In any case, if the element ID is not found within the DOM (Document Object Model) of the webpage an error message will pop up, informing the user about the failure. Returning to the “WebsiteLogIn” macro, if the getElementById finds the user-input ID of the element, it will assign a value if the element is a (username/password) text box, or it will invoke the click method if the element is a (sign-in) button. The getElementById method was preferred in the particular case instead of other document object methods, such as getElementsByName, getElementsByTagName, and getElementsB圜lassName because the majority of web developers almost always assign unique ID values to the HTML elements of the web pages that they design.

But, how to find the element IDs so as to use this macro? Fortunately, with nowadays web browsers this is not a difficult task you just have to follow the next 7 steps: This information is user-input, along with the URL of the webpage, the username and the password for logging in. The getElementById method is used to find 3 elements on the target webpage: the username and password text boxes, as well as the sign-in button. One of the available document object methods, which is used in this example, is the getElementById method. The document object provides properties and methods to access all node objects (using JavaScript for example). The document object is the root node of the HTML document and the “owner” of all other nodes (element nodes, text nodes, attribute nodes, and comment nodes). So, let’s say a few HTML things: When an HTML document is loaded into a web browser, it becomes a document object. The other half code is dominated by the usage of the getElementById method, which returns a reference to an HTML element by using its ID. If yes, the procedure continues, otherwise, an error message pops up. Before the main procedure starts, the IsURLValid function is used to find if the target URL exists (see more about IsURLValid below). The ShowWindow API is used to maximize the Internet Explorer window. Since late binding is used, it is necessary to use the CreateObject method and ensure that the object was created. The macro creates a new instance of Internet Explorer, navigates to the desired webpage, enters the username and password values in the corresponding text boxes of the webpage, and, finally, presses the sign-in button in order to complete the log-in procedure.Īlmost half of the code of “WebsiteLogIn” macro is used to start a new instance of Internet Explorer and navigate to the requested URL. More precisely, I will analyze the concept behind a reusable macro that I developed. In this post, I will try to provide some insights into how to automate the log-in procedure via VBA. To be honest, web-related tasks can be considered as advanced VBA topics, since in many cases require basic knowledge of HTML language.
