• Tag-like autocompletion and caret/cursor movement in contenteditable elements.

  - by jimeh

  I'm working on a jQuery plugin that will allow you to do @username style tags, like Facebook does in their status update input box. My problem is, that even after hours of researching and experimenting, it seems REALLY hard to simply move the caret. I've managed to inject the <a> tag with someone's name, but placing the caret after it seems like rocket science, specially if it's supposed work in all browsers. And I haven't even looked into replacing the typed @username text with the tag yet, rather than just injecting it as I'm doing right now... lol There's a ton of questions about working with contenteditable here on Stack Overflow, and I think I've read all of them, but they don't really cover properly what I need. So any more information anyone can provide would be great :)

• Loop through JSON data Associatively

  - by Abs

  Hello all, How can I loop through this json data without referring to the data items by a number. I would like to use it as an associative array. I have this so far: $.post('/controlpanel/search', { type: type, string: string }, function(data){ $.each(data, function() { $.each(this, function(index, itemData) { //alert(data.id) something like this //currently returns undefined }); }); }, 'json'); Example Json Code: [{"id":"1","title":"","link":"http:\/\/www.msn.com","date_added":"0000-00-00 00:00:00", "privacy_type":"0","user_id":"8","field2":"","field3":"","bookmark_id":"70","tag":"clean"}] Thanks all for any help

• JSLINT error: Move all 'var' declarations to the top of the function.

  - by Oleg Yaroshevych

  JSLINT site updated, and I cannot check JS scripts anymore. For me, this warning is not critical, and I don't want to go through thousands of lines to fix this, I want to find more critical problems. Does anybody know how to turn off this error, or use legacy JSLINT? UPDATE Example: function doSomethingWithNodes(nodes){ this.doSomething(); for (var i = 0; i < nodes.length; ++i){ this.doSomethingElse(nodes[i]); } doSomething(); // want to find this problem } jslint.com output: Error: Problem at line 4 character 8: Move all 'var' declarations to the top of the function. for (var i = 0; i < nodes.length; ++i){ Problem at line 4 character 8: Stopping, unable to continue. (44% scanned). Problem: Having variables on top of the functions is new requirement. I cannot use JSLINT to test code, because it stops scanning script on this error. I have a lot of code, and do not want to threat this warning as critical error.

• In Node.JS, how do I return an entire object from a separate .js file?

  - by Matthew Patrick Cashatt

  Thanks for looking. I am new to Node.js and trying to figure out how to request an object from a separate file (rather than just requesting a function) but everything I try--exports,module-exports,etc--is failing. So, for example, if I have foo.js: var methods = { Foobar:{ getFoo: function(){return "foo!!";}, getBar: function(){return "bar!!";} } }; And now I want to call a function within an object of foo.js from index.js: var m = require('./Methods'); function fooMain(){ return m.Foobar.getFoo(); }; How do I do this? I have tried all sorts of combinations of exports and module-exports but they seem to only work if I call a discrete function that is not part of an object. Thanks!

• this.optional() in jQuery validation method doesn't seem to work

  - by HiveHicks

  Hello, I've got a little problem here. I've got the following rule for one of my fields: StartDate: { required: isDelayed, dateRU: true } isDelayed() returns false, so I guess StartDate field should be optional. However if I check it inside my dateRU method: $.validator.addMethod( "dateRU", function(value, element) { return this.optional(element) || isValidDate($.trim(value)); }, "Date is incorrect" ); this.optional(element) always returns false for StartDate. I can't figure out what's wrong. Any ideas? UPD. Does optional() returns true only if element is not required AND IS EMPTY? 'Cause that may be my problem.

• jQuery click event on parent, but finding the child (clicked) element

  - by Mahdi

  let say I have a parent element which has so many nested child elements inside of itself: <div id="p"> <div id="c1"> <div id="c2"></div> <div id="c3"></div> </div id="c4"> <div id="c5"></div> </div> </div> I've already bind a click event on the parent: $('#p').bind('click', function() { alert($(this).attr('id')); }); Because the event is assigned to the parent element, I always see the parent id, however, I'm wondering if there is any possible way to find out which of this child elements has been clicked? I also can't assign any event to the child elements or remove the event listener from parent div.

