  • How do I nested options for plugins in jQuery

    - by Oscar Godson
    I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • Defining functions and if statement problems

    - by David Fairbairn
    I'm having a problem with two functions and an if statement. I'm being told the functions go and postcodeChange are not defined. I'm also being told flag is an unexpected identifier at if flag == 1. Any idea where I am going wrong? Thank you. function postcodeChange(){ document.getElementById("goButton").onclick = distanceCheck; } function distanceCheck(){ var distance = document.getElementById("distance").value var patt1=new RegExp("^[0-9]+(\.[0-9]{1})?$"); var out = patt1.exec(distance); if (out == null) { //distance is not a valid number document.getElementById("distanceFlag").value = 1 } else { //distance is valid number document.getElementById("distanceFlag").value = 0 } function go(){ var flag = document.getElementById("distanceFlag").value if flag == 1 { alert("Distance is not valid- enter a number with no more than one decimal point"); } else{ popSubmit('#fa Care Provider Search Go','','0'); } }

  • EasyXDM passing data issue

    - by Jeff Ryan
    I'm using rpc with XDM, and I can send simple data back and forth easily between child and parent window. But it seems to be limited to simple strings and numbers. The demos on the site only use numbers. When I try to send a json ecoded string, I get a cross domain error. When I use cors, I can make ajax requests fine, but I can't display the child page in the iframe, because the data is returned and not rendered. My question is, how can I render an iframe, and pass complex data back and forth. Or maybe I am doing something wrong?

  • Destructuring assignment in generator expressions and array comprehensions

    - by Eli Grey
    Why does for ([] in object); work fine but [void 0 for ([] in object)] or (void 0 for ([] in object)) throw a syntax error for invalid left-hand assignment? For example, I would expect the following code to work, but it doesn't (the assertion isn't even done due to the syntax error): let ( i = 0, arr = [1, 2, 3, 4], gen = (i for (i in arr) if (arr.hasOwnProperty(i)) ) { for ([] in gen) i++; console.assertEquals([void 0 for ([] in gen)].length, i); }

  • Create an autocompleter like the Facebook status update

    - by Terw
    Hello I'm trying to create a div with contenteditable like the Facebook status update. Then I mean I want to show an autocomplete box when the user have written @. How would you do that. Currently I'm just playing with keypress and check if the keycode = 64. Somehow that works, but it doesn't validate if there's a space before the alfa, or if the user has unfocused the box, then focused it again. Any ideas? Or do you know about any plugin that works something like that? Tnx

    - by amit
    i am trying to make the preloading work in such a way that the components i wish to preload start to load after successfully loading the page. for example, i have index.php. i want it to load up completely. as soon as it loads up i want to start loading the other components. to make things clear. i have a nav that makes use of large size images. if i load them along with the index.php file, it would increase load up time of the page. i wish for those large images to load after completely rendering index.php? am i making sense? is it possible?

  • Using the Module Pattern for larger projects

    - by Rob
    I'm interested in using the Module Pattern to better organize my future projects. Unfortunately, there are only a few brief tutorials and proof-of-concept examples of the Module Pattern. Using the module pattern, I would like to organize projects into this sort of structure: project.arm.object.method(); Where "project" is my global project name, "arm" is a sub-section or branch of the project, "object" is an individual object, and so on to the methods and properties. However, I'm not sure how I should be declaring and organizing multiple "arms" and "objects" under "project". var project = window.project || {}; project.arm = project.arm || {}; project.arm.object = (function() { var privateVar = "Private contents."; function privateMethod() { alert(privateVar); } return { method: privateMethod }; }()); Are there any best practices or conventions when defining a complex module structure? Should I just declare a new arm/object underneath the last?

  • How to handle empty return from getJSON

    - by Gee
    Alright so I have a php script which gets results from a DB, and to get those results I'm using a jQuery script to pull the results via getJSON. It works perfectly but now I want to do something if the php script returns no results (empty). I tried: $.getJSON('path/to/script'), {parameter:parameter}, function(data){ if (data) { alert('Result'); } else { alert('Empty); } }); But it's no good. I've tried different things like if (data.length) but still nothing. I've noticed that if there is no returned data the callback will never fire at all. So if that's the case, how do I handle a empty return?

  • Looping through my table, how do I know if the checkbox is checked?

