  • HP QTP 10: Web-app testing - SomeObj.FireEvent("OnCLick") works, SomeObj.Object.FireEvent("OnCLick") doesn't

    - by Vitaliy
    Hi all! I have rich web app btuil with ExtJS. It has multi-select list control (created with JS+CSS). I want to click on some item in that list using HP QuickTest Pro 10 with Internet Explorer 6. I added that item into Object repository and found that following code works - selects some item: Browser("blah").Page("blah").WebElement("SomeElem").Click next code also works: Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseDown") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseUp") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onClick") But I want to select several items using shift+click method. I don't know to do that :( So I have a few questions: How can perform click with mouse on several web elements with Shift key pressed? I tried to do that using CreateEventObject + shiftKey set to true, but the method (perform fireEvent on DOM object, not object from Object repository) doesn't work: Browser("blah").Page("blah").WebElement("SomeElem").Object.FireEvent("onClick") What the difference between WebElement("Element").FireEvent("OnClick") and WebElement("Element").Object.FireEvent("OnClick") ? Plsease, help someone, because I fought with that problem a lot, but had no result. Thanks!

  • CSS / jQuery Vertically and Horizontally Center DIV

    - by aherrick
    I'm trying to vertically and horizontally center this div even when there is content to scroll and the user is scrolling down the page. The following test works fine in IE, but in Firefox I get a weird flickering affect when hovering over the thumbnail image. Any thoughts? <html> <head> <title>aj</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(function() { // img preview $('.img').hover(function() { if (!$('#overlay').length) { $('<div id="overlay"/>').css({ position: 'fixed', top: 0, left: 0, width: '100%', zIndex: 100, height: $(window).height() + 'px' }).appendTo('body'); $('<div id="item" />').css({ border: '7px solid #999', height: '500px', width: '500px', top: '50%', left: '50%', position: 'absolute', marginTop: '-250px', marginLeft: '-250px' }).append('<img src="' + $(this).attr('rel') + '" alt="img" />').appendTo('#overlay'); } }, function() { $('#overlay').remove(); }); }); </script> </head> <body> <img class="img" src="http://ajondeck.net/temp/paperboy_thumb.gif" rel="http://ajondeck.net/temp/paperboy.gif" alt="image" /> </body> </html>

  • Can I create template-based library objects in Dreamweaver CS5?

    - by Danjah
    At work we need two 'streams' of template. The first are general layout templates, like the ones already available in the MX through CS5 packages (except we'd have our own customised ones). The second are more granular objects, some of which are functional. In both cases, I don't want Jimmy to be able to wreak havoc inside anything other than the 'editable regions' which make up the templates. Now this is fine if I stick with the first scenario (layout templates) where there's simply a big chunk of editable region for good ole Jim to sprawl into, think of this as the 'body content' area. But I really do need these granular library (or snippet) objects to work in the same way. Unfortunately with my attempts so far they don't work as I'd have thought - perhaps for good reason? When I create a blank template and throw in my chunk of HTML (unobstrusive JS and external CSS use selectors in this HTML to provide style and function) and save it as a new library item or snippet, all looks well. Then I create a new document based on a layout template and save it as a plain html file (still all good so far). Next I drop in my custom library item... still all good... but then I go to save the document and it only allows me to save it as a new template! I expected it would just allow me to save it as HTML and have it simply respect the defined editable regions, as happens in the containing page 'body content' editable region. Apologies if that got specific and technical quite quickly, but it is quite particular. If you want some example files lemme know and I'll zip some up. Many thanks :) p.s It is not a requirement that library objects must somehow inject their dependency files into the newly created page - I already know what they'll be. Also, I know I must 'detatch from original' once I drop a library item into a document which then allows customisation of the library object.

  • Why can't I fade out this table row in IE using jQuery?

    - by George Edison
    I can't get the table row to fade out in IE. It works in Chrome, but not IE. It just becomes really 'light' and stays on the screen. I tried IE8 with and without compatibility mode. <html> <head> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> function hideIt() { $('#hideme').fadeTo("slow", 0.0); } </script> </head> <body> <table> <tr id='hideme'> <td>Hide me!</td> </tr> </table> <button onclick='hideIt();'>Hide</button> </body> </html> Is there a workaround/solution for a smooth fade?

  • Auto-resize custom horizontal scrollbar/slider?

    I'm working on a site that scrolls horizontally. I know very little about jQuery and prototype and I got this slider script working as the page scrollbar. When the window is resized smaller, the custom horizontal slider/scrollbar won't resize to the viewport's width. I have the page and js files here http://keanetix.co.cc/scrollpage/ Try to resize the browser and you'll notice the custom scrollbar extending to the right. The custom scrollbar wont fit on the viewport, unless you refresh the page when it's been resized. Can somebody help me with this? Thanks. This is the code in the HTML page: <script type="text/javascript" language="javascript"> // <![CDATA[ // horizontal slider control var slider2 = new Control.Slider('handle', 'track', { onSlide: function(v) { scrollHorizontal(v, $('scrollable'), slider2); }, onChange: function(v) { scrollHorizontal(v, $('scrollable'), slider2); } }); // scroll the element horizontally based on its width and the slider maximum value function scrollHorizontal(value, element, slider) { element.scrollLeft = Math.round(value/slider.maximum*(element.scrollWidth-element.offsetWidth)); } // disable horizontal scrolling if text doesn't overflow the div if ($('scrollable').scrollWidth <= $('scrollable').offsetWidth) { slider2.setDisabled(); $('track').hide(); } // ]]> </script>

  • How to set different width for INPUT and DIV elements with Scriptaculous Ajax.Autocompleter?

    - by Grzegorz Gierlik
    Hello, I am working on autocompleter box based on Scriptaculous Ajax.Autocompleter. Here how my HTML/JS code looks like: <input type="text" maxlength="255" class="input iSearchInput" name="isearch_value" id="isearch" value="<wl@txt>Search</wl@txt>" onfocus="this.select()"> <br> <div id='isearch_choices' class='iSearchChoices'></div> <script> function iSearchGetSelectedId(text, li) { console.log([text, li.innerHTML].join("\n")); document.location.href = li.getAttribute("url"); } document.observe('dom:loaded', function() { new Ajax.Autocompleter("isearch", "isearch_choices", "/url", { paramName: "phrase", minChars: 1, afterUpdateElement : iSearchGetSelectedId }); $("isearch_choices").setStyle({width: "320px"}); }); </script> and CSS classes: input.iSearchInput { width: 155px; height: 26px; margin-top: 7px; line-height: 20px; } div.iSearchChoices { position:absolute; background-color:white; border:1px solid #888; margin:0; padding:0; width: 320px; } It works in general, but I need to have list of choices wider then input box. My first try was to set various width with CSS classes (like above), but it didn't work -- list of choices became as wide as input box. According to Firebug width defined by my CSS class was overwritten by width set by element.style CSS class, which seems to be defined by Ajax.Autocompleter. My second try was to set width for list of choices after creating Ajax.Autocompleter $("isearch_choices").setStyle({width: "320px"}); but it didn't work too :(. No more ideas :(. How to set different width for list of choices for Scriptaculous Ajax.Autocompleter?

  • Getting Safari document title/location with Scripting Bridge does not work in full-screen mode

    - by Mark
    I'm trying to get the URL and document title from the topmost Safari document/tab. I have an AppleScript and an objective-c version using Apple's Scripting Bridge framework. Both versions work fine for most web pages, however when I open a Youtube video in full-screen mode, the Scripting Bridge based version fails. The Apple Script works fine for "normal" and full-screen Safari windows. Can anyone see what is wrong with the Scripting Bridge code below to cause it to fail for full-screen Safari windows? Here the code (I omitted error checking for brevity): AppleScript: tell application "Safari" # Give us some time to open video in full-screen mode delay 10 do JavaScript "document.title" in document 0 end tell Scripting Bridge: SafariApplication* safari = [SBApplication applicationWithBundleIdentifier:@"com.apple.Safari"]; SBElementArray* windows = [safari windows]; SafariTab* currentTab = [[windows objectAtIndex: 0] currentTab]; // This fails when in full-screen mode: id result = [safari doJavaScript: @"document.title" in: currentTab]; NSLog(@"title: %@", result); Scripting Bridge error (with added line breaks): Apple event returned an error. Event = 'sfri'\'dojs'{ '----':'utxt'("document.title"), 'dcnm':'obj '{ 'want':'prop', 'from':'obj '{ 'want':'cwin', 'from':'null'(), 'form':'indx', 'seld':1 }, 'form':'prop', 'seld':'cTab' } } Error info = { ErrorNumber = -1728; ErrorOffendingObject = <SBObject @0x175c2de0: currentTab of SafariWindow 0 of application "Safari" (238)>; } I could not find details about the given error code. It complains about 'currentTab' which shows that the JavaScript event at least made it all the way to Safari. I assume that the current tab receives the event, but refuses to run the JS code, because it is in full-screen mode. However, why does this work for an AppleScript? Don't they use the same code path eventually? Any suggestions are greatly appreciated. Thanks!

  • Passing two variables to separate table...associations problem

    - by bgadoci
    I have developed an application and I seem to be having some problems with my associations.

  • How to modify the style of jQuery DatePicker's disabled dates?

    - by Clay
    Given this page: http://jqueryui.com/demos/datepicker/#min-max And viewing its source: http://jqueryui.com/themeroller/css/parseTheme.css.php I can change the following line (using Chrome's inspect element feature) and see those changes reflected: .ui-state-disabled, .ui-widget-content .ui-state-disabled { opacity: .35; filter:Alpha(Opacity=35); background-image: none; } However, if I try to override my own test page with something like... .ui-state-disabled, .ui-widget-content .ui-state-disabled { opacity: .99 !important; filter:Alpha(Opacity=99) !important; background-image: none !important; color:Red !important; } ...I do not see my changes reflected in the calendar. I can make other changes in my own test page and those are reflected for other classes in the datepicker. So, I'm not having any kind of path issue to the .js or .css files. What am I missing here? UPDATE/SOLUTION Firebug to the rescue...this took care of my styling needs: .ui-datepicker-week-end{color: #c0c0c0 !important;} div#ui-datepicker-div.ui-datepicker{color: #c0c0c0;} div#ui-datepicker-div.ui-datepicker:hover{cursor: default important;} .ui-datepicker-calendar th{color: #222222 !important;}

  • jQuery RJS inserting string vs dom.

    - by Dmitriy Likhten
    So I am trying to use jQuery to insert data from an ajax call. I actually use the jquery.form plugin, and have the ajax form submitted with a dataType: 'script'. The response is a jquery expression which contains a <%= javascript_escape(render ...) %> erb tag (similar to what the railscasts episode 136 instructs to do). However the end result is that the full text of the render is inserted as if that was the content to be inserted into the page, as text, not as dom elements. Could the fact that the render had some newlines at the beginning be the cause? Dom text: "\n \n &lt;li>....&lt;/li>" I also tried having jQuery just read the response as a script and execute it, and used the prototype-based rjs stuff, same effect, the text is inserted into the dom. Are there any reasons why such a behavior would be experienced? A bit of clarification: My response.js.erb is jQuery("#content").append("<%= escape_javascript(render(:partial => "widgets")) %>"); jQuery("#information").text("Finally, something happened!"); The full text inside the append() call is inserted as text into #content.

  • [Google Maps] Trouble with invalid argument when switching jQueryUI based tabs

    - by Chad
    Here's a page with the issue To reproduce the error, using IE - click the directions tab, then any of the others. What I'm trying to do is this: On page load, do nothing really. However, when the directions tab loads - setup the map. Like so: $('#tabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "tabs-5") { // get map for directions var dirMap = new GMap2($("div#dirMap").get(0)); dirMap.setCenter(new GLatLng(35.79648921414565,139.40663874149323), 12); dirMap.enableScrollWheelZoom(); dirMap.addControl(new PanoMapTypeControl()); geocoder = new GClientGeocoder(); $("#dirMap").resizable({ stop: function() { dirMap.checkResize(); } }); // clear dirText $("div#dirMapText").html(""); dirMap.clearOverlays(); var polygon = new GPolygon([new GLatLng(35.724496338474104,139.3444061279297),new GLatLng(35.74748750802863,139.3363380432129),new GLatLng(35.75765724051559,139.34303283691406),new GLatLng(35.76545779822543,139.3418312072754),new GLatLng(35.767547103447725,139.3476676940918),new GLatLng(35.75835374997911,139.34955596923828),new GLatLng(35.755149755962755,139.3567657470703),new GLatLng(35.74679090345495,139.35796737670898),new GLatLng(35.74762682821177,139.36294555664062),new GLatLng(35.744422402303826,139.36346054077148),new GLatLng(35.74860206266584,139.36946868896484),new GLatLng(35.735644401200986,139.36843872070312),new GLatLng(35.73843117306677,139.36174392700195),new GLatLng(35.73592308277646,139.3531608581543),new GLatLng(35.72686543236113,139.35298919677734),new GLatLng(35.724496338474104,139.3444061279297)], "#f33f00", 5, 1, "#ff0000", 0.2);dirMap.addOverlay(polygon); // load directions directions = new GDirections(dirMap, $("div#dirMapText").get(0)); directions.load("from: [email protected],139.37083393335342 to: Ruby [email protected],139.40663874149323"); } }); What the heck is causing the error? The IE javascript debugger claims the error lies in main.js, line 139 character 28. (the google maps api file). Which is this line: function zf(a,b){a=a.style;a.width=b.getWidthString();a.height=b.getHeightString()} Any ideas? Thanks in advance!

  • sIFR - getting a:hover to work in navigation list

    - by HudRom
    Hi, I am currently struggling with sIFR and a:hover. My problem site is hosted at http://irene.huditsch.info I have the following HTML code: <body id="irene-huditsch-info"> <div id="header"> <h1>Irene Huditsch</h1> <div id="top-nav"> <ul> <li id="impressum"> <a href="impressum.html" rel="index">Impressum</a> </li> <li id="kontakt"> <a href="kontakt.html">Kontakt</a> </li> </ul> </div> ... My sIFR-config.js looks like: sIFR.replace(braganza, { selector: 'div#top-nav a', css: '.sIFR-root { background-color: transparent; color: #FFFFFF; line-height: 13px; font-size: 11px; text-decoration: underline; cursor: pointer; } .sIFR-root:hover { color: #592b02; }', wmode: 'transparent' }); But the hover doesn't take effect. I tried different solution with no success either. When I write sIFR.replace(braganza, { selector: 'div#top-nav li', css: 'a { background-color: transparent; color: #FFFFFF; line-height: 13px; font-size: 11px; text-decoration: underline; cursor: pointer; } a:hover { color: #592b02; }', wmode: 'transparent' }); (which seems logical to me), the list items are not rendered at all. Could you please give me an advice how to do it correctly with the structure given? Thanks, Roman

  • jQuery Tools alert works once (but only once)

    - by Jim Miller
    I'm trying to build a simple alert mechanism with jQuery Tools -- in response to a bit of Javascript code, pop up an overlay with a message and an OK button that, when clicked, makes the overlay go away. Trivial, or it should be. I've been slavishly following http://flowplayer.org/tools/demos/overlay/trigger.html, and have something that works fine the first time it's invoked, but only that time. If I repeat the JS action that should expose the overlay, it doesn't. My content/DIV: <div class='modal' id='the_alert'> <div id='modal_content' class='modal_content'> <h2>hi there</h2> this is the body <p> <button class='close'>OK</button> </p> </div> <div id='modal_background' class='modal_background'><img src='/images/overlay/f9f9f9-180.png' class='stretch' alt='' /></div> </div> and the Javascript: function showOverlayDialog() { $('#the_alert').overlay({ mask: {color: '#cccccc', loadSpeed: 200, opacity: 0.9}, closeOnClick: false, load: true }); } As I said: When showOverlayDialog() is invoked the first time, the overlay appears just like it should, and goes away when the "OK" button is clicked. But if I cause showOverlayDialog() to run again, without reloading the page, nothing happens. If I reload the page, then the pattern repeats -- the first invocation brings up the overlay, but the second one doesn't. I'm obviously missing something -- any advice out there? Thanks!

  • Retrieve click() handler in jQuery for later use

    - by Xiong Chiamiov
    I'm using the jQuery tablesorter plugin to sort a table, which assigns .click() handlers to the <th>s in the table. Since my table has alternating colors for each column, I've built a simple fix_table_colors(identifier) function that does as it should when I call it manually using Firebug. I would like, however, to have that automatically called after a sort. To do this, I decided to retrieve the .click() handler from the <th>s, and assign a new handler that simply calls the previous handler, followed by fix_table_colors(). (This SO question is similar, but uses standard onClick() attributes, which won't work here.) From the accepted answer to this question, I have created the following code: $(document).ready(function() { $("table.torrents").tablesorter({ debug: true, headers: { 1: { sorter: 'name' }, 2: { sorter: 'peers' }, 3: { sorter: 'filesize' }, 4: { sorter: 'filesize' }, 5: { sorter: 'filesize' }, 6: { sorter: 'ratio' } } }); $('table.torrents thead th').each(function() { var th = $(this); var clickHandler = th.data('events').click[0]; th.click(function() { clickHandler(); fix_table_colors('table.torrents'); }); }); }); While this is conceptually correct, clickHandler doesn't appear to actually be a function, and so I cannot call it. With a bit more digging in Firebug, I found that click[3] appears to hold the function I'm looking for (and click[10] my new one). I get an 'e is undefined' error on line 2 of tablesorter.min.js when using that, though. Am I even going down the right path? I have a feeling that with what I've found so far, I can make this work, but it's going to be much uglier than I would expect it needs to be.

