Javascript和查询字符串问题

Question

当我在查询字符串中传递变量时，某些java脚本不显示。 只有当url看起来像这样.. default.aspx？yesId = 1 & noId = 27如果它只是default.aspx的Java脚本显示就好了。

你知道为什么吗？或者如何解决它？有没有另一种方式来发挥这个JavaScript代码？

Default.aspx的多数民众赞成在不显示的代码是在底部Div标签 “广告”

您可以创建这样的事情和测试请求/响应

HttpRequest q = Request; 
string v = q.QueryString["yesId"] 
    if (v != null) 
    { 
    } 
    v = q.QueryString["noId"]; 
    if (v != null) 
    { 
    }
