  • How long can rails keep Ajax open

    - by Alexey
    My application is suppose to constantly update the page without any user interaction. The criteria is that the page just has to be there, as an extra window on the monitor so the user can see the information get updated real time. I'm using the Ajax in jQuery with Rails, and my question is - how long will the .erb page keep Ajax open? Will there be a point where I have to refresh the page or re-initialize? Or will that won't be a problem at all?

  • Supersized image captions - render outside of JavaScript

    - by Sol
    I am using the jQuery supersized script for a full screen slideshow (not the WordPress plugin as this didn't give me enough control). However, one issue that I am trying to tackle is how to render the image caption text outside of the javascript slides[ ] call - and instead, render them within the page div - to improve SEO on the page. My code works fine right now, images and the caption text are correctly displaying, but looking at the source code, there is very little text outside of the javascript (which is bad for SEO), so I would just like to improve it, if possible. I haven't been able to find any other topic on this subject and so far, I've been unsuccessful at improving on the current code, which is as follows; <!-- Supersized 3.2.7 - By Sam Dunn / One Mighty Roar (www.onemightyroar.com) Released under MIT License / GPL License --> <script type="text/javascript"> var slides=[]; <?php $my_query = new WP_Query ( array( 'post_status' => 'publish', 'post_type' => 'featured', //'numberposts' => 5, 'orderby' => 'menu_order', 'order' => 'ASC', 'showposts' => 50 )); while( $my_query->have_posts() ) : $my_query->the_post(); $slink = get_post_meta($post->ID,'FS_link',true); ?> slides.push({image : '<?php echo get_image_path(get_post_meta($post->ID, 'FS_slideimage_src', true)); ?>', title : '<div class="slidecaptioninside"><h1><?php echo the_title(); ?></h1><p><?php echo strip_tags(get_post_meta($post->ID, 'FS_fitemcaption', true)); ?>...<a href="<?php echo $slink;?>">find out more</a></p></div>', url : '<?php echo $slink;?>'}); <?php endwhile; ?> // start supersized JS $j = jQuery.noConflict(); $j(window).load(function() { $j.supersized({ //Functionality slideshow: 1, // ..... additional functions go here... slide_captions : 1, //Slide caption (Pull from "title" in slides array) slides : slides, slide_links : 'blank', progress_bar : 1, mouse_scrub: 1 }); }); </script> <div id="slidecontainer"> <div id="slidecaption"></div> <!--Thumbnail Navigation--> <div id="prevthumb"></div> <div id="nextthumb"></div> <!--additional tray divs here--> </div><!--slidecontainer--> I have tried to get Supersized to output the content into a parent div [div id="supersized"] using $j('#supersized').supersized({ but this doesn't appear to work. Has anyone managed to do this differently to improve page SEO?

  • How to get this JavaScript class member to return a value?

    - by George Edison
    I have a JavaScript class that has a method: function someClass() { this.someMethod = someClass_someMethod; } function someClass_someMethod() { // make an AJAX request } The problem is that someClass_someMethod() needs to return the value of the AJAX request. I'm using jQuery's $.getJSON() method to fetch the data. The data needs to be returned but it seems the only way to get the data is through a callback. How can this be done?

  • Serializing form data with field names that have dots in them.

    - by Dave
    Does the serialize function in jQuery replace dots ('.') with underscores? For example, I have a form field such as: <input id="Project.name" name="Project.name" type="text"> When the form is POSTed, I'm serializing the form data and sending it to another PHP file to save. The dots seem to be converted to underscores. Is this normal behavior?

