在前端開(kāi)發(fā)中經(jīng)常見(jiàn)到隔行變色鼠標(biāo)移入高亮顯示的效果，下面小編給大家分享基于js代碼實(shí)現(xiàn)的隔行變色鼠標(biāo)移入高亮效果，廢話不多說(shuō)了，具體代碼如下所示：

for(var i = 0; i < table.tBodies[0].rows.length; i++) {
//使用判斷實(shí)現(xiàn)隔行變色
if(i % 2 == 0) {
table.tBodies[0].rows[i].style.backgroundColor = "gray";
} else {
table.tBodies[0].rows[i].style.backgroundColor = "#ccc";
}
//實(shí)現(xiàn)鼠標(biāo)移入高亮
