  • Which is the most memory leak safe approach.

    - by MattC
    I have a table of frequently updated information. This is presented using a container div with a div for each row, each row containing 10 divs. I am using setInterval to call a an asmx webservice that returns some json formatted information. On the success callback I call $("#myContainer").empty(); on the container div and recreate the rows and 10 nested divs for each row's columns. This page may be left to run for a whole day, so I am wary of updating the DOM like this as I have noticed that memory does rise for the browser over time (IE8). The other approach I am considering is to add an idea to the row div. When new results process each item of data, look for the corresponding row, if it exists overwrite the data in each div. If it doesn't exist (new data for example), append the row. What approaches have others used for this sort of long lived pseudo realtime information display. TIA

  • funny behavior of jquery code

    - by user253530
    Funny thing is that if i delete the comment for alert(data[i].id) the code works. As it is in the example, the string is not concatenated thus i have no options in the select box. Hints? Help? var bookmarkingSites = ''; $.getJSON("php/socialbookmark-get-bookmarking-sites.php",function(data){ for(var i = 0; i < data.length; i++){ //alert( data[i].id); bookmarkingSites += '<option value = \"' + data[i].id + '\">' + data[i].title + '</option>'; } }); <some more code> -------> toAppend += '<td><select name="sb2" id="sb2">'+ '<option value="'+ data.results[i].bookmark +'">' + data.results[i].bookmark +'</option>' + bookmarkingSites + '</select></td>'; <some more code>

  • Adding a loading gif to simple script

    - by bluedaniel
    Hello everyone, Im really really new to Javascript but Ive got this script that loads the contents of a url and everything works fine. I call the plannerSpin function with an onClick method on a button but how would I go about displaying an animated gif whilst all this is going on? var xmlHttp function plannerSpin(str) { xmlHttp = GetXmlHttpObject() if (xmlHttp == null) { alert("Browser does not support HTTP Request") return } var url = "/recipes/planner/data" xmlHttp.onreadystatechange = stateChanged xmlHttp.open("GET", url, true) xmlHttp.send(null) } function stateChanged() { if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete") { document.getElementById("recipe_planner_container").innerHTML = xmlHttp.responseText } } function GetXmlHttpObject() { var xmlHttp = null; try { // Firefox, Opera 8.0+, Safari xmlHttp = new XMLHttpRequest(); } catch (e) { // Internet Explorer try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; }

    - by Dejan.S
    Hi I'm using jTemplate for the first time. I been reading and it's not that hard to use it BUT what I can not figure out and find any thing on is how to work with one object, all the examples I find are a list of objects. My situation is I need to work with one object only. How can I do that? I mean How to work with the data in the jTemplate like this example but one only. <script type="text/html" id="TemplateResultsTable"> {#template MAIN} <table cellpadding="10" cellspacing="0"> <tr> <th>Artist</th> <th>Company</th> <th>Title</th> <th>Price</th> </tr> {#foreach $T.d as CD} {#include ROW root=$T.CD} {#/for} </table> {#/template MAIN} {#template ROW} <tr class="{#cycle values=['','evenRow']}"> <td>{$T.Artist}</td> <td>{$T.Company}</td> <td>{$T.Title}</td> <td>{$T.Price}</td> </tr> {#/template ROW} </script>

  • Empty POST from jQuery UI Dialog to PHP function with $.post

    - by solefald
    Hello, I am having hell of a time trying to figure this one out. Maybe someone can help me here or point me in the right direction. I have a jQuery UI dialog that pops up when user clicks on an image. The dialog displays a form with 2 drop down windows. "dept" and "group". Group drop down is disabled, until something is selected in the "dept" dropdown menu. When user selects a department, I do a POST to php function and then enable and populate the group drop down. Simple enough... <select name="dept" id="dept_select" onchange="getDeptGroups(this.value);"> // Some data here </select> JS function: function getDeptGroups(dept) { // This alert works and displays department name. //alert(dept); $.post("/am/ldap/getDepartmentGroups.php", { department: dept }, function(data){ alert(data); }); } and finally in php page i just do <? print_r($_POST); ?> and end up with empty array. Array ( ) This happens in both, Chrome and Firefox, however, FireBug clearly shows post data being submitted: What am i doing wrong here?

