I'm struggling to produce results to the screen from the following code: HTML: <script src="http://code.jquery.com/jquery-2.1.4.js"></script> <script src="http://code.jquery.com/ui/1.11.4/jquery-ui.js"></script> <script src="../scripts/autocomplete.js"></script> <div> <input type='text' class='search_input' name='search' id='search' placeholder='search' autofocus onkeypress='search_func("http://webfarm.io/subs/homefront/list_articles.php" , "search_output")'> <div id='search_output' class='search_output'></div> </div> Javascript: function search_func( href , target){ var search = $("#search").val(); search = $.trim(search); if(search){ $.ajax({ method: "POST", url: href , data: { search: search } }) .done(function( msg ) { target.innerHTML = msg; // as above, data holds the result of the request, so all the data returned from your results.php file are in this param but please see below; console.log(msg); }); } else { target.innerHTML = ''; } } What am I doing wrong? Why won't it produce the desired results? Sorry if I'm looking like a help vamp, but I'm not trying to be.

<input id="numb" type="number" /> <input type="submit" onclick="myFunction()" /> <p id="demo"></p> <script> function myFunction(){ var x = document.getElementById('numb').value; var regex=/^[1-9]+$/; if (x == ""){ document.getElementById('demo').innerHTML = "Input is Missing"; } else if (!x.match(regex)){ document.getElementById('demo').innerHTML = "Input Incorrect"; } else { document.getElementById('demo').innerHTML = "Input OK"; } } /* if (x == "") { document.getElementById('demo').innerHTML = "Input is Missing"; } else if (isNaN(x)) { document.getElementById('demo').innerHTML = "Input Incorrect"; } else { document.getElementById('demo').innerHTML = "Input OK"; } } */ </script> When input type is "text" it works fine. but when i change input type to "number" and then if i type letters or letters plus numbers. it says "input missing" How can i get correct output while using input type "number" ? Please guide. Thankyou.

Is there away to get something unique on a client computer? I read about ActiveX but it is only works on IE. I need something that can work on other browsers also, maybe on PHP or on Javascript.

Hi all, I need some guidance on how I can build an AJAX/PHP chat application, sort of like an instant messaging thing like the one on Facebook. It doesn't have to be anything fancy as long as it works. I have some ideas as to how I can build it but I've never tried to do anything like this before so I'm a bit lost. I'm confident I can build the entire PHP side of things up until I have to use AJAX, then I'm stuck. The main concern I have is the affect it will have on the server, lets say I have a Javascript timer to check for new messages sent at certain intervals, wouldn't that have a massive affect on the server? I can only think of using a timer to get new messages for each user, I can't come up with any other way to get it to work. I just don't want to kill the server with AJAX requests if that's even possible. So really my question is, would it be okay to use a timer to get new messages of each user at certain intervals, or is there another way of doing it? Hope this makes sense Thanks, Adam
