  • Dojo and Ajax - rendering widgets

    - by Michael Merchant
    I'm trying to load content into a Dojo content pane in a specific html tag and not replace the entire content pane. The html I'm loading includes a markup defined widget that I'd like to have rendered when the new row is loaded. So, I have a table that is being dynamically filled via ajax,ie: <body> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.5/dojo/dojo.xd.js" djConfig="parseOnLoad: true, isDebug:true"></script> <div id="table-pane" dojoType="dijit.layout.ContentPane"> <table class="test"> <tbody> <tr><td>Name</td><td>Year</td><td>Age</td></tr> <tr> <td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">Mike</span> </td> <td>2010</td> <td>12</td> </tr> </tbody> </table> </div> </body> <script> var html ='<tr><td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">John</span></td><td>2011</td><td>22</td></tr>'; dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.InlineEditBox"); dojo.require("dijit.form.Textarea"); dojo.addOnLoad(function(){ pane = dijit.byId("table-pane"); add_elem(); }); function add_elem(){ var node = $(".test tr:last"); node.after(html); dojo.addOnLoad(function(){ //Here I want to initiate any widgets that haven't been initiated pane.buildRendering(); }); }</script> How do I render the Dojo widget in the new table row?

  • IE not triggering keyboard event on a form with ONE FIELD

    - by raj
    I'm seeing my Friend's code here... <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> </form> </BODY> </HTML> and when he tried entering a value in the textbox and pressed enter, it did not call the detectEvent(). I said, it'll always call onSubmit on enter button..... and he surprised me, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> <p> Field1 <input type="text" id="text2"/> </p> </form> </BODY> </HTML> Now press enter, The function gets called..... Why so!? Why onKeyUp not called on forms with just one field.!!! am i missing something?

  • cross-domain data with AJAX using JSONP

    - by kooshka
    I'm trying to get data from Geobytes. One of the templates returns JSON and I need to cross-domain access it. I wrote these 2 functions function getCountry(ip) { var surl = "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt"; $.ajax({ url: surl, data: '{"ipaddress":"' + ip + '"}', dataType: "jsonp", jsonp: "callback", jsonpCallback: "jsonpcallback" }); } function jsonpcallback(rtndata) { alert(rtndata.message); } The call is executed but I get 1 warning: Resource interpreted as Script but transferred with MIME type text/html: "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt&callback=jsonpcallback&{%22ipaddress%22:%22200.167.254.166%22}&_=1353148931121" 1 Error: Uncaught SyntaxError: Unexpected token : The error is thrown on the returned data at {"geobytes":{"countryid":117, I think is maybe because it's 117 and not "117" but I obviously can't control the returned data How can I fix these 2 issues?

  • HLSL How can one pass data between shaders / read existing colour value?

    - by RJFalconer
    Hello all, I have 2 HLSL ps2.0 shaders. Simplified, they are: Shader 1 Reads texture Outputs colour value based on this texture Shader 2 Needs to read in existing colour (or have it passed in/read from a register) Outputs the final colour which is a function of the previous colour (They need to be different shaders as I've reached the maximum vertex-shader outputs for 1 shader) My problem is I cannot work out how Shader 2 can access the existing fragment/pixel colour. Is the only way for shaders to interact really just the alpha blending options? These aren't sufficient if I want to use the colour as input to my function.

  • Exception on malloc for a structure in C

    - by Derek
    Hi all, I have a structure defined like so: typedef struct { int n; int *n_p; void **list_pp; size_t rec_size; int n_buffs; size_t buff_size } fl_hdr_type; and in my code I Have a function for initlialization that has the following fl_hdr_type *fl_hdr; fl_hdr = malloc(sizeof(fl_hdr_type) + (buff_size_n * rec_size_n)); where those buffer size are passed in to the function to allow space for the buffers as well. The size is pretty small typically..100*50 or something like that..plenty of memory on this system to allocate it. Any ideas why this fails?

