页面展开还有创建两个控件，Button 和 TextBox，单击按钮后 TextBox 出现 tip 提示，并获得焦点（focus），TextBox 事件 keyup 则关闭 tip，代码如下：

{
// 创建一个输入框
var myTextBox = new dijit.form.TextBox({
name : "firstname",
value : "" /* no or empty value! */,
placeHolder : "type in your name",
}, "textbox2");

// 设置 textbox keyup hide tip
on(myTextBox, "keyup", function()
{
var node = dom.byId('textbox2');
Tooltip.hide(node);
});

// 创建一个按钮
var myButton = new Button({
label : "Click1",
onClick : function()
{
console.info('button1 onclick');

// button onClick show tip
var node = dom.byId('textbox2');
Tooltip.show("tooltip & focus, keyup hide me.", node);

// focus textbox2
dojo.byId("textbox2").focus();
}
}, "button1").startup();

});
</script>
