  • Best multi-platform mobile development tool, or use iPhone tools?

    - by Jesse Millikan
    I may be building a mobile app for a client soon. Their primary focus is the iPhone, but my boss would like to be able to target multiple platforms if it's feasible. The app will probably be a large but technically simple business application backed by a web service. So, here's the question as I see it: What is currently the strongest cross-platform mobile development tool that supports iOS? Would you choose it over native development tools? If you choose native, contrast it with a cross-platform tool you've used. In addition, For a project of the type we're expecting, what's the level of effort for your chosen tool versus other tools? What's the actual level of support of the tool for other platforms and their unique look and feel, capabilities, etc.? How thorough is the documentation of the product? How well do you like the development experience itself, e.g. the language, tools, documentation? Is it something you would choose to do long-term? I'll put a bounty out unless I get fantastic answers.

  • Are there any significant advantages to using a native language for mobile app development?

    - by Karl Daniel
    Forgive me if this question has already been answered but I couldn't quite find the answer I was looking for. What I wanted to know was, is there any significant advantage to using a native language when developing and deploying apps to a mobile environment? The reason I ask is for a long while now I've been using Objective-C, Apple's native language for iOS, to build my apps. However I've been wondering whether or not there is any real benefit to doing this, over using a non-native language like JavaScript and then deploying it through a service like 'Phone Gap'? I do stress 'significant' advantages as native languages are always more likely to have the upper hand when it comes to speed and access to the latest APIs. However in general I don't see using a non-native language or a service like 'Phone Gap' causing and major slow down to my apps or restricting my development. Additionally having the ability to deploy to multiple services is also very handy indeed. This is why I put the question, are there any significant advantages to using a native language for mobile app development?

  • How do the performance characteristics of jQuery selectors differ from those of CSS selectors?

    - by Moss
    I came across Google's Page Speed add-on for Firebug yesterday. The page about using efficient CSS selectors said to not use overqualified selectors, i.e. use #foo instead of div#foo. I thought the latter would be faster but Google's saying otherwise, and who am I to go against that? So that got me wondering if the same applied to jQuery selectors. This page I found the link to on SO says I should use $("div#foo"), which is what I was doing all along, since I thought that things would speed up by limiting the selector to match div elements only. But is it really better than writing $("#foo") like Google's saying for CSS selectors, or do CSS versus jQuery element matching work in different ways and I should stick with $("div#foo")?

  • Legally Blind and need help creating a windows mobile 6.1 theme

    - by unknown (yahoo)
    Hello, I just bought an HTC Touch Pro2. I previously have used a MotoQ. On the Q, I managed to write XML code to change my color scheme (not just the bars, but the background color and font colors.) I cannot seem to find how to do this on the HTC. I will explain: I am legally blind and can only see my phone if the colors are reversed i.e. I need the background of all menus and such to be black and the font to be white. Can anyone help me? I am a desperate woman!!!!

  • What jquery code or plugin would I use to update the position of an element?

    - by Breadtruck
    I am using a jquery plugin from [ FilamentGroup ] called DateRangePicker. I have a simple form with two text inputs for the start and end date that I bind the DateRangePicker to using this $('input.tbDate').daterangepicker({ dateFormat: 'mm/dd/yy', earliestDate: new Date(minDate), latestDate: new Date(maxDate), datepickerOptions: { changeMonth: true, changeYear: true, minDate: new Date(minDate), maxDate: new Date(maxDate) } }); I have a collapsible table above this form that when shown, moves the form and the elements that the daterangepicker plugin is bound to, down lower on the page, but the daterangepicker appears to keep the position from when it was actually created. What code could I put in the daterangepicker's onShow Callback to update its position to be next to the element is was initially bound to? Or is there some specific jquery method or plugin that I could chain to the daterangepicker plugin so that it will update its position correctly. This would come in handy for some other plugins that I use that don't seem to keep their position relative to other elements correctly either.

