问题 I'd like to give my users the ability to log-in my Android app using their OpenId (have a text field like StackOverflow's and ask the user to enter his OpenId there). I've looked around a lot but could not find any libraries that allow me to implement Client-Side OpenId authentication on Android. Should I rather go for server side authentication - ie. authenticate through my own website and pass the control to the application once the authentication is done? Thanks, Abhinav 回答1: http://code

问题 I am forseeing a problem with allowing customers who purchase some content from me via PayPal. I will offer multiple, intangible goods. When someone completes their purchase for one of these goods, they will be redirected to a landing page - let's call it "thank_you.php" - which will automatically queue up a download and allow a link to queue up download in case it doesn't start automatically. This will be done by passing the unique item ID to the download page ("download.php"). This method

问题 What I want to do is make a dropdownlist choices change depending on other dropdownlists on the page. What I did is write all the possibilities in hidden textboxes.

问题 I am writing a client-side validation function for CustomValidator and I need to check length of entered string. But before, to counteract cheaters a little, I want to remove all leading and trailing spaces from the string. What is the easiest way to do it in this scenario? Thank you! 回答1: The easiest way is to call the ValidatorTrim(value) javascript function on your page. This function comes from the javascript that every asp.net validator includes when added to a page. But i don't think

问题 Is it possible to write a string to a file (create the file if it doesn't exist) without any external Javascript libraries , purely with Javascript code ? I'm trying to implement a client side code that whenever it reaches a page (.ASPX) it writes few strings into a file (let's say output.txt ) and that's it .
