关于php代码控制前台div显示的问题
需求如下:
网站html页面中动态读出了若干产品,产品有选择功能,勾选中的产品会保存在session中
现在在php代码中,已经获取了session中保存的ID,形式如“1,2,3,4,...”
希望在页面再次刷新时,已经保存在session中的这些ID自动勾选上
希望高手可以提供思路。

目前我困惑在两点:1.在php代码页面,如何遍历html页面中产品的ID,并使其div的样式为block
2.如果通过js去做,我如何将这串获取的ID传递给js呢

------解决方案--------------------
这种操纵div 显示什么的还是通过js/jquery来完成吧。

2.如果通过js去做,我如何将这串获取的ID传递给js呢

你所说的ID传递是说php传递给js吗?

最简单的方式

echo "";

?>

然后用js 读取这个input 的value 再切割字符就出来了.接着操作div 的block
------解决方案--------------------
从session中取值,做字符串切割处理,然后你可以用jquery ajax传到js,在处理显示,或是var a= ' ';session aaa的值设置为“1,2,3,4,5,6,7,8”,然后你在javascript中分割显示
