</table>请教,这样也不行,要让js执行,一般都是放到什么地方呀?还有<script>
window.onload=function(){
document.writeln("ddd");
};
</script>这段代码是放在html语言里面什么地方呀?head前面吗?body里面呀?
ie,ff测试均通过
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>test</title>
<script>
window.onload=function(){
alert("onload start...");
document.writeln("ddd");
};
</script>
</head><body>
<table width="600" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#0000FF">
<tr>
<td colspan="4" bgcolor="#FFFFFF" class="FileHead">地震观测报告
<script>
alert("first write...");
document.writeln("ddd");
alert("second write...");
document.writeln("ddd");
</script>
</td>
</tr>
</table>
</body></html>
