  • Flipping around a div using Javascript

    - by Isaac Copper
    Flip is a great JQuery plugin for flipping blocks, but it doesn't preserve the background while it animates the flip. For example, I have this pretty background, here, before I flip. While flipping, it gets ugly: here. Is there a way I can flip this div nicely, keeping the pretty background I have, and maybe even achieve a smoother animation than I can get with Flip? If I need to dive into this headfirst and code my own function for flipping a div, that's also doable, and I'd really appreciate some pointer there, if that's what I must do. Thanks so much!

  • javascript to determine if page on remote domain has changed

    - by uku
    Hi, I am trying to find a client-side way to determine if a page on a remote domain has changed. I can't load the page in an iframe and examine its contents due to same origin policy. So I tried using .getResponseHeader("Content-Length") and .getResponseHeader("Last-Modified") but apparently these are also restricted by SOP even though FireBug shows Content-Length in the console. Is there a way to do this? I just need a way to know if the page has changed. Thx

  • Global javascript variable not accessible in jquery change event

    - by Dan
    I have to be missing something simple, but I'm really not sure what. I'm not a JS veteran, so this may be an easy answer - sure hope so :). I have a button that, when clicked, gets JSON data. When a drop-down is changed, I check to see if there is data, if there is, I want to clear it out as the drop-down indicates what data to retrieve when the button is clicked The Code: var selected, $locDialog; var locations = []; $(function() { // Save the selected Name selected = $("#selected option:selected").val(); // Setup Dialog for Locations $locDialog = $('#location-dialog').dialog({ autoOpen: false }); // If user changes the selected // 1. Prompt for confirmation // 2. If users confirms, clear data $('#selected').change(function() { if (locations) { var confirmed = confirm("Oh Rly?"); if (confirmed) { // Clear data var locations; } } }); // When user clicks "Location" Button.. $('.loc-select button').click(function() { if (!locations) { $.getJSON("/Controller/JSONAction", { selectedId: selected, pageNum: 1, pageSize: 100 }, function(data) { locations = data; $.each(locations, function(index, loc) { var $tr = $('<tr/>') .append($('<td/>') .append('<input type="checkbox" name="TEST-'+index+'" value="'+loc.Id+'"/>')) .append('<td>' + loc.Name + '</td>'); $("#location-dialog table tbody").append($tr); }); }); } $locDialog.dialog('open'); return false; }); }); Here's the thing, Inside the .click(...) callback, I can see locations is []. Now, when I am in the .change(...) callback, I see locations is undefined. Any help/insight, as always, is appreciated!

  • Finding multiple values in a string Jquery / Javascript

    - by user257503
    I have a three strings of categories "SharePoint,Azure,IT"; "BizTalk,Finance"; "SharePoint,Finance"; I need to find a way to check if a string contains for example "SharePoint" and "IT", or "BizTalk" and "Finance". The tests are individual strings themselces. How would i loop through all the category strings (1 - 3) and only return the ones which have ALL instances of the souce. i have tried the following function doesExist(source, filterArray) { var substr = filterArray.split(" "); jQuery.each(substr, function() { var filterTest = this; if(source.indexOf(filterTest) != -1 ) { alert("true"); return true; }else { alert("false"); return false; } }); } with little success...the code above checks one at a time rather than both so the results returned are incorrect. Any help would be great. Thanks Chris UPDATE: here is a link to a work in progress version..http://www.invisiblewebdesign.co.uk/temp/filter/#

  • How much does Javascript garbage collection affect performance?

    - by Long Ouyang
    I'm writing a bunch of scripts that present images serially (e.g. 1 per second) and require the user to make either a keyboard or mouse response. I'm using closures to handle the timing of image presentation and user input. This causes garbage collection to happen pretty frequently and I'm wondering if that will affect the performance (viz. timing of image presentation).

  • Javascript Prototype Best Practice Event Handlers

    - by nahum
    Hi this question is more a consulting of best practice, Sometimes when I'm building a complete ajax application I usually add elements dynamically for example. When you'r adding a list of items, I do something like: var template = new Template("<li id='list#{id}'>#{value}</li>"); var arrayTemplate = []; arrayOfItem.each(function(item, index){ arrayTemplate.push(template.evaluate( id : index, value : item)) }); after this two options add the list via "update" or "insert" ----- $("elementToUpdate").update("<ul>" + arrayTemplate.join("") + "</ul">); the question is how can I add the event handler without repeat the process of read the array, this is because if you try add a Event before the update or insert you will get an Error because the element isn't still on the DOM. so what I'm doing by now is after insert or update: arrayOfItem.each(function(item, index){ $("list" + index).observe("click", function(){ alert("I see the world"); }) }); so the question is exist a better way to doing this??????

