我做错了什么为什么div高度没有改变？提前致谢…
<html>
<head>
</head>
<body >
<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200px">Click Me!</button>
<div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>
</html>
解决方法
只是一个愚蠢的错误在’200px’中使用quote(”)
<html>
<head>
</head>
<body >
<button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px';">Click Me!</button>
<div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>