  • Simple Modal with Autocomplete in ASP.NET

    - by DanielJaymes
    Hello, I am quite new to this so any help is very much appreciated. I am generating a modal pop using Simple Modal, this works ok. I now want to add jquery autocomplete to the element txtEmail. When I run the page outside of Simple Modal I can use Autocomplete, however when the page is loaded through Simple Modal it does not work. I have checked to ensure the element is loaded, and it is allowing me to change the text color, but I can not add autocomplete to it. The code is /** * @author Daniel */ jQuery(function($) { $("input.ema, a.ema").click(function(e) { e.preventDefault(); $("#osx-modal-content").modal({ appendTo: 'form', overlayId: 'osx-overlay', containerId: 'osx-container', closeHTML: '<div class="close"><a href="#" class="simplemodal-close">X</a></div>', minHeight: 80, opacity: 65, position: ['0', ], overlayClose: true, onOpen: OSX.open, onClose: OSX.close, onShow: OSX.show }); }); var OSX = { container: null, open: function(d) { var self = this; $.ajax({ url: "/Message/UserMessage/", type: 'GET', dataType: 'html', // <-- to expect an html response success: function(result) { var data = "Core Selectors Attributes Traversing Manipulation CSS Events Effects Ajax Utilities".split(" "); $('div#osx-modal-data').html(result).find("#txtEmail").css('color', '#c00'); if ($('div#osx-modal-data').find("#txtEmail").length) { // implies *not* zero $('div#osx-modal-data').find("#txtEmail").autocomplete(data); alert('We found img elements on the page using "img"'); } else { alert('No txtEmail elements found'); } } }); self.container = d.container[0]; d.overlay.fadeIn('slow', function() { $("#osx-modal-content", self.container).show(); $('div#osx-modal-title').html("Send Email"); var title = $("#osx-modal-title", self.container); title.show(); d.container.slideDown('slow', function() { setTimeout(function() { var h = $("#osx-modal-data", self.container).height() + title.height() + 20; // padding d.container.animate({ height: h }, 200, function() { $("div.close", self.container).show(); $("#osx-modal-data", self.container).show(); }); }, 300); }); }) }, close: function(d) { var self = this; d.container.animate({ top: "-" + (d.container.height() + 20) }, 500, function() { self.close(); // or $.modal.close(); }); }, show: function(d) { // $('div#osx-modal-data').find("#txtEmail").css('color', '#ccc') } }; });

  • Is there a way to clear all JavaScript timers at once?

    - by Jens
    Im building an automatic refreshing comment section for my website using jQuery .load. So I am using a javascript 'setTimeout' timer to check for new comments. But after doing some stuff like changing comment pages or deleting (all using ajax), a few old timers keep running, even though I used clearTimeout before loading new ajax content. Is there some way to clear ALL javascript timers when I load new ajax content?

  • JavaScript - Efficiently find all elements containing one of a large set of strings

    - by noah
    I have a set of strings and I need to find all all of the occurrences in an HTML document. Where the string occurs is important because I need to handle each case differently: String is all or part of an attribute. e.g., the string is foo: <input value="foo"> - Add class ATTR to the element. String is the full text of an element. e.g., <button>foo</button> - Add class TEXT to the element. String is inline in the text of an element. e.g., <p>I love foo</p> - Wrap the text in a span tag with class TEXT. Also, I need to match the longest string first. e.g., if I have foo and foobar, then <p>I love foobar</p> should become <p>I love <span class="TEXT">foobar</span></p>, not <p>I love <span class="TEXT">foo</span>bar</p>. The inline text is easy enough: Sort the strings descending by length and find and replace each in document.body.innerHTML with <span class="TEXT">$1</span>, although I'm not sure if that is the most efficient way to go. For the attributes, I can do something like this: sortedStrings.each(function(it) { document.body.innerHTML.replace(new RegExp('(\S+?)="[^"]*'+escapeRegExChars(it)+'[^"]*"','g'),function(s,attr) { $('[+attr+'*='+it+']').addClass('ATTR'); }); }); Again, that seems inefficient. Lastly, for the full text elements, a depth first search of the document that compares the innerHTML to each string will work, but for a large number of strings, it seems very inefficient. Any answer that offers performance improvements gets an upvote :)

  • How can I dynamically load and execute all of the Javascript files in a directory?

    - by Andrew
    I'm making a very simple content-management system in Javascript. It uses plugins which are individual .js files which live in a "modules" folder. Currently I'm loading them with JQuery's getScript() function, but I have to manually define the list of available modules. Is there any way to dynamically load the list of Javascript files so that the user can install additional modules by simply dropping them into the "modules" folder?

