我正在为tumblr页面进行动态布局。到目前为止，我已经成功地为css样式表做了一个时间敏感的开关，但现在我也要切换横幅。
我掀起了一些代码（javascript）来执行此操作，但不断收到错误并且不知道原因。我也不确定准确放置代码的位置。由于这是一个tumblr布局，标题位于开始标记的正下方。所以我不确定我是否应该在那里放置javascript，或者我应该将它放在标签下面
这是我提出的代码。它在DW中给我一个语法错误，但由于我是新手，我不知道问题是什么。
<script type="text/JavaScript">
<!--
function getHeader() {
if (7 <= currentTime&¤tTime < 18) {
document.write("<h1><a href="/"><img src="http://itsnotch.com/tumblr/images/NotchTheGuru_VCbanner.jpg" border "0" /></a></h1>");
}
else {
document.write(" <h1><a href="/"><img src="http://itsnotch.com/tumblr/images/NotchTheGuru_Banner.jpg" border "0" /></a></h1>");
}
}
getHeader();
-->
</script>
它在'document.write'行上给出了一个错误。
以下是该页面的完整源代码，可让您更好地了解我正在做的事情
