  • Jquery - intercept links created by ajax request

    - by Kaskade
    Hi, I have some jquery code that intercepts links clicked on a page : $(document).ready(function() { $("a").click(function() { //do something here }); }); My problem is there are certain parts of the page that have not finished loading on document ready. They are populated via ajax calls. The links in these sections are not intercepted by my jQuery function above. I need the function to be run on document ready initially but then I need the new links to also have the same logic applied to them. Any help would be very much appreciated. This is an area that I am very unfamiliar with. I have written the jQuery stuff but the ajax code is an external component that I have no control over. Thanks in advance

  • Hiding a button on pushed view and showing it when back to list view

    - by torr
    When I load my list view it has several blog posts and a refresh button on the top left. If I tap on a list item a view is pushed with the contents of that specific post. When this view is pushed in, the refresh button is hidden. But when I tap 'Back' to the parent list view, I'd like the refresh button to show (un-hide) - but it remains hidden. Any idea how to make this work? This is my View: Ext.require(['Ext.data.Store', 'MyApp.model.StreamModel'], function() { Ext.define('MyApp.view.HomeView', { extend: 'Ext.navigation.View', xtype: 'homepanel', requires: [ 'Ext.dataview.List', ], config: { title: 'Home', iconCls: 'home', styleHtmlContent: true, navigationBar: { items: [ { xtype: 'button', iconMask: true, iconCls: 'refresh', align: 'left', action: 'refreshButton', id: 'refreshButtonId' } ] }, items: { title: 'My', xtype: 'list', itemTpl: [ '<div class="post">', ... '</div>' ].join(''), store: new Ext.data.Store({ model: 'MyApp.model.StreamModel', autoLoad: true, storeId: 'stream' }), } } }); }); and my Controller: Ext.define('MyApp.controller.SingleController', { extend: 'Ext.app.Controller', config: { refs: { stream: 'homepanel' }, control: { 'homepanel list': { itemtap: 'showPost' } } }, showPost: function(list, index, element, record) { this.getStream().push({ xtype: 'panel', html: [ '<div class="post">', '</div>' ].join(''), scrollable: 'vertical', styleHtmlContent: true, }); Ext.getCmp('refreshButtonId').hide(); } });

  • Trying to modify the text of a document onkeydown is inserting text incorrectly.

    - by Benny
    I have the following html: <html> <head> <script> function myKeyDown() { var myDiv = document.getElementById('myDiv'); myDiv.innerHTML = myDiv.innerHTML.replace(/(@[a-z0-9_]+)/gi, '<strong>$1</strong>'); } function init() { document.addEventListener('keydown', myKeyDown, false); document.designMode = "on"; } window.onload = init; </script> </head> <body> <div id="myDiv"> This is my variable name: @varname. If I type here things go wrong... </div> </body> </html> My goal is to do a kind of syntax highlighting on edit, to highlight variable names that begin with an @ symbol. However, when I edit the document's body, the function runs but the cursor is automatically shifted to the beginning of the body before the keystroke is performed. My hypothesis is that the keypress event is trying to insert the new character at a specified index, but when I run the replace function the indices get messed up so it defaults the character insertion point to the beginning. I'm using Firefox to test by the way. Any help would be appreciated. Thanks, B.J.

  • jquery ui autocomplete does't close options menu if there is no focus when ajax returns

    - by Uri
    I'm using jquery ui autocomplete widget with ajax, and on noticed the following problem. Background: In order for the user to be able to focus on the autocomplete and get the options without typing anything, I use the focus event: autoComp.focus(function() { $(this).autocomplete("search", "");} However this produces the following effect: when the user clicks, an ajax request is being sent. While waiting for the response, the user then clicks elsewhere and the autocomplete is blurred. But as soon as the response returns, the options menu pops out, even though the autocomplete has no focus. In order to make it go away the user has to click once inside, and again outside the autocomplete, which is a bit annoying. any ideas how I prevent this? EDIT: I solved this in a very ugly way by building another mediator function that knows the element's ID, and this function calls the ajax function with the ID, which on success check the focus of the element, and returns null if it's not focused. It's pretty ugly and I'm still looking for alternatives. EDIT#2: Tried to do as Wlliam suggested, still doesn't work.. the xhr is undefined when blurring. Some kind of a problem with the this keyword, maybe it has different meanings if I write the getTags function outside of the autocomplete? this.autocomplete = $('.tab#'+this.id+' #tags').autocomplete({ minLength: 0, autoFocus: true, source: getTags, select: function(e, obj) { tab_id = $(this).parents('.tab').attr('id'); tabs[tab_id].addTag(obj.item.label, obj.item.id, false); $(this).blur(); // This is done so that the options menu won't pop up again. return false; // This is done so that the value will not stay in the input box after selection. }, open: function() {}, close: function() {} }); $('.tab#'+this.id+' #tags').focus(function() { $(this).autocomplete("search", ""); }); $('.tab#'+this.id+' #tags').blur(function() { console.log('blurring'); var xhr = $(this).data('xhr'); // This comes out undefined... :( if (xhr) { xhr.abort(); }; $(this).removeClass('ui-autocomplete-loading'); }); and this is the getTags function copied to the source keyword: function getTags(request, response) { console.log('Getting tags.'); $(this).data('xhr', $.ajax({ url: '/rpc', dataType: 'json', data: { action: 'GetLabels', arg0: JSON.stringify(request.term) }, success: function(data) { console.log('Tags arrived:'); tags = []; for (i in data) { a = {} a.id = data[i]['key']; a.label = data[i]['name']; tags.push(a); } response(tags); } })); console.log($(this).data('xhr')); }