  • Slider with buttons. How to improve?

    - by Kalinin
    I need to make slider. I have content (which should shift horizontally) and two buttons - "right" and "left". If you press the button and hold it, the content starts to move (in the appropriate direction). If you not hold the button, then the movement stops. This behavior is copies the behavior of usual window scrollbar. I wrote code: var animateTime = 1, offsetStep = 5; //event handling for buttons "left", "right" $('.bttR, .bttL') .mousedown(function() { scrollContent.data('loop', true).loopingAnimation($(this)); }) .bind("mouseup mouseout", function(){ scrollContent.data('loop', false); }); $.fn.loopingAnimation = function(el){ if(this.data('loop') == true){ var leftOffsetStr; leftOffsetInt = parseInt(this.css('marginLeft').slice(0, -2)); if(el.attr('class') == 'bttR') leftOffsetStr = (leftOffsetInt - offsetStep).toString() + 'px'; else if(el.attr('class') == 'bttL') leftOffsetStr = (leftOffsetInt + offsetStep).toString() + 'px'; this.animate({marginLeft: leftOffsetStr}, animateTime, function(){ $(this).loopingAnimation(el); }) } return this; } But it does have a few things that I do not like: Always call the function animation (loopingAnimation) - I think that this is an extra load (not good). When moving content he "twitches and trembling" - (it's not pretty). How can I solve this problem more elegantly and without the drawbacks of my code?

  • HTML - Which element to output text?

    - by Oliver Weiler
    I'm implementing a little chat application where I receive messages from a server, which I would like to display to a user. As I'm more of a backend guy, and lacking experience in frontend development, I don't know which element would be suited best to output the text. Two options come to my mind: Using a plain div Using a textarea (as far as I understand, this is intended to be used for input). (Would also be nice if I could somehow fade in the text using JQuery).

  • How to access child element out of children()?

    - by user291701
    Hi, I'd like to get the # of immediate children an element has, and then get the class of a child at a particular index. Something like: var index = 25; var children = $("#myListElement").children(); if (index < children.length) { if (children[index].hasClass("testClass")) { alert("hi!"); } } I think the syntax for .children() is ok, but how do I get the indexed element out of them in jquery style? Thanks

  • Validation and Firefox's input caching

    - by Chris Simpson
    When you refresh/reload a page or use the back button, Firefox is kind enough to repopulate your inputs with what was entered before you navigated away. Though this is a nice feature it does not trigger my jquery validation and the unsaved changes warning I add to my pages. Is there a way to either disable this feature in Firefox (without renaming every control every time) or capture the firefox events?

  • Moving an element with InsertAfter, but only insert it the parent of the elements?

    I did the following: jQuery('.businessdirectory-category .wpbdp-rating-info').insertAfter('.businessdirectory-category .title'); To move .wpbdp-rating-info after .title. But there are 3 .wpbdp-rating-info in the page so now each .businessdirectory-category has 3 .wpbdp-rating-info How can I do it so that each .businessdirectory-category only has its own .wpbdp-rating-infoappended to its own.title`?

  • Simple html page using Bootstrap

    - by Athashri
    I am writing a simple HTML page using the Twitter Bootstrap. But the navbar and links are rendered as normal HTML on the browser. I have referred to multiple sites but the same steps are given everywhere. I am not sure where I am going wrong. Code: <!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <link rel= "stylesheet" href= "css/bootstrap.css" type="text/css"> <title> Bootstrap example</title> </head> <body> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script src="js/bootstrap.js"></script> <h1>Hello, world!</h1> <div class ="container"> <h1><a href="#">Bootstrap Site</a></h1> <div class="navbar"> <div class="navbar-inner"> <div class="container"> <ul class="nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Projects</a></li> <li><a href="#">Services</a></li> <li><a href="#">Downloads</a></li> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> </ul> </div> </div> </div> </div> </body> </html>

In both cases, if I inspect element, I can see the "shadow" of the full picture, at the right size, with the right url. Image source doesnt' seem to make a difference, I'm getting no errors, and this is happening in both chrome and firefox. Does anyone have any ideas?