    - by radbyx
    How I build my table: for (var i = 0; i < result.length; i++) { var item = result[i]; // Firma, BygningselementNavn, BrugerNavn, EmailAdresse, Telefon tbody = tbody + '<tr class="modtagerRow"><td>' + item.FirmaNavn + '</td>' + '<td>' + item.BygningselementNavn + '</td>' + '<td>' + item.BrugerNavn + '</td>' + '<td>' + item.EmailAdresse + '</td>' + '<td>' + item.Telefon + '</td>' // Medtag tbody = tbody + '<td style="text-align:center"><input type="checkbox" value="' + item.BygningselementId + '_' + item.BrugerId + '" name="BygningsElementBrugerComboIds"></td>' + '</tr>'; } $('#ModtagereTable tbody').append(tbody) How I am trying to loop through the rows and adding a CSS class to rows that has it's checkbox checked. 1) I get the indexies to the console, but I can't make the if condition for all the checked checkboxes. 2) Also I am not sure if I can you $( this ) or I should use something else, when adding the class .hideForSendMailConfirm? // Looping rows in table $( ".modtagerRow" ).each(function(index, element) { console.log('index: ' + index); // if if (element.checked) { $( this ).addClass(".hideForSendMailConfirm"); } });

  • Internet Explorer and onMouseOver/onMouseOut

    - by Thorbjørn Reimann-Andersen
    Hi all, I have tried looking a similar question on here but couldnt find one so here it comes: I have this html (ignore the "+whatever+@", its in a codebehind file so im putting some variables that im getting from there): <div id='ReferenceContainer"+UniqueID+@"' style='background-color:"+BackcolourOFF+@"; width:"+CompWidth+@"; height:"+CompHeight+@";'> <div id='Reference"+UniqueID+@"' style='width:"+CompWidth+@"; height:"+CompHeight+@"; '> <div id='RefTextContainer"+UniqueID+@"' style='float:left; width:"+CompWidth+@"; height:"+CompHeight+@"; ' > <div id='RefTitleCon' style='margin-top:"+RefTitleMargin+@"px; color:"+RefTitleColor+@"; z-index:-1;' ><p><b>"+RefTitle+@"</b></p> </div> <div id='RefTextCon'><p>"+RefText+@"</p></div> </div> <div id='RefPicContainer"+UniqueID+@"' style='float:right;'> <img id='RefImg"+UniqueID+@"first' class='first' name='RefImg"+UniqueID+@"' src=" + StartImg + @" style='position:absolute;' ></img> <img id='RefImg"+UniqueID+@"second' class='second' name='RefImg"+UniqueID+@"' src=" + AltImg + @" style='display:none;' ></img> </div> </div> <div id='ScriptContainer"+UniqueID+@"' style='width:"+CompWidth+@"; height:"+CompHeight+@"; position:relative; top:-"+CompHeight+@"px; left:0px;' onMouseOver='ChangeBackcolourON"+UniqueID+@"()' onMouseOut='ChangeBackcolourOFF"+UniqueID+@"()'></div> </div> Now in firefox, everything works just perfect. The div "ScriptContainer" sits in front of the whole thing and when the mouse enters or leaves the functions work exactly as they should. But IE8 places the text in front of everything and then the functions do not work as i would like them to. "ChangeBackcolourOFF" gets called every time the mouse enters the text, which sits in front of everything and "ChangeBackcolourON" gets called every time the mouse enters the "Scriptcontainer" from the text. So i either need to figure out how to force the text to be placed behind the "Scriptcontainer" or some other solutions. I appreciate you answers

  • getting started with Google Closure if you don't care about minifying/compiling?

    - by Tim
    If you don't care about minifying your code, is there a way to get started using the Google Closure library without having to set up a subversion client and use the compiler? The Notepad sample program on Google's website refers to <script src="closure-library/base.js" > </script > Can you simply download closure-library/base.js somewhere and start playing with the UI examples? The Closure Lite quick-start version doesn't appear to include goog.ui

  • html - selection range - getting the range + starting node + ending node + distance

    - by sugar
    From my previous question for selecting specific html text, I have gone through this link to understand range in html string. Actually I am confused here very much. My question is as follows. For selecting a specific text on html page. We need to follow this steps. assumed html <h4 id="entry1196"><a href="http://radar.oreilly.com/archives/2007/03/call_for_a_blog_1.html" class="external">Call for a Blogger's Code of Conduct</a></h4> <p>Tim O'Reilly calls for a Blogger Code of Conduct. His proposals are:</p> <ol> <li>Take responsibility not just for your own words, but for the comments you allow on your blog.</li> <li>Label your tolerance level for abusive comments.</li> <li>Consider eliminating anonymous comments.</li> </ol> java script to make selection by range var range = document.createRange(); // create range var startPar = [the p node]; // starting parameter var endLi = [the second li node]; // ending parameter range.setStart(startPar,13); // distance from starting parameter. range.setEnd(endLi,17); // distance from ending parameter range.select(); // this statement will make selection I want to do this in invert way. I mean, assume that selection is done by user on browser (safari). My question is that How can we get starting node ( as we have 'the p node' here ) & ending node ( as we have 'the second li node' here ) and the range as well (as we have 13,17 here) ?

  • Changing a Variable Out of Scope?

