  • How to debug node.js applications

    - by Fabian Jakobs
    How do I debug a node.js server application? Right now I'm mostly using alert debugging with print statements like this: sys.puts(sys.inspect(someVariable)); There must be a better way to debug. I know that google Chrome has a command line debugger. Is this debugger available for node.js as well?

  • jQuery: shorten string length to fit a set width.

    - by Marius
    Hello there, I have a table, and in each cell I want to place strings, but they are much wider than the cell width. To prevent line break, I would like to shorten the strings to fit the cell, and append '...' at end to indicate that the string is much longer. The table has about 40 rows and has to be done to each cell, so its important that its a quick. Should I use JS/jQuery for this? How would I do it? Thank you for your time. Kind regards, Marius

  • Checkbox not being checked when running function

    - by Rudiger
    I have a checkbox that when it is clicked it submits the form to the server to store the detail. All works fine except that after the form is submitted I update a div to say submitted but the checkbox isn't ticked. The page isn't refreshed of course and upon page refresh it is ticked. I thought I might be able to check the box myself as I'm using jQuery but I have a lot of these checkboxes each with a dynamic name so I'm not sure how I would call them. I thought something like: $('input[name=("favourite" + id)]').attr('checked', true); might work but no luck. If I don't call the function on the checkbox being ticked the checkbox behaves normally. Thanks for anything that could help.

  • Can I prevent window.onbeforeunload from being called when doing an AJAX call

    - by Paul
    I have an AJAX-based grid control. We hook into the window.onbeforeunload event to check if they have unsaved data and if so present them with a message "Are you sure you want to navigate away...you have unsaved data...". All this is good. But AJAX calls also trigger window.onbeforeunload and so if the grid has unsaved data and we make an AJAX call (such as to delete a row in another grid) the user gets the "Are you sure you want to navigate away...you have unsaved data..." message which is not good. Is it possible to suppress the onbeforeunload event for AJAX calls? Or is it possible to detect that a call is an AJAX call? Otherwise we'll have to get hacking! Thanks

  • WebKit "Refused to set unsafe header "content-length"

    - by Paul
    I am trying to implement simple xhr abstraction, and am getting this warning when trying to set the headers for a POST. I think it might have something to do with setting the headers in a separate js file, because when i set them in the <script> tag in the .html file, it worked fine. The POST request is working fine, but I get this warning, and am curious why. I get this warning for both content-length and connection headers, but only in WebKit browsers (Chrome 5 beta and Safari 4). In Firefox, I don't get any warnings, the Content-Length header is set to the correct value, but the Connection is set to keep-alive instead of close, which makes me think that it is also ignoring my setRequestHeader calls and generating it's own. I have not tried this code in IE. Here is the markup & code: test.html: <!DOCTYPE html> <html> <head> <script src="jsfile.js"></script> <script> var request = new Xhr('POST', 'script.php', true, 'data=somedata', function(data) { console.log(data.text); }); </script> </head> <body> </body> </html> jsfile.js: function Xhr(method, url, async, data, callback) { var x; if(window.XMLHttpRequest) { x = new XMLHttpRequest(); x.open(method, url, async); x.onreadystatechange = function() { if(x.readyState === 4) { if(x.status === 200) { var data = { text: x.responseText, xml: x.responseXML }; callback.call(this, data); } } } if(method.toLowerCase() === "post") { x.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); x.setRequestHeader("Content-Length", data.length); x.setRequestHeader("Connection", "close"); } x.send(data); } else { // ... implement IE code here ... } return x; }

    Is there any way to completely disable web page scrolling in an iPhone web app? I've tried numerous things posted on google, but none seem to work.

  • Extjs: Tree, Selecting node after creating the tree

    - by Natkeeran
    I have a simple TreePanel. I would like to select a particular node upon loading it. The nodes are from a remote file (json). The tree is loading as expected. However, the node is not being selected. Firebug shows node as undefined. This perhaps because of the async property. But, I an unable to configure this other wise, or specify the node be selected. Any suggestions welcomed, and thank you. LeftMenuTree = new Ext.tree.TreePanel({ renderTo: 'TreeMenu', collapsible: false, height: 450, border: false, userArrows: true, animate: true, autoScroll: true, id: 'testtest', dataUrl: fileName, root: { nodeType: 'async', iconCls:'home-icon', expanded:true, text: rootText }, listeners: { "click": { fn: onPoseClick, scope: this } }, "afterrender": { fn: setNode, scope: this } }); function setNode(){ alert (SelectedNode); if (SelectedNode == "Orders"){ var treepanel = Ext.getCmp('testtest'); var node = treepanel.getNodeById("PendingItems"); node.select(); } }

  • Is fckeditor free for use in freelance projects?

    - by Ali
    This is more of a licencing issue than a code question. I really like the ckeditor editor and would like to use it in my freelance projects which I do for clients. However upon reading the license page it has me in a bit of a confusion. DO I have to buy licences if I intend to use this in cms websites that I build myself and hand over to clients? If so then what are my alternate options which don't cost anything?