  • Designing code for a duo Website + AIR desktop App

    - by faB
    I want to use AIR to create an OFFLINE version of a "webapp" kind of website (lots of ajax, front end code). Haven't been much further than the HelloWorld example, I keep wondering: how do you design your code, to maximize code reuse between the website (say in php or Java or .Net), and the AIR app ? Can you actually re-use 100% of the front end code, provided that it is designed to account for the AIR app ? How would you go about doing that ? For example, the website makes many Ajax calls which have latency, and uses listeners. The AIR app doesn't need listeners it could run database requests synchronously, and it doesn't need to run ajax calls right? Would you write an abstraction layer for that ? So that the same calls on the AIR app will not do a xmlhttp but instead implement the server-side code with AIR; and call the listener ? So you don't have to rewrite the front end code patterns ? Does this make sense ? It's really hard to search on Google. I'm thinking there must be a good article somewhere of somebody who went through and perhaps a framework to do that ?

  • 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.

  • Eta/Eta-squared routines in R

    - by aL3xa
    Apart from graphical estimation of linearity (gaze-at-scatterplot method), which is utilized before applying some technique from GLM family, there are several ways to do this estimation arithmetically (i.e. without graphs). Right now, I'll focus on Fisher's eta-squared - correlation ratio: arithmetically, it's equal to squared Pearson's r (coef. of determination: R2) if relationship between two variables is linear. Hence, you can compare values of eta and r and make an assessment about type of relation (linear or not). It provides an information about percent of variance in the dependent variable explained (linearly or not) by the independent variable. Therefore, you can apply it when linearity assumptions are not met. Simply stated: is there a routine for eta/eta-squared in R?

  • jQuery Text to Link Script?

    - by Elijah Manor
    Does anyone know of a script that can select all text references to URLs and automatically replace them with anchor tags pointing to those locations? For example: http://www.google.com would automatically turn into <a href="http://www.google.com">http://www.google.com</a> Note: I am wanting this because I don't want to go through all my content and wrap them with anchor tags.

  • getComputedStyle text-decoration inherit

    getComputedStyle fails to get text-decoration property inherited, but can get font-size. Failed in Firefox 25 and GoogleChrome 30.

  • transition of x-axis results in overflow

    - by peter
    First of all, no: this question is not about the (yet) ugly transition of the lines (I might open another one for that, though..). I'm displaying data in line charts and the user can select the time horizon. The x-axis then correspondingly transitions so as to fit to the changed time horizon. In attached image, e.g., the time horizon was 1 week and then I switched to 4 weeks. The number of ticks on the x-axis increases from 7 to 28, correspondingly. Question: How can I prevent the x-axis animation to display outside the svg container? As you can see, the additional dates fly in from the left and they are being animated far far outside the container. Any ideas? Right now, the transition works probably in the most simple way it could: // format for x-axis var xAxis = d3.svg.axis() .scale(x) .orient("bottom") .tickFormat(d3.time.format("%d.%m")) .ticks(d3.time.days, 1) .tickSubdivide(0); // Update x-axis svg.select(".x") .transition() .duration(500) .call(xAxis);

  • How to catch GMail auto-refresh

    - by nameanyone
    I wrote a userscript to highlight the current row in GMail (indicated by the arrow). Unfortunately the highlight will only stay until GMail Inbox is auto-refreshed, which happens quite often. Is there a way to catch that event so I could reapply the highlighting? I don't want to do it on timeout. There is another userscript that does that and it loads up CPU.

  • 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.

  • 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.
