client-side

I have stumbled upon the issue when I need to retract html controls I've added client-side using JavaScript after the postback (due to server-side validation - this is not optional). Please tell me if the way I'm trying to achieve this is cr*p and there's a better way of doing this. basically, what I'm doing is cloning a textbox control for up to 10 times on the page when the user hits "Add" and storing entered values from each of those texboxes in a hidden field to read from in the code behind. This works fine, however, when the server side validation doesn't pass after postback, all those

Can I parse LESS client side, and return the results? I am currently using as recommended in documentation, which is to include less file, and minified less parser afterwards. I want to be able to return the raw css so I can save it as a css file. I do not want to install node.js and the likes, I want a client side solution. A look at the less.js source brings up the Parser object. Assuming that less.js is included in the page: var data = "@colour: red; #example { background-color: @colour; }", parser = new less.Parser({}); parser.parse(data, function (error, root) { // code that handles the

Is there any way to have some persistent data (like an XML file or so) apart from cookies at client side? I know that's not possible with JavaScript directly. But any other way like Applets or something?? Charlie Collins If cookies won't suffice, and you have to support older browsers, then LawnChair might help: http://brian.io/lawnchair/plugins/ It's like a "Couch" but smaller, get it? Took me a few minutes ;). And, it does work for desktop browsers, despite the blurb on the site about mobile-webkit: https://github.com/brianleroux/lawnchair/blob/master/README.md . (But, it uses cookies as the

Is it possible to find foreign instances of certain website? Ofc theese are independently opened tabs (not by window.open). I need to prevent user from opening 2 tabs, and send message to previously opened tab to inform that it's impossible to open 2 tabs. 2 Intependent tabs may break page offline storage and webSQL structure, so that I can't allow people to use 2 tabs. It's also semi-offline app so it needs to be client-side solution. You can communicate across tabs using localStorage. Every time you write a value, a "storage" event is fired on the window object on every tab (except the

How may I refresh current client view page from the server side? for example, if I want to force refresh for page that is viewing now for all the clients, so they can view the new content. and I want to do this refresh in the time that I want using PHP. Is it possible?? Use Web Sockets. You can use either PHP Sockets with this or this I think php Sockets would require you to have a PHP version of 5.3 or above. If you don't have PHP v5.3 or above you can use Node JS with Socket.io Long Pooling is also one of the option, but that won't be a good solution considering the number of requests your

This web page http://www.w3schools.com/ASP/prop_sessionid.asp states that a session ID is generated on the ServerSide. If this is the case, then how does a server know it's still the same client on the 2nd request response cycle? Surely the SessionId would be generated on the ClientSide so that the client would be sure of passing the same value to the server? The SessionID is generated Server Side, but is stored on the Client within a Cookie. Then everytime the client makes a request to the server the SessionID is used to authenticate the existing session for the client. The session ID is
