  • Having trouble parsing XML with jQuery

    - by Jack
    Hi Guys, I'm trying to parse some XML data using jQuery, and as it stands I have extracted the 'ID' attribute of the required nodes and stored them in an array, and now I want to run a loop for each array member and eventually grab more attributes from the notes specific to each ID. The problem currently is that once I get to the 'for' loop, it isn't looping, and I think I may have written the xml path data incorrectly. It runs once and I recieve the 'alert(arrayIds.length);' only once, and it only loops the correct amount of times if I remove the subsequent xml path code. Here is my function: var arrayIds = new Array(); $(document).ready(function(){ $.ajax({ type: "GET", url: "question.xml", dataType: "xml", success: function(xml) { $(xml).find("C").each(function(){ $("#attr2").append($(this).attr('ID') + "<br />"); arrayIds.push($(this).attr('ID')); }); for (i=0; i<arrayIds.length; i++) { alert(arrayIds.length); $(xml).find("C[ID='arrayIds[i]']").(function(){ // pass values alert('test'); }); } } }); }); Any ideas?

  • Passing jquery JSON from Codeigniter controller to view

    - by dede
    I've been struggling to make it work, but cannot pass the inserted data from the controler to the view in CI using JSON. The input value from the form is successfully inserted into the database, but cannot make it appear in the view. This is my view file ajax_view.php: <script type="text/javascript" src="<?php echo base_url(); ?>js/jquery-1.4.2.min.js"></script> $(document).ready(function(){ $("#submit").click(function(){ var inp = $('#inp').val(); $.post("ajax/ajax_input", { 'send' : inp }, function(data){ alert(data.input_text); }, "json"); }); }); </script> </head> <body> <form id="form1" method="post" action=""> <label for="inp">Text</label> <input type="text" name="inp" id="inp" /> <label for="submit"></label> <input type="submit" name="submit" id="submit" value="Submit" /> And this is the ajax_input method of the ajax.php controller: <?php // Initializing controller ..... // ............................. //ajax method function ajax_input(){ $var_1 = trim($this->input->post('send')); $array = array('input_text' => $var_1); echo json_encode($array); $this->db->insert('ajax',$array); } Trying to debug it with Firebug, it gives me that data.input_text is empty. What am I doing wrong? EDIT: I'm using XAMPP on Win, so is it posible that json configuration is the problem?

  • Google maps KM bounds box reapplying itself on map zoom

    - by creminsn
    I have a map in which I apply a custom overlay using KMbox overlay to signify where I think the users general point of interest lies. What I want is to display this map to the user and allow them to click on the map to give me an exact location match of their POI. This all works fine except for when the user clicks on the map and changes the zoom of the map. Here's my code to add the marker to the map. function addMarker(location) { if(KmOverlay) { KmOverlay.remove(); } if(last_marker) { last_marker.setMap(null); } marker = new google.maps.Marker({ position: location, map: map }); // Keep track for future unsetting... last_marker = marker; } And to show the map I have this function. function show_map(lt, ln, zoom, controls, marker) { var ltln = new google.maps.LatLng(lt, ln); var vars = { zoom: zoom, center: ltln, mapTypeId: google.maps.MapTypeId.ROADMAP, navigationControl: controls, navigationControlOptions: {style: google.maps.NavigationControlStyle.ZOOM_PAN} , mapTypeControl: false, scaleControl: false, scrollwheel: false }; map = new google.maps.Map(document.getElementById("map_canvas"), vars); KmOverlay = new KmBox(map, new google.maps.LatLng(lat, lon), KmOpts); var totalBounds = new google.maps.LatLngBounds(); totalBounds.union(KmOverlay.getBounds()); google.maps.event.addListener(map, 'click', function(event) { addMarker(event.latLng); }); } I have a working example at the following link here

  • XMLHttpRequest() and outputting csv file

    - by sjw
    Initially, I developed a javascript function to use window.open to post contents of a form to a new window which simply opened the new window and initiated a csv file download. Now on reflection, I find the opening of the window superfluous and am trying to just execute a XMLHttpRequest() to download the csv. I am not getting what I want and I'm not 100% sure that I can so I thought I'd ask here for some assistance. When a form is submitted, I want to take all the form values and post them to another page which builds an SQL string and builds a csv based on the contents. (This I can do and works fine with XMLHttpRequest() as seen below) var xhReq = new XMLHttpRequest(); var parameters = ""; for ( i=0; i<formObj.elements.length; i++ ) { parameters += formObj.elements[i].name + "=" + encodeURI( formObj.elements[i].value ) + "&"; } xhReq.open("POST", outputLocation, false); xhReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xhReq.setRequestHeader("Content-length", parameters.length); xhReq.setRequestHeader("Connection", "close"); xhReq.send(parameters); document.write(xhReq.responseText); The code above calls the page ok, builds the csv ok, but it outputs the contents into the current browser window instead of initiating a csv file download. Can I achieve what I need using XMLHttpRequest() or am I going it about it the wrong way? Thanks

  • Why NOT use POST method here?

