var canvas, stage, w = window.innerWidth, h = window.innerHeight; function init() { //设置canvas属性 canvas = document.getElementById('game'); canvas.width = w; canvas.height = h; //建立舞台 stage = new createjs.Stage(canvas); //绘制居中文字 var text1 = new createjs.Text("Hello World", "20px Arial", "#ff4400"), bounds = text1.getBounds(); text1.x = stage.canvas.width - bounds.width >> 1; text1.y = stage.canvas.height - bounds.height >> 1; //绘制左边文字 var text2 = new createjs.Text("Hello World", "20px Arial", "#ff4400"); //绘制右边文字 var text3 = new createjs.Text("Hello World", "40px Arial", "#ff4400"), bounds = text3.getBounds(); text3.x = w - bounds.width; //下居中文字 var text4 = new createjs.Text("Hello World", "20px Arial", "#ff7700"), bounds = text4.getBounds(); text4.x = stage.canvas.width - bounds.width >> 1; text4.y = stage.canvas.height - bounds.height; stage.addChild(text1); stage.addChild(text2); stage.addChild(text3); stage.addChild(text4); stage.update(); }
1:绘制舞台类canvas
createjs.Stage(canvas HTML)
2:绘制文字类spa
createjs.Text('text', 'font-size font-family', '#color')
3:得到文字边界属性code
Text.getBounds();
其中包含的属性有: width,height等;get
4:添加到舞台it
stage.addChild(displayObject);
5:更新画板显示出来io
stage.update();
6:追加 居中的另外一种方式function
//居中文字另外一种方法 var text5 = new createjs.Text("Hello World", "20px Arial", "#ff7700"); text5.textAlign = 'center';//以自身的位置居中,本身的宽度,0 width/2,width text5.x = stage.canvas.width / 2;
