
});

正确的道场1.7+应该的;

var tabs = registry.byId('someTabs'); 
tabs.watch("selectedChildWidget", function(name, oval, nval){ 
    console.log("selected child changed from ", oval, " to ", nval); 
}); 

另一种方式可能是

var tabs = registry.byId('someTabs'); 
aspect.after(tabs, "selectChild", function (event) { 
    console.log("You selected ", tabs.selectedChildWidget.id); 
});
