  • Excanvas does not work in IE8 at all

    - by Matt Null
    I simply cannot get excanvas to work at all. I have tried everything I can think of. I am even uploading the examples that come with excanvas to my website and testing them and they do not even work. I don't know if it has something to do with my server or what, but I haven't seen a working excanvas image yet. for instance... I this example comes with the excanvas package and it does not work for me... does anyone know what this could possibly be? thanks http://www.javascriptkids.com/tools/excanvas/examples/example1.html

  • How can I run a local Windows Application and have the output be piped into the Browser.

    - by Trey Sherrill
    I have Windows Application (.EXE file is written in C and built with MS-Visual Studio), that outputs ASCII text to stdout. I’m looking to enhance the ASCII text to include limited HTML with a few links. I’d like to invoke this application (.EXE File) and take the output of that application and pipe it into a Browser. This is not a one time thing, each new web page would be another run of the Local Application! The HTML/java-script application below has worked for me to execute the application, but the output has gone into a DOS Box windows and not to pipe it into the Browser. I’d like to update this HTML Application to enable the Browser to capture that text (that is enhanced with HTML) and display it with the browser. <body> <script> function go() { w = new ActiveXObject("WScript.Shell"); w.run('C:/DL/Browser/mk_html.exe'); return true; } </script> <form> Run My Application (Window with explorer only) <input type="button" value="Go" onClick="return go()"> </FORM> </body>

  • How I can get logged in user's info like email id,name,city etc. in Facebook with uId

    - by vaibhavbhalke
    Hi all Can any one help me to get logged in user's info like email id,name,city etc. with the help of Facebook uId . " Long uid = apiClient.getLoggedInUser ();" Users_getInfo is not useful. It returns No of users connected to _User & according that there info gets. If user login successfully using fb connect, Facebook gives us uid. However, I need to match the logged in user with our member's account If that member is not present in DB then want to register him and I'm trying to do that with e-mail(hashed) address and other info.

  • Client side templating with unknown variables

    - by Eirik Johansen
    Our company has an intranet consisting of several e-mail templates filled with variables (like [[NAME]], [[PROJECT]] and so on). I was thinking of implementing some sort of client side templating to make it easier to replace these variables with actual values. The problem is that among all the client side template solutions I've located so far, all of them seem to assume that the JS code knows all the template variables that exist in the markup, and none of them seem to be able to fetch a list of variables defined in the markup. Does anyone know of any solutions/plugin which makes this possible? Thanks in advance!

  • D3.js transition callback on frame

    - by brenjt
    Does anyone know how I could accomplish a per frame callback for a transition with D3. Here is and example of what I am doing currently. link.transition() .duration(duration) .attr("d", diagonal) .each("end",function(e) { if(e.target.id == current) show_tooltip(e.target) }); This currently calls the anonymous function for each element at the end of the animation. I would like to call it for every frame.

  • Reading URL Anchor on IE

    - by tominated
    Hi, I've got a page full of links to another page with anchors on the end (like this: index.html#anchor). On the page they point to, I have a script that is supposed to read where the anchor points to in order to display something. On firefox it works perfectly, But I've noticed that IE seems to remove the #anchor from the end of the url, so the script can't grab the text. Is there a way around this, without any server side code?

  • JQGrid and JQuery Autocomplete

    - by Neff
    When implementing JQGrid 4.3.0, Jquery 1.6.2, and JQuery UI 1.8.16 Ive come across an issue with the Inline edit. When the inline edit is activated, some of the elements get assigned an auto complete. When the inline edit is canceld or saved, the auto complete does not always go away (selecting text by double clicking it then hitting delete, then hitting escape to exit row edit). Leaving the auto complete controls in edit mode when the row is no longer considered in edit mode. Perhaps you can tell me if there is a problem with the initialization or if I you are aware of an event post-"afterrestorefunc" that the fields can be returned to their "original" state. Original state being displayed as data in the JQGrid row. I've tried removing the DOM after row close, .remove() and .empty(): ... "afterrestorefunc": function(){ $('.ui-autocomplete-input').remove(); } ... but that causes other issues, such as the jqgrid is not able to find the cell when serializing the row for data or edit, and requires a refresh of the page, not just jqgrid, to be able to once again see the data from that row. Auto complete functionality for the element is created on the double click of the row: function CreateCustomSearchElement(value, options, selectiontype) { ... var el; el = document.createElement("input"); ... $(el).autocomplete({ source: function (request, response) { $.ajax({ url: '<%=ResolveUrl("~/Services/AutoCompleteService.asmx/GetAutoCompleteResponse") %>', data: "{ 'prefixText': '" + request.term + "', 'contextKey': '" + options.name + "'}", dataType: "json", type: "POST", contentType: "application/json; charset=utf-8", success: function (data) { response($.map(data.d, function (item) { return { label: Trim(item), value: Trim(item), searchVal: Trim(item) } })) } }); }, select: function (e, item) { //Select is on the event of selection where the value and label have already been determined. }, minLength: 1, change: function (event, ui) { //if the active element was not the search button //... } }).keyup(function (e) { if (e.keyCode == 8 || e.keyCode == 46) { //If the user hits backspace or delete, check the value of the textbox before setting the searchValue //... } }).keydown(function (e) { //if keycode is enter key and there is a value, you need to validate the data through select or change(onblur) if (e.keyCode == '13' && ($(el).val())) { return false; } if (e.keyCode == '220') { return false } }); } Other Sources: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:inline_editing http://api.jqueryui.com/autocomplete/ Update: I tried only creating the autocomplete when the element was focused, and removing it when onblur. That did not resolve the issue either. It seems to just need the autocomplete dropdown to be triggered.