  • jQuery / jqGrids / Submitting form data troubles...

    - by Kelso
    Ive been messing with jqgrids alot of the last couple days, and I have nearly everything the way I want it from the display, tabs with different grids, etc. Im wanting to make use of Modal for adding and editing elements on my grid. My problem that Im running into is this. I have my editurl:"editsu.php" set, if that file is renamed, on edit, i get a 404 in the modal.. great! However, with that file in place, nothing at all seems to happen. I even put a die("testing"); line at the top, so it sees the file, it just doesnt do anything with it. Below is the content. ........ the index page jQuery("#landings").jqGrid({ url:'server.php?tid=1', datatype: "json", colNames:['ID','Tower','Sector', 'Client', 'VLAN','IP','DLink','ULink','Service','Lines','Freq','Radio','Serial','Mac'], colModel:[ {name:'id', index:'id', width : 50, align: 'center', sortable:true,editable:true,editoptions:{size:10}}, {name:'tower', index:'tower', width : 85, align: 'center', sortable:true,editable:false,editoptions:{readonly:true,size:30}}, {name:'sector', index:'sector', width : 50, align: 'center',sortable:true,editable:true,editoptions:{readonly:true,size:20}}, {name:'customer',index:'customer', width : 175, align: 'left', editable:true,editoptions:{readonly:true,size:35}}, {name:'vlan', index:'vlan', width : 35, align: 'left',editable:true,editoptions:{size:10}}, {name:'suip', index:'suip', width : 65, align: 'left',editable:true,editoptions:{size:20}}, {name:'datadl',index:'datadl', width:55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'dataul', index:'dataul', width : 55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'servicetype', index:'servicetype', width : 85, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from servicetype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'voicelines', index:'voicelines', width : 35, align: 'center',editable:true,editoptions:{size:30}}, {name:'freqname', index:'freqname', width : 35, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from freqband"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'radioname', index:'radioname', width : 120, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from radiotype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'serial', index:'serial', width : 100, align: 'right',editable:true,editoptions:{size:20}}, {name:'mac', index:'mac', width : 120, align: 'right',editable:true,editoptions:{size:20}} ], rowNum:20, rowList:[30,50,70], pager: '#pagerl', sortname: 'sid', mtype: "GET", viewrecords: true, sortorder: "asc", altRows: true, caption:"Landings", editurl:"editsu.php", height:420 }); jQuery("#landings").jqGrid('navGrid','#pagerl',{edit:true,add:true,del:false,search:false},{height:400,reloadAfterSubmit:false},{height:400,reloadAfterSubmit:false},{reloadAfterSubmit:false},{}); now for the editsu.php file.. $operation = $_REQUEST['oper']; if ($operation == "edit") { qquery("UPDATE customers SET vlan = '".$_POST['vlan']."', datadl = '".$_POST['datadl']."', dataul = '".$_POST['dataul']."', servicetype = '".$_POST['servicetype']."', voicelines = '".$_POST['voicelines']."', freqname = '".$_POST['freqname']."', radioname = '".$_POST['radioname']."', serial = '".$_POST['serial']."', mac = '".$_POST['mac']."' WHERE id = '".$_POST['id']."'") or die(mysql_error()); } Im just having a hard time troubleshooting this to figure out where its getting hung up at. My next question after this would be to see if its possible to make it so when you click "add", that it auto inserts a row into the db with a couple variable predtermined and then bring up the modal window, but ill work on the first problem first. thanks!

  • High-Performance In-Browser Networking

    - by Jon Purdy
    (Similar in spirit to but different in practice from this question.) Is there any cross-browser-compatible, in-browser technology that allows a high-performance perstistent network connection between a server application and a client written in, say, Javascript? Think XmlHttpRequest on caffeine. I am working on a visualisation system that's restricted to at most a few users at once, and the server is pretty robust, so it can handle as much as it needs to. I would like to allow the client to have access to video streamed from the server at a minimum of about 20 frames per second, regardless of what their graphics hardware capabilities are. Simply put: is this doable without resorting to Flash or Java?

