  • How can I refresh a page via jQuery and ensure that there's a connection?

    - by Steve
    Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later. I'm using the jQueryTimers plugin. this is my code so far: //reload trigger $(document).everyTime('60s', 'pagerefresh', reloadPage, 0, true); //refresh function function reloadPage() { $.ajax({ url:'index-1.php', type:'HEAD', success: location.reload(true) }) } I have no idea how to tell jQ what I want. any hint appreciated.

  • Best way to do client/server validation in ASP.NET in 2010?

    - by punkouter
    First there was the ASP.NET validators and we used them... Then some people on the team did things manually in javascript... Then a bunch of jquery validation libraries came out... Then MVC2 came out with attributes as validators.. I work with apps that have alot of forms with alot of various validation (Some fields needs to be compared with other values in a DB so a postball/ajax call is required) .. Right now I have a mess of ASP.NET custom validators and functions that calculate on the server side as well. Can I get some opinions on the best tool/combination to approach this job that can create the smallest/most elegant code? Pure server side solution? AJAX/Jquery? A certain plugin for jquery? For example, I have 2 dates.. I want to make sure that the 1st date is less than the 2nd date... Are there jquery validators that encapsulate this? My feeling is if I can get jquery plugins to handle half the more basic validation for my that could cut my code in half.

  • Jquery ajax get - how to output data based on condition?

    - by arunas_t
    Hello, there, I have a such piece of code: $("#choose").change(function(){ $.get("get_results.php", {name: $("#choose").val()}, function(data){ if(data !== ""){ $("#results").html(data); }else{ $("#results").html('<strong>Sorry, no records.</strong>'); } }); }); Now the problem is that the first condition ( if(data !== "") ) is always evaluated correctly and executed, but the else clause ('Sorry, no records') never shows up. Can anyone spot the error? Data passed for the else clause is specifically "". Thank You.

  • Web UI prototyping tools

    - by AlexKelos
    Can anyone recomend me a simple web UI prototyping tool, so I could quicky prototype the look of a my web site. I have tried to use MS Visio for this, but found it very "user un-friendly". What I really need is to be able quicky sketch the layout of the page, put some links, images and buttons on in, play a little bit with a colors (CSS), and it would be great it this tool could support navigation between the pages - but it is not essential. I would rather consider a low-cost or an open-source solution, since I am not a web designer and not going to use that tool on a daily basis.

  • Error message: "$(window).width is not a function"

    - by Crippletoe
    Hi all, i am trying to use a jQuery scrollbar called "Jscrollhorizontalpane". when i am trying to use it i get the following error message: "$(window).width is not a function" in firebug's console. i am new to jQuery do this might be very basic but still, i dont know what that means and why there is a problem. the scroller comes in a bundle with a few files, one of which is called "jScrollHorizontalPane.js" and i believe it holds the code for the scroller. i tried replacing $ signs there with the word "jQuery" (in case there is a conflict) but it didnt seem to help. also important to add that on the same page i am using another jQuery scroller (a vertical one as opposed to the horizontal on mentioned above) which works just fine and when i examined it's .js file, i could spot lines with "$(window).width". any ideas?

  • Jquery .html replacer just empties my selector, what's wrong!?

    - by jphenow
    $("#autoNames").html(function (index, html) { var begin = "<script language='javascript' type='text/javascript'> var names = ["; var end = String('];' + '<' + '/' + 'script' + '>'); var result = begin.concat(jsonService, end); $("#autoNames").html(result); return false; }); I can't figure out for the life of me why this doesn't work. I've gotten the html function to work before, but for some reason this just leaves my autoNames tag empty... and i've called an alert() on the result variable and things exist in that string... any clues? Thanks

  • (jquery): After Ajax: success, how to limit parsing in pieces and insert piece by piece into the DOM

    - by Johua
    Let's say on ajax success the function: xmlParser(xml) is called and the XML response contains about 1500 xml elements (for example: ...) Inside it looks like: function xmlParser(xml){ var xmlDOM = $(xml); // dom object containing xml response xdom.find("book").each(function(){ var $node = $(this); // parsing all the <book> nodes }); } How can you say: parse only first 20 nodes from the xml response, do something with them. And you have a button,..when clicked parses the next 20 nodes...and so on. So bassically, is there something like: children(20)....and a function wich will parse the next 20 nodes onClick. thx

