问题 I'm trying to receive and potentially send complex values through TWebBrowser (using TEmbeddedWB) with the provided external object. For example; in javascript I would try to use the exposed method with an array as a parameter: var test = [123, 'abc']; external.someFunction(test); //Or something more complex var complexObject = { someMethod : function(){ return 1; }, someProperty : 123, someArray : ['xyz', 3.14] } external.someFunction(complexObject); Checking the VarType of both of these

问题 I have read the posts and the links about how to decode captcha. What I have not seen are strategies to make it more difficult to do this. In particular strategies that are not really complex. Also, does anyone have any strategies to try to detect if people are bypassing captcha? I am developing browser based game and I need to use something to prevent people from using simple bots to play all day long. There are actually companies out that that sell specialized bots for games. such as this

问题 I'm trying to load WebBrowser content and after that I want to add some text and scroll to the bottom. Here's example of my code: webBrowser1.Url = new System.Uri("file:///" + filePath); webBrowser1.Document.Body.InnerHtml += text; webBrowser1.Document.Body.ScrollTop = webBrowser1.Document.Body.ScrollRectangle.Height; When I run it, there's an unhandled exception "Object reference not set to an instance of an object".

问题 Can I close last opened tab (without closing the browser) from Python that was opened with the following code? import webbrowser webbrowser.get("firefox").open_new_tab(url) You can use whatever for this tasks.

问题 As you know, you can specify dimensions with CSS in px or em. As far as I understand it, em means "line height of the current element's fonts". My approach currently is to always use px (also for margin which seems to be a controversial practice). Question: Can I rely on the ratio of px and em to be the same across browsers ?

I was looking at the new wpf webbrowser control in the hope that they will have fixed this issue when doing a similar thing themselves, but can find no way to print from it.. I found someone online

问题 I'm searching for a way to let my users know that they have to log off when they are closing the window. I've already founded this code: window.onbeforeunload = confirmExit; function confirmExit() { return "It is better if you log out, before you close this page!"; } $(function () { $("a").click(function() { window.onbeforeunload = null; }); }); This works perfectly when I close my page. just as I want, but it also shows when I reload the page, which shouldn't happen.

问题 Are there any possible ways by which a malicious user on a web application can manipulate the input that is sent by the front-end of web application (not talking about the FORM DATA, of course) but the requests that are sent like for e.g., when I allow him to edit his profile or his content, he may manipulate the IDs (userId or the contentId) so that he may maliciously do evil with other users content? These inputs are fixed on a webpage & are not editable but still can the users manipulate

问题 I read an article about bookmarklets which says that bookmarklets are so powerful they can be dangerous. For example, a malicious bookmarklet can collect your "cookies", "localStorage", the string in the password input box and then send it to a remote server, which is similar to "script injection". I'm curious about that. Since this article was written in 2007 (8 years ago), is there any limitation for bookmarklets (as well as browser plugins) to improve the security in modern browsers? 回答1:
