WYSIWYG page configuration method, railway system construction method and device

The invention provides a WYSIWYG page configuration method and a railway system construction method and device.The method comprises the steps that a selection instruction for a target control in a target page is received, and a target component corresponding to the target control is searched for from components mapped between the controls; outputting all pre-stored rule objects corresponding to the target component to a target page and displaying the rule objects in a rule list form; and if a selection instruction for the target rule object in the rule list is received, analyzing the target rule object to correspondingly adjust the state of the target control in the target page and perform real-time preview. According to the method and the device, code-free configuration on the page in the software development process by business personnel can be realized, and the set interface effect can be immediately previewed, so that the software research and development cost can be effectively reduced, and the software