  • Calling javascript function with arguments using JSNI

    - by jav_000
    I'm trying to integrate Mixpanel with GWT, but I have problems calling an event with a property and one value. My function to track an simple event (without values): public native void trackEvent(String eventName)/*-{ $wnd.mixpanel.track(eventName); }-*/; It works. But when I want to add some properties and values, it doesn't work properly: public native void trackComplexEvent(String eventName, String property, String value)/*-{ $wnd.mixpanel.track(eventName, {property:value}); }-*/; I have 2 problems with this: 1) Mixpanel says the property name is: "property"(yes, the name of the variable that I'm passing, not the value). 2) Mixpanel says the value is:undefined An example from mixpanel web is: mixpanel.track("Video Play", {"age": 13, "gender": "male"}); So, I guess the problem is I'm doing a wrong call or with wrong type of arguments.

  • how to set style through javascript in IE immediately

    - by rezna
    Hi, recently I've encountered a problem with IE. I have a function function() { ShowProgress(); DoSomeWork(); HideProgress(); } where ShowProgress and HideProgress just manipulate the 'display' CSS style using jQuery's css() method. In FF everything is OK, and at the same time I change the display property to block, progress-bar appears. But not in IE. In IE the style is applied, once I leave the function. Which means it's never shown, because at the end of the function I simply hide it. (if I remove the HideProgress line, the progress-bar appears right after finishing executing the function (more precisely, immediately when the calling functions ends - and so there's nothing else going on in IE)). Has anybody encountered this behavior? Is there a way to get IE to apply the style immediately? I've prepared a solution but it would take me some time to implement it. My DoSomeWork() method is doing some AJAX calls, and these are right now synchronous. I assume that making them asynchronous will kind of solve the problem, but I have to redesign the code a bit, so finding a solution just for applying the style immediately would much simplier. Thanks rezna

  • Catching "NullPointerExceptions" in JavaScript

    - by Lenni
    I'm writing quite a bit of code in Prototype.js which returns null if a DOM-id wasn't found. $("someId").show(); If someId doesn't exist, a method will be called on null, which halts the entire program, in effect disabling all JS effects after the error. I could just check for null before executing such a statement, but this is getting tiring. I would like to catch an exception but I'm not sure which one its is. MDC lists the following ECMA Script error types: * Error * EvalError * RangeError * ReferenceError * SyntaxError * TypeError * URIError * DOMException * EventException * RangeException Also, do browsers have a unified way of dealing with a method call on null?

  • regex not working "within" javascript string

    - by Tim
    I'm trying to replace all mentions of [b] in a text string and replace it with <b>. The problem with what I'm using below this that it's replace every [b] on the page, and I only want it to change the [b]'s within the text string ("text") that I'm sending in. Taking out the 'g' for global in the regex doesn't work very well because it then doesn't replace them all... text = text.replace(new RegExp('(^|\\s|>)\\[b](\\S.*?\\S)\\[/b]($|\\s|<)', 'gim') , '$1<strong>$2</strong>$3'); any ideas? Thanks

  • jquery / javascript for a user to select 1 of n images

    - by TesterTurnedDeveloper
    I want to display a few images (probably 5 max) and have a user click to select one. First thing I tried was radio buttons and putting the images inside labels. <input type="radio" name="BackgroundId" id="BackgroundId" value="1" /> <label for="BackgroundId"><img src="../../Content/images/thumb_1.jpg" /></label> Firefox will select the radio button when the user clicks the image, but IE doesn't. Is there a jquery plugin that will make the images clickable? Fancy-form looks like something I could use, but it isn't jquery and I've already got jquery in my project. Or can someone point me to a better way of selecting a single image?

  • Javascript pass reference by value

    - by Carlos R. Batista
    Im having this weird reference issue when im trying to get a JSON file through query: var themeData; $.getJSON("json/sample.js", function(data) { themeData = data.theme; console.log(themeData.sample[0].description); }); console.log(themeData.sample[0].description); The first console.log works, the second doesnt. Im guessing because "data" already expired by the time the script gets there and themeData is just a mere pointer to "data". Is there a ways I can make sure themeData gets a duplicate of "data" and not just a pointer to it?

  • changing css properties via javascript

    - by tic
    I need a function to change the appearance of some elements in my html page "on the fly", but I am not able to do. The problem is that I cannot use a command like document.write ('body {background-color: #cccccc;}'); because I need to make the changes effective when the page is already loaded, using a link like <a onmouseclick="Clicker(1)" href="#">clic</a> and I cannot use a command like document.body.style.background='#cccccc'; because I do not know if it can be applied to other not so easy cases, because I need to change the appearance of elements such as td.myclass or sibling elements such as th[scope=col]+th[scope=col]+th[scope=col]. How can I do it? Thanks!

  • jquery javascript module architecture on a website

    - by stephan
    I want to write a module on one html site - I will never leave the site I think about two possible concurrent basic approaches: We go into the module by use only a specific function (with specific params - everything which will happen, happen there - logic, exception handling etc) We go in by using one handler-fct, which manages some kind of action & a dataArray (depending on the action also fcts will be called - but not directly maybe for exception handling) So what you prefer?!
