  • Syncronise Server Seconds with JS Clients

    - by imperium2335
    I would like to drive a setTimeout loop based on the time of the server, seconds only. So when the seconds on the server is 30, some function is run on all clients. It is vital that they do not become totally out of sync with the server, as there will be a CRON job running on the server every, say, 45 seconds which is important to the system functioning correctly. It is ok if a client is out by a few seconds with the server, client do not need to be synced to each other. I am using Jquery library. Hope this makes sense!

  • Apache Cordova (Phonegap): is jsop needed for cross-site scripting?

    - by DEX
    I've just started using Apache Cordova. I have an library that makes calls (via ajax) to a soap server. When I run these on my local machine in chrome, I get cross site scripting errors when trying to make calls to the service. When I run the same exact code using the Cordova browser in the iOS emulator, the scripts seem to hit the server fine and the response data is received properly. So my question is how is the Cordova browser able to make these requests without cross-site scripting permissions & JSONP ? One thing I noticed is that when the request is sent from iOS, there is no "Origin" header. Is this allowing the Cordova browser to stealthily circumvent cross-site scripting requirements? Is it possible that the node.js server on the device (I believe this is how Cordova works) is manipulating the headers to allow this? I'd like to avoid enabling cross-site scripting on my site so I think this "feature" is nice, but I'm wondering if it's a security hole as well. Anyone have experience with this?

  • Passing function-specific variables

    - by Simon Carlson
    Say I got two functions that looks like this: function main(Index) { doStuff(); } function doStuff() { if(Index == 1) { document.write("Hello world!") } } And some HTML: <input type="button" value="Click me" onclick="main(1)" /> I realize this is a very stupid way to use function-specific variables and such, but it's just out of curiosity. So is it possible to pass the variable Index from the main function to the doStuff function?

  • Reading data from a MySQL database into a HTML Table?

    - by Michael McKay
    So i am working on a project and need some advice. I have a MySQL database that stores events, i know how to code this functionality in PHP but im just stuck of a few specifics. As the project that I am creating is a timetable, the most important attributes are the day of the event, starting time and finishing time. Once i have read this data from the MYSQL database using my PHP script, how do i go about inserting these events in to a html timetable? Lets say i have record like below in my events table: Event ID = 01 Event Day = Monday Event Start = 12:00 Event End = 14:00 How would I then put that into a html table, bearing in mind that i may have mutiple events for a day?

  • Warn user when new data is inserted on database

    - by João Menighin
    I don't know how to search about this so I'm kinda lost (the two topics I saw here were closed). I have a news website and I want to warn the user when a new data is inserted on the database. I want to do that like here on StackOverflow where we are warned without reloading the page or like in facebook where you are warned about new messages/notifications without reloading. Which is the best way to do that? Is it some kind of listener with a timeout that is constantly checking the database? It doesn't sounds efficient... Thanks in advance.

  • Problem accessing private variables in jQuery like chainable design pattern

    - by novogeek
    Hi folks, I'm trying to create my custom toolbox which imitates jQuery's design pattern. Basically, the idea is somewhat derived from this post: http://stackoverflow.com/questions/2061501/jquery-plugin-design-pattern-common-practice-for-dealing-with-private-function (Check the answer given by "David"). So here is my toolbox function: (function(window){ var mySpace=function(){ return new PrivateSpace(); } var PrivateSpace=function(){ var testCache={}; }; PrivateSpace.prototype={ init:function(){ console.log('init this:', this); return this; }, ajax:function(){ console.log('make ajax calls here'); return this; }, cache:function(key,selector){ console.log('cache selectors here'); testCache[key]=selector; console.log('cached selector: ',testCache); return this; } } window.hmis=window.m$=mySpace(); })(window) Now, if I execute this function like: console.log(m$.cache('firstname','#FirstNameTextbox')); I get an error 'testCache' is not defined. I'm not able to access the variable "testCache" inside my cache function of the prototype. How should I access it? Basically, what I want to do is, I want to cache all my jQuery selectors into an object and use this object in the future.

  • jQuery.Form wont submit

    - by kim
    Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

  • multiple ajax request to action in asp.net mvc

    - by persian Dev
    I am developing an asp.net mvc application and have ajax calls on my page. Here is a form which I load by ajax call to page : The form is located in a partial view <div id="CreateCultureArea"> <% using (Ajax.BeginForm("CreateCulture", "Admin", new AjaxOptions() { OnSuccess = "handleCreateCulture" })) { %> ..... <% } %> </div> The following script is located in a view $('.CreateCulture').live('click', function (e) { e.preventDefault(); var idval = this.id; $.ajax({ url: "/Admin/CreateCulture", dataType: 'html', data: { id: idval }, success: function (mydata) { $("#CultureContentArea").empty(); $("#CultureContentArea").empty().hide().append(mydata).fadeIn(2000); $("form").removeData("validator"); $("form").removeData("unobtrusiveValidation"); $.validator.unobtrusive.parse("form"); }, type: "GET" }); return false; }) </script> When users click on a link with CreateCulture class, the form is loaded to page. But as I saw the requests in firebug, it calls the action multiple times. I read similar posts like mine on stackoverflow.com and most of them suggested removing repetitive "jquery.unobtrusive-ajax.min.js" calss in page, but as I saw the output page I only see on link to the "jquery.unobtrusive-ajax.min.js" script.

  • jQuery selector .not() NOT working

    - by Niko M.
    I've built a jQuery selector for a function which looks like this: $('html').not('.table-main tr[selected]').mousedown( function( e ) { But somehow it is not filtering at all and i do not quite understand why. Even if i just leave ('.table-main') for the selector i still trigger the function when clicking into the table... What is wrong with that? Using document or 'body' instead of 'html' does not help, as document is not triggering at all with .not() and 'body' results in the same.

  • Call an anonymous function defined in a setInterval

    - by Tominator
    Hi, I've made this code: window.setInterval(function(){ var a = doStuff(); var b = a + 5; }, 60000) The actual contents of the anonymous function is of course just for this small example as it doesn't matter. What really happens is a bunch of variables get created in the scope of the function itself, because I don't need/want to pollute the global space. But as you all know, the doStuff() function won't be called until 60 seconds in the page. I would also like to call the function right now, as soon as the page is loaded, and from then on every 60 seconds too. Is it somehow possible to call the function without copy/pasting the inside code to right after the setInterval() line? As I said, I don't want to pollute the global space with useless variables that aren't needed outside the function.

  • ASP.NET MVC routing and paths is js files

    - by HiveHicks
    Hello, we're facing a problem now. We have a pretty big page with a loooong inline script, which does all the work. We now want to obfuscate it and use it as a separate .js file. But the problem is that we have paths which are generated by Url helper (Url.Content()). So what is the best way to separate js file from the page and not using hard-coded path strings?

Edit: document.oncontextmenu = null does not work. P.S. I cannot have the reference of the listener function since I am not the owner of the site preventing the context menu.

  • jQuery version of YAHOO.lang (isUndefined, isNull, isString etc.)

    - by Chris S
    Does anyone know of a jQuery plugin that has 'helpers' or extensions like those found in the YAHOO.lang namespace? I have in mind functions such as: isNull isDefined isString isFunction I would also appreciate the same kind of thing for strings and arrays, such as Contains, StartsWith (I know these are easy to write, I'm just looking for a plugin that encompasses them all). It's not in the YAHOO.lang namespace but also form related extensions- determining a radiobox's value (from the one checked), a form element's type in a friendly name. Specifically a plugin with fluent API rather than selector based such as $("input[@type=radio][@checked]") Again I'm aware they're easy to implement but I don't want to reinvent the wheel.
