titanium开发教程0208创建文本域和多行文本输入区

var win = Titanium.UI.createWindow({
	title:"Creating Text Fields and Text Areas",
	backgroundColor:"#FFFFFF",
	exitOnClose:true
})

//
var textField1 = Titanium.UI.createTextField({
	top:60,
    height:60,
    300,
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED, //This is a constant that can be used to style textfields in iOS
    hintText:"This text is called hintText" //Hint text is displayed to the user before the field has been edited
});

//
var textField2 = Titanium.UI.createTextField({
	top:180,
    height:60,
    300,
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED, //This is a constant that can be used to style textfields in iOS
    hintText:"This is called hintText" //Hint text is displayed to the user before the field has been edited
});

//A Text Area is similar to a Text Field except that it will allow multiple lines of text entry
var textArea = Titanium.UI.createTextArea({
    value:"Text displayed to the user before entry", //This text will remain in place when the user begins to enter text
    height:150,
    300,
    top:250,
    suppressReturn:false,//Use this property to allow the return key to function as a line-return key and not a blur-keyboard key
    borderWidth:1,
    borderColor:"#CCC",
    borderRadius:12
});

textArea.addEventListener("focus",function(e){
	//Wipe out the default text on initial focus
	if(e.value == "Text displayed to the user before entry"){
		e.source.value = "";
	}
});

textArea.addEventListener("blur",function(e){
	//Restore the defaut text if on blur there is no text in the text area
	if(e.value == ""){
		e.source.value = "Text displayed to the user before entry";
	}
});

//Add an event listener to the window that allows for the keyboard or input keys to be hidden if the user taps outside a text field
//Note: each text field to be blurred would be added below
win.addEventListener("click", function(e){
	textField1.blur(); // Cause the text field to lose focus, thereby hiding the keyboard (if visible)
	textField2.blur(); // Cause the text field to lose focus, thereby hiding the keyboard (if visible)
	textArea.blur(); // Cause the text area to lose focus, thereby hiding the keyboard (if visible)
});

win.add(textField1);
win.add(textField2);
win.add(textArea);

win.open();
