  • Should image size be defined in the img tag height/width attributes or in CSS?

    - by Benjamin Manns
    Is it better coding practice to define an images size in the img tag's width and height attributes? <img src="images/academia_vs_business.png" width="740" height="382" alt="" /> Or in the CSS style with width/height? <img src="images/academia_vs_business.png" style="width:740px; height:382px;" alt="" /> Or both? <img src="images/academia_vs_business.png" width="740" height="382" style="width:740px; height:382px" alt="" />

  • Are there any drawbacks to class-based Javascript injection?

    - by jonathanconway
    A phenomena I'm seeing more and more of is Javascript code that is tied to a particular element on a particular page, rather than being tied to kinds of elements or UI patterns. For example, say we had a couple of animated menus on a page: <ul id="top-navigation"> ... </ul> <!-- ... --> <ul id="product-list"> ... </ul> These two menus might exist on the same page or on different pages, and some pages mightn't have any menus. I'll often see Javascript code like this (for these examples, I'm using jQuery): $(document).ready(function() { $('ul#top-navigation').dropdownMenu(); $('ul#product-selector').dropdownMenu(); }); Notice the problem? The Javascript is tightly coupled to particular instances of a UI pattern rather than the UI pattern itself. Now wouldn't it be so much simpler (and cleaner) to do this instead? - $(document).ready(function() { $('ul.dropdown-menu').dropdownMenu(); }); Then we can put the 'dropdown-menu' class on our lists like so: <ul id="top-navigation" class="dropdown-menu"> ... </ul> <!-- ... --> <ul id="product-list" class="dropdown-menu"> ... </ul> This way of doing things would have the following benefits: Simpler Javascript - we only need to attach once to the class. We avoid looking for specific instances that mightn't exist on a given page. If we remove an element, we don't need to hunt through the Javascript to find the attach code for that element. I believe techniques similar to this were pioneered by certain articles on alistapart.com. I'm amazed these simple techniques still haven't gained widespread adoption, and I still see 'best-practice' code-samples and Javascript frameworks referring directly to UI instances rather than UI patterns. Is there any reason for this? Is there some big disadvantage to the technique I just described that I'm unaware of?

  • Web based weekly planner

    - by Calum
    Hello I'm looking to implement a web based weekly planner where a user can set when they will be unavailable to work. The state of the week will be saved as a 'varbinary' with a length of 168 which will represent every hour of everyday of a week. The database only needs to store the value of one week as the times unavailable to work will be the same each week. I'm looking for a quick and effective method, possibly based on jquery. Thanks

  • Unobtrusive, self-hosted comments function to put onto existing web pages

    - by Pekka
    I am building a new site which will consist of a mix of dynamic and static pages. I would like to add commenting functionality to those pages with as little work as possible. I'm curious as to whether such a solution exists in PHP. The ideal set of features would be: Completely independent from the surrounding page / site: PHP code gets dropped into page, a page ID is added, done. Simple "write a comment" form Comments for each page are displayed using a PHP function Nice, clean output of <ul><li>.... that can be styled by the surrounding site Optional Captcha Optional Gravatar sensitivity Minimalistic administration area to moderate/delete comments, no ACL, can protect it using .htaccess The ideal integreation would be like this: <?php show_comments("my_page_name"); ?> this would 1. display a form to add a new comment that gets automatically associtated with my_page_name; and 2. display all comments that were made through this form using this ID. Does anybody know a solution like this? Bounty I am setting up a bounty because while there were some good suggestions, they all point to external services. I'm really curious to see whether there isn't anything self-hosted around. If this doesn't exist yet, it sure would be great to see as an Open Source project.

  • Using JavaScript's split to chop up a string and put it in two arrays

    - by Pieter
    I can use JavaScript's split to put a comma-separated list of items in an array: var mystring = "a,b,c,d,e"; var myarray = mystring.split(","); What I have in mind is a little more complicated. I have this dictionary-esque string: myvalue=0;othervalue=1;anothervalue=0; How do I split this so that the keys end up in one array and the values end up in another array?

  • Accomplishing This Style of Drop-Down Menus in jQuery

    - by Maxim Z.
    I was browsing the web and found this site. I noticed how the nav bar drop-down works, and I want to implement something similar on my website. Afer going into the source code of the page, I found that those drop-down areas are contained in divs with class fOut. It turns out that this is being done with MooTools. Here is the script itself (referenced in the original page after the Mootools script itself): window.addEvent('domready', function() { $("primaryNav").getChildren("li").addEvents({ "mouseenter": function(){ $(this).addClass("hover").getChildren("a").addClass("hover"); }, "mouseleave": function(){ $(this).removeClass("hover").getChildren("a").removeClass("hover"); } }); $$(".fOut").each(function(el,i){ var ifr = $(document.createElement("iframe")); ifr.className = "ieBgIframe"; ifr.frameBorder = "0"; ifr.src="about:blank"; ifr.injectInside(el); var p = el.getParent(); p.addClass("hover"); var h = el.getSize().size.y; p.removeClass("hover"); ifr.height=h; }); $$(".olderVersionsToggle").addEvents({ "click": function(e){ var event = new Event(e); event.stop(); var p = $(this).getParent().getNext(); if(p.hasClass("open")){ p.removeClass("open"); $(this).setText("Show previous versions..."); } else{ p.addClass("open"); $(this).setText("Hide previous versions..."); } return false; } }); }); My Question(s) I have two questions about this code. How does it work? I don't quite understand what it's doing, with the iframes and all. How can this be implemented in jQuery?

