  • Cannot set property X of undefined - programatically created element

    - by Dave
    I am working on a class to create a fairly complex custom element. I want to be able to define element attributes (mainly CSS) as I am creating the elements. I came up with the below function to quickly set attrs for me given an input array: // Sample array structure of apply_settings //var _button_div = { // syle : { // position: 'absolute', // padding : '2px', // right : 0, // top : 0 // } //}; function __apply_settings(__el,apply_settings){ try{ for(settingKey in apply_settings){ __setting = apply_settings[settingKey]; if(typeof(__setting)=='string'){ __el[settingKey] = __setting; }else{ for(i in __setting){ __el[settingKey][i] = apply_settings[settingKey][i]; } } } }catch(ex){ alert(ex + " " + __el); } } The function works fine except here: function __draw_top(){ var containerDiv = document.createElement('div'); var buttonDiv = document.createElement('div'); __apply_settings(containerDiv,this.settings.top_bar); if(global_settings.show_x) buttonDiv.appendChild(__create_img(global_settings.images.close)); containerDiv.appendChild(buttonDiv); __apply_settings(buttonDiv,this.settings.button_div); return containerDiv; } The specific section that is failing is __apply_settings(buttonDiv,this.settings.button_div); with the error "Cannot set property 'position' of undefined". So naturally, I am assuming that buttonDiv is undefined.. I put alert(ex + " " + __el); in __apply_settings() to verify what I was working with. Surprisingly enough, the element is a div. Is there any reason why this function would be working for containerDiv and not buttonDiv? Any help would be greatly appreciated :) {EDIT} http://jsfiddle.net/Us8Zw/2/

  • Ember nested route. Load more models

    - by user3568719
    JsBin http://jsbin.com/EveQOke/153/ I know how to load more then one model to a route, using Ember.RSVP.hash. (see Jsbin Children menu). I use dynamic part to access one elem from a collection children/1. But i cant load more models to a nested resource. In my example i want to populate all the toys for a select, not just list the toys of the child. I have tried to access the model of the route children App.ChildRoute = Ember.Route.extend({ model: function(param){ return Ember.RSVP.hash({ allToys: this.modelFor("children"), child:this.store.find('child', param.child_id) }); } }); and use its model's toy property (since there have already loaded all of the toys) child.hbs <h4>All avaiable toys</h4> <table> {{#each toy in model.allToys.toys}} <tr> <td>{{toy.name}}</td> </tr> {{/each}} </table>

  • Chrome Extension contenteditable get and set caret position

    - by jwize
    I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

  • Jquery live not working in IE

    - by Kaskade
    Hi, I have some code that works fine in FF but not in IE. I have read other posts saying that the Jquery live method does not support change events but I am using a click event. Here is my code, it is inside $(document).ready(function(): $("a").live("click", function(e) { alert("link clicked"); //do stuff }); If FF the alert is fired but not in IE. When I use $("a").click it works fine, the problem is that I need to the function to be applied to links that do not exist when the page is first loaded (they will be created via ajax calls at a later stage). Do I have any options here. We are using jquery-1.4.1.min.js. Thanks in advance

  • jQuery: How to fire event when all asynchronous calls return?

    - by Jeremy
    I have a jQuery application that loads data from five asynchronous server calls. I do not want to display any data until all five calls return. (I plan on displaying a Loading message until that happens.) How can I detect when all five calls have returned? I considered having each callback method increment a variable (using jQuery's data() method, perhaps) and then waiting for the value to become 5. (I am not sure yet how I would listen for that event.) I do not think this is a very good solution, however. What would happen if two calls return at the same time? Is there a better way to do this?

  • How can I convert seconds to minutes in jQuery while updating an element with the current time?

    - by pghtech
    So I see a number of ways to display allot of seconds in a (static) hr/min/sec. However, I am trying to produce a visual count down timer: $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); My counter is reduced inside a SetInterval that triggers ever 1 second: //....... var counter = redirectTimer; jQuery('#WarningDialogMsg').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); //........ SetInternval( function() { counter -= 1; secCounter = Math.floor(counter % 60); minCounter = Math.floor(counter / 60); //....... $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); }, 1000) It is a two minute counter but I don't want to display 120 seconds. I want to display 1 : 59 (and counting down). I have managed to get it to work using the above, but my main question is: is there a more elegant way to accomplish the above? (note: I am redirecting once "counter == 0").

  • Exceptions thrown in jQuery AJAX callbacks swallowed?

    - by MikeWyatt
    Is there any way to handle exceptions thrown from AJAX callbacks in jQuery, other than adding a try..catch block to each callback? The error function is not called in this situation. $.ajax( { url: 'myurl.rails', success: function( data ) { throw 'Oh no!'; }, error: function ( xhr, textStatus, errorThrown ) { console.log( 'AJAX call failed', xhr, textStatus, errorThrown ); } } );

  • Custom Alignment and Backgrounds Through Greasemonkey

    - by Jivec
    I'm trying to implement something in greasemonkey and it is giving me a fair bit of trouble as I can't get it to work. I frequently use Wolfram Alpha (http://wolframalpha.com) for a lot of things. They have recently updated the home page with a new style. There are settings that you can edit on this page (http://www.wolframalpha.com/homesettings.html) As you would expect when you clear cookies you loose these settings. What I would like to do is have a greasemonky script that sets the background to what ever I like (which will stay also regardless of the state of your cookies). It would also be cool if this background was displayed the whole way through Wolfram Alpha (ie when you make queries too eg. http://www.wolframalpha.com/input/?i=stack+overflow ) The other thing I'm trying to implement but I'm struggling is to force the results pages to be left aligned so that the browser window can be smaller. If anyone could help me with this it would be appreciated, I have tried to do it my self but I'm unsure how to get it to work.

