  • Destructuring assignment problem

    - by Eli Grey
    Why does for ([] in iterable); work fine but [void 0 for ([] in iterable)] throw a syntax error for invalid left-hand assignment? For example, I would expect the following code to work, but it doesn't (the assertion isn't even done due to the syntax error): let (i = 0, iterable = (i for (i in [1, 2, 3, 4]))) { for ([] in iterable) i++; console.assertNotGreater([void 0 for ([] in iterable)].length, i); }

  • HTML 5 Canvas - Dynamically include multiple images in canvas

    - by Ron
    I need to include multiple images in a canvas. I want to load them dynamically via a for-loop. I tried a lot but in the best case only the last image is displayed. I check this tread but I still get only the last image. For explanation, here's my latest code(basically the one from the other post): for (var i = 0; i <= max; i++) { thisWidth = 250; thisHeight = 0; imgSrc = "photo_"+i+".jpg"; letterImg = new Image(); letterImg.onload = function() { context.drawImage(letterImg,thisWidth*i,thisHeight); } letterImg.src = imgSrc; } Any ideas?

  • Not all parameters get sent in jquery ajax call

    - by rksprst
    I have a strange error where my jquery ajax request doesn't submit all the parameters. $.ajax({ url: "/ajax/doAssignTask", type: 'GET', contentType: "application/json", data: { "just_a_task": just_a_task, "fb_post_date": fb_post_date, "task_fb_postId": task_fb_postId, "sedia_task_guid": sedia_task_guid, "itemGuid": itemGuid, "itemType": itemType, "taskName": taskName, "assignedToUserGuid": assignedToUserGuid, "taskDescription": taskDescription }, success: function(data, status) { //success code }, error: function(xhr, desc, err) { //error code } }); But using firebug (and debugging) I can see that only these variables are posted: assignedToUserGuid itemGuid itemType just_a_task taskDescription taskName It's missing fb_post_date, task_fb_postId, and sedia_task_guid I have no idea what would cause it to post only some items and not others? Anyone know? Data is sent to asp.net controller that returns jsonresult (hence the contentType) Any help is appreciated. Thanks!

  • Jquery AJAX and figuring out how NOT to nest callbacks for multiple reloads.

    - by David H
    I have a site with a few containers that need to load content dynamically via AJAX. Most of the links inside of the containers actually load new data in that same container. I.E: $("#navmenu_item1").click(function() { $("#navmenu").load(blah); }); When I click on a link, lets say "logout," and the menu reloads with the updated login status, none of the links now work because I would need to add a new .click into the callback code. Now with repeated clicks and AJAX requests I am not sure how to move forward from here, as I am sure nested callbacks are not optimal. What would be the best way to do this? Do I include the .click event inside the actual AJAX file being pulled from the server, instead of within index.php? Or can I somehow reload the DOM? Thanks for the help!

  • How to get around the jslint error 'Don't make functions within a loop.'

    - by Ernelli
    I am working on making all of our JS code pass through jslint, sometimes with a lot of tweaking with the options to get legacy code pass for now on with the intention to fix it properly later. There is one thing that jslint complains about that I do not have a workround for. That is when using constructs like this, we get the error 'Don't make functions within a loop.' for (prop in newObject) { // Check if we're overwriting an existing function if (typeof newObject[prop] === "function" && typeof _super[prop] === "function" && fnTest.test(newObject[prop])) { prototype[prop] = (function (name, func) { return function () { var result, old_super; old_super = this._super; this._super = _super[name]; result = func.apply(this, arguments); this._super = old_super; return result; }; })(prop, newObject[prop]); } This loop is part of a JS implementation of classical inheritance where classes that extend existing classes retain the super property of the extended class when invoking a member of the extended class. Just to clarify, the implementation above is inspired by this blog post by John Resig. But we also have other instances of functions created within a loop. The only workaround so far is to exclude these JS files from jslint, but we would like to use jslint for code validation and syntax checking as part of our continuous integration and build workflow. Is there a better way to implement functionality like this or is there a way to tweak code like this through jslint?

  • Extract form variable in AJAX response using jquery

    - by Jake
    All, I have a Jquery ajax request calling out a URL. The ajax response I receive is an HTML form with one hidden variable in it. As soon as my ajax request is successful, I would like to retrieve the value of the hidden variabl. How do I do that? Example: html_response for the AJAX call is : <html><head></head><body><form name="frmValues"><input type="hidden" name="priceValue" value="100"></form></body></html> $.ajax({ type: 'GET', url: "/abc/xyz/getName?id="+101, cache: false, dataType: "html", success: function(html_response) { //Extract form variable "priceValue" from html_response //Alert the variable data. } }); Thanks

  • iframe.document.body.scrollHeight is double the correct value

    - by Dean J
    <iframe name="asdf" id="asdf" onload="change_height(this)" src="asdf.jsp" width="250" scrolling="no" frameborder="0"></iframe> function change_height(iframe) { if (document.all) { // IE. ieheight = iframe.document.body.scrollHeight; iframe.style.height = ieheight; } else { // Firefox. ffheight= iframe.contentDocument.body.offsetHeight; iframe.style.height = ffheight+ 'px'; } } ieheight is twice the actual height when this runs in IE7; haven't tested on IE6. It's the same value if I use scrollHeight or offsetHeight. It's the correct height in Firefox. Before I patch this by just dividing the IE value /2, what's the right way to do this?

