JS修改CSS的三种方式？
<html>
<head>
<style type="text/css">
.newDiv {
font-weight: bold;
}
</style>
<script>
function clk(event) {
var parent = document.getElementById("parent");
//改变className
var child0 = document.createElement("div");
child0.innerHTML = "child0";
child0.className = "newDiv";
parent.appendChild(child0);
//改变cssText
var child1 = document.createElement("div");
child1.innerHTML = "child1";
child1.style.cssText = "font-weight: bold";
parent.appendChild(child1);
//改变直接样式
var child2 = document.createElement("div");
child2.innerHTML = "child2";
child2.style.fontWeight = "bold";
parent.appendChild(child2);
}
</script>
</head>
<body>
<input type="button" value="click" onclick="clk(event);"/>
<div id="parent">
<div>child</div>
</div>
</body>
</html>PS:
