• jquery slider control issue

  - by Geetha

  Hi All, I am using slider control to create a progress bar for media player. Problem: the max value and slider size is not matching. The video get complete before it reaches the end of the slider. Code: <script type="text/javascript" src="js/jquery.ui.core.js"></script> <script type="text/javascript" src="js/jquery.ui.slider.js"></script> <link type="text/css" href="CSS/demos.css" rel="stylesheet" /> <link type="text/css" href="CSS/jquery-ui.css" rel="stylesheet" /> $('#slider-constraints').slider("value", 0); $('#slider-constraints').slider("constraints", [0, 0]); $("#slider-constraints").slider({ max: document.mediaPlayer.SelectionEnd, animate: true, range: $R(0, document.mediaPlayer.SelectionEnd), values:(0,document.mediaPlayer.SelectionEnd), value: val, enforceConstraints: false, slide: function(event, ui) { document.mediaPlayer.currentPosition = ui.value; $('#slider-constraints').slider("constraints", [0, ui.value]); $('#slider-constraints').slider("value", ui.value); }, start: function(event, index) { document.mediaPlayer.currentPosition = index.value; $('#slider-constraints').slider("constraints", [0, index.value]); $('#slider-constraints').slider("value", index.value); } }); } // Haldler position window.setInterval(function() { if (document.mediaPlayer.PlayState != 2 && document.mediaPlayer.PlayState == 0) { $('#slider-constraints').slider("constraints", [0, 0]); $('#slider-constraints').slider("value", 0); } else { $('#slider-constraints').slider("constraints", [0, document.mediaPlayer.currentPosition]); } }, 3000); // Progressbar position window.setInterval(function() { if (document.mediaPlayer.PlayState != 2 && document.mediaPlayer.PlayState == 0) { $('#slider-constraints').slider("constraints", [0, 0]); $('#slider-constraints').slider("value", 0); } else { $('#slider-constraints').slider("value", document.mediaPlayer.currentPosition); } }, 3000); } <div id="slider-constraints" >&nbsp;</div>

• Accessing Current URL using Prototype

  - by Jason Nerer

  Hi folks, following Ryan Bates Screencast #114 I'm trying to generate endless pages using prototype. In difference to Ryan's showcase my URL called via the AJAX request shall be handled dynamically, cause I do not always call the same URL when the user reaches the end of my page. So my JS running in backround looks like that and uses document.location.href instead a fixed URL: var currentPage = 1; function checkScroll() { if (nearBottomOfPage()) { currentPage++; new Ajax.Request(document.location.href + '?page=' + currentPage, {asynchronous:true, evalScripts:true, method:'get'}); } else { setTimeout("checkScroll()", 250); } } function nearBottomOfPage() { return scrollDistanceFromBottom() < 10; } function scrollDistanceFromBottom(argument) { return pageHeight() - (window.pageYOffset + self.innerHeight); } function pageHeight() { return Math.max(document.body.scrollHeight, document.body.offsetHeight); } document.observe('dom:loaded', checkScroll); The question is: The code seems to work in Safari but fails in FF 3.6. It seems that FF calculates scrollHeight or offsetHeight differently. How can I prevent that? Thx in advance. Jason

• Call private methods and private properties from outside a class in PHP

  - by Pablo López Torres

  I want to access private methods and variables from outside the classes in very rare specific cases. I've seen that this is not be possible although introspection is used. The specific case is the next one: I would like to have something like this: class Console { final public static function run() { while (TRUE != FALSE) { echo "\n> "; $command = trim(fgets(STDIN)); switch ($command) { case 'exit': case 'q': case 'quit': echo "OK+\n"; return; default: ob_start(); eval($command); $out = ob_get_contents(); ob_end_clean(); print("Command: $command"); print("Output:\n$out"); break; } } } } This method should be able to be injected in the code like this: Class Demo { private $a; final public function myMethod() { // some code Console::run(); // some other code } final public function myPublicMethod() { return "I can run through eval()"; } private function myPrivateMethod() { return "I cannot run through eval()"; } } (this is just one simplification. the real one goes through a socket, and implement a bunch of more things...) So... If you instantiate the class Demo and you call $demo-myMethod(), you'll get a console: that console can access the first method writing a command like: > $this->myPublicMethod(); But you cannot run successfully the second one: > $this->myPrivateMethod(); Do any of you have any idea, or if there is any library for PHP that allows you to do this? Thanks a lot!