  • JQuery: Get length of JSON reply?

    - by Rosarch
    In a JQuery getJSON call, how can I tell the length of the JSON that's returned? function refreshRoomList() { $.getJSON('API/list_rooms', function (rooms) { if (rooms.length > 0) { $("#existing-room-list").empty(); $("#join-existing-room").text("Join existing room:"); // this shouldn't be here $.each(rooms, function (index, roomName) { var newChild = sprintf('<li><a href="room?key=%s">%s</a></li>', index, roomName); $("#existing-room-list").append(newChild); }); } else { $("#join-existing-room").text("No rooms found."); } }); } For some reason this doesn't work, but if I replace rooms.length > 0 with true, the full list of rooms is printed out.

  • jQuery Cluetip not activated until after hover or click event

    - by kenny99
    I'm not sure what is causing this, but I am using cluetip and binding it to a live event (either click or mouseenter), but in each situation the cluetip isn't firing until after one click or hover event. I am using the live event for ajax loaded content, but I'm also having this issue with non-Ajax loaded content. I'm not sure why this is happening - can anyone see where I might be going wrong? Many thanks. $("a.jTip").live("click", function(){ $('a.jTip').cluetip({ attribute: 'href', cluetipClass: 'jtip', arrows: true, activation: 'click', ajaxCache: false, dropShadow: true, sticky: true, mouseOutClose: false, closePosition: 'title' }) return false; });

  • Java-script object - get variable name

    - by Mikk
    Hi, To begin with, I'm not even sure, if it is the right way to do it. Let's say, i have script (jquery included) like this: foo = function() { this.bar = function() { alert('I\'m bar'); } this.test = function() { $('body').append('<a onclick="my_var.bar();">Click me</a>'); } this.test(); } var my_var = new foo(); Is there any way, i could make variable "my_var" dynamic inside function "foo". So I could do something like $('body').append('<a onclick="'+the_variable_which_im_assigned_to+'.bar();">Click me</a>'); Thank you

  • Submit form with JS

    - by Thomas
    Im working with a shopping cart plugin and that uses a basic form on the product page to submit values like price, product name, etc.. The problem is that the plugin uses a standard submit button to send the values and I would like to replace said button with a prettier custom jquery rollover. In order to make this happen I used some JS and tossed a link around my custom submit button: <a href="#" onclick="document.forms[0].submit()" value="Add to Cart" onsubmit="return ReadForm(this, true);"> <img class="fade" src="style/img/add_btn.jpg" style="background: url(style/img/add_ro.png);" alt=""/> </a> The form submits and the user is redirected to the homepage but the data in the form doesn't seem to get submitted and the product never gets added to the 'cart' page. I suspect that the form is getting submitted but I am failing to fire some additional JS function that submits the data. The plugin adds some JS to the top of the page: <!-- // function ReadForm (obj1, tst) { // Read the user form var i,j,pos; val_total="";val_combo=""; for (i=0; i<obj1.length; i++) { // run entire form obj = obj1.elements[i]; // a form element if (obj.type == "select-one") { // just selects if (obj.name == "quantity" || obj.name == "amount") continue; pos = obj.selectedIndex; // which option selected val = obj.options[pos].value; // selected value val_combo = val_combo + "(" + val + ")"; } } // Now summarize everything we have processed above val_total = obj1.product_tmp.value + val_combo; obj1.product.value = val_total; } //--> If you want to check out the the site in question, take a look here and click 'add to cart button': http://hardtopdepot.com/?p=34 You can see the cart at the top: http://hardtopdepot.com/?page_id=50 Any help would be super appreciated- thanks!

  • python interactive web data/forms/interface communicating with remote server

    - by decipher
    What's an efficient method (preferably simple as well) for communicating with a remote server and allowing the user to 'interact' with it (IE submit commands, user interface) via the web browser (IE a text box to input commands, and an text area for output, or various command-less abstracted interfaces)? I have the 'standalone' python code finished for communicating and working(terminal/console based right now). My primary concern is with re-factoring the code to suite the web, which involves establishing a connection (python sockets), and maintaining the connection while the user is logged on. some further details: currently using django framework for the basic back end/templates.

  • Javascript (JQuery) keyboard hijack problem

    - by user266564
    I'm making a typing tutor program using javascript. Everything is going well except that if activates browser hotkeys which disrupts the functionality of the program. When I press the single quote in Firefox it triggers "Quick find (links only)" short cut and in all browsers when I press space the page scrolls down a page. Everything is working fine outside of this. Here's the code in the head: <script type="text/javascript"> $(document).ready(function() { executeType(); }); </script> And the code I am using to capture the keyboard (simplified, but tested): function executeType() { $(document).keydown(function(event) { alert(event.keyCode); }); }