• Horizontally-centering an absolute position to match a relative position

  - by Chris Vandevelde

  I'm trying to make a div box, containing various elements, fixed at the top of the page once the page has been scrolled so that the box would normally be out of view, but scroll normally until that point (like the behaviour at http://perldoc.perl.org/perl.html). The conditionally-fixed part is pretty simple to implement (set the position to "fixed" once the user has scrolled past a certain point, and "static" once it's scrolled back up), but I'm having trouble with the positioning and dimensions; it screws up if I'm not specifying an absolute position (if I'm using % or "auto", rather than px, em, cm, etc.) or it, confusingly, left-aligns if the box is less than the width of the page. I can understand why, more or less, I'm just trying to fix it. My strategy right now is to have an invisible DIV hold the place of the box and use Prototype's clonePosition() function to hold its position, but it doesn't seem to work for some reason. Neither does copying the margin from one element to the other. Any ideas? Bonus points and eternal gratitude if you can come up with an idea that will adjust itself with the browser window (like auto margins) without setting an onresize event.

• Possible to capture all events in a web browser?

  - by David

  I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.

• merging two small pieces of jquery codes

  - by Billa

  Following are two pieces of jquery code. First one prints a text message when clicked on a link, and the second slides down a div when click on a link. I want to merge second code into first one, so that when I click the link, it displays the message (as the first code does), and also slides down the #votebox (as done in second code, and show content in that. I will be very thankful for any help. $("a.vote_up").click(function(){ the_id = $(this).attr('id'); $("span#votes_count"+the_id).fadeOut("fast"); $.ajax({ type: "POST", data: "action=vote_up&id="+$(this).attr("id"), url: "votes.php", success: function(msg) { $("span#votes_up"+the_id).fadeOut(); $("span#votes_up"+the_id).html(msg); $("span#votes_up"+the_id).fadeIn(); //Here, I want to slide down the votebox and content div (from code below). } }); }); The following code slides down votebox div and displays content in it, I want to include that in the above code. $("a.vote_up").click(function(){ var id=$(this).attr("id"); var name=$(this).attr("name"); var dataString = 'id='+ id + '&name='+ name; //I want to include this votebox in above code. $("#votebox").slideDown("slow"); $("#flash").fadeIn("slow"); $.ajax({ type: "POST", url: "rating.php", data: dataString, cache: false, success: function(html){ $("#flash").fadeOut("slow"); //and want to use this div as well. $("#content").html(html); } }); }); Thanks for any help.

• Jquery Basic Beginner Question: How do i make my function reusable?

  - by obikodi

  I have spent the last few hours attempting to do this on my own, and using Google to find a solution but to no avail. So if you can help out i would super appreciate it! Basically I have a page which has 3 separate biographies in 'preview mode', which shows only the first paragraph of each bio. When you click on 'read more' for one bio it opens up the 'full mode'. What is happening at the moment, is if i click on one 'read more' link, it opens up the full mode on all 3 bio's. How do i edit the following code so; It only opens the full mode bio of the link i click on Make it reusable so i don't have to duplicate the code 3 times for each bio $("a#btnReadMore").click(function(){ $('.readMoreSlider').slideToggle("fast"); $(this).toggleClass("readMoreSliderActive"); return false; }); Thanks for your help!

• jQuery: Moving window (or FIFO) type DIV?

  - by Legend

  I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

• Iterating through list of keys for associative array in JSON

  - by Simon_Weaver

  I have an associative array in JSON var dictionary = {"cats":[1,2,37,38,40,32,33,35,39,36], "dogs", [4,5,6,3,2]}; Can I get the keys from this? I tried in Visual studio putting a breakpoint but can't see any property that represents keys. Is it not possible? I'm fine creating a separate array if necessary, but was just hoping it wasnt : var keys = ["cats", "dogs"];

• Inconsistent table width when hideing/showing a set of columns

  - by Salman A. Kagzi

  I have got a an HTML table of around 40+ columns. To make this table fit in the screen and have the data in a re presentable format we have section in this table. i.e. there are some column that are always visible and the remainder a made visible when s specific radio button (describing a section) is selected. Each radio button is associated to different number of columns. We show/hide a column by setting/removing "display:none" style in all the cell under that column. This all works Just fine. Now the real problem is with the width of the columns in this table. I cant use fixed with with pixel settings. I have tried using the percentage setting by giving 50% to the always visible part and rest 50% is divided between the column in a section. But I am unable to get a fixed behavior i.e. the size of the table columns across IE & FF. Some columns are just right while some are really huge. How can I get the table to give consistent column width across browsers?

• JQuery How to Uncheck A radio button

  - by user281867

  Hi, I have a list of data with a radio button. Users must select a date to edit. Then I load external dynamic form into a [div] using the jquery load() function. var ID = $('input[name=BookItem]:checked').val(); $("#EditFormWrapper").load("callEditData.cfm? ID="+ID); 2 Hours AM 2 Hours PM 2 Hours AM 2 Hours PM I am having trouble uncheck the radio button when user click on cancel button (editBTNcancel). The “BookItem” radio button is on the already on the webpage before the load() call. Here s my script: $("#editBTNcancel").live("click", function(event){ event.preventDefault(); $("#EditFormWrapper").slideUp("fast").empty(); //$('.TOR2Hours').removeAttr('checked'); $('.TOR2Hours').attr('checked', false); }); I hope I clearly state my problem, any suggestion would be greatly appreciated!

