表格高亮

这个是我在蓝色里看到的,果果写的表格高亮,效果本身没什么,只是觉得他的写法很牛屮,所以记录一下,可能在以后的效果中借签一下他的思路。

JS:

function Fx(el, over, hot) {
	var els = document.getElementById(el).getElementsByTagName("tr"), el2, el3,
	del = function(el, css) {
		el.className = el.className.replace(eval('/\\b' + css + '\\b/ig'), '');
		//注意这里的return
		return el;
	},
	add = function(el, css) {
		if (el.className.indexOf(css) == -1) el.className += ' ' + css;
		return el;
	};
	for (var i = 0; i < els.length; ++i) {
		el = els[i];
		el.onmouseover = function() {
			//这里是亮点,这句里的el2记录上一个onmouseover对象,和下一句的el2已经不是同一个了
			if (el2) del(el2, over);
			el2 = add(this, over);
		};
		el.onmouseout = function() {
			del(this, over);
		};
		el.onclick = function() {
			//类似前面的onmouseover
			if (el3) del(el3, hot);
			el3 =add(this, hot);
		};
	};
};