  • Edit the opposite side of a many to many relationship with django generic form

    - by Ed
    I have two models: class Actor(models.Model): name = models.CharField(max_length=30, unique = True) event = models.ManyToManyField(Event, blank=True, null=True) class Event(models.Model): name = models.CharField(max_length=30, unique = True) long_description = models.TextField(blank=True, null=True) In a previous question: http://stackoverflow.com/questions/2503243/django-form-linking-2-models-by-many-to-many-field, I created an EventForm with a save function: class EventForm(forms.ModelForm): class Meta: model = Event def save(self, commit=True): instance = forms.ModelForm.save(self) instance.actors_set.clear() for actor in self.cleaned_data['actors']: instance.actors_set.add(actors) return instance This allowed me to add m2m links from the other side of the defined m2m connection. Now I want to edit the entry. I've been using a generic function: def generic_edit(request, modelname, object_id): modelname = modelname.lower() form_class = form_dict[modelname] return update_object(request, form_class = form_class, object_id = object_id, template_name = 'createdit.html' ) but this pulls in all the info except the many-to-many selections saved to this object. I think I need to do something similar to this: http://stackoverflow.com/questions/1700202/editing-both-sides-of-m2m-in-admin-page, but I haven't figured it out. How do I use the generic update_object to edit the other side of many-to-many link?

  • create_or_update in ModelForm

    - by ykaganovich
    I want to have a ModelForm that can create_or_update a model instance based on the request parameters. I've been trying to cobble something together, but am realizing that my python fu is not strong enough, and the ModelForm implementation code is a quite hairy. I found this create_or_update snipplet for working with a Model, but I think it would be incredibly useful if it were integrated with a ModelForm. I would expect it to behave similarly to ModelForm.save(): class BetterModelForm(forms.ModelForm): def init(self, *args, **kwargs) def create_or_update(self): #magic return (instance, created, updated) Conversely I'd also be interested in hearing compelling reasons why this is not a good idea.

  • Is there a way to catch a MOUSE_UP Event over a static textfield in Flash?

    - by Jovica Aleksic
    When the user presses the mouse, and releases it over a static textfield with selectable text, no MOUSE_UP event is fired - not on the stage and also nowhere else. I experienced this when using a scrollbar class on a movieclip with a nested static textfield. When the user drags the scroll handle and releases the mouse over the textfield, the dragging/scrolling is stuck. To test this, create a new AS3 fla file, place a static textfield somewhere, and put in some text. Make sure the selectable property is checked in the properties panel. Add this script to the timeline: import flash.events.* function down(event:Event):void { trace('down'); } function up(event:Event):void { trace('up'); } stage.addEventListener(MouseEvent.MOUSE_DOWN, down) stage.addEventListener(MouseEvent.MOUSE_UP, up) Now test the movie and click the mouse. You will notice that trace('up') will not occur when you release the mouse over the textfield.

  • Anchoring the Action URL of a Form

    - by John
    Hello, I am using a function that leads users to a file called "comments2.php": <form action="http://www...com/.../comments/comments2.php" method="post"> On comments2.php, data passed over from the form is inserted into MySQL: $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); Then, later in comments2.php, I am using a query that loops through entries meeting certain criteria. The loop contains a row with the following information: echo '<td rowspan="3" class="commentname1" id="comment-' . $row["commentid"] . '">'.stripslashes($row["comment"]).'</td>'; For the function above, I would like the URL to be anchored by the highest value of "commentid" for id="comment-' . $row["commentid"] . '" How can this be done? Thanks in advance, John

  • Rotate a feature Image in Open Layers

    - by Ozaki
    I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

  • How to draw a transparent stroke (or anyway clear part of an image) on the iPhone

