  • How do i make a allocation table?

    - by david
    I have build a grid of div's as playground for some visual experiments. In order to use that grid, i need to know the x and y coordinates of each div. That's why i want to create a table with the X and Y position of each div. X:0 & Y:0 = div:eq(0), X:0 Y:1 = div:eq(1), X:0 Y:2 = div:eq(2), X:0 Y:3 = div:eq(3), X:1 Y:0 = div:eq(4) etc.. What is the best way to do a table like that? Creating a OBJECT like this: { 00: 0, 01: 1, 02: 2, etc.. } or is it better to create a array? position[0][0] = 0 the thing is i need to use the table in multiple way's.. for example the user clicked the div nb: 13 what are the coordinates of this div or what is the eq of the div x: 12 y: 5. Thats how i do it right now: var row = 0 var col = 0 var eq = 0 c.find('div').each(function(i){ // c = $('div#stage') if (i !=0 && $(this).offset().top != $(this).prev().offset().top){ row++ col = 0 } $(this).attr({'row': row, 'col': col }) col++ }) I think it would be faster to build a table with the coordinates, instead of adding them as attr or data to the DOM. but i cant figure out how to do this technically. How would you solve this problem width JS / jQuery?

  • TinyMce imagemanager won't generate image path when used with an iframe

    - by Tom
    I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

  • Injecting jQuery into a page fails when using Google AJAX Libraries API

    - by jakemcgraw
    I'd like to inject jQuery into a page using the Google AJAX Libraries API, I've come up with the following solution: http://my-domain.com/inject-jquery.js: ;((function(){ // Call this function once jQuery is available var func = function() { jQuery("body").prepend('<div>jQuery Rocks!</div>'); }; // Detect if page is already using jQuery if (!window.jQuery) { var done = false; var head = document.getElementsByTagName('head')[0]; var script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.onload = script.onreadystatechange = function(){ // Once Google AJAX Libraries API is loaded ... if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) { done = true; // ... load jQuery ... window.google.load("jquery", "1", {callback:function(){ jQuery.noConflict(); // ... jQuery available, fire function. func(); }}); // Prevent IE memory leaking script.onload = script.onreadystatechange = null; head.removeChild(script); } } // Load Google AJAX Libraries API head.appendChild(script); // Page already using jQuery, fire function } else { func(); } })()); The script would then be included in a page on a separate domain: http://some-other-domain.com/page.html: <html> <head> <title>This is my page</title> </head> <body> <h1>This is my page.</h1> <script src="http://my-domain.com/inject-jquery.js"></script> </body> </html> In Firefox 3 I get the following error: Module: 'jquery' must be loaded before DOM onLoad! jsapi (line 16) The error appears to be specific to the Google AJAX Libraries API, as I've seen others use a jQuery bookmarklet to inject jQuery into the current page. My question: Is there a method for injecting the Google AJAX Libraries API / jQuery into a page regardless of the onload/onready state?

  • Jquery - binding click event to a variable

    - by Kayote
    All, I am really stuck/ confused at this point. I have an array with 6 items in it. Each item in the array is dynamically filled with elements using jquery '.html' method. However, I cannot seem to be able to attach/ bind an event to this dynamically created variable. As soon as the browser gets to the problem line (see the area labeled 'PROBLEM AREA'), I get a 'undefined' error, which is really confusing as all the previous code on the very same variable works just fine. var eCreditSystem = document.getElementById("creditSystem"); var i = 0; var eCreditT = new Array(6); // 6 members created which will be recycled function createCreditTransaction () // func called when a transaction occurs, at the mo, attached to onclick() { if (i < 6) { eCreditT[i] = undefined; // to delete the existing data in the index of array addElements (i); } else if (i > 5 || eCreditT[i] != undefined) { ... } } function addElements (arrayIndex) // func called from within the 'createCreditTransaction()' func { eCreditT[i] = $(document.createElement('div')).addClass("cCreditTransaction").appendTo(eCreditSystem); $(eCreditT[i]).attr ('id', ('trans' + i)); $(eCreditT[i]).html ('<div class="cCreditContainer"><span class="cCreditsNo">-50</span>&nbsp;<img class="cCurrency" src="" alt="" /></div><span class="cCloseMsg">Click box to close.</span><div class="dots"></div><div class="dots"></div><div class="dots"></div>'); creditTransactionSlideOut (eCreditT[i], 666); // calling slideOut animation console.log(eCreditT[i]); // this confirms that the variable is not undefined /* ***** THE PROBLEM AREA ***** */ $(eCreditT[i]).on ('click', function () // if user clicks on the transaction box { creditTransactionSlideBackIn (eCreditT[i], 150); // slide back in animation }); return i++; }

  • JQuery fadeIn after src changed but fadeIn on the previous src anyway !