  • OpenBSD pf 'match in all scrub (no-df)' causes HTTPS to be unreachable on mobile network

    - by Frank ter V.
    First of all: excuse me for my poor usage of the English language. For several years I'm experiencing problems with the 'match in all scrub (no-df)' rule in pf. I can't find out what's happening here. I'll try to be clear and simple. The pf.conf has been extremely shortened for this forum posting. Here is my pf.conf: set skip on lo0 match in all scrub (no-df) block all block in quick from urpf-failed pass in on em0 proto tcp from any to 213.125.xxx.xxx port 80 synproxy state pass in on em0 proto tcp from any to 213.125.xxx.xxx port 443 synproxy state pass out on em0 from 213.125.xxx.xxx to any modulate state HTTP and HTTPS are working fine. Until the moment a customer in France (Wanadoo DSL) couldn't view HTTPS pages! I blamed his provider and did no investigation on that problem. But then... I bought an Android Samsung Galaxy SII (Vodafone) to monitor my servers. Hours after I walked out of the telephone store: no HTTPS-connections on my server! I thought my servers were down, drove back to the office very fast. But they were up. I discovered that disabling the rule match in all scrub (no-df) solves the problem. Android phone (Vodafone NL) and Wanadoo DSL FR are now OK on HTTPS. But now I don't have any scrubbing anymore. This is not what I want. Does anyone here understand what is going on? I don't. Enabling scrubbing causes HTTPS webpages not to be loaded on SOME ISP's, but not all. In systat, I strangely DO see a state created and packets received from those ISP's... Still confused. I'm using OpenBSD 5.1/amd64 and OpenBSD 5.0/i386. I have two ISP's at my office (one DSL and one cable). Affects both. This can be reproduced quite easily. I hope someone has experience with this problem. Greetings, Frank

  • Is is possible to to have a depends on a jQuery remote validation?

    - by David Kethel
    I am using jQuery remote validation to check if the description is already being used. Description: { required: true, maxlength: 20, remote: function () { var newDescription = $("#txtDescription").val(); var dataInput = { geoFenceDescription: newDescription }; var r = { type: "POST", url: "/ATOMWebService.svc/DoesGeoFenceDescriptionExist", data: JSON.stringify(dataInput), contentType: "application/json; charset=utf-8", dataType: "json", dataFilter: function (data) { var x = (JSON.parse(data)).d; return JSON.stringify(!x); } }; return r; } }, The problem I have is that this remote validation occurs when the user has NOT modified the text box and comes back saying the description has been used because it found it self in the database. So is it possible to only run the remote validation if the text field is different to what was originally in it? I noticed the the jQuery required validation has a depends option, but I couldn't get it to work with the remote call.

  • jQuery onmouseover + onmouseout / hover on two different divs

    - by ahmet2106
    Hello everybody, I've got a Problem: Here a part of my HTML: <div id="div_1"> Here Hover </div> <div id="div_2"> Here content to show </div> And here a part of my jQuery Script: jQuery('#div_2').hide(); jQuery('#div_1').onmouseover(function() { jQuery('#div_2').fadeIn(); }).onmouseout(function(){ jQuery('#div_2').fadeOut(); }); The Problem: If i hover on the div_1, the div_2 is shown, if i hover out, the div_2 is hidden, but: If i hover first on div_1 and then go over div_2, the div_2 is hidden fast. I've tried this with jQuery.addClass(); after mouseout in div_1, but nothing is changing. I dont want do make the second div in the first div... Is there another way with jQuery? Thx Ahmet

