如何設置在writeMessage()函數中顯示的文本的背景顏色? 下面是我的腳本的一部分。如何在動態js圖層中設置文本的背景顏色?
function initStage() {
var stage = new Kinetic.Stage({
container: 'somediv',
width: 565,
height: 570
});
var messageLayer = new Kinetic.Layer();
stage.add(messageLayer);
writeMessage(messageLayer, 'somemessage',300,300);
}
...
function writeMessage(messageLayer, message, xp,yp) {
var context = messageLayer.getContext();
messageLayer.clear();
context.setAttr('font', '20pt Calibri');
//how can i set background color of text here?
context.fillStyle = 'black';
context.fillText(message, xp, yp);
}