• Using Mapping Models to migrate between Core Data Object Models

  - by westsider

  I have a fairly simply scheme. Essentially, Run <-- Data (where a Run holds a data, e.g., Temperature, sampled from some sort of sensor). Now, it seems that sensors can have more than one measurement (e.g., Temperature and Humidity). So, a single Run could have multiple data samples. Hence, Run <-- Sample and Sample <-- Data. (And for simplicity I am leaving Run <-- Data in place, for now.) If I create a new mapping model, then things generally work - except that no new Samples are created, no relationships are established between Runs and Samples nor between Samples and Datas. I am trying to get mapping model to migrate my model but even the slightest change to the generated mapping model results in Cocoa error 134110. For example, if I take the "Sample" mapping (which has no Source) and set its Source to 'Run' (so that I can set Sample's inverse relationship 'run' appropriately) then the mapping changes its name to "RunToSample". There are two relationships handled in this mapping: data and run. The data property gets set automatically to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "DataToData", $source.dataSet) Following this example, I set the run property to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToRun", $source) Similarly, I set the 'sample' property mapping in RunToRun to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToSample", $source) and the 'sample' property in DataToData to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToSample", $source.run) So, what, I wonder, is going wrong? I have tried various permutations, such as leaving the 'inverse' relationships unspecified. But I continue to get the same error (134110) regardless. I imagine that this is a lot easier than it seems and that I am missing some fundamental but minor piece. I have also tried subclassing NSEntityMigrationPolicy and overriding -createDestinationInstancesForSourceInstance: but these efforts have met with much the same results. Thanks in advance for any pointers or (relevant :-) advice.

• Python class variables not defined with called from outside module

  - by Jimmy

  I am having some issues with calling a function outside of a module. The scenario is I have a small class library that is using turtle to do some drawing, the function within the module calls the classes also within the module and draws things, etc. This all works fine and dandy when I call the function from within the same file, but if I have another file and call myLib.scene() I get variable undefined errors. Code examples: a class class Rectangle(object): def __init__(self, pen, height=100, width=100, fillcolor=''): self.pen = pen self.height = height self.width = width self.fillcolor = fillcolor def draw(self, x, y): '''draws the rectangle at coordinates x and y''' self.pen.goto(x, y) if self.fillcolor: self.pen.fillcolor(self.fillcolor) self.pen.fill(True) self.pen.down() for i in range(0,4): self.pen.forward(self.height if i%2 else self.width) self.pen.left(90) and the calling function is this def scene(pen): rect = Rectangle(pen) rect.draw(100,100) when I put the line scene(turtle.Turtle()) into the same file I have no issues, the rectangle is drawn and everyone goes home happy. However, if I try to call it from a separate python file like so: myLib.scene(turtle.Turtle()) I get an error: NameError: global name 'pen' is not defined, in the for loop of my draw method. Even if the line above is in the same file it still bombs out. What is going on?

• How to keep unreachable code?

  - by Gabriel

  I'd like to write a function that would have some optional code to execute or not depending on user settings. The function is cpu-intensive and having ifs in it would be slow since the branch predictor is not that good. My idea is making a copy in memory of the function and replace NOPs with jumps when I don't want to execute some code. My working example goes like this: int Test() { int x = 2; for (int i=0 ; i<10 ; i++) { x *= 2; __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) x *= 2; // Op to skip or not x *= 2; } return x; } In my test's main, I copy this function into a newly allocated executable memory and replace the NOPs by a JMP 2 so that the following x *= 2 is not executed. The problem is that I would have to change the JMP operand every time I change the code to be skipped. An alternative that would fix this problem would be: __asm {NOP}; // to skip it replace this __asm {NOP}; // by JMP 2 (after the goto) goto dont_do_it; x *= 2; // Op to skip or not dont_do_it: x *= 2; This way, as a goto uses 2 bytes of binary, I would be able to replace the NOPs by a fixed JMP of alway 2 in order to skip the goto. Unfortunately, in full optimization mode, the goto and the x*=2 are removed because they are unreachable at compilation time. Hence the need to keep that dead code.

• HTTP Basic Authentication with HTTPService Objects in Adobe Flex/AIR

  - by Bob Somers

  I'm trying to request a HTTP resource that requires basic authorization headers from within an Adobe AIR application. I've tried manually adding the headers to the request, as well as using the setRemoteCredentials() method to set them, to no avail. Here's the code: <mx:Script> <![CDATA[ import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; private function authAndSend(service:HTTPService):void { service.setRemoteCredentials('someusername', 'somepassword'); service.send(); } private function resultHandler(event:ResultEvent):void { apiResult.text = event.result.toString(); } private function resultFailed(event:FaultEvent):void { apiResult.text = event.fault.toString(); } ]]> </mx:Script> <mx:HTTPService id="apiService" url="https://mywebservice.com/someFileThatRequiresBasicAuth.xml" resultFormat="text" result="resultHandler(event)" fault="resultFailed(event)" /> <mx:Button id="apiButton" label="Test API Command" click="authAndSend(apiService)" /> <mx:TextArea id="apiResult" /> However, a standard basic auth dialog box still pops up prompting the user for their username and password. I have a feeling I'm not doing this the right way, but all the info I could find (Flex docs, blogs, Google, etc.) either hasn't worked or was too vague to help. Any black magic, oh Flex gurus? Thanks. EDIT: Changing setRemoteCredentials() to setCredentials() yields the following ActionScript error: [MessagingError message='Authentication not supported on DirectHTTPChannel (no proxy).'] EDIT: Problem solved, after some attention from Adobe. See the posts below for a full explanation. This code will work for HTTP Authentication headers of arbitrary length. import mx.utils.Base64Encoder; private function authAndSend(service:HTTPService):void { var encoder:Base64Encoder = new Base64Encoder(); encoder.insertNewLines = false; // see below for why you need to do this encoder.encode("someusername:somepassword"); service.headers = {Authorization:"Basic " + encoder.toString()}; service.send(); }

• JavaScript types

  - by Alex Ivasyuv

  Hi, as per http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf JavaScript has 6 types: undefined, null, boolean, string, number, object. var und; console.log(typeof und); // <-- undefined var n = null; console.log(typeof n); // <--- **object**! var b = true; console.log(typeof b); // <-- boolean var str = "myString" console.log(typeof str); // <-- string var int = 10; console.log(typeof int); // <-- number var obj = {} console.log(typeof obj); // <-- object Question 1: Why null is object type, if it has to be a null type. Question 2: What about function? var f = function() {}; console.log(typeof f); // <-- function Variable f has "function" type. Why it doesn't specified in specification as separate type. Thanks,

• JQuery Simplemodal and Tabs Help Needed

  - by Dave R

  Hi, I've got an asp.net page containing a Textbox with an Autocomplete extender on it. It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete. On the "select", I then call the server using JQuery. I'm currently using $.get here.... The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected. if (sStatus == "success") { $.modal(sText, { overlayClose: true, appendTo:'form', onShow: function(dialog) { $("#ccTargets_tabContainer").tabs(); }, onClose: function(dialog) { $("#<%=TextBox1.ClientID%>").val(""); $.modal.close(); } }); $.ready(); } One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal. Now to the crux of my problem. If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal. I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help? I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too.... UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?

• Fade HTML element with raw javascript

  - by jnkrois

  It's my second question of the day related to the same problem, so I apologize for that. I was able to put together a function to "fade out" an element, and it works just fine, my problem is that when I try to reverse it, so the element "fades in" it does not work. I've tried to change the obvious, but I can't understand what I'm doing wrong. My code so far is as follows: Given I have a "div" like so: <div id="test" style="width:200px; height:200px; display:block; opacity:1; background-color:red;"></div> The JavaScript function that I'm using to fade it out is: var getElement = document.getElementById('test'); function fadeOut(elem, speed){ if(!elem.style.opacity){ elem.style.opacity = 1; } var desvanecer = setInterval(function(){ elem.style.opacity -= .02; if(elem.style.opacity < 0){ clearInterval(desvanecer); } }, speed / 50); } fadeOut(getElement, 500); Could somebody take a look at this and let me know what I'm doing wrong, all I want to do is "FADE IN" an element to an opacity equal to "1". By the way, I can't use jQuery, however I'm eager to learn this way. Thanks

• Retrieve parent node from selection (range) in Gecko and Webkit

  - by Jason

  I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

• How do I Pass Parameter in Ajax Url?

• jQuery Flow Control (if then from URL params)

  - by Ryan Max

  Strangely enough I am more familiar with jQuery than I am with javascript. I need to be able to add a class to the body tag of a document depending on what specific forum page i'm on in a phpbb forum. Due to the nature of phpbb I can't actually do this flow control in php, so I am using jquery. Here's my code (the first part is an extend that gets the url parameters like so http://www.mysite.com/viewforum.php?f=3 var forum = $.getUrlVar('f'); will make forum == 3 because of the nature of phpbb i can't really do any flow control with php. So I am using jquery. This is my code: $(document).ready(function(){ $.extend({ getUrlVars: function(){ var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; }, getUrlVar: function(name){ return $.getUrlVars()[name]; } }); }); $(document).ready(function(){ var forum = $.getUrlVar('f'); if (forum == 3){ $('body').toggleClass('black'); } }); Yet this isn't working. Any idea why not?

• Rotate a feature Image in Open Layers - ReApply StyleMap to layer.

  - 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? Debugging with firebug I now notice that "rotationv" is updating as per it should be. But when the point is destroyed then added again it does not apply the new rotation... Add: I realised that the "image" is applied as per the layer. So I need to figure out how to re apply the stylemap to the layer so it will trigger the "update" on the page. //redefine layer 2 so it can be updated - test.js is just a 0.0 ref// var layer2 = new OpenLayers.Layer.GML("Layer 2", "test.js", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); But even if I add the above into my function still no luck. Included map.addLayers([layer2]); into the function as well. Edit: Attaching stylemap: var styleMap = new OpenLayers.StyleMap({ "default": new OpenLayers.Style({ rotation: rotationv, labelXOffset: "0", labelYOffset: "-15", graphicZIndex: 1 }) });

• How to use visibilitychange event on Firefox Extensions

  - by Tom S.

  I'm trying to learn how to make a firefox extension. I want to create a toolbar that only shows up on a specific page. I can make the toolbar appear, but then it should become hidden when I open or switch to a new tab, or close the tab with that specific page. I don't understand how to make the visibilitychange event work though, no matter what I try nothing happens. window.addEventListener("load", function load(event){ window.removeEventListener("load", load, false); myExtension.init(); },false); var myExtension = { init: function (aEvent) { gBrowser.addEventListener("DOMContentLoaded", this.showToolbar, false); }, showToolbar: function(aEvent) { var doc = aEvent.originalTarget; if(doc.location.href=="http://www.google.ca/"){ eToolbar=document.getElementById("nav-toolbar"); eToolbar.hidden=false; //no matter how I change this line below it never does anything gBrowser.addEventListener("mozvisibilitychange", this.toggleToolbar, false); } }, toggleToolbar: function(aEvent) { eToolbar=document.getElementById("nav-toolbar"); if(document["mozVisibilityState"]=="mozHidden"){ eToolbar.hidden=true; } else { eToolbar.hidden=false; } } }

