问题 I load a JavaScript file which takes current page's URL as a parameter. Here is the code I use: document.write(unescape('%3Cscript src=\"' + _vis_opt_protocol + 'domain.com/js.php&a='+account_id+'&url='+encodeURIComponent(document.URL)+'&random='+Math.random()+'\" type=\"text/javascript\"%3E%3C/script%3E')); I thought encodeURIComponent will do the job of properly encoding the URL. However, while loading JS file, browsers interpret the encoded URL too. For example if the document.URL is http:

问题 I've got an extended WebBrowser control which handles the NewWindow3 event. Originally I wanted this because it exposes the Url property. What I want to happen in this NewWindow event is to cancel opening a new IE instance (so I set E.Cancel = True). Then, I want to create a new form, a new web browser control and navigate to E.Url This sort of works. Where I'm running into problems, is with some JavaScript. If I navigate to a page that needs to access it's opener (in this case, to write to a

问题 I have a webbrowser object on a winform that I would like to use to display a pdf. The pdf resides on a ftp server. I have been able to show the pdf by downloading it to the disk and pointing the webbrowser object to it (navigate), but I want to stream it for security reasons.

问题 I have web application that uses WEB RTC for video communication between two peers. Everything works fine, but we have one headache in production. The thing is that when browser asks for camera and microphone permission, the pop up is often ignored by users and therefor they are getting frustrated why their video is not shown. So i am wondering if there is some library that can predict where the permission pop up is shown, so i can show some arrow from my html and make it more obvious? 回答1:
