为何DIV嵌套在JS代码后不能实现广告与文章混排
在文章中调入a.js文件，调用代码为
<script type="text/javascript" src="http://www.51skill.cn/jsforad/articletop.js"></script> 后面加文章内容代码
a.JS文件代码如下：
[code]
document.writeln("<div style=\"float:left;width:336px;height:280px;\">");
document.writeln("<script type=\"text\/javascript\"><!--");
document.writeln("google_ad_client = \"pub-50262898418895229\";");
document.writeln("\/* 336x280, 创建于 08-5-13 *\/");
document.writeln("google_ad_slot = \"1784659134\";");
document.writeln("google_ad_width = 336;");
document.writeln("google_ad_height = 280;");
document.writeln("\/\/-->");
document.writeln("<\/script>");
document.writeln("<script type=\"text\/javascript\"");
document.writeln("src=\"http:\/\/pagead2.googlesyndication.com\/pagead\/show_ads.js\">");
document.writeln("<\/script>");
document.writeln("<\/div>");
[/code]
这样不能实现文字与广告混排的形式，而且上面还留一大部分空白，不知到为何？
如修改成下列形式就可以：
<div style="float:left;width:336px;height:280px;">
<script type="text/javascript" src="http://www.51skill.cn/jsforad/articletop.js"></script>
</div>
Js代码如下：
[code]
document.writeln("<script type=\"text\/javascript\"><!--");
document.writeln("google_ad_client = \"pub-50262898418895229\";");
document.writeln("\/* 336x280, 创建于 08-5-13 *\/");
document.writeln("google_ad_slot = \"1784659134\";");
document.writeln("google_ad_width = 336;");
document.writeln("google_ad_height = 280;");
document.writeln("\/\/-->");
document.writeln("<\/script>");
document.writeln("<script type=\"text\/javascript\"");
document.writeln("src=\"http:\/\/pagead2.googlesyndication.com\/pagead\/show_ads.js\">");
document.writeln("<\/script>");
[/code]
请问是什么原因，改如何修改才能实现，谢谢！ |
