获得id为week的按钮 点击按钮的时候,希望按钮增加多个类名,jquery好实现,那js除了这样一个一个的加还有没有比较方便的方法么?<script> window.onload = week; function week(){ var weeks = document.getElementById("week");
var table = document.getElementById("table"); var table2 = document.getElementById("table2");
var text = document.getElementById("text");
table2.className = fix;
weeks.onclick = function(){
weeks.className = 'show';
weeks.className = 'week';
table.className = 'fix';
}
text.change = function(){
weeks.className = 'fix';
weeks.className = 'week';
table.className = 'show';
}
}
</script>
