lufylegend:文本、鼠标事件、键盘事件

1.文本

<script type="text/javascript">
init(50,"mylegend",500,350,main);
function main() {
   //创建层
   var layer = new LSprite();
   addChild(layer);
  //创建一个文本标签
   var field = new LTextField();
   field.text = "Hello World!";
   layer.addChild(field);
} 
</script>

<script type="text/javascript">
init(50,"mylegend",500,350,main);
function main(){ 
   var layer = new LSprite();
   addChild(layer);
   var field = new LTextField();
   field.x = 50;
   field.y = 50;
   field.text = "Hello World!";
   field.size = 25;
   field.color = "#333333";
   field.weight = "bolder";
   layer.addChild(field);
} 
</script>

2.文本输入框

<script type="text/javascript">
init(50,"mylegend",500,350,main);
function main(){ 
   var layer = new LSprite();
   addChild(layer);
   var field = new LTextField();
   field.x = 50;
   field.y = 50;
   //设置文本类型为输入框
   field.setType(LTextFieldType.INPUT);
   layer.addChild(field);
} 
</script>

3.鼠标事件

<script type="text/javascript">
init(50,"mylegend",300,300,main);
var field;
function main(){ 
   var layer = new LSprite();
   layer.graphics.drawRect(1,'#cccccc',[0,0,300,300],true,'#cccccc');
   addChild(layer);
   field = new LTextField();
   field.text = "Wait Click!";
   layer.addChild(field);
   //鼠标按下
   layer.addEventListener(LMouseEvent.MOUSE_DOWN, downshow);
   //鼠标抬起
   layer.addEventListener(LMouseEvent.MOUSE_UP,upshow);
} 
function downshow(event){
 field.text = "Mouse Down!";
}
function upshow(event){
 field.text = "Mouse Up!";
}
</script>

4.循环

<script type="text/javascript">
init(50,"mylegend",300,300,main);
var field;
function main(){ 
 var layer = new LSprite();
 layer.graphics.drawRect(1,'#cccccc',[0,0,300,300],true,'#cccccc');
 addChild(layer);
 field = new LTextField();
 field.text = "0";
 layer.addChild(field);
    //layer上绑定ENTER_FRAME事件，以帧速率调用onframe函数 
 layer.addEventListener(LEvent.ENTER_FRAME,onframe);
} 
function onframe(){
 field.text = parseInt(field.text) + 1;
}
</script>

5.键盘事件

<script type="text/javascript">
init(50,"mylegend",300,300,main);
var field;
function main(){ 
 var layer = new LSprite();
 layer.graphics.drawRect(1,'#cccccc',[0,0,300,300],true,'#cccccc');
 addChild(layer);
 field = new LTextField();
 field.text = "Wait Click!";
 layer.addChild(field);
 LEvent.addEventListener(LGlobal.window,LKeyboardEvent.KEY_DOWN,downshow);
 LEvent.addEventListener(LGlobal.window,LKeyboardEvent.KEY_UP,upshow);
} 
function downshow(event){
 field.text = event.keyCode + " Down!";
}
function upshow(event){
 field.text = event.keyCode + " Up!";
}
</script>

6.LButton

<script type="text/javascript">
init(50,"mylegend",300,300,main);
var loader,bitmapup,bitmapover,field; 
function main(){ 
    loader = new LLoader(); 
    loader.addEventListener(LEvent.COMPLETE,loadUp); 
    loader.load("up.png","bitmapData"); 
} 
function loadUp(event){ 
 bitmapup = new LBitmap(new LBitmapData(loader.content));
    loader = new LLoader(); 
    loader.addEventListener(LEvent.COMPLETE,loadOver); 
    loader.load("over.png","bitmapData"); 
}
function loadOver(){ 
 bitmapover = new LBitmap(new LBitmapData(loader.content));
 var layer = new LSprite();
 addChild(layer);
 field = new LTextField();
 field.text = "Wait Click!";
 layer.addChild(field);
 var testButton = new LButton(bitmapup,bitmapover);
 testButton.y = 50;
 layer.addChild(testButton);
 testButton.addEventListener(LMouseEvent.MOUSE_DOWN,downshow);
} 
function downshow(event){
 field.text = "testButton Click!";
}
</script>