  • Sys undefined for HTTPS url in IE8

    - by Dhana
    I just discovered a rather peculiar issue in IE8 for a HTTPS link. Every time the page tries to access the HTTPS link, it produces an error. This happens only in IE8 and nothing else. Any idea what's going on? I found some items that said that means the files were not loaded, hence the issue and tried some fixes recommended, but they haven't worked so far. This is a .NET site by the way. https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 70 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 319 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx

    Hi all, I try to implement a vote feature in one of my rails projects. I use the following codes (in vote.rjs) to replace the page with a Partial template (_vote.rhtml). But when I click, the vote number can not be updated immediately. I have to refresh the page to see the change. vote.rjs page.replace("votes#{@foundphoto.id}", :partial="vote", :locals={:voteable=@foundphoto}) The partial template is as follows: _vote.rhtml " <%= link_to_remote "+(#{voteable.votes_for})", :update="vote", :url = { :action="vote", :id=voteable.id, :vote="for"} % / <%= link_to_remote "-(#{voteable.votes_against})", :update="vote", :url = { :action="vote", :id=voteable.id, :vote="against"} % any ideas? Thanks.

  • if cookies are disabled, does asp.net store the cookie as a session cookie instead or not?

    - by Erx_VB.NExT.Coder
    basically, if cookeis are disabled on the client, im wondering if this... dim newCookie = New HttpCookie("cookieName", "cookieValue") newCookie.Expires = DateTime.Now.AddDays(1) response.cookies.add(newCookie) notice i set a date, so it should be stored on disk, if cookies are disabled does asp.net automatically store this cookie as a session cookie (which is a cookie that lasts in browser memory until the user closes the browser, if i am not mistaken).... OR does asp.net not add the cookie at all (anywhere) in which case i would have to re-add the cookie to the collection without the date (which stores as a session cookie)... of course, this would require me doing the addition of a cookie twice... perhaps the second time unnecessarily if it is being stored in browsers memory anyway... im just trying not to store it twice as it's just bad code!! any ideas if i need to write another line or not? (which would be)... response.cookies.add(New HttpCookie("cookieName", "cookieValue") ' session cookie in client browser memory thanks guys

  • My ASP.NET Accordion will not animate panel changes when triggered by check boxes.

When I click the checkbox to change the panel, the panel just disappears instantly and the new one appears instantly, but I want it to be animated as if I clicked the headers. Is there a way to cause the animation to happen when force changing the visible panel?

  • Reading xml document in firefox

  • Switching from Sourcesafe - What to look for in a product

    - by asp316
    We're looking to move off of sourcesafe and on to a more robust source control system for our .Net apps. We're also looking for scripted/automated deployments. I'm a .Net developer (web and winforms). However, most of our development staff is RPG for the IBM iSeries and the devs use Aldon's LMI for source control and deployment. Our manager would prefer to stick with Aldon so all of our products are in the same system. However, I don't have experience with Aldon's products on the .Net side. I've used TFS and Subversion with Tortoise a bit, but not enough to recommend one or the other, especially in comparison to Aldon's product. Does anybody have experience with Aldon's products? If so, thoughts please? Also, other than the obvious things source control systems do, are there things I should avoid or are there must haves? I'm open to any system. A bit of background, I'm the only .Net dev in our company but I let operations do the deployments. I do want the ability to support concurrent checkouts if we hire a new dev.

  • Full page reload on Post/Redirect/Get ignoring cache control

    - by Kristof Neirynck
    I have a page that loads a lot of images, css and javascript. I've added a far future Expires header and set Cache-Control to public on these external dependencies so they should be cached. But every time I do a Post/Redirect/Get chrome tries to load these again. This behavior is very similar to reloading the page. I've added ETags and handle the If-None-Match header which helps a bit, but it still generates too many useless requests. How do I tell chrome and safari to get the files from cache? chrome NOK safari NOK firefox OK ie OK Also see Full page reload on Post/Redirect/Get ignoring cache control on the google support forum.

  • High density Silverlight charting control

    - by ahosie
    I've been looking into Silverlight charting controls to display a large number of samples, (~10,000 data points in five separate series - ~50k points all up). I have found the existing options produced by Dundas, Visifire, Microsoft etc to be extremely poor performers when displaying more than a few hundred data points. I believe the performance issues with existing chart controls is caused by the heavy use of vector graphics. Ergo one solution would be a client-side chart control that uses the WritableBitmap class to generate a raster chart. Before I fall too far down the wheel re-invention rabbit hole - has anyone found a third party or OSS control that will manage large numbers of data points on a sparkline?