    - by Camran
    I have a classifieds website. In the main page (index) I have several form fields which the user may or may not fill in, in order to specify a detailed search of classifieds. Ex: Category: Cars Price from: 3000 Price to: 10000 Color: Red Area: California The forms' action is set to a php page: <form action='query_sql.php' method='post'> In query_sql.php I fetch the variables like this: category=$_POST['category']; etc etc... Then query MySql: $query="SELECT........WHERE category='$category' etc etc.... $results = mysql_query($query); Then I simply display the results of the query to the user by creating a table which is filled in dynamically depending on the results set. However, according to an answer by Col. Shrapnel in my previous Q I shouldn't use POST here: http://stackoverflow.com/questions/3004754/how-to-hide-url-from-users-when-submitting-this-form The reason I use post is simply to hide the "one-page-word-document" long URL in the browsers adress bar. I am very confused, is it okay to use POST or not? It is working fine both when I use GET or POST now... And it is already on a production server... Btw, in the linked question, I wasn't referring to make URL invisible (or hide it) I just wanted it too look better (which I have accomplished with mod_rewrite). UPDATE: If I use GET, then how should I make the url better looking (beautiful)? Check this previous Q out: http://stackoverflow.com/questions/3000524/how-to-make-this-very-long-url-appear-short

  • How do I implement "cash out" on my site using PayPal?

    - by Alex
    I have a credit system set up on my site where user A can purchase a document from user B, let's say for 1 credit and user B's account gets credited, let's say for $1. User B can then "cash out" and recieve the money they earned from my (the site's) PayPal account into their PayPal account (let's assume that their email address is valid for now). When user A purchases a credit, they are taken to PayPal where they can login and complete the purchase, for this purpose I have an IPN listener set up on my site that stores credit information to my site's database. However, I can't find a mechanism to send the "cash out" information (i.e. user's email and amount to be paid) to PayPal. To elaborate: I understand that PayPal sends the IPN when someone purchases from me, but how do I post from my site to PayPal when the user clicks the "cash out" button? I have seen mention of Mass Pay, but can't seem to locate any code samples to go from. Am I missing something, or is there perhaps a different (and better) way to do this? Thanks!

  • open Fancybox in tabs

    - by Prashant
    Hello all. I am using PHP + jQuery + Fancybox in my project. I have multiple tabs that get created dynamically. I have got a star icon on every tab header and on clicking them I want to open a fancybox. My tabs are basically ul-li with following dynamic code. $("#tabs").append("<li class='current'><a class='tab' id='tab_" + tabCnt + "<a href='#loginBox_div' class='login_link'> <img src='star.png' style='cursor:pointer'/> </a>" + "<a href='javascript:void(0);' class='remove'>x</a></li>"); in my index file : $(document).ready(function() { $("a.login_link").fancybox({ 'titlePosition' : 'inside', 'transitionIn' : 'none', 'transitionOut' : 'none' }); }); The problem is that when I click on star icon of first tab, the loginBox_div (fancybox) opens properly. But when my second tab is created and when I click on its star icon, the fancybox is not opening although the class is applied in second and successive tabs. No javascript errors too. Please show me the way. Thank you.

  • Google Maps - custom icons with infoWindows

  • How can I format Custom Data and display in autocomplete when source is an DB

    - by Andres Scarpone
    so I'm trying to get some info in the auto-complete widget like it's shown in the JQuery UI demo Demo, the only problem is they use a variable that they fill with the data they want to show, I instead want to access the data and the different description and stuff using a Data Base in MySQL, for this I have changed the source to use another php page that looks up the info. here is the code for the Auto-complete, I really don't understand the methods so I haven't changed it from the basic search. This is the JS: $(document).ready((function(){ $( "#completa" ).autocomplete({ source: "buscar.php", minLength: 1, focus: function (event, ui){ $("#completa").val(ui.item.val); return false; }; })); This is what I have in buscar.php: <?php $conec = mysql_connect(localhost, root, admin); if(!$conec) { die(mysql_error()); } else { $bd = mysql_select_db("ve_test",$conec ); if(!$bd) { die(mysql_error()); } } $termino = trim(strip_tags($_GET['term']));//Obtener el termino que envia el autocompletar $qstring = "SELECT name, descripcion FROM VE_table WHERE name LIKE '%".$termino."%'"; $result = mysql_query($qstring);//Solicitud a la Base de Datos while ($row = mysql_fetch_array($result,MYSQL_ASSOC))//Realizar un LOOP sobre los valores obtenidos { $row['value']=htmlentities(stripslashes($row['name'])); $row_set[] = $row;//build an array } echo json_encode($row_set);//Enviar los datos al autocompletar en codificacion JSON, Altamente Necesario. ?

  • MVC and jQuery data retrieval.

    - by user337542
    Hello, I am using mvc and jQuery and I am trying to display someone's profile with some additional institutions that the person belongs to. I am new to this but I've done something like this in ProfileControler: public ActionResult Institutions(int id) { var inst = fr.getInstitutions(id); return Json(inst); } getInstitutions(id) returns Institution objects(with Name, City, Post Code etc.) Then in a certain View I am trying to get the data with jQuery and display them as follows: $(document).ready(function () { $.post("/Profile/Institutions", { id: <%= Model.Profile.userProfileID %> }, function (data) { $.each(data, function () { var new_div = $("<div>"); var new_label = $("<label>"); new_label.html(this.City); var new_input_b = $("<input>"); new_input_b.attr("type", "button"); new_div.append(new_label); new_div.append(new_input_b); $("#institutions").append(new_div); }); }); }); $("#institutions") is a div where i want to display all of the results. .post works correct for sure because certain institutions are retrieved from database, and passed to the view as Json result. But then I am affraid it wont itterate with .each. Any help, coments or pointing in some direction would be much appriciated

    Hello Everybody, my problem is, I want to validate an email adresse with jquery. Not only the syntax but rather if the email is already registrated. There are some tutorials but they are not working! At first the Jquery Code: <script id="demo" type="text/javascript"> $(document).ready(function() { // validate signup form on keyup and submit var validator = $("form#signupform").validate({ rules: { Vorname: { required: true, minlength: 3 }, Nachname:{ required: true, minlength: 4 }, password: { required: true, minlength: 5 }, password_confirm: { required: true, minlength: 5, equalTo: "#password" }, Email: { required: true, email: true, type: "POST", remote: "remotemail.php" }, dateformat: "required", ... </script> And now the PHP Code: <?php include('dbsettings.php'); $conn = mysql_connect($dbhost,$dbuser,$dbpw); mysql_select_db($dbdb,$conn); $auslesen1 = "SELECT Email FROM flo_user"; $auslesen2 = mysql_query($auslesen1,$conn); $registered_email = mysql_fetch_assoc($auslesen2); $requested_email = $_POST['Email']; if( in_array($requested_email, $registered_email) ){ echo "false"; } else{ echo "true"; } ?> I tried return TRUE/ return FALSE as well, but this displays "Email is registrated" all the time. json_encode didn't work as well.

  • jQuery + External javascript: How to embed videoplayer in div

    - by Dennis
    I just started with jQuery and so far I have a really good impression of the framework. But now I have a problem that I can't figure out on myself. I want to embed an external javascript file that loads a videoplayer and displays it. If I include the <script>...</script> directly in HTML it loads just fine. But when I try to load it with jQuery it has very different behaviors in several browsers but it doesn't work in a single one. Either the player is not loaded at all or it doesn't update the selected div but reloads the player on a blank page. This is the source: <html> <head> <style type="text/css"> div#test { width: 100%; height: 500px; margin: 10px auto; padding: 5px; border: 1px solid #777; background-color: #fbca93; text-align: center; } </style> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script> $(document).ready(function(){ var video = "<script type=\'text\/javascript\' src=\'http:\/\/www.physicalfitnet.com\/video_syndication\/embed\/jssingle.aspx?vid=651&pub=9DF8233261D101B86368400385B8FF2E\'><\/script>"; $("div#test").html(video); }); </script> </head> <body> <div id="test"> Hi</div> </body> </html> I uploaded everything to http://kernast.de/test ... any help is appreciated.

  • How can I restore the "auto" values with for list-style-type in nested unordered lists with CSS?

    - by Michael
    By default, an unstyled set of nested <ul> lists looks like this (in Chrome, Firefox, and IE at least): The top level has a list-style-type of disc, the next level is circle, and subsequent levels are square. If I include a stylesheet that changes the list-style-type to none, is there a simple way to revert back to the "automatic bullet types" later in the document? (e.g., override with a subsequent CSS definition or JavaScript style change) Basically, I'm looking for something like list-style-type: auto; (which is apparently not valid and has no effect): <style type="text/css"> ul { list-style-type: none; } ul { list-style-type: auto; } /* Does not work */ </style> Setting the list-style-type back to disc changes every bullet in the list and I no longer see different bullets at different levels, so that doesn't work either. Is the only way to accomplish this by explicitly defining styles for every level? e.g.: <style type="text/css"> ul { list-style-type: disc; } ul ul { list-style-type: circle; } ul ul ul { list-style-type: square; } </style>