• Using cellUpdateEvent with YUI DataTable and JSON DataSource

  - by Rob Hruska

  I'm working with a UI that has a (YUI2) JSON DataSource that's being used to populate a DataTable. What I would like to do is, when a value in the table gets updated, perform a simple animation on the cell whose value changed. Here are some relevant snippets of code: var columns = [ {key: 'foo'}, {key: 'bar'}, {key: 'baz'} ]; var dataSource = new YAHOO.util.DataSource('/someUrl'); dataSource.responseType = YAHOO.util.DataSource.TYPE_JSON; dataSource.connXhrMode = 'queueRequests'; dataSource.responseSchema = { resultsList: 'results', fields: [ {key: 'foo'}, {key: 'bar'}, {key: 'baz'} ] }; var dataTable = new YAHOO.widget.DataTable('container', columns, dataSource); var callback = function() { success: dataTable.onDataReturnReplaceRows, failure: function() { // error handling code }, scope: dataTable }; dataSource.setInterval(1000, null, callback); And here's what I'd like to do with it: dataTable.subscribe('cellUpdateEvent', function(record, column, oldData) { var td = dataTable.getTdEl({record: record, column: column}); YAHOO.util.Dom.setStyle(td, 'backgroundColor', '#ffff00'); var animation = new YAHOO.util.ColorAnim(td, { backgroundColor: { to: '#ffffff'; } }); animation.animate(); }; However, it doesn't seem like using cellUpdateEvent works. Does a cell that's updated as a result of the setInterval callback even fire a cellUpdateEvent? It may be that I don't fully understand what's going on under the hood with DataTable. Perhaps the whole table is being redrawn every time the data is queried, so it doesn't know or care about changes to individual cells?. Is the solution to write my own specific function to replace onDataReturnReplaceRows? Could someone enlighten me on how I might go about accomplishing this? Edit: After digging through datatable-debug.js, it looks like onDataReturnReplaceRows won't fire the cellUpdateEvent. It calls reset() on the RecordSet that's backing the DataTable, which deletes all of the rows; it then re-populates the table with fresh data. I tried changing it to use onDataReturnUpdateRows, but that doesn't seem to work either.

• JSONP request using jquery $.getJSON not working on well formed JSON.

  - by Antti

  I'm not sure is it possible now from the url I am trying. Please see this url: http://www.heiaheia.com/voimakaksikko/stats.json It always serves the same padding function "voimakaksikkoStats". It is well formed JSON, but I have not been able to load it from remote server. Does it need some work from the server side or can it be loaded with javascript? I think the problems gotta to have something to with that callback function... JQuery is not requirement, but it would be nice. This (callback=voimakaksikkoStats) returns nothing (firebug - net - response), and alert doesn't fire: $.getJSON("http://www.heiaheia.com/voimakaksikko/stats.json?callback=voimakaksikkoStats", function(data){ alert(data); }) but this (callback=?): $.getJSON("http://www.heiaheia.com/voimakaksikko/stats.json?callback=?", function(data){ alert(data); }) returns: voimakaksikkoStats({"Top5Sports":[],"Top5Tests":{"8":"No-exercise ennuste","1":"Painoindeksi","2":"Vy\u00f6t\u00e4r\u00f6n ymp\u00e4rys","10":"Cooperin testi","4":"Etunojapunnerrus"},"Top5CitiesByTests":[],"Top5CitiesByExercises":[],"ExercisesLogged":0,"Top5CitiesByUsers":[""],"TestsTaken":22,"RegisteredUsers":1}); But I cannot access it... In both examples the alert never fires. Can someone help?