  • Overriding CSS style 'display:none' in javascript

    - by jsarma
    I'm trying to add a checkbox toggle that hides and shows list elements by changing their style display attribute from "none" to "inline", but it's not working. I'm setting the attribute's style to "display:none" in the CSS file. Then I set it to "display:inline" in javascript when someone checks a box. The javascript is successfully changing the element's property to inline, but for some reason the element remains invisible. If I do the opposite, by setting the display to inline in the CSS and overriding it to none in the javascript, it works fine. I don't see why this would work one way but not the other. I'm using chrome. Here is the code. Any feedback is appreciated. CSS file: #tabmenu li[status='disabled'] a, a.active, #disabled { color: #777777; background: #DDDDDD; font: normal 1em Arial; border: 1px solid black; border-radius: inherit; padding: 0px 5px 0px 5px; margin: 0px; text-decoration: none; cursor:hand; display:none; } HTML: <ul id="tabmenu"> <li name='tab' id='tab1' selected='no' status='disabled'></li> </ul> JAVASCRIPT (from command line, or onchange of a checkbox) tab = document.getElementById('tab1'); tab.style.display = 'inline';

  • InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

    - by marcinn
    The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)

  • best method in jquery for replacing rows in a table after server side processing such as mysql sorti

    - by Kevin J
    What is the 'best practice' when returning dynamic data for a table (server side sorting, filtering etc from a db) ? Do you return just the data in json, and repeatedly clone a row element, replacing the values in each row (thus decreasing the size of the ajax call, but increasing the client side processing), or return the full html, and replace with .html or .append? Or is there another method I'm missing? This is a frequent situation in my app, and in some cases a bottleneck, and I am unsure if what I am doing is the best solution. Currently, I return the row html and use a single .append call, after emptying all the rows except the header.

  • jQuery - How to determine if a parent element exists?

    - by Dan
    Hi, I'm trying to dynamically and a link to an image, however I cannot correctly determine is the parent link already exists. This is what I have, if (element.parent('a'.length) > 0) { element.parent('a').attr('href', link); } else { element.wrap('<a></a>'); element.parent('a').attr('href', link); } Where element refers to my img element and link refers to the url to use. Every time the code runs, the else clause is performed, regardless of whether or not the img tag is wrapped in an a tag. Can anyone see what I'm doing wrong? Any advice appreciated. Thanks.

  • jquery XML, i need .html() not .text() but not working?

    - by Xtian
    I need var long to be exported as html and not text. I know I have .text() but when I use .html() it will not work. Also if I take the .text() out when declaring the variable and it will not work in IE? The reason for this is, in the XML certain words will have html tags like or and I need those to be recognized. I thought I solved it when I took out .text() but then i looked at IE and I got nothing. $(document).ready(function(){ $.ajax({ type: "GET", url: "xml/sites.xml", dataType: "xml", success: function(xml) { $(xml).find('site').each(function(){ var id = $(this).attr('id'); var title = $(this).find('title').text(); var class =$(this).find('class').text(); $('<div class="'+class+'" id="link_'+id+'"></div>').html('<h2>'+title+'</h2>').appendTo('#page-wrap'); $(this).find('desc').each(function(){ var long = $(this).find('long'); var url = $(this).find('url').text(); $('<div class="long"></div>').html(long).appendTo('#link_'+id); $('<a href="http://'+url+'"</a>').html(url).appendTo('#link_'+id); }); }); } }); });// JavaScript Document

    I have a page with news item titles, clicking each one ajax loads a full news items including a photo thumbnail. I want to attach a lightbox to the thumbnails to show a bigger photo. I have two options (i think): .live() . $('img .thumb').live('click', function()) add a specific id based listener on callback of the news item click . $('div.news_item').click(function(){ var id = $(this).attr('id'); //click show_news_item(), //callback function(){$(id+' .thumb').lightbox();} })

    - by mna
    hi, I'd like to bind an event to a class, or any alternative to the redundant code I posted below. Any ideas? thanks, mna (function(){ $( "button", "body" ).button(); var submenu=false; $( "#about" ).click(function() { $( "#content" ).fadeOut(1000); $( "#content" ).load('about.html'); $( "#content" ).fadeIn(1000); }); $( "#community" ).click(function() { $( "#content" ).fadeOut(1000); $( "#content" ).load('community.html'); $( "#content" ).fadeIn(1000); }); $( "#store" ).click(function() { $( "#content" ).fadeOut(1000); $( "#content" ).load('store.html'); $( "#content" ).fadeIn(1000); }); $( "#projects" ).click(function() { $( "#content" ).fadeOut(1000); $( "#content" ).load('projects.html'); $( "#content" ).fadeIn(1000); }); });