    - by Anna
    Hello ! I have a jquery bug and I've been looking for hours now, I can't figure out what's wrong... I have this code : $(document).ready(function(){ $('#ulPhotos a').click(function() { var newSrc= $(this).find('img').attr('src').split("/"); bigPictureName = 'big'+newSrc[2]; $('#pho').hide(); $('#imageBig').attr("src", "images/photos/"+bigPictureName); $('#pho').fadeIn('slow'); var alt = $(this).find('img').attr('alt'); $('#legend').html(alt); }); }); and this in html : <ul id="ulPhotos"> <li><a href="#centre"><img src="images/photos/09.jpg" title="La Reine de la Nuit au Comedia" alt="<em>La Reine de la Nuit</em> au Comedia"/></a> <a href="#centre"><img src="images/photos/03.jpg" title="Manuelita, La Périchole à l&rsquo;Opéra Comique" alt="Manuelita, <em>La Périchole</em> à l&#8217;Opéra Comique" /></a></li> <li><a href="#centre" ><img src="images/photos/12.png" title="" alt="Marion Baglan Carnac Ré" /></a> and this in for bigImage : </div> <div id="pho" a name="centre"> <p id="legend"> La Reine de la Nuit</p> <img src="images/photos/big09.jpg" alt="Marion Baglan" id="imageBig"/> </div> It simply changes the source of my img in a div named pho... but sometimes when the new image is too heavy, the fadeIn executes on the previous src !! so we see the fadeIn first on the previous image, and then, the right picture appears without fadeIn.... am I missing something? ps : the page is here http://www.marion-baglan.net/photos.htm#centre if you click fast you can see it... and when I try to put some bigger photos, it's very obvious...

  • Prepending items in serialscroll

    - by Zack
    Hi, I am using serialscroll plugin for jquery by Ariel Flesler. I am trying to make the vertical scroller to have continues loop without reverting back to first item (which is default functionality). To have continues loop of items i tried to append the items which is working fine and able to achieve when i click on "NEXT". However problem seems to be with "Previous" link where i am trying to prepend the items at the top, it is pending the items however changing the visible items. I understand that prepending the items is causing the index of items to change which is normal. So what i am looking for it to keep showing the visible items even when prepending. Please see this URL where i have put the problem i am facing : http://www.resourceskit.com/test/ Please suggest. Thanks

  • Raphael SVG VML Implement Multi Pivot Points for Rotation

    - by Cody N
    Over the last two days I've effectively figured out how NOT to rotate Raphael Elements. Basically I am trying to implement a multiple pivot points on element to rotate it by mouse. When a user enters rotation mode 5 pivots are created. One for each corner of the bounding box and one in the center of the box. When the mouse is down and moving it is simple enough to rotate around the pivot using Raphael elements.rotate(degrees, x, y) and calculating the degrees based on the mouse positions and atan2 to the pivot point. The problem arises after I've rotated the element, bbox, and the other pivots. There x,y position in the same only there viewport is different. In an SVG enabled browser I can create new pivot points based on matrixTransformation and getCTM. However after creating the first set of new pivots, every rotation after the pivots get further away from the transformed bbox due to rounding errors. The above is not even an option in IE since in is VML based and cannot account for transformation. Is the only effective way to implement element rotation is by using rotate absolute or rotating around the center of the bounding box? Is it possible at all the create multi pivot points for an object and update them after mouseup to remain in the corners and center of the transformed bbox?

