ウィンドウを震わせる

JavaScript

var movie = 5,    // 震える大きさ
    time  = 2000; // 震える時間

var shakeBtn = document.getElementById('shake');

if (!shakeBtn) return;

var isIE = navigator.userAgent.match(/MSIE/i);

// ボタンクリック時イベント
shakeBtn.onclick = function() {
	this.disabled = true;

	var self      = this,
	    win       = isIE ? window : window.open('about:blank', null, 'width=200,height=200'),
	    startTime = Date.now(),
	    count     = 1;

	var sid = setInterval(function() {
		if (count === 1) {
			win.moveBy(0, movie);
		} else if (count === 2) {
			win.moveBy(movie, 0);
		} else if (count === 3) {
			win.moveBy(0, -movie);
		} else {
			win.moveBy(-movie, 0);
			count = 0;
		}

		count++;

		if (Date.now() - startTime >= time) {
			clearInterval(sid);
			self.disabled = false;

			win.close();
		}
	}, 10);
};