• Passing object(s) to a Controller Action

  - by Nicholas H

  I'm attempting to use jQuery to do a $.post() to an MVC controller action. Here's the jQuery calls: var _authTicket = { username: 'testingu', password: 'testingp' }; function DoPost() { var inputObj = { authTicket: _authTicket, dateRange: 'ThisWeek' }; $.post('/MyController/MyAction', inputObj, PostResult); } function PostResult(data) { alert(JSON.stringify(data)); } Here's the controller action: <HttpPost()> _ Function MyAction(ByVal authTicket As AuthTicket, ByVal dateRange As String) As ActionResult Dim u = ValidateUser(authTicket) If u Is Nothing Then Throw New Exception("User not valid") ' etc.. End Function The problem is, MyAction's "authTicket" parameter is all empty. The second "dateRange" parameter gets populated just fine. I'm pretty sure that the issue stems from jQuery turning the data into key/value pairs to POST to the action. MVC must not understand the format, at least when it's an object with it's own properties. The name/value pair format that jQuery is converting to is like: authTicket[username] = "testingu" authTicket[password] = "testingp" Which in turn gets made into x-www-form-urlencoded'd data: authTicket%5Busername%5D=testingu &authTicket%5Bpassword%5D=testingp I guess I could always have "username" and "password" properties in my actions, but that seems wrong to me. Any help would be appreciated.

I have some code here which works perfectly in firefox but not in chrome or IE, my javascript is thus ` $(document).ready(function() { $("#clientLoginPop").show(); $("#clientLoginPop").animate({"left": "-=400px"}, "fast"); }); $("#clientLoginCloseLink").click(function () { $("#clientLoginPop").animate({"left": "+=400px"}, "fast"); }); $("#contactUsPopLink").click(function () { $("#contactUsPop").show(); $("#contactUsPop").animate({"left": "-=437px"}, "fast"); }); $("#contactUsClose").click(function () { $("#contactUsPop").animate({"left": "+=474px"}, "fast"); }); }); ` and finally the css of the div looks like this, i think rather importantly it's aligned to the right of the browser: (the client login div looks similar just a different height) ` #contactUsPop { width:437px; right:-437px; margin-top:220px; position:fixed; height:217px; background-color:white; z-index:2; } ` so what happens in firefox is the div animates to the left and then when it closes it moves back to the right. when in chrome the div doesn't seem to pop up at all? the URL of the site is this: http://clearcreativegroup.com/devcorner/clear3/ the tabs are on the right hand side of the browser, any advice would help tons, thank you!

• php xpath problems

  - by Phill Pafford

  I'm doing a cURL POST and get the error response back, parse it into an array but having issues with xpath now. // XML <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <errors xmlns="http://host/project"> <error code="30" description="[] is not a valid email address."/> <error code="12" description="id[] does not exist."/> <error code="3" description="account[] does not exist."/> <error code="400" description="phone[] does not exist."/> </errors> // Function / Class class parseXML { protected $xml; public function __construct($xml) { if(is_file($xml)) { $this->xml = simplexml_load_file($xml); } else { $this->xml = simplexml_load_string($xml); } } public function getErrorMessage() { $in_arr = false; $el = $this->xml->xpath("//@errors"); $returned_errors = count($el); if($returned_errors > 0) { foreach($el as $element) { if(is_object($element) || is_array($element)) { foreach($element as $item) { $in_arr[] = $item; } } } } else { return $returned_errors; } return $in_arr; } } // Calling function // $errorMessage is holding the XML value in an array index // something like: $arr[3] = $xml; $errMsg = new parseXML($arr[3]); $errMsgArr = $errMsg->getErrorMessage(); What I would like is all the error code and description attribute values

• Resizing image algorithm in python

  - by hippocampus

  So, I'm learning my self python by this tutorial and I'm stuck with exercise number 13 which says: Write a function to uniformly shrink or enlarge an image. Your function should take an image along with a scaling factor. To shrink the image the scale factor should be between 0 and 1 to enlarge the image the scaling factor should be greater than 1. This is not meant as a question about PIL, but to ask which algorithm to use so I can code it myself. I've found some similar questions like this, but I dunno how to translate this into python. Any help would be appreciated. I've come to this: import image win = image.ImageWin() img = image.Image("cy.png") factor = 2 W = img.getWidth() H = img.getHeight() newW = int(W*factor) newH = int(H*factor) newImage = image.EmptyImage(newW, newH) for col in range(newW): for row in range(newH): p = img.getPixel(col,row) newImage.setPixel(col*factor,row*factor,p) newImage.draw(win) win.exitonclick() I should do this in a function, but this doesn't matter right now. Arguments for function would be (image, factor). You can try it on OP tutorial in ActiveCode. It makes a stretched image with empty columns :.