  • firefox reading web page from local JS file -- access to restricted URI denied, code: 1012, nsresult

    - by macias
    My problem is -- I have a html file which is really JS program, which reads web pages and show them in customized manner (i.e. it displays the same content in a different way). Basically, I create XMLHttpRequest object and then req.open("GET", web_page_address, false); req.send(""); This gives me (in firefox) an error: Error: uncaught exception: [Exception... "Access to restricted URI denied" code: "1012" nsresult: "0x805303f4 (NS_ERROR_DOM_BAD_URI)" I already googled, and looked at SO but all other issues are very similar with those two exceptions: the file I open in firefox is a local file, opened directly in browser -- I don't have www server running at localhost I don't have any control over the web pages I am reading stuff from So, several solutions I've seen so far (like adding PHP proxy, changing the way external server sends data) cannot be applied here. What else can be done in such case? Another story is I am wondering if such strict security for directly local file has any sense. Thank you in advance for tips/links/etc. Have a nice day!

  • Google Maps: How does Trulia create their custom InfoWIndows?

    - by NickT
    I really like how Trulia.com has created their custom Google Map InfoWindows. What I like in particular about Trulia's implementation of the InfoWindow is: Extends beyond the map border: Google Maps InfoWindows are contained within the map border whereas Trulia's seems to be able to float on-top of the map Always displays InfoWindow near map Center: Google Maps InfoWindows always display the InfoWindow above the marker whereas Trulia InfoWindows always display the InfoWindow as close the center of the map as possible. For example, if the map marker icon is on the top of the map near the border, the Trulia InfoWindow is displayed below the map marker icon InfoWindow is displayed on mouse hover (not 'click'): With the default Google Maps InfoWindow, you have to 'click' the map marker icon to display the InfoWindow whereas Trulia InfoWindows are display simply by hovering over the map marker icon. I found the PdMarker, which is a 3rd party extension for Google Map InfoWindows that accomplishes most of the above bullets but not all. 1) It does not extend beyond the map border, 2) it does not work with Google Maps API version 3 (only version 2). Anyone know how Trulia is accomplishing their InfoWindow-like implementation on Google Maps API v3?

  • best way to add and delete text lines with jquery product configurator

    - by Daniel White
    I am creating a product configurator with Jquery. My users can add custom text lines to their product. So you could create say... 4 text lines with custom text. I need to know what the best way to add and delete these lines would be. Currently I have the following code for adding lines... //Add Text Button $('a#addText').live('click', function(event) { event.preventDefault(); //Scroll up the text editor $('.textOptions').slideUp(); $('#customText').val(''); //count how many items are in the ul textList var textItems = $('ul#textList li').size(); var nextNumber = textItems + 1; if(textItems <= 5) { //Change input to reflect current text being changed $('input#currentTextNumber').val(nextNumber); //Append a UL Item to the textList $('ul#textList').append('<li id="textItem'+nextNumber+'">Text Line. +$5.00 <a class="deleteTextItem" href="'+nextNumber+'">Delete</a></li>'); //Scroll down the text editor $('.textOptions').slideDown(); }else { alert('you can have a maximum of 6 textual inputs!'); } }); I'm probably not doing this the best way, but basically i have an empty UL list to start with. So when they click "Add Text Line" it finds out how many list elements are in the unordered list, adds a value of 1 to that and places a new list element with the id TextItem1 or TextItem2 or whatever number we're on. The problem i'm running into is that when you click delete item, it screws everything up because when you add an item again all the numbers aren't correct. I thought about writing some kind of logic that says all the numbers above the one you want deleted get 1 subtracted from their value and all the numbers below stay the same. But I think i'm just going about this the wrong way. Any suggestions on the easiest way to add and delete these text lines is appreciated.

  • Trigger function when mouse click inside textarea AND type stop typing...

    Welcome, In short, my website use BBcode system, and i want allow users to preview message without posting it. I'm using JQuery library. I need 3 actions. 1) When user click in textarea i want display DIV what will contain preview, i want animate opening. 2) When user typing, i want dynamical load parsed by PHP code to DIV. (i'm still thinking what will be best option... refresh every 2 seconds, or maybe we can detect and refresh after 1 second of inactivity [stop typing]) 3) When user click outside textarea i want close preview div with animation. For example the PHP parser will have patch /api/parser.php and variable by POST called $_POST['message']. Any idea my digital friends ?

