问题 I'm wondering if it's normal. I add an option to a select with jQuery. When I save with an asp button, I don't see the changes on the server side in the click event. And the HTML is all correct after I add the option. Is it a coding problem or I don't understand something? :P $(selectCourant) .append($("<option></option>") .attr("value",$(dropdown).val()) .text($(dropdown + " option:selected").text())); Thank you ASP.NET And vb.net 回答1: Yes you did not understand something.

问题 If I have, say, an .aspx page that has a button called "btnProcess": asp:imagebutton id="btnProcess" onmouseover="src='siteart/addpayment2.gif'" tabIndex="13" onmouseout="src='siteart/addpayment1.gif'" Runat="server" Width="88" Height="22" ImageUrl="siteart/addpayment1.gif" AlternateText="Add Payment Button (CTRL + Plus(+))" With jQuery, if I wanted to link a function to that button when it's pressed, I could write something like this: $(document).ready(function () { $('#btnProcess').click

问题 For an web application I am working on I have the following requirements: Clients need to be able to log in via a web brower. After logging in, they will be able to change configurations (normal request/response) will be able to receive alarms sent by the server (a server side push) Now, the question is how to implement the alarms. I first thought of using some long polling approach (Comet), but as the amount of clients will definitely belimited to 5-10, I'm now thinking to go with a simpler

问题 I have a question about how to develop my web application security. Assuming that all the javascript code is public and that anyone can make any AJAX call directly, with parameters that seem convenient, then any call that directly modify the status of the database is highly dangerous. That is, calls as "changePoints" or "updateUserState" allow a malicious user to break the logic of, for example, a game and obtain unlimited money or points. My intuitive solution to this problem is to desing

问题 I've been working on an app which will feature a Timelinejs (open source js library) element on the client side. I copied the Timelinejs library into my public/javascripts/ directory of my app. Then I linked it in my html header. When I serve my app up locally everything works fine with the timeline. However, I noticed that when I deployed my app to Heroku it wasn't loading my timeline. Using chrome js console I discovered that it didn't find my files in the public/Javascripts/Timelinejs

问题 I'm a member of a team with more than 20 developers. Each developer works on a separate module. In each module, We load data only for the desired language.

C# Code var fileNumber = lblFileNumber.Text; string fileDownloadLink = "http://www.mysite.com/" + fileNumber + ".pdf"; string fileName = fileNumber + ".pdf"; bool exist = false; try { var

问题 Is there a pure .NET replacement for ActiveX? I'm asking if there is a way for me to write a thick client side control to be loaded and interacted with in a web page in .NET, with NO com. Edit: I don't want ActiveX in pure .NET, I want a .NET alternative to ActiveX. 回答1: I'm afraid there is no perfect managed only equivalent of ActiveX. Mostly for good reason. ActiveX is a dangerous technology security wise and duplicating it's effects in many ways would require duplicating the lack of