  • 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?

  • Adding js to a drupal node form

    - by googletorp
    In Drupal you can create your own nodetype in a custom module. Doing this you get to create your own form which is all very nice. However if you want to add js the form things get a bit more tricky. If you add the js in the form, the js will only be added form the form when it is loaded. If the user would post the form with validation errors, the form function is not run again and thus the js is not added. Normally you would just create a menu callback and add the js there, but for the node add form, this wont be a possible solution. So what is the best solution for adding js in a node add form, to keep it persistant when the form doesn't validate?

  • JQuery timer, how do I do this

    - by Roland
    Is there anyway to implement a timer for JQuery, eg. every 10 seconds it needs to call a js function. I tried the following window.setTimeout(function() { alert('test'); }, 1000); but this only executes ones and then never again.

  • Choose a local file w/o uploading the chosen file

    - by Austin Hyde
    I am making a simple development tool for myself using PHP on my local development server. I would like a way to have a simple file-chooser to select a file without uploading it, but just retaining the file path. This is useful, because I will be the only one using the tool, and so PHP will have access to the chosen file without having it uploaded. My first thought is to have a <input type="file"...>, but as far as I know, there's no way to prevent the upload from happening. Is there a way to do this?

  • 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

  • (solved) jQuery click and drag/scroll window: jagged movement

    - by Josh
    Edit: derp, using pageX/Y instead of clientX/Y -- apparently scrollBy expects input with that offset rather than the other. Jaggy movement gone. I am getting jagged movement when doing small scroll increments using the following bindings. Can anyone point me in the right direction for how to smooth this out? FYI, its intermittent. It seems like, if I click and hold for a second, then drag at a decent speed there are no problems. Edit: What the hell? I get this output on debug... obvious jog backwards and forwards. This will happen in succession and seems to have no correlation with the mouse, other than the mouse is moving. x 398 : 403 y 374 : 377 x 403 : 399 y 377 : 374 x 399 : 404 y 374 : 377 Josh sococo.client.panMap = function(e){ e.preventDefault(); var movex = sococo.client.currX - e.pageX ; var movey = sococo.client.currY - e.pageY; console.log( sococo.client.currX +" : " + e.pageX ); window.scrollBy(movex,movey); sococo.client.currY = e.pageY; sococo.client.currX = e.pageX; } $(document).mousedown( function(e){ e.preventDefault(); sococo.client.currX = e.pageX; sococo.client.currY = e.pageY; $(document).bind( "mousemove", sococo.client.panMap ); }); $(document).mouseup( function(e){ e.preventDefault(); $(document).unbind( "mousemove", sococo.client.panMap ); });

  • Custom Icon for Marker Clusterer

    - by Nyxynyx
    I am using Marker Clusterer library for Google Maps API V3. Now that I have the clusterer working, I want to change the default icon to a custom one. Prorblem: When I try to set the style property of the marker clusterer, the default icon still appears. Where did I go wrong? JS Code // Marker Clusterer var styles = {styles: [{ height: 53, url: "http://localhost/mywebsite/images/template/markers/cluster.png", width: 53 }, { height: 56, url: "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m2.png", width: 56 }, { height: 66, url: "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m3.png", width: 66 }, { height: 78, url: "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m4.png", width: 78 }, { height: 90, url: "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m5.png", width: 90 }]}; var mcOptions = {gridSize: 50, maxZoom: 15, styles: styles[styles]}; mc = new MarkerClusterer(map, [], mcOptions);

  • 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!

  • Simplest possible table entry editing / addition / deletion web toolkit (for use with php)

    - by Dave
    Hi, i'm building a website in php and i have tables presented that i need to allow the user to: 1. add new entry (only one at a time, which should appear as a new modal overlay) 2. delete multiple selected entries from 3. edit an existing entry (only one at one time, in a view similar to 1.) 4. re-arrange entries up and down. One by one is fine. Multiple / Grouping rearrangements are not not needed what jquery / js / anything toolkit would be the SIMPLEST to work with? (of course, i should be able to work with it in php). I did try hacking away at: http://www.ericmmartin.com/projects/simplemodal/ but had a terrible time trying to get it to work on editing some existing data (had problem passing data to it).

  • How can I create an HTML text field that has scrolling background images before it is clicked?

    - by Jeffrey
    I'm looking to add a textbox on my website that captures a single email address. Behind it, I would like a scrolling (or sliding) images to be a "hint" for what the field should be. Example: http://steamboat.com/ - the "Newsletter sign up" toward the top of the page. I can find plenty of jQuery plugins that provide a plain text "hint". Where should I start looking to add this additional affect. Note: I do not want to add any flash elements on the page.

  • Problem with multiple select removing more than 1 option

    - by SoLoGHoST
    Ok, there seems to be a problem with the JS Code for Opera browsers, as it only removes the last option tag that is selected within a multiple select tag, can someone please help me. Here is the HTML for this: <select id="actions_list" name="layouts" multiple style="height: 128px; width: 300px;"> <option value="forum">forum</option> <option value="collapse">collapse</option> <option value="[topic]">[topic]</option> <option value="[board]">[board]</option> </select> Ofcourse it's within a form tag, but there's a ton more code involved with this form, but here is the relevant info for this. Here is the JS that should handle this, but only removes the last selected option in Opera, not sure about other browsers, but it really needs to remove all selected options, not just the last selected option... argg var action_list = document.getElementById("actions_list"); var i = action_list.options.length; while(i--) { if (action_list.options[i].selected) { action_list.remove(i); } } What is wrong with this? I can't figure it out one bit :( Thanks :)
