问题 I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one) <asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" /> <asp:TextBox ID="FromDate" runat="server" Columns="8"></asp:TextBox> <asp:TextBox ID="ToDate" runat="server" Columns="8"></asp:TextBox> <asp:CustomValidator ID="DateValidator" runat=

问题 I need to write a JavaScript module that rotates banner images displayed in a SharePoint web part. I would like to rely on SharePoint APIs as little as possible, and keep as much as possible self contained in the JavaScript module that drives the web part. I would like to keep track of the last time my code advanced to the next image in a list, and what that image was. The list will itself will be persisted in SharePoint and available through the REST API. So, in the modern browser JavaScript

问题 Why are browsers allowed to display source code for HTML/CSS/JavaScript files? I've been told that obfuscation is not the ultimate answer to provide protection. So once the code is sent to the client-side, anyone can steal the front-end data? Can't all popular browsers provide a password mechanism so that unauthorized users can't see the source code? Companies invest a lot of time, money, and other resources in developing professional sites, yet it seems there is a lot of business out there

问题 I am trying to upload the converted version of some image files on client-side with bootstrap-fileupload plugin for a custom view. In my search, I came up with this question, and pretty much figured out how to upload a file using a custom tag with ASP.NET. Now what I want to do is to resize that image file before the upload (as some image files may be > 15MP - which equals to > 5MB per file) to the server. Everyone is talking about Plupload, but that one has its own design interface and

问题 I want to run a thread pool on server side & want to show threads work progress on client side. Is this possible. If so kindly guide me. thanx in advance 回答1: Yes, in the main thread check for updates (or get notified by the worker threads) and then send the report progress over TCP Sockets (or using interprocess communications if on the same machine). On the client side parse the information when you receive it, and update the GUI/Progress accordingly. 来源： https://stackoverflow.com/questions

问题 Manytimes clients ask for features like instant messaging (IM) and other client-to-client (P2P) communication for their web apps. Typically how is this done in normal web browsers? For example I've seen demos of Google Wave (and Gmail) that are able to IM from a regular browser. Is this via HTTP? Or does XmlHttpRequest (AJAX) provide the necessary backend for such communication? More than anything I wonder how can a server "wake up" the remote client, lets say for sending an IM? Or does the

问题 I'm using Facebook's javascript SDK to inspect the friends list of users registered in my application.

问题 Is there any way of appending options to an asp.net dropdownlist control and viewstate at the same time?

At fist I was using AjaxControlToolkit CascadingDropdown control and it can do that but don't know how. any idea? 回答1: Appending options to a drop down list control will not reflect on the code behind, because you

问题 I am wondering if there is a way to make an image grayscale/b&w client side using javascript when the files are hosted on, say, AWS s3 or something. I have found this nice little script: http://www.permadi.com/tutorial/jsCanvasGrayscale/index.html But when you try to apply this to images that are not hosted on the same domain, you get a Security Error because you're performing cross-site operations. The exact error (from Chrome) is: Uncaught Error: SECURITY_ERR: DOM Exception 18 In particular
