  • JavaScript, transform object into array

    - by Šime Vidas
    I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

  • Escaping and unescaping a string with single and double quotes in Javascript

    - by Reina
    I have a search box that a user can search for any string including single AND double quotes, once they have searched, the backend is passing the keyword back to me so I can put it back in the box. I don't know what the string is so I can't escape quotes myself, below is an example: var keyword = "hello"; $("#selectionkeywords").val(); The issue I am having is that if the user enters "hello" the keyword becomes ""hello"" and I get this error: missing ) after argument list [Break On This Error] jQuery("#selectionkeywords").val(""hello""); The user could also enter single quotes so that rules it out as well. I tried using escape unescape but I still have the same issue e.g. escape(""hello"") I could get the value in an unescaped format e.g. "hello" but I don't know what to do with it, escape doesn't work on it I end up with this %26%23034%3Bhello%26%23034%3B So I'm pretty much stuck at the moment as I can't do anything to the string, any ideas?

  • Javascript - remove part of cookie with a split('|') like array

    - by MgS
    I'm abit stuck. I'm using jQuery. I have a cookie which has the value such as : 1,something|2,somethingg|1,something We are treating it as [0] as id and [1] as name. I need to remove ONE where the id == '1' for example, this will leave the cookie like this: 1,something|2,somethingg How do I go about this, it will probally be in a loop, but not sure how to remove one of them. I have this so far: function removeItem(id){ var cookieName = 'myCookie'; var cookie = $.cookie(cookieName); if(cookie){ var cookie = cookie.split('|'); $(cookie).each(function(index){ var thisCookieData = this.split(','); if(thisCookieData[0] == id ){ } }); }

  • How do I return a variable in javascript?

    - by bmckim
    I am working with the google maps API and whenever I return the variable to the initialize function from the codeLatLng function it claims undefined. If I print the variable from the codeLatLng it shows up fine. var geocoder; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(40.730885,-73.997383); var addr = codeLatLng(); document.write(addr); } function codeLatLng() { var latlng = new google.maps.LatLng(40.730885,-73.997383); if (geocoder) { geocoder.geocode({'latLng': latlng}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { if (results[1]) { return results[1].formatted_address; } else { alert("No results found"); } } else { alert("Geocoder failed due to: " + status); } }); } } prints out undefined If I do: var geocoder; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(40.730885,-73.997383); codeLatLng(); } function codeLatLng() { var latlng = new google.maps.LatLng(40.730885,-73.997383); if (geocoder) { geocoder.geocode({'latLng': latlng}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { if (results[1]) { document.write(results[1].formatted_address); } else { alert("No results found"); } } else { alert("Geocoder failed due to: " + status); } }); } } prints out New York, NY 10012, USA

  • Javascript 'class' and singleton problems

    - by Kucebe
    I have a singleton object that use another object (not singleton), to require some info to server: var singleton = (function(){ /*_private properties*/ var myRequestManager = new RequestManager(params, //callbacks function(){ previewRender(response); }, function(){ previewError(); } ); /*_public methods*/ return{ /*make a request*/ previewRequest: function(request){ myRequestManager.require(request); //err:myRequestManager.require is not a func }, previewRender: function(response){ //do something }, previewError: function(){ //manage error } }; }()); This is the 'class' that make the request to the server function RequestManager(params, success, error){ //create an ajax manager this.param = params; this._success = success; //callbacks this._error = error; } RequestManager.prototype = { require: function(text){ //make an ajax request }, otherFunc: function(){ //do other things } } The problem is that i can't call myRequestManager.require from inside singleton object. Firebug consolle says: "myRequestManager.require is not a function", but i don't understand where the problem is. Is there a better solution for implement this situation?

    - by Stefano
    Hi guys I have a select input on my page. this select input displays/hides fields in the form. This all works fine. But the problem is that if i submit the form and lack some necessary fields, it doesnt set the select to the right value afterwards. I just cant get the embedded ruby to work! it keeps escaping the whole thing... here my code: $(document).ready(function() { $("#profile_sex").val('<%= @profile.sex %>') $("#profile_sex").change(function(){ ($(this).val() == "Frau") ? $('#form-female').show() : $('#form-female').hide(); ($(this).val() == "Mann") ? $('#form-male').show() : $('#form-male').hide(); if ($(this).val() == "Paar") { $('#form-female').show(); $('#form-male').show(); } }); }); why doesnt this work??? I dont get any error or anything it just sets the value to "<%= @profile.sex =" I was googling and searching about on stack overflow and railscasts, the rails API, everything. Im seriously confused... thanks for your help.