• Reading from serial port with Boost Asio?

  - by trikri

  Hi! I'm going to check for incoming messages (data packages) on the serial port, using Boost Asio. Each message will start with a header that is one byte long, and will specify which type of the message has been sent. Each different type of message has an own length. The function I'm about to write should check for new incoming messages continually, and when it finds one it should read it, and then some other function should parse it. I thought that the code might look something like this: void check_for_incoming_messages() { boost::asio::streambuf response; boost::system::error_code error; std::string s1, s2; if (boost::asio::read(port, response, boost::asio::transfer_at_least(0), error)) { s1 = streambuf_to_string(response); int msg_code = s1[0]; if (msg_code < 0 || msg_code >= NUM_MESSAGES) { // Handle error, invalid message header } if (boost::asio::read(port, response, boost::asio::transfer_at_least(message_lengths[msg_code]-s1.length()), error)) { s2 = streambuf_to_string(response); // Handle the content of s1 and s2 } else if (error != boost::asio::error::eof) { throw boost::system::system_error(error); } } else if (error != boost::asio::error::eof) { throw boost::system::system_error(error); } } Is boost::asio::streambuf is the right thing to use? And how do I extract the data from it so I can parse the message? I also want to know if I need to have a separate thread which only calls this function, so that it get called more often? Isn't there a risk for loosing data in between two calls to the function otherwise, because so much data comes in that it can't be stored in the serial ports memory? I'm using Qt as a widget toolkit and I don't really know how long time it needs to process all it's events.

• calling Valums Ajax uploader from other DOM element

  - by Marc

  I'm facing a problem with the valums Ajax File upload. Since the plugin is working perfectly after a few modifications on the server side, I cannot implement a specific behavior. My DOM is composed with an input file plus the container to instantiate the fileuploader buttons. What I want is to be able to fire the fileuploader plugins when clicking on the input:file[name="upload-file"]. ... <div id="upload-accepted"> <fieldset> <label for="upload-file">Select a file:</label> <input type="file" name="upload-file" id="upload-file"/> <noscript> <p>Please enable JavaScript to use file uploader.</p> </noscript> </fieldset> <div id="upload-container"> </div> </div> ... <script type="text/javascript"> $(function() { var uploader = new qq.FileUploader({ action: '/file-upload', element: document.getElementById('upload-container'), onSubmit: function(id, filename){...}, onComplete: function(id, fileName, responseJSON){...} }); }); </script> I have tried to add the following on the script but it don't works $("#upload-file").live('change', function(event) { event.preventDefault(); $('.qq-upload-button').trigger('click'); return false; }); Any clues? Thanks in advance!

• Facebook JS API: How to get FB.Connect.streamPublish to use auto_publish

  - by Prody

  I'm trying to publish stuff to someone's wall. It works, but I'm also trying to use the auto_publish feature so the user will only get one popup granting the publish_stream extended permission. So I set streamPublish's auto_publish to true, but I still get the popup asking me if I want to publish and/or edit the message. What am I doing wrong? Here's what I'm running: FB.ensureInit(function () { FB.Facebook.get_sessionState().waitUntilReady(function() { FB.Connect.showPermissionDialog("publish_stream", function(perms) { if (perms == "publish_stream") { FB.Facebook.apiClient.friends_get(null, function(result) { var markup = ""; var targets = result; targets = [testFriendsIDForTesting]; var attachment = { name: "Blablabla", href: window.location.href, description: "description", caption: "caption" }; var actionLinks = [{ text: "View", href: window.location.href }]; var num_targets = targets.length; for (var i=0; i<num_targets; i++) { var fId = targets[i]; FB.Connect.streamPublish("none", attachment, actionLinks, fId, "none", null, false); } }); } }); }); });