    Is there any way to change a variable while out of scope? I know in general, you cannot, but I'm wondering if there are any tricks or overrides. For example, is there any way to make the following work: function blah(){ var a = 1 } a = 2; alert(blah());

  • jQuery server ping slowly but surely filling memory?

    - by danspants
    I use the following piece of code to test if our server is running whilst the user is in a page. I've also started adding other functions that grab small amounts of data that are constantly changing and are to be relayed to the user (Files waiting for download, messages, reports etc). I've noticed recently that if I leave any page open (all pages contain the same function), the browser takes up more and more system memory which I can only attribute to this regular task (overnight it reached 1.6 gb). Is there some way of clearing out the data that is being accumulated? Is this normal behaviour? As far as i can tell, every time I call the function it should overwrite the previously retrieved data? function testServer(){ jQuery.ajax({ type:"HEAD", url:"/media/d_arrow_blue.png", error: function(msg) { jQuery.jGrowl("Server Disconnected"); } }); //retrieves count of files awaiting download - move to seperate function jQuery.get("/get_files/",{"type":"count"},function(data) { jQuery("#downloadList").children("div").text(data); }); }; jQuery().doTimeout(6000,function() { testServer(); return true; });

  • adding a class when link is clicked from Wordpress loop

    - by Carey Estes
    I am trying to isolate and add a class to a clicked anchor tag. The tags are getting pulled from a Wordpress loop. I can write JQuery to remove the "static" class, but it is removing the class from all tags in the div rather than just the one clicked and not adding the "active" class. Here is the WP loop <div class="more"> <a class="static" href="<?php bloginfo('template_url'); ?>/work/">ALL</a> <?php foreach ($tax_terms as $tax_term) { echo '<a class="static" href="' . esc_attr(get_term_link($tax_term, $taxonomy)) . '" title="' . sprintf( __( "View all posts in %s" ), $tax_term->name ) . '" ' . '>' . $tax_term->name.'</a>'; } ?> </div> Generates this html: <div class="more"> <a class="static" href="#">ALL</a> <a class="static" href="#">Things</a> <a class="static" href="#"> More Things</a> <a class="static" href="#">Objects</a> <a class="static" href="#">Goals</a> <a class="static" href="#">Books</a> <a class="static" href="#">Drawings</a> <a class="static" href="#">Thoughts</a> </div> JQuery: $("div.more a").on("click", function () { $("a.static").removeClass("static"); $(this).addClass("active"); }); I have reviwed the other similar questions here and here, but neither solution is working for me. Can this be done with JQuery or should I put a click event in the html inline anchor? It looks like it is working just for a second until the page reloads.

  • Jquery and frames

    - by Shard
    I am currently working on a web application that has been created using a magnitude of frames that stretch down up to 5 times, The issue is that i need to preform some jquery magic throughout the website. What would be the best way to go about this (other than rewriting it which i have considered)? EDIT: The Frame Structure is something along the lines of this: Index.html menu.html banner.html list.html footer.html /lib/index.html header.html body.html footer.html The magic i am referencing is a few hot key shortcuts, find and replace that kind of stuff

  • jQuery: Sort div's according to content of different sub divs

    - by rayne
    I'm trying to create a somewhat complex sorting feature which neither uses divs nor lists. Unfortunately two hours of googling didn't help me. Here is the basic setup of my HTML: <div id="all_elements"> <!-- one element --> <div class="element"> <div class="wrapper"> <a href="/" title="links"> <img src="/img/image.jpg" border="0" alt="image" class="image" /></a> <div class="details"> <h3><a href="/" title="title">Name (Sort Argument 1)</a></h3> <div class="title"><a href="/" title="title">Title (Sort Argument 2)</a></div> <div class="year">2010 (Sort Argumentt 3)</div> <div class="country">Great Britain (Sort Argument 4)</div> </div><!-- details --> </div><!-- wrapper --> </div><!-- element --> </div> <!--all_elements--> The setup is a bit complex, but basically .element is the element that needs to be sorted alphabetically according to either the contents of h3, div.title, div.year or div.country. So the user will be able to view the contents of the site either sorted by name, by year, by country or by title. I have this jQuery snippet from a website, but all my attempts on trying to tell it to use the contents of e.g. h3 to sort have failed. Right now it sorts pretty much randomly. jQuery.fn.sort = function() { return this.pushStack([].sort.apply(this, arguments), []); }; function sortAscending(a, b) { return a.innerHTML > b.innerHTML ? 1 : -1; }; function sortDescending(a, b) { return a.innerHTML < b.innerHTML ? 1 : -1; }; $(document).ready(function() { $("#sort").toggle( function() { $('#all_elements .element').sort(sortDescending).appendTo('#all_elements'); $(this).text("Sort Asc"); }, function() { $('#all_elements .element').sort(sortAscending).appendTo('#all_elements'); $(this).text("Sort Desc"); }); }); How can I customize the function to sort the contents of my h3 or divs?