  • JQuery Passing Variable From href to load()

My simple example that is obviously not working. I want to refresh the db select part of the page showing the new list of cars.

EX: var userId = MyuserID; var perPage = '45'; var showOnPage = '45'; var tag = 'tag1'; var tag1 = 'tag2'; var tag2 = 'tagn'; $.getJSON('http://api.flickr.com/services/rest/?format=json&method='+ 'flickr.photos.search&api_key=' + apiKey + '&user_id=' + userId + '&tags=' + tag + '&per_page=' + perPage + '&jsoncallback=?', function(data){ var classShown = 'class="lightbox"'; var classHidden = 'class="lightbox hidden"'; $.each(data.photos.photo, function(i, rPhoto){ var basePhotoURL = 'http://farm' + rPhoto.farm + '.static.flickr.com/' + rPhoto.server + '/' + rPhoto.id + '_' + rPhoto.secret; var thumbPhotoURL = basePhotoURL + '_s.jpg'; var mediumPhotoURL = basePhotoURL + '.jpg'; var photoStringStart = '<li><a '; var photoStringEnd = 'title="' + rPhoto.title + '" href="'+ mediumPhotoURL +'"><img src="' + thumbPhotoURL + '" alt="' + rPhoto.title + '"/></a><span>'+rPhoto.title+'</span></li>;' var photoString = (i < showOnPage) ? photoStringStart + classShown + photoStringEnd : photoStringStart + classHidden + photoStringEnd; $(photoString).appendTo("#flickr ul"); }); $("#flickr a").fancybox(); }); $.getJSON('http://api.flickr.com/services/rest/?format=json&method='+ 'flickr.photos.search&api_key=' + apiKey + '&user_id=' + userId + '&tags=' + tag1 + '&per_page=' + perPage + '&jsoncallback=?', function(data){ var classShown = 'class="lightbox"'; var classHidden = 'class="lightbox hidden"'; $.each(data.photos.photo, function(i, rPhoto){ var basePhotoURL = 'http://farm' + rPhoto.farm + '.static.flickr.com/' + rPhoto.server + '/' + rPhoto.id + '_' + rPhoto.secret; var thumbPhotoURL = basePhotoURL + '_s.jpg'; var mediumPhotoURL = basePhotoURL + '.jpg'; var photoStringStart = '<li><a '; var photoStringEnd = 'title="' + rPhoto.title + '" href="'+ mediumPhotoURL +'"><img src="' + thumbPhotoURL + '" alt="' + rPhoto.title + '"/></a><span>'+rPhoto.title+'</span></li>;' var photoString = (i < showOnPage) ? photoStringStart + classShown + photoStringEnd : photoStringStart + classHidden + photoStringEnd; $(photoString).appendTo(".SetPinos1 ul"); }); $(".Sets a").fancybox(); }); $.getJSON('http://api.flickr.com/services/rest/?format=json&method='+ 'flickr.photos.search&api_key=' + apiKey + '&user_id=' + userId + '&tags=' + tagn + '&per_page=' + perPage + '&jsoncallback=?', function(data){ var classShown = 'class="lightbox"'; var classHidden = 'class="lightbox hidden"'; $.each(data.photos.photo, function(i, rPhoto){ var basePhotoURL = 'http://farm' + rPhoto.farm + '.static.flickr.com/' + rPhoto.server + '/' + rPhoto.id + '_' + rPhoto.secret; var thumbPhotoURL = basePhotoURL + '_s.jpg'; var mediumPhotoURL = basePhotoURL + '.jpg'; var photoStringStart = '<li><a '; var photoStringEnd = 'title="' + rPhoto.title + '" href="'+ mediumPhotoURL +'"><img src="' + thumbPhotoURL + '" alt="' + rPhoto.title + '"/></a><span>'+rPhoto.title+'</span></li>;' var photoString = (i < showOnPage) ? photoStringStart + classShown + photoStringEnd : photoStringStart + classHidden + photoStringEnd; $(photoString).appendTo(".SetPinos ul"); }); $(".Sets a").fancybox(); }); var tag is only one difference in this url : Can somebody help me not to repeat all this stuff ??