  • How backward compatible are the HSDPA mobile networks

    - by Chris Kimpton
    Hi, I have got this Huawei wifi device, which has been unlocked for other networks. Works fine in UK on Vodafone (as well as 3). We are trying to get it to work with the Claro network in Jamaica. It connects and stays connected, but fails to get a 3g connection, just the slow EDGE one. Claro support say its because Claro currently does not support the 2100MHz frequency for 3G, which is what the device uses Does that sound correct? They say I need one that: Ensure however that these devices can use the 850MHz frequency. My understanding was that the device supports up to 2100, including their 850mhz... I am thinking that maybe the APN is incorrect, but I have set it to the only value I can find on the net, namely: internet.ideasclaro.com.jm Thanks in advance, Chris

  • Using jQuery for client side validation in MVC2 RTM

    - by tigermain
    Scott Gu's tutorial on Model validation gets us all set up with the MS client side validation using the following scripts: <script src="../../Scripts/jquery.validate.min.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> However I've seen various posts allowing us to utilise jQuery instead with the following code: <script src="https://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="https://ajax.microsoft.com/ajax/jQuery.Validate/1.6/jQuery.Validate.min.js" type="text/javascript"></script> <script src="<%= Url.Content("~/scripts/MicrosoftMvcJQueryValidation.js") %>" type="text/javascript"></script> However MicrosoftMvcJQueryValidation.js does not ship with the solution and from what I read it should be part of the Futures pack which is no longer available on CodePlex. I managed to find a version alongside jQuery 1.3.2 but it does not work. What is the forward going solution!?

  • Can jQuery animate() behave differently for specific elements within my selection?

    - by Sune Rasmussen
    I have a selection of elements in a jQuery object. I want to animate their font sizes, but as I have both the headlines and various paragraphs in the selection, they should be animated slightly differently, as the headlines should end up with a larger font size than the paragraphs. I already have this information stored in the jQuery data cache. I can do that. But, not unless I use several calls to the animate function, one for each specific, slightly different animation, perhaps using event triggering or setTimeout() calls. Of course I want to avoid this, as it's damn ugly and an odd way around. Much prettier if it could be done internally, within the animation ... Any help would be much appreciated.

  • jQuery Validate - Require at least one from group, plus additional items.

    - by Kevin Pullin
    I'm attempting to use 'jQuery Validate' on a form that requires an email address plus either all items of a shipping address completed or none at all. Using the sample provided by the solution to this question: jQuery Validate - “Either skip these fields, or fill at least X of them”, I have been able to successfully solve the validation of the address group. The problem, however, is that the logic for validating the email address field does not work. From debugging the Validate scripts, the "re-entrant" validation code triggered by calling 'fields.data('being_validated', true).valid();' in the linked example results in a reset of all previously validated errors (i.e. the email validation error is cleared). I have modified some existing samples, the first in which removes the offending line and the second with it included. Email Validation Working Email Validation Fails Any tips or suggestions on how to properly solve this or work around the failure?

  • Can jQuery UI's Sortable handle complex selectors for the items option?

    - by jverdi
    I have list items in an unordered list that when double clicked, can be edited in place via a wysiwyg editor. $('ul.mtm_section').sortable({ disabled: true, distance: 10, items: '> li:not(:has(form))' }); My goal is to prevent the list item from being sorted while it is being edited - aka once a form element has been swapped in place of the contents. Unfortunately my selector for items is not working. Is sortable able to handle complex selectors like these? If not, are there other clever means to disable some items from being sortable, perhaps a callback function? I would prefer to rely on this sortable option, as the wysiwyg plugin is deeply nested with jEditable and as far as I know does not open up any events for me to hook into. Using jQuery 1.4.2 and jQuery UI 1.8.1

  • Prototype and jQuery concatenation failure

    - by Corey Hart
    I found something strange when trying to concatenate prototype and jQuery. It seems as though when concatenated, the $ jquery reference doesn't get overwritten by prototype. I've built two test cases to single this out, and it's failing in Chrome8 and FF 3.6. Test Case 1 - Without Concatenation jQuery and Prototype are loaded separately with different script tags. jQuery is loaded first, Prototype second. Test Case 2 - With Concatenation jQuery and Prototype are concatenated into a single file, and loaded with a single script tag. jQuery is first in the script, and prototype is added second. These should act identically, but the second test is throwing errors because the $ function in prototype doesn't overwrite the $ jquery reference. Did I set these up wrong, or are browsers rendering javascript differently when it's all in the same file?

