Examples relate to manipulating web pages. In one example, a computing device may: receive a web page that includes application instructions for modifying objects included in the web page; execute the application instructions; record, in an ordered list of changes, change data for each application object that is modified, created, or destroyed during execution of the application instructions; record, in the ordered list of changes, change data for each web page object that is modified, created, or destroyed during execution of the application instructions; identify, in the ordered list of changes, a transition point between recorded changes; receive a request to change a state of the web page to the transition point; and apply, in reverse order, an inverse of each change specified in the ordered list of changes from a current point in time until the transition point.

Web page manipulation

Code implementing a full-duplex communication channel protocol within web browser software on a client computing device is replaced with replacement code. The replacement code intercepts incoming and outgoing messages on a channel opened at the web browser software between the client computing device and a server computing device running a web application. Responsive to the channel being opened at the web browser software, the replacement code intercepts and stores the incoming and outgoing messages.

Replacement code implementing full-duplex communication channel protocol for message interception

Examples herein involve a document object model (DOM) transaction crawler. Examples herein involve identifying an event in a first state of a document object model. The event is executed to cause a state change from the first state of the document object model to a second state of the document object model. Furthermore, the state change is stored in a transaction log to store the difference between the first state of the document object model and the second state of the document object model.

Document object model transaction crawler

In one example in accordance with the present disclosure, a method may include receiving an initial document object model (DOM) corresponding to an HTML page structure including a plurality of executable JavaScript code and simulating user interaction with an executable JavaScript code belonging to the plurality in the HTML page structure. The method may include adjusting the initial DOM based on the simulated user interaction, generating byte code corresponding to the adjust DOM and analyzing the byte code using a set of static rules.