  • Syntax for documenting JSON structure

    - by Roman A. Taycher
    So I'm trying to document the format of the json returned by an api I am writing against and I'd like to know if there is any popular format for the documentation of json structure. Note I'm not trying to to test or validate anything, I'm just using this for documentation. Also some ways to add comments to non-constants(items always returned w/ the same value) would be nice. This the not totally thought out scheme I'm currently using: Plain names refer to identifiers or types. Some types have type-comment Strings that appear to be constant(always returned for that type of request) strings are "str" Constant Numbers would be just the number Constant null is null Booleans are true/false for constant booleans or Boolean otherwise [a,b,c] are lists with 3 items a,b,c [... ...] is a list of repeating elements of some types/constants/patterns {a:A,b:B,c:c} and {... ...} is the same for a dictionary. example: story := [header,footer] header := {"data":realHeader,"kind":"Listing"} realHeader := {"after": null, "before": null, "children": [{"data": realRealHeader, "kind": "t3"}], "modhash": ""} footer := {"data":AlmostComments,"kind":"Listing"} AlmostComments := {"data": {"after": null, "before": null, "children": comments, "modhash": ""}, "kind": "t1"} comments := [...{"data":comment, "kind":"t1"}...] realRealHeader := {"author": string, "clicked": boolean, "created": int, "created_utc": int, "domain": "code.reddit.com", "downs": int, "hidden": boolean, "id": string-id, "is_self": boolean, "levenshtein": null, "likes": null, "media": null, "media_embed": { }, "name": string-id, "num_comments": int, "over_18": false, "permalink": string-urlLinkToStoryStartingFrom/r, "saved": false, "score": int, "selftext": string, "selftext_html": string-html, "subreddit": string-subredditname, "subreddit_id": string-id, "thumbnail": "", "title": string, "ups": int, "url": "http://code.reddit.com/" } comments := { "author": string, "body": string-body_html-wout-html, "body_html": string-html-formated, "created": int, "created_utc": int, "downs": int, "id": string-id, "levenshtein": null, "likes": null, "link_id": string-id, "name": string-id", "parent_id": string-id, "replies": AlmostComments or null, "subreddit": string-subredditname, "subreddit_id": string-id, "ups": int }

  • jQuery AJAX PHP JSON problem

    - by Curro
    Hi Gurus I'm facing the problem of receiving an empty array when I do an AJAX request in the following way: This is the code I'm executing in JavaScript: <script type="text/javascript" src="lib/jquery.js"></script> <script type="text/javascript" src="lib/jquery.json.js"></script> <script type="text/javascript"> $(document).ready(function(){ /* Preparar JSON para el request */ var mJSON = new Object; mJSON.id_consulta = new Array; for (var i=0; i<3; i++){ mJSON.id_consulta[i] = new Object; mJSON.id_consulta[i].id = i; } var sJSON = $.toJSON(mJSON); $.ajax({ type: "POST", url: "getUbicaciones.php", data: sJSON, dataType: "json", contentType: "application/json; charset=utf-8", success: function(respuesta){ alert(respuesta); }, error: function (request,error){ alert("Error: " + request.statusText + ". " + error); } }); }); </script> And this is the code under PHP: <?php /* Decodificar JSON */ $m_decoded = $_POST; print_r($m_decoded); exit; ?> And all I get from this, using Chrome's Developer Tools is an empty array: Array ( ) Any clues on what am I doing wrong? The string sJSON is being encoded correctly, this is what I get when I do an "alert" on that one: {"id_consulta":[{"id":1},{"id":2},{"id":3}]} Thank you everyone in advance!

  • Changing <object> height and width works in Chrome but not Firefox or IE. Why?

    - by Michael Hopkins
    I am making a site with two Youtube videos. These videos use the raw embed code from Youtube. The site's design doesn't work with any of the default Youtube sizes, so I am writing code to automatically resize the video. Here is my code. There will never be more than these two tags on the page, otherwise I'd do a better job selecting the videos. <script language='JavaScript' type='text/javascript'> var x=document.getElementsByTagName('object'); x.[0].width='350'; x.[0].height='350'; x.[1].width='350'; x.[1].height='350'; </script> For reference, here's a sample default Youtube embed that the code might alter: <object width="480" height="385"> <param name="movie" value="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed> </object> In Chrome, the video players sit perfectly in a 350x350 box. In IE and FF (latest versions), the videos are the unchanged, normal size. I cannot find anything in Google that explans why this won't work. I have tried using setattribute, for loops, adjusting both and , single-quotes and double-quotes, etc. Any ideas what is going wrong?