  • using moogaloop to embed a custom video player from Vimeo

    - by scullytr
    Anyone have any luck using Vimeo's moogaloop player? I'm wanting to use Vimeo's supposed API functions to create custom buttons to control the Vimeo player on my site. Here's the reference page for moogaloop: http://vimeo.com/api/docs/moogaloop I've been able to get the player to embed using SWFObject, but I can't seem to get the API functions to work (e.g. api_play()). Any help is greatly appreciated. Thanks! -Tim.

  • twitter bootstrap typeahead (method 'toLowerCase' of undefined)

    - by mmoscosa
    I am trying to use twitter bootstrap to get the manufacturers from my DB. Because twitter bootstrap typeahead does not support ajax calls I am using this fork: https://gist.github.com/1866577 In that page there is this comment that mentions how to do exactly what I want to do. The problem is when I run my code I keep on getting: Uncaught TypeError: Cannot call method 'toLowerCase' of undefined I googled around and came tried changing my jquery file to both using the minified and non minified as well as the one hosted on google code and I kept getting the same error. My code currently is as follows: $('#manufacturer').typeahead({ source: function(typeahead, query){ $.ajax({ url: window.location.origin+"/bows/get_manufacturers.json", type: "POST", data: "", dataType: "JSON", async: false, success: function(results){ var manufacturers = new Array; $.map(results.data.manufacturers, function(data, item){ var group; group = { manufacturer_id: data.Manufacturer.id, manufacturer: data.Manufacturer.manufacturer }; manufacturers.push(group); }); typeahead.process(manufacturers); } }); }, property: 'name', items:11, onselect: function (obj) { } }); on the url field I added the window.location.origin to avoid any problems as already discussed on another question Also before I was using $.each() and then decided to use $.map() as recomended Tomislav Markovski in a similar question Anyone has any idea why I keep getting this problem?! Thank you

  • Aborting jQuery().load()

    - by Daniel I-S
    The .load() function of the jQuery library allows you to selectively load elements from another page (subject to certain rules). I would like to know whether it is possible to abort the load process. In our application, a user can browse a list of items. They may choose to click a button which loads and displays additional information about an item from another document (which can take some time). If they choose a different item in the list whilst a .load() is still happening, I would like the loading to be aborted. Is this possible? Is it even worth it? Any ideas? Dan

  • Highstock set different colors for different markers

    - by user1651804
    I am tryting to develop a chart in Highstock where each marker got an individual color. When i push my Data in an Array like this : series.data.push([ parseInt(Math.round(myDate.getTime())), parseInt(Math.round(myDate.getHours())) ]); The Data is shown correctly, but when i try to set the color within each data-object like this, it doesn't work to show points. series.data.push([ { x: parseInt(Math.round(myDate.getTime())), y: parseInt(Math.round(myDate.getHours())), marker:{fillColor: 'red'}} ]); What am i missing? Update: When i inspect it with firebug i can see that the series is set correctly within the chart object. so why does it now show up? :/

  • jEditable - how do I get the edited textfield variable?

    - by Forkrul Assail
    I have a table that I use jEditable with. Saving to the server works, but the callback for refreshing my table element (that I just edited and saved to the server) does not work. /* Apply the jEditable handlers to the table */ $('#example tbody td').editable( '<%= url_for :controller => 'impact_matrix', :action => 'post', :scenario => params[:id] %>', { "callback": function( sValue, y ) { ^ goes missing var aPos = oTable.fnGetPosition( this ); oTable.fnUpdate( sValue, aPos[0], aPos[1] ); }, "submitdata": function ( value, settings ) { temp = value return { "row_id": this.parentNode.getAttribute('id') }; }, sValue (that I point to in the code) - seems to be blank. I do get values for aPos[0] and aPos[1], but not sValue. Could someone please explain to me 'what triggers the callback function?' Or, if I could just see where to get the 'newly edited text' and then just run fnUpdate() on that, I'd be fine. Thanks in advance for your help.

  • OpenLayers: Raise event when map is zoomed or moved by user

    - by David Pfeffer
    I'm using OpenLayers to display OpenStreetMap maps. (Though, I'd assume this should be general enough to work for any map product...) I'm displaying some very sophisticated vector overlays, and the amount and resolution of the features I'm returning from the server via GeoJSON to overlay has proven too much for many computers. What I'd like to do now instead is to only send data befitting the resolution of the current zoom, and fitting the current view port. This should be relatively easy to do using the GetResolution and CalculateBounds methods on the Map object. However, I don't know when to call these methods because I can't find a way to register a function to be called when the user pans the map (changing the view port) or zooms the map (changing the resolution and view port). How can I get a callback when the user pans or zooms the map?
