I need to read and write to an ActiveX control located in a broswer that accesses a mainframe. It is a simple command line interface (strictly text), and I believe it might be based on a citrix interface. I would like to be able to send a command and read via code the result. Can anyone give me some guidance on how to start this?

推荐答案

ActiveX控件是否已经存在，如果可以，那么可以使用API​​的描述吗?如果没有，您可以将其导入到win或控制台应用程序中，以至少获得智能.

否则，对象标签就是DOM的任何其他部分.您可以像其他任何元素一样通过其ID访问它.如果控件已成功加载(已安装且没有浏览器安全问题)，则可以像在任何win或控制台应用程序中一样使用它的方法和属性.我遇到了在加载页面后javascript会触发但控件尚未启动的问题.可以通过计时器设置回叫来轻松缓解这种情况.

Does the ActiveX control already exist, if so is a description of the API available for it? If not you can import it into a win or console app to at least get intellisence.

Otherwise the object tag is just any other part of the DOM. You can get access to it via it''s id like any other element. If the control is successfully loaded (both installed and having no browser security issues) then you can use it''s methods and properties as you would in any win or console app. I have encountered issues where javascript would fire after loading the page but the control had not yet initiated. This is easily mitigated by setting a call back via timer.