  • Programmatically triggering events in Javascript for IE using jQuery

    - by Dan Herbert
    When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

  • How to get array keys in Javascript?

    - by DisgruntledGoat
    I have an array created with this code: var widthRange = new Array(); widthRange[46] = { sel:46, min:0, max:52 }; widthRange[66] = { sel:66, min:52, max:70 }; widthRange[90] = { sel:90, min:70, max:94 }; I want to get each of the values 46, 66, 90 in a loop. I tried for (var key in widthRange) but this gives me a whole bunch of extra properties (I assume they are functions on the object). I can't use a regular for loop since the values are not sequential.

  • JavaScript using toString on a Function object to read text content

    - by mseeley
    Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

  • javascript error: variable is not defined

    - by Hristo
    to is not defined [Break on this error] setTimeout('updateChat(from, to)', 1); I'm getting this error... I'm using Firebug to test and this comes up in the Console. The error corresponds to line 71 of chat.js and the whole function that wraps this line is: function updateChat(from, to) { $.ajax({ type: "POST", url: "process.php", data: { 'function': 'getFromDB', 'from': from, 'to': to }, dataType: "json", cache: false, success: function(data) { if (data.text != null) { for (var i = 0; i < data.text.length; i++) { $('#chat-box').append($("<p>"+ data.text[i] +"</p>")); } document.getElementById('chat-box').scrollTop = document.getElementById('chat-box').scrollHeight; } instanse = false; state = data.state; setTimeout('updateChat(from, to)', 1); // gives error }, }); } This links to process.php with function call getFromDB and the code for that is: case ('getFromDB'): // get the sender and receiver user IDs from their user names $from = mysql_real_escape_string($_POST['from']); $query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$from' LIMIT 1"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_assoc($result); $fromID = $row['user_id']; $to = mysql_real_escape_string($_POST['to']); $query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$to' LIMIT 1"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_assoc($result); $toID = $row['user_id']; $query = "SELECT * FROM `Messages` WHERE `from_id` = '$fromID' AND `to_id` = '$toID' LIMIT 1"; $result = mysql_query($query); while($row = mysql_fetch_assoc($result)) { $text[] = $line = $row['message']; $log['text'] = $text; } break; So I'm confused with the line that is giving the error. setTimeout('updateChat(from,to)',1); aren't the parameters to updateChat the same parameters that came into the function? Or are they being pulled in from somewhere else and I have to define to and from else where? Any ideas how to fix this error? Thanks, Hristo

How to settle the problem down? Here's similiar code I use: function sendRuest(someargums) { /* some code */ var the_variable; /* some code */ //here's that other function request.onreadystatechange = function() { if (request.readyState == 4) { switch (request.status) { case 200: //here the variable should be changed the_variable = request.responseXML; /* a lot of code */ //somewhere here the function closes } return the_variable; } var data = sendRequest(someargums); //and trying to read the data I get the undefined value

  • javascript and css loadings

    I was wondering, If I have, let's say 6 javascripts includes on a page and 4-5 css includes as well on the same page, does it actually makes it optimal for the page to load if I do create one file or perhaps two and append them all together instead of having bunch of them?

  • [Javascript] Prevent an element from being the target in a document mouseover

    - by Sander
    I'm building an firebug-like inspection tool for my page. When the mouse enters an element, the element should be highlighted. Now I'm creating an element which I position absolute on top of the target element, this however means the next mousemove event (which is bound to the document) will fire with the actual "highlight element" as the target. Is there a way to prevent the "highlight element" from being the target element in the mousemove event? The element already has a transparant background.

  • JavaScript: function returning NAN

    - by Michael
    I'm working on a codecademy.com lesson with instructions to write the calculateTotal function below. When I click run, it's returning NaN. Anyone know what's wrong with the calculateTotal function as I wrote it that's making it return NaN. Note, I understand that NaN means not a number... // runner times var carlos = [9.6,10.6,11.2,10.3,11.5]; var liu = [10.6,11.2,9.4,12.3,10.1]; var timothy = [12.2,11.8,12.5,10.9,11.1]; // declare your function calculateTotal here var calculateTotal = function(raceTimes){ var totalTime; for(i = 0; i < raceTimes.length; i++){ totalTime += raceTimes[i]; return totalTime; } }; var liuTotal = calculateTotal(liu); console.log(liuTotal);

  • How to initiate JavaScript Callback with MVC2 using RenderAction

I was curious what the best way to handle this is. I can get the control specific callback fired off by placing myUserControlCallback(); in the user control itself. I'm just not sure how to run something like allControlsRendered();. Any ideas?
