用url传递参数时后面多出字符会是什么原因？

HTML code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$prev = $page - 1;echo "<a id="submitbuttons" href="menu_icon.php?page=%22.%24prev.%22'">上一页</a>";
Copy after login

结果点击“上一页”时url是GET http://localhost/test/html/test.php?page=1%27，而且到上一页后虽然页面上的元素都能显示，但是不再执行JS了。这是什么原因？

------解决方案--------------------
仔细看你的url

href=……' 引号部分

%27，恰好是'
------解决方案--------------------
echo "上一页";
