How to insert text into the input of a page loaded in a webView?

Question

Java

Good afternoon. Decided to load a web resource in a webView. Now I'm trying to find a specific input and insert text into it, but so far without success. Has anyone experienced this and how did you resolve the issue?

Answer 1

not with android but on java, javafx.scene.web.WebEngine (as I understand it is also used on android)
take the webEngine.getDocument() document to it, you can make requests like getElementById or getElementsByTagName, in general, almost all the same methods that are available in javascript (querySelector is not directly available), as a result you will get access to elements like org.w3c.dom.html.HTMLImageElement / HTMLInputElement and so on. which will have methods for setting value values ​​or simply accessing attributes by name.
Click emulation is also available directly from java, but I strongly recommend that everything that should call methods inside the browser in javascript be done by calling webEngine.executeScript, and if it is difficult to reach the element by its identifier (for example, it has neither a name nor an identifier), but you were able to get it object in java, you can pass it back to javascript like this:
final static string GET_NODE_TEXT = "unique_node_name";
...
// after page load
htmlWnd = (DOMWindowImpl)((DocumentView)htmlDoc).getDefaultView();
...
// an example of calling submit a form whose element we have in node
htmlWnd.setMember(GET_NODE_TEXT, node);
browser.executeScript("(function(){var x=window."+GET_NODE_TEXT+";x.form.submit();})()");