    - by devguy
    I have a small app that allows the user to draw on the screen with the finger. Yes, nothing original, but it's part of something larger :) I have a UIImageView where the user draws, by creating a CGContextRef and the various CG draw functions. I primarily draw strokes/lines with the function CGContextAddLineToPoint Now the problem is this: the user can draw lines of various colors. I want to give him the ability to use a "rubber" tool to delete some part of the image drawn so far, with the finger. I initially did this by using a white color for the stroke (set with the CGContextSetRGBStrokeColor function) but it did't work out...because I discovered later that the UIImage on the UIImageView was actually with transparent background, not white...so I would end up with a transparent image with white lines on it! Is there anyway to set a "transparent" stroke color...or is there any other way to clear the content of the CGContextRef under the user's finger, when he moves it? Thanks

  • Javascript Onclicks not working?

    - by Georges Oates Larsen
    I have a jQuery application which finds a specific div, and edit's its inner HTML. As it does this, it adds several divs with onclicks designed to call a function in my JS. For some strange reason, clicking on these never works if I have a function defined in my code set to activate. However, it works fine when calling "alert("Testing");". I am quite bewildered at this as I have in the past been able to make code-generated onclicks work just fine. The only thing new here is jQuery.

  • HTML5 Video Tag in Chrome - Why is currentTime ignored when video downloaded from my webserver?

    - by larson4
    I want to be able to play back video from a specific time using the HTML5 video tag (and currently only need to worry about Chrome). This is possible by setting the currentTime property of a video element. That works fine in Chrome with a video sourced from html5rocks.com, but is ignored when the same file is loaded from my own local webserver. Using the sample code from http://playground.html5rocks.com/#video_tag, I have arrived at the following HTML: <!DOCTYPE html> <html> <body> <video id="video1" width="320" height="240" volume=".7" controls preload=true autobuffer> <source src="http://playground.html5rocks.com/samples/html5_misc/chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> </video> <input type=button onclick="play()" value="play"> <input type=button onclick="setTime()" value="setTime"> <input type=button onclick="pause()" value="pause"> <script> var play=function() { document.getElementById("video1").play(); } var setTime=function() { document.getElementById("video1").currentTime=2; } var pause=function() { document.getElementById("video1").pause(); } </script> </body> </html> Using Chrome, if you Wait for the video to download for a bit (until the progress bar is about 10% in) Press setTime - you should notice the time jump to 2 seconds press play ...the video will start at 2 seconds in. But if I download the webm file in the source src to my local webserver, and change src to point locally: <source src="chrome_japan.webm" type='video/webm; codecs="vp8, vorbis"'/> ...then setting currentTime is complete ignored. No errors are showing in the developer tools console. Now, my webserver is serving this with mime type "video/webm", but it will be served like any old file -- not streamed. Do I need a webserver that streams in some specific way? What else could be at fault here? Note: The webserver is a proprietary platform and won't have any of the same exact settings or controls one might expect of Tomcat or some other commonly used webserver, though there may be other ways to achieve the same effect.

  • dojo connect mouseover and mouseout

    - by peirix
    When setting up dojo connections to onmouseover and onmouseout, and then adding content on mouseover, dojo fires the onmouseout event at once, since there is new content. Example: dojo.query(".star").parent().connect("onmouseover", function() { dojo.query("span", this).addContent("<img src='star-hover.jpg'>"); }).connect("onmouseout", function() { dojo.destroy(dojo.query("img", this)[0]); }); The parent() is a <td>, and the .star is a span. I want to add the hover image whenever the user hovers the table cell. It works as long as the cursor doesn't hover the image, because that will result in some serious blinking. Is this deliberate? And is there a way around it?