  • user disallowed geolocation - notify user second time

    - by Dror
    When trying to get geolocation on iPhone the first time - I declined. Every other time I want to get the location (before another reload of the page) I get no response (no error and no success): navigator.geolocation.getCurrentPosition( function (location) { ig_location.lat = location.coords.latitude; ig_location.lng = location.coords.longitude; alert('got it!'); }, function(PositionError) { alert('failed!' + PositionError.message); } ); Is there a way to notify the user every time I fail to get the location? (I do not need to use watchPosition...)

  • jquery Autocomplete : autocomplete does not stop if string does not match

    - by Daniyal
    I used the auto-complete function in jquery. It's data source are the results from a php-back-end. $("#ice_id").autocomplete("ice-ver.php", { extraParams : { flavour_id: $("#flavour_id").val() } }); Let us take following example: We type in the flavour ID 3992 ...(and 3992 exists in the database and is properly returned by the php backend). If we type in now 3992999 the auto-complete function should top showing anything up ...but unfortunately it still does, (could the problem lie within the fact that I am using integers instead of strings or chars?) Thanks in advance for any hints and best regards Daniyal

  • I can't get onChange to fire for dijit.form.Select

    - by user306462
    I seem unable to correctly attach the onchange event to a dijit.form.Select widget. However, I am new to web development, so I could be doing something completely idiotic (although, as best I can tell (and I've read all the docs I could find) I'm not). I made sure the body class matches the dojo theme, that I dojo.require() for all the widgets I use (and dojo.parser), and still, nada. The code I'm using is: dojo.addOnLoad (function () { var _query = dojo.query('.toggle'); for (var i=0; i < _query.length; i++) { dojo.connect(_query[i], 'onchange', function (ev) { console.log(ev + ' fired onchange'); }); } }); Any help at all would be appreciated.

  • Niceforms and jQuery events

    - by Michael Edwards
    Our design agency has supplied HTML that uses NiceForms. The problem I am having is that this mucks up jQuery event binding. I have the following code: keys = $("#key input"); $(keys).each(function(){ $(this).change(function() { console.log("hi"); } } If I disable NiceForms this code works but with Niceforms enabled it doesn't. How do I get around this problem?

  • Best way to escape characters before jquery post ASP.NET MVC

    - by Darcy
    Hello, I am semi-new to ASP.NET MVC. I am building an app that is used internally for my company. The scenario is this: There are two Html.Listbox's. One has all database information, and the other is initally empty. The user would add items from the database listbox to the empty listbox. Every time the user adds a command, I call a js function that calls an ActionResult "AddCommand" in my EditController. In the controller, the selected items that are added are saved to another database table. Here is the code (this gets called every time an item is added): function Add(listbox) { ... //skipping initializing code for berevity var url = "/Edit/AddCommand/" + cmd; $.post(url); } So the problem occurs when the 'cmd' is an item that has a '/', ':', '%', '?', etc (some kind of special character) So what I'm wondering is, what's the best way to escape these characters? Right now I'm checking the database's listbox item's text, and rebuilding the string, then in the Controller, I'm taking that built string and turning it back into its original state. So for example, if the item they are adding is 'Cats/Dogs', I am posting 'Cats[SLASH]Dogs' to the controller, and in the controller changing it back to 'Cats/Dogs'. Obviously this is a horrible hack, so I must be missing something. Any help would be greatly appreciated.

  • What is the best alternative for jQuery thickbox

    - by Teja Kantamneni
    As jQuery thickbox is not maintained anymore (as of ThickBox 3.1), what is the best alternative for jQuery thickbox currently available under GPL or similar license. Looks nyromodal is best available so far, but is there anything better. (nyromodal has some problems in IE 6) I am looking for a plugin which can handle ajax forms, inline content replacement, images, using hidden elements and ajax call with flexibility using the callback mechanisms..

  • JSON.parse string with quotes

    - by mjsilva
    Hi, I've this: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\" SATA2 7200rpm"}}'); http://www.jsonlint.com/ says it's perfectly valid json. But on execution I have a JSON.parse error. But, if I change my code to: JSON.parse('{"130.00000001":{"p_cod":"130.00000001","value":"130.00000001 HDD Upgrade to 2x 250GB HDD 2.5\\" SATA2 7200rpm"}}'); (note the double backslash) It works, but now jsonlint gives me invalid json :/ Can someone help to understand this behavior?

  • Setting the value (selected option) of a dijit.form.Select widget

    - by Wahnfrieden
    I have a dijit.form.Select widget. It's tied to a data store, if that matters. It's filled with several options already. All I want to do is programmatically set its value. I can get its value using myWidget.attr('value') but if I try to do myWidget.attr('value', 5) for example (where 5 is one of the valid values), all it does is reset the widget to select the very first option, no matter what value I give it. This seems to be a bug, and there aren't any tests or documentation which show how to accomplish what I want to. But is there some way, even if it's a dirty hack? I'm using Dojo 1.4.0. Note that dijit.form.Select is the new name for dojox.form.DropDownSelect. edit: I even tried resetting the widget with all new options, but it ignores the option which has selected = true and just selects the first option. There must still be a way though.
