img.src = "SChart.aspx?now="+ now +"sqlWhere ="+encodeURIComponent(_sqlWhere);
img.src = "SChart.aspx?now="+ now +"sqlWhere ="+encodeURIComponent(_sqlWhere);
为什么SChart.aspx页面取不到sqlWhere的值？
string sqlWhere = System.Web.HttpContext.Current.Request.QueryString["sqlWhere"];

[解决办法]
img.src = "SChart.aspx?now="+ now +"&sqlWhere ="+encodeURIComponent(_sqlWhere);

_sqlWhere 看看他有没有值呗

加了空格可能就被当作字符串处理了吧？

那你获取的就不能是“sqlWhere”而是“sqlWhere ”