• I need help understanding how this jQuery filter function works, line-by-line, if possible

  - by user717236

  Here is the HTML: <div> <h3>text</h3> </div> <div> <h3>moretext</h3> </div> <div> <h3>123</h3> </div>?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Here is the JS: var rv1_wlength = $("div").filter(function() { return $(this).find("h3").filter(function () { return $(this).text() != "123"; }).length; }); var rv1_wolength = $("div").filter(function() { return $(this).find("h3").filter(function () { return $(this).text() != "123"; }); }); var rv2 = $("div").find("h3").filter(function() { return $(this).text() != "123"; }); alert(rv1_wlength.text()); // text // moretext alert(rv1_wolength.text()); // text // moretext // 123 alert(rv2.text());? // textmoretext I don't understand why the first two methods print the elements on each line, whereas the second method concatenates them. "rv2" is a jQuery object. Then, what are the first two (rv1_wlength and rv1_wolength)? Furthermore, I don't understand why the inclusion of the length property makes all the difference in filtering the elements. The second method does nothing, since it returns all the elements. The first method, with the only change being the addition of the length property, correctly filters the elements. I would very much like a line-by-line explanation. I would sincerely appreciate any feedback. Thank you.

• dynamic model is not loading fields

  - by Toby Justus

  I am using a dynamic model found on the forum of sencha. function modelFactory(name, fields) { alert(fields); return Ext.define(name, { extend: 'Ext.data.Model', fields: fields }); } I placed the alert(fields) to check what happens with the field because it was not working. I get this: [object Object],[object Object],[object Object] How can i change this into a correct way to use it in the fields? Is there a way to check if the model has been created? With Firebug or something? EDIT: i get this in firebug: [Object { name="ccuDesignation", type=null}, Object { name="wanNumber", type=null}, Object { name="carrierName", type=null}, Object { name="dataPackageName", type=null}, Object { name="simIccid", type=null}, Object { name="expiryTime", type=null}, Object { name="bytesRx", type=null}, Object { name="bytesTx", type=null}]

• adding new Input to jquery validationEngine form?

  - by Hailwood

  I have some fairly complex ajax logic etc going on in the onValidationComplete function for a form with jQuery Validation Engine. This is working perfect, but one thing is bothering me. in the form I have the ability to dynamically add inputs (add new row button). so my code structure wise looks like: var form = $('#myForm'); form.validationEngine('attach', {onValidationComplete:validationComplete}); $('#newInput').on('click', function(){ form.append('<input />'); form.validationEngine('detach'); form.validationEngine('attach', {onValidationComplete:validationComplete}); }); function validationComplete(form, status){/*all my logic here*/} What I don't like about it is that every time I add a new input I have to detach and then re-attach the validationEngine. Is there any way to just tell it to add the new input to it's list of inputs to validate?

• How to use Spanish characters in Handlebars templates

  - by Jon Rose

  I am wondering what the idiomatic way to render special language characters is using Handlebars.js templates. When I render the normal html I can use something like the Spanish lowercase e, &#233, and it renders as expected. When I pass the same text as a string to my Handlebars template I just see the characters &#233. I have tried creating a Handlebars helper that used jquery to render the text using .html() then returning the .html() of the tmp element and I get the same results.

• How can I make a Twitter style alert stick to the top of the window?

  - by Robert Robb

  There is an excellent code example on how to make nice jQuery Twitter style alerts here: http://blog.codecrate.com/2009/10/twitter-style-alerts-in-rails.html $(function () { var alert = $('.alert'); if (alert.length > 0) { alert.show().animate({height: alert.outerHeight()}, 200); window.setTimeout(function() { alert.slideUp(); }, 3000); } }); However, one thing that the code doesn't include is functions to stick the alert div to the top of the window, no matter how far down the page the user has scrolled. I have found a few examples but nothing seems to play nice with this existing code. Any ideas?

• Replacing Text Nodes With DOM Nodes

  - by Greg

  Hey, say I have a text node via XPath. How would I replace the text node with a new DOM node? For example, this little patch of code will go through text nodes, and if text matches something, it will replace it with a corresponding image via img element. I wanted something faster then a global page regex or even a element innerHTML regex. Any help would be appreciated. EDIT: Never mind. I figured it out.