  • id vs class selection benchmark

    - by zaf
    Has anybody bench marked selecting elements with id's and class's from CSS and javascript? It would make sense that an element with an id is faster to select than if it had a class even if it was the only element with that class. Do I really need to be concerned?

  • Editing Neo Slider to move in one direction

    - by user2106416
    I have a website with brandspace theme from pixelentity. Currently, the slider move from right to left ( auto transition) . But, when the slider reaches the last image, it will go back to the first image by making all previous images sliding back from left to right. I want to make the slider to have a normal transition,i.e. going back to first image but still with the image sliding from right to left. Below is the slider.php code.: <?php $t =& peTheme(); ?> <?php list($pid,$conf,$loop) = $t->template->data(); ?> <?php $w = $t->media->width(940); ?> <?php $h = $t->media->height(300); ?> <div class="peSlider peVolo" data-autopause="disabled" data-plugin="<?php echo apply_filters("pe_theme_slider_plugin","peVolo"); ?>" data-controls-arrows="edges-full" data-controls-bullets="disabled" data-icon-font="enabled"> <?php while ($slide =& $loop->next()): ?> <?php $link = empty($slide->link) ? false: $slide->link; ?> <?php $img = $t->image->resizedImg($slide->img,$w,$h); ?> <div data-delay="4" <?php echo $slide->idx == 0 ? ' class="visible"' : ''; ?>> <?php if (isset($slide->caption)) $t->slider->caption($slide->caption); ?> <?php if ($link): ?> <a href="<?php echo $link ?>" data-flare-gallery="fsGallery<?php echo $pid ?>"> <?php echo $img; ?> </a> <?php else: ?> <?php echo $img; ?> <?php endif; ?> </div> <?php endwhile; ?> </div>

  • browser back acts on nested iframe before the page itself - is there a way to avoid it??

    - by kfiroo
    hi, i have a page with dynamic data loaded by some ajax and lots of javascript. the page contains a list from which the user can choose and each selected value loads new data to the page. one of these data items is a url provided to an iframe. i use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior. all works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then i need to click back again to make the page go back. is there a way to disable the iframe's back behavior?

  • Background Image comes up as white when displayed using Javascript

    - by AndroidNewbie
    I am trying to change the background image whenever the document is loaded, and when it hits this point: document.body.style.backgroundImage="url('../images/mobile-bckground.png')"; The page simply makes the background plain white. It is displayed like this in my javascript: $(function() { document.body.style.backgroundImage="url('../images/mobile-bckground.png')"; }); I have verified the image is in the right location, why is it doing this?

  • Changing <img src="XXX" />, js event when new image has finished loading?

    - by carillonator
    I have a photo gallery web page where a single <img src="XXX" /> element's src is changed (on a click) with javascript to show the next image—a poor man's ajax I guess. Works great on faster connections when the new image appears almost immediately. Even if it takes a few seconds to load, every browser I've tested it on keeps the old image in place until the new one is completely loaded. It's a little confusing waiting those few seconds on a slow connection, though, and I'm wondering if there's some javascript event that fires when the new image is done loading, allowing me to put a little working... animated gif or something up in the meantime. I know I could use AJAX for real (I'm using jQuery already), but this is such a nice and simple solution. Besides this lag, is there any other reason I should stay away from this approach to changing images? thanks.

  • "Outward" border-radius in css?

    - by MaxMackie
    Currently, the links at the top of my website look like this: However, I am trying to "round" the bottom edges of the buttons to make it look like they are coming out of the page and into the ribbon at the top. I am aware that you can hack it and add a "separator" div with rounded corners between each entry, but this would be difficult to do seeing at the borders used are not all from the same div. Also, it wouldn't be easy seeing as my buttons are very close to each other. The css for the "button": .button { border-top: 3px solid #A1C1BE; border-left: 3px solid #A1C1BE; border-right: 3px solid #A1C1BE; border-bottom: 0px; padding: 5px 8px 5px 8px; margin: 0 0 -9px 0; border-radius: 5px 5px 0 0; font-size: 12px; font-family: 'PT Sans', sans-serif; background-color: #f8f8ff; color: #484848; } css for the "ribbon": #top-wrapper { border-bottom: 5px solid #A1C1BE; width: 100%; background-color: #59554E; padding: 10px 0 0 0; color: #C0C0A8; } As you can see, the thicker border belongs to the ribbon which stretches the length of the webpage, whereas the thinner blue border is part of the button.

  • jquery - problem with executing annimation of two separate objects, one after another

    - by MoreThanChaos
    Hello I have problem to put together animations of two separate objects to second one start when first one ends. I tried to use callback but it seems that i make some syntax misteakes which crash jQuery or cause some unexpected behaviour. It seems that i'm stuck so I'd like to ask You for best way to put these animations together to act the way I want. in mouseenter 1st .pp grows, 2nd .tt fade in in mouseleave 1st .tt fade out, 2nd .pp shrink It's alsp relevant that animations doesn't pile up, i mean here animation called by one event doesnt wait until other animation in progress will end. In generall exactly what is below but yo be animated one after another, not simultanously. $('.pp').bind({ mouseenter: function() { $(this).animate({ width: $(this).children(".tt").outerWidth(), height: $(this).children(".tt").outerHeight() },{duration:1000,queue:false} ); $(this).children(".tt").animate({ opacity: 1.0 }, {duration:1000,queue:false}); }, mouseleave: function() { $(this).children(".tt").animate({ opacity: 0 }, {duration:1000,queue:false}); $(this).animate({ width: 17, height: 17 }, {duration:1000,queue:false}); } });
