javascript - 如何使用 FlashCC 和 CreateJS 制作展开式广告？

Question

我想知道如果我以 300x250 开始制作 Flash HTML5 Canvas 横幅，如何才能使其向下展开页面并扩展 Canvas 尺寸？

Answer 1

试试这个:

var originalHeight = this.stage.canvas.height;
var expandedHeight = 300;  // Put here your desired height
this.stage.addEventListener("mouseover", mouseOverHandle);

function mouseOverHandle() {

    this.stage.canvas.height = expandedHeight;
    this.stage.addEventListener("mouseleave", mouseLeaveHandle);
    this.stage.removeEventListener("mouseover", mouseOverHandle);
}
function mouseLeaveHandle() {
    this.stage.canvas.height = originalHeight;
    this.stage.addEventListener("mouseover", mouseOverHandle);
    this.stage.removeEventListener("mouseleave", mouseLeaveHandle);
}

您会看到一些闪烁，因为 Canvas 在调整大小时重新绘制其内容。请参阅此问题以获取更多信息 Flickering during resizing of HTML5 canvas
