  • Problem with accessing in DOM with jQuery

    - by Tristan
    Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

  • jquery ui autcomplete does not disapper with no result

    - by mike
    Hi, I'm using jquery ui autocomplete with the following code: $('#company').autocomplete({ source: function(request, response) { var company_name = $('#company').val(); $.ajax({ type: 'post', url: 'http://new.admin.localhost/client/helper/lookup_company_name', cache: false, data: { company : company_name }, dataType: 'json', success: function(data) { //alert(data); response($.map(data.companies, function(item) { return { label: item.company, value: item.company } })) } }) }, minLength: 2, }); This works as expected... The problem is, if the first few chars match something and then you enter a char that should "break" any match, it just keeps the drop down in place with the results for the last matched char... make sense? Would this be something I needed to change in the script that returns the data or something in the jquery? thanks!

  • Better alternatives to know whether a control is valid in javascript?

    - by Anthony
    I want to know whether a control is valid or not in javascript. Is there a direct client side API available in Asp.Net which can tell me whether a control is valid or not? Eg. If I have 2 validators attached to a textbox, I need a function that can tell me whether the textbox is valid or not. If even 1 validator is not valid then it should return false. I can't seem to find a function that can give me this. Here is a little helper that I wrote which does the job but is inefficient: function isControlValid(control) { for (i = 0; i < Page_Validators.length; i++) { var validator = Page_Validators[i]; var controlId = validator.controltovalidate; if ($(control).attr('id') == controlId && validator.isvalid == false) { return false; } } return true; } Anybody has any better alternatives?

  • Carrying scope of "this" into inner functions

    - by Matrym
    How can I extend the scope of this inward? I thought reassigning a higher scoped variable would do the trick... what am I doing wrong? http://jsfiddle.net/8bqXM/ function Player(configs) { this.opts = { playerID: "cSurf" }; configs = $.extend(this.opts, configs); var the = this; this.init = function(){ var $player = $("#" + the.configs.playerID); alert($player.attr("id")); } } var cSurf = new Player(); $(document).ready(function(){ cSurf.init(); });

  • jquery draggable accept: classpath

    - by heldopslippers
    Hi guys.. I have problems with the following bit of javascript/jquery code: this.droppable = function(){ $('.imageWindow .body .item').draggable(); $('.groupWindow .body .item').droppable({ accept: $(".imageWindow .body .item"), over: function(event, ui) { alert("this is valid!"); }, drop: function(){ alert('dropped'); } }); } As you maybe know it is not possible to pass the following in the accept option: $(".imageWindow .body .item") But what is possible ? I want to pass a "class path" as an accept option ! It is probably a simple answer but i can't figure it out. Of course i could do: accept: ".item" But because "groupWindow .body .item" is a sortable it would also accept himself! Thanxs if you can help me!

  • A good way to look back arbitrary number of items in the Array.Fold in F#

    - by tk
    In the folder function of the Array.Fold operation, i want to look back arbitrary number of items. The only way i can figure out is like this. let aFolder (dataArray, curIdx, result) (dataItem) = let N = numItemsToLookBack(result, dataItem) let recentNitems = dataArray.[curIdx - n .. curIdx - 1] let result = aCalc(result, dataItem, recentNitems ) dataArray, curIdx + 1, result myDataArray | Array.fold aFolder (myDataArray, 0, initResult) As you can see, I passed the whole dataArray and index to the folder function to get the "recentNitems". But this way allows the folder function to access not only preceding data, but also the following data. Is there a better (or more functional) way?

  • should variable be released or not? iphone-sdk

    - by psebos
    Hi, I have the following piece of code from a book. There is this function loadPrefs where the NSString *userTimeZone is being released before the end of the function. Why? The string was not created with alloc and I assume that the stringForKey function returns an autoreleased NSString. Is this an error or am I missing something? Is it an error in the book? (I new into objective-C) In the documentation for stringForKey the only thing it mentions is: Special Considerations The returned string is immutable, even if the value you originally set was a mutable string. The code: - (void) loadPrefs { timeZoneName = DefaultTimeZonePref; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSString *userTimeZone = [defaults stringForKey: TimeZonePrefKey]; if (userTimeZone != NULL) timeZoneName = userTimeZone; [userTimeZone release]; show24Hour = [defaults boolForKey:TwentyFourHourPrefKey]; } Thanks!!!!

  • C - memset segfault for statically allocated char array

    - by user1327031
    I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

  • Two buttons in a form, Both called

  • Restricting numeric input javascript problem

Here's the code below: (function(){ if(window.addEventListener) window.addEventListener("load",init,false); else if(window.attachEvent) window.attachEvent("onload",init); function init() { var keytest = document.getElementById("keytest"); function numericinput(event) { var e = event || window.event; var key = e.charcode || e.keyCode; var regex =/^\d+\.?\d{4}$/; key = String.fromCharCode(key); if (!regex.test(key)) { alert("something"); //if(e.preventDefault) e.preventDefault(); //if(e.returnValue) e.returnValue = false; //return false; } else { //return true; alert("something else"); } } if(keytest.addEventListener) keytest.addEventListener("keypress",numericinput,false); else { keytest.onkeypress = numericinput(); } } })();

  • How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

    - by Kendrick Ledet
    Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

  • MVC partial page update

    - by GB
    Hello, I have an MVC project where I have a form with fields a user can enter and save. On that same page I have a table which shows a brief listing of information that the user just saved. The problem I am having is trying to update only the table after a save and not an entire page refresh. Is this possible in jquery or MVC? If so does anyone have an example. Here is what the action in the controller looks like: public ActionResult RefreshList() { string _employeeID = Request.QueryString["empIDSearch"]; this.ViewData["coursehistorylist"] = _service.ListCoursesByEmpID(_employeeID); return View("CourseHistoryList"); } The function in the view: (and this is where I'm confused on how to update only the table) $.ajax({ url: "/Home/RefreshList", type: "POST", success: function(result) { alert("got here"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.status + " " + thrownError + " " + ajaxOptions); } }); Thanks.

  • Is there any injection vunerability in the body of an email?

    - by Brett
    Hey guys..... AFAIK there is only a vulnerability within the HEADERS of an email when using user data correct? I am using the below function to sanitize my data, however I have some textarea fields on the page & hence these may contain linebreaks.. so was wondering if that user data is only going to be put in the body of the email, can it not bother with being sanitized - apart from stripping html of course? Here is the function: function is_injected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if (preg_match($inject,$str)) { return true; } else { return false; } } As a side note, surprised there wasn't currently a tag for mail-injection / email-injection. Thanks!

  • Adding an integer onto an array

    - by Ohmnastrum
    I'm trying to add random numbers onto the end of this array when ever I call this function. I've narrowed it down to just this so far. when ever I check to see if anything is in the array it says 0. So now i'm quite stumped. I'm thinking that MutableArray releases the contents of it before I ever get to use them. problem is I don't know what to use. A button calls the function and pretty much everything else is taken care of its just this portion inside the function. NSMutableArray * choices; -(void) doSomething { int r = arc4random() % 4; //The problem... [choices addObject:[NSNumber numberWithInt:r]]; int anInt = [[choices objectAtIndex:1] integerValue]; NSLog(@"%d", anInt); //I'm getting nothing no matter what I do. //some type of loop that goes through the array and displays each element //after it gets added }
