通过将值传递给setSquare()函数，脚本更容易阅读和理解。

window.onload = initAll;

function initAll () {
	for (var i = 0; i < 24 ; i++) {
		setSquare(i);
	}
}

function setSquare(thisSquare){
	var currSquare = "square" + thisSquare;
	var newNum = Math.floor(Math.random() * 75 ) + 1;

	document.getElementById(currSquare).innerHTML = newNum;
}