  • How can I programmatically drop a Windows Mobile GPRS Connection?

    - by Rodriguez
    Hello, is there a way to explicitly close a GPRS connection? I'm setting up a connection with ConnectionManager and I've set the cache time to 10 seconds. Anyway after releasing it, the connection is still on, forever, alas I cannot use the registry key "gprs_by_if_device_off". I'm not using C# but plain C++. My idea is to simulate the activity of the windows button "disconnect data connection", but I really cannot understand what it does under the curtain. Thanx.

  • Changing the title of jQuery-UI dialog-box with in another dialog-box's function...

    - by Brian Ojeda
    Why doesn't doesn't the second jQuery-UI dialog box title change when popped. The first dialog box I change the title of the box with using the following .attr("title", "Confirm") -- it change the title of the first box to 'Confirm', like it should have. Now when the second box pops up it should change the title to 'Message' since did the same thing for the second box -- .attr("title", "Message"). Right? But it doesnt. It keep the title from before. However, the message change like it should have. I have tested in IE8, Chrome, and FF3.6. <div id="dialog-confirm" title=""></div> <-- This is the html before jQuery functions. Javascript / jQuery $('#userDelete').click(function() { $(function() { var dialogIcon = "<span class=\"ui-icon ui-icon-alert\"></span>"; var dialogMessage = dialogIcon + "Are you sure you want to delete?"; $("#dialog-confirm").attr("title", "Confirm").html(dialogMessage).dialog({ resizable: false, height: 125, width: 300, modal: true, buttons: { 'Delete': function() { $(this).dialog('close'); $.post('user_ajax.php', {action: 'delete', aId: $('[name=aId]').val() }, function(data) { if(data.success){ var dialogIcon = "<span class=\"ui-icon ui-icon-info\"></span>"; var dialogMessage = dialogIcon + data.message; $('#dialog-confirm').attr("title", "Message"); $('#dialog-confirm').html(dialogMessage); $('#dialog-confirm').dialog({ resizable: false, height: 125, width: 300, modal: true, buttons: { 'Okay': function() { $(this).dialog('close'); var url = $_httpaddress + "admin/index.php" $(location).attr('href',url); } // End of Okay Button Function } //--- End of Dialog Button Script });//--- End of Dialog Function } else { $_messageConsole.slideDown(); $_messageConsole.html(data.message); } }, 'json'); }, //--- End of Delete Button Function 'Cancel': function() { $(this).dialog('close'); } //--- End of Cancel Button Function } //--- End of Dialog Button Script }); //--- End of Dialog Script }); //--- End of Dialog Function return false; }); Thank you for you assistant, if you choose to help.

  • Google CDN not gzipping jquery

    - by thermal7
    If I navigate here: http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js I download 70k using Firefox 3.6.3 and I can confirm it is sending Accept-Encoding: gzip. If I use the Microsoft one: http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js I download 30k (and it comes through as Content-Encoding: gzip) I am also experiencing this when using jquery 1.4.2 in regular sites eg jquery.com. Funily enough, stack overflow which references jquery 1.3.2 on the google cdn, is coming through gzipped. Why is this happening? Is it some kind of issue with google or am I missing something? I live in Melbourne, Australia.

I came across this code in the JQuery documentation (function($sub) { $sub // a subclass of jQuery $sub === jQuery; //= false $sub.fn.myCustomMethod = function(){ return 'just for me'; } $sub(document).ready(function() { $sub('body').myCustomMethod(); //= 'just for me' }); })(jQuery.subclass()); Questions: Why is (function surrounded by () ? What does this mean (jQuery.subclass()); ? Is this a JQuery thing or part of regular javascript? Thanks