  • Show only one validation error-message using replaceWith

    - by timkl
    I am currently working with the jQuery validation plugin, and I want to show only one error-message before the form itself. Right now the validation shows all the error-messages on top of each others as they stack up, as you can see in my live example: http://timkjaerlange.com/foobar/stack-stuff/validate-test.html This is my jQuery: $(document).ready(function() { $("form").validate({ rules: { // bunch of rules here, left out to keep it simple }, messages: { // messages goes here }, errorElement: 'div', errorClass: 'error', errorPlacement: function(error, element) { error.insertBefore('form'); // this is what I've got $('div').replaceWith(error); // trying to replace the prev error } }); }); Anybody know how to this? Is this the best way to show only one error-message? Any help is highly appreciated.

  • Openlayers - LayerRedraw() / Feature rotation

    - by Ozaki
    TLDR: I have an Openlayers map with a layer called 'track' I want to remove track and add track back in. I have an image 'imageFeature' on a layer that rotates on load to the direction being set. I want it to update this rotation that is set in 'styleMap' on a layer called 'tracking'. I set the var 'stylemap' to apply the external image & rotation. The 'imageFeature' is added to the layer at the coords specified. 'imageFeature' is removed. 'imageFeature' is added again in its new location. Rotation is not applied.. As the 'styleMap' applies to the layer I think that I have to remove the layer and add it again rather than just the 'imageFeature' Layer: var tracking = new OpenLayers.Layer.GML("Tracking", "coordinates.json", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); styleMap: var styleMap = new OpenLayers.StyleMap({ fillOpacity: 1, pointRadius: 10, rotation: heading, }); Now wrapped in a timed function the imageFeature: map.layers[3].addFeatures(new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(longitude, latitude), {rotation: heading, type: parseInt(Math.random() * 3)} )); Type refers to a lookup of 1 of 3 images.: styleMap.addUniqueValueRules("default", "type", lookup); var lookup = { 0: {externalGraphic: "Image1.png", rotation: heading}, 1: {externalGraphic: "Image2.png", rotation: heading}, 2: {externalGraphic: "Image3.png", rotation: heading} } I have tried the 'redraw()' function: but it returns "tracking is undefined" or "map.layers[2]" is undefined. tracking.redraw(true); map.layers[2].redraw(true); Heading is a variable: from a JSON feed. var heading = 13.542; But so far can't get anything to work it will only rotate the image onload. The image will move in coordinates as it should though. So what am I doing wrong with the redraw function or how can I get this image to rotate live? Thanks in advance -Ozaki Add: I managed to get map.layers[2].redraw(true); to sucessfully redraw layer 2. But it still does not update the rotation. I am thinking because the stylemap is updating. But it runs through the style map every n sec, but no updates to rotation and the variable for heading is updating correctly if i put a watch on it in firebug.

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • The reason for MonadState get and put?

    - by CiscoIPPhone
    I'm reading the Monads chapter in Real World Haskell (chapter 14). A function is defined as follows: type RandomState a = State StdGen a getRandom :: Random a => RandomState a getRandom = get >>= \gen -> let (val, gen')= random gen in put gen' >> return val I don't really understand the purpose of the get and put functions here. I rewrote the function as following which seems to do the same thing and is more concise: getRandom2 :: Random a => RandomState a getRandom2= State $ \ s -> random s So my question is: What is the purpose of get and put?

  • Dependency Injection with @Inject in Weld (JSR-299 RI). How is the corresponding @Produces found?

    - by Thorbjørn Ravn Andersen
    I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic. My question is how the producer of a given object to be @Inject'ed is found? Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach. What is the trick?

  • [Flex 4] Removing sort arrows from AdvancedDataGridColumn Header.

    - by zeroDivisible
    Hello, I am doing this simple project using Flex 4 SDK and I got stuck with this simple problem: I have turned sortable property for AdvancedDataGridColumn to false, but the column header is still rendered as: As You can see, my label for this header is "06", but the column header is divided and it keeps the place for sort arrow. How can I change this? I would like my column header to contain only my label. I know that most probably I need to do some magic with AdvancedDataGridHeaderRenderer but I just started learning Flex and would like to receive some help. Thank You for help. Best regards, Mike.
