在javascript中连接sqlserver数据库不是一个好主意，并且ActiveXObject仅在IE中有效.您应该尝试创建wcf服务，并从javascript代码中调用该服务，或者创建一个asp.net handler(ashx)，在两种情况下，您的响应都应为JSON或XML.如果要使用Javascript使用SignalR调用服务器功能，则还有第三种方法. SignalR中有一个主题涉及使用Javascript调用服务器端函数.

connecting sqlserver database in javascript is not a good idea , and ActiveXObject will only work in IE.You should try creating a wcf service and call that service from your javascript code, or create an asp.net handler(ashx) , in both cases your response should be in JSON or XML. There is also a third approach if you want to call the server function in Javascript use SignalR. There is a topic in SignalR about calling server side function in Javascript.