  • How to get rid of Internet Explorer 7 reloading on fragment change

    - by Philippe Beaudoin
    I have an anchor <a href="#!admin">General</a> somewhere in my page. Clicking this in any browser but IE7 (haven't tried IE6) causes no page reload, as expected. However, under IE7 it reloads the page as soon as it's clicked. The strangest thing is that I have the exact same anchor elsewhere in the page and it causes no reload. The only difference I can see between these is a slight difference in style, and the fact that the faulty anchor is deeply nested in divs, where the other is closer to the top. My questions: Is this a known bug with IE7? If so, is there any work around? If not, any clue as to what might be going wrong? Edit: If you want to see this yourself, go to http://filouguestbook.appspot.com/#!main sign-in with a google account and click on the Settings link the the top bar. Switch between the General and Accounts pages, the app will reload. From the Accounts page, click on Settings in the top bar, this will switch tab but not reload!

  • The backbone router isn't working properly

    - by user2473588
    I'm building a simple backbone app that have 4 routes: home, about, privacy and terms. But after setting the routes I have 3 problems: The "terms" view isn't rendering; When I refresh the #about or the #privacy page, the home view renders after the #about/#privacy view When I hit the back button the home view never renders. For example, if I'm in the #about page, and I hit the back button to the homepage, the about view stays in the page I don't know what I'm doing wrong about the 1st problem. I think that the 2nd and 3rd problem are related with something missing in the home router, but I don't know what is. Here is my code: HTML <section class="feed"> <script id="homeTemplate" type="text/template"> <div class="home"> </div> </script> <script id="termsTemplate" type="text/template"> <div class="terms"> Bla bla bla bla </div> </script> <script id="privacyTemplate" type="text/template"> <div class="privacy"> Bla bla bla bla </div> </script> <script id="aboutTemplate" type="text/template"> <div class="about"> Bla bla bla bla </div> </script> </section> The views app.HomeListView = Backbone.View.extend({ el: '.feed', initialize: function ( initialbooks ) { this.collection = new app.BookList (initialbooks); this.render(); }, render: function() { this.collection.each(function( item ){ this.renderHome( item ); }, this); }, renderHome: function ( item ) { var bookview = new app.BookView ({ model: item }) this.$el.append( bookview.render().el ); } }); app.BookView = Backbone.View.extend ({ tagName: 'div', className: 'home', template: _.template( $( '#homeTemplate' ).html()), render: function() { this.$el.html(this.template(this.model.toJSON())); return this; } }); app.AboutView = Backbone.View.extend({ tagName: 'div', className: 'about', initialize:function () { this.render(); }, template: _.template( $( '#aboutTemplate' ).html()), render: function () { this.$el.html(this.template()); return this; } }); app.PrivacyView = Backbone.View.extend ({ tagName: 'div', className: 'privacy', initialize: function() { this.render(); }, template: _.template( $('#privacyTemplate').html() ), render: function () { this.$el.html(this.template()); return this; } }); app.TermsView = Backbone.View.extend ({ tagName: 'div', className: 'terms', initialize: function () { this.render(); }, template: _.template ( $( '#termsTemplate' ).html() ), render: function () { this.$el.html(this.template()), return this; } }); And the router: var AppRouter = Backbone.Router.extend({ routes: { '' : 'home', 'about' : 'about', 'privacy' : 'privacy', 'terms' : 'terms' }, home: function () { if (!this.homeListView) { this.homeListView = new app.HomeListView(); }; }, about: function () { if (!this.aboutView) { this.aboutView = new app.AboutView(); }; $('.feed').html(this.aboutView.el); }, privacy: function () { if (!this.privacyView) { this.privacyView = new app.PrivacyView(); }; $('.feed').html(this.privacyView.el); }, terms: function () { if (!this.termsView) { this.termsView = new app.TermsView(); }; $('.feed').html(this.termsView.el); } }) app.Router = new AppRouter(); Backbone.history.start(); I'm missing something but I don't know what.

  • Programmatically determine DPI via the browser?

    - by Brandon Pelfrey
    Hi all. I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this?

    What's the difference between these setInterval calls and which ones should be used? setInterval("myFunction()",1000) setInterval("myFunction",1000) setInterval(myFunction(),1000) setInterval(myFunction,1000) My guess is that JS uses eval() on the first two (strings) and calls the latter two directly. Also, I don't understand the difference between the calls with and without parentheses. The ones with parentheses call it directly and then periodically call its return value?

  • How to select the first property with unknown name and first item from array in JSON

    - by Oscar Godson
    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']