  • img onload doesn't work well in IE7

    - by rmeador
    I have an img tag in my webapp that uses the onload handler to resize the image: <img onLoad="SizeImage(this);" src="foo" > This works fine in Firefox 3, but fails in IE7 because the image object being passed to the SizeImage() function has a width and height of 0 for some reason -- maybe IE calls the function before it finishes loading?. In researching this, I have discovered that other people have had this same problem with IE. I have also discovered that this isn't valid HTML 4. This is our doctype, so I don't know if it's valid or not: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Is there a reasonable solution for resizing an image as it is loaded, preferably one that is standards-compliant? The image is being used for the user to upload a photo of themselves, which can be nearly any size, and we want to display it at a maximum of 150x150. If your solution is to resize the image server-side on upload, I know that is the correct solution, but I am forbidden from implementing it :( It must be done client side, and it must be done on display. Thanks. Edit: Due to the structure of our app, it is impractical (bordering on impossible) to run this script in the document's onload. I can only reasonably edit the image tag and the code near it (for instance I could add a <script> right below it). Also, we already have Prototype and EXT JS libraries... management would prefer to not have to add another (some answers have suggested jQuery). If this can be solved using those frameworks, that would be great. Edit 2: Unfortunately, we must support Firefox 3, IE 6 and IE 7. It is desirable to support all Webkit-based browsers as well, but as our site doesn't currently support them, we can tolerate solutions that only work in the Big 3.

  • Javascript: prototypeal inheritance and the prototype proprity

    - by JanD
    Hi, I have a simple code fragment in JS working with prototype inheritance. function object(o) { function F() {} F.prototype = o; return new F(); } //the following code block has a alternate version var mammal={ color: "brown", getColor: function(){ return this.color; } } var myCat = object(mammal); myCat.meow = function(){return "meow";} that worked fine but adding this: mammal.prototype.kindOf = "predator"; does not. ("mammal.prototype is undefined") Since I guessed that object maybe have no prototype I rewrote it, replacing the var mammal={... block with: function mammal(){ this.color="brown"; this.getColor = function(){return this.color;} } which gave me a bunch of other errors: "Function.prototype.toString called on incompatible object" and if I try to call _myCat.getColor() "myCat.getColor is not a function" Now I am totally confused. After reading Crockford, and Flanagan I did not get the solution for the errors. So it would be great if somebody knows... - why is the prototype undefined in the first example (which is foremost concern; I thought the prototype of explicitly set in the object() function) - why get I these strange errors trying to use the mammal function as prototype object in the object() function?

I have the code below live here! <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Radio Button jQuery Change</title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> console.log("parsed"); $("input[name='rdio']").change(function() { console.log("changed"); if ($("input[name='rdio']:checked").val() == 'a') $("output").text("a changed"); else if ($("input[name='rdio']:checked").val() == 'b') $("output").text("b changed"); else $("output").text("c changed"); }); </script> </head> <body> <div> <input type="radio" name="rdio" value="a" checked="checked" /> a <br/> <input type="radio" name="rdio" value="b" /> b <br/> <input type="radio" name="rdio" value="c" /> c </div> <h3>Output:</h3> <div id="output"></div> </body> </html> Can anyone see what I've missed? Thanks, Denis

  • How to access CSS generated content with JavaScript

    - by Boldewyn
    I generate the numbering of my headers and figures with CSS's counter and content properties: img.figure:after { counter-increment: figure; content: "Fig. " counter(section) "." counter(figure); } This (appropriate browser assumed) gives a nice labelling "Fig. 1.1", "Fig. 1.2" and so on following any image. Question: How can I access this from Javascript? The question is twofold in that I'd like to access either the current value of a certain counter (at a certain DOM node) or the value of the CSS generated content (at a certain DOM node) or, obviously, both information. Background: I'd like to append to links back-referencing to figures the appropriate number, like this: <a href="#fig1">see here</h> ------------------------^ " (Fig 1.1)" inserted via JS As far as I can see, it boils down to this problem: I could access content or counter via getComputedStyle: var fig_content = window.getComputedStyle( document.getElementById('fig-a'), ':after').content; However, this is not the live value, but the one declared in the stylesheet. I cannot find any interface to access the real live value.

  • Send form when hitting enter

    - by Álvaro G. Vicario
    I have a form in a jQuery enabled site. The form does not feature an <input type="submit"> button. For that reason, it's not submitted when you hit enter. What's the recommended way to emulate such behaviour? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head><title></title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"><!-- $(function(){ $("form input:first").focus(); }); //--></script> </head> <body> <form action="" method="post"> <input type="text" name="user"> <input type="password" name="pass"> </form> </body> </html>

  • How can CSS be applied to components from Google Closure Library?

    - by Jason
    I'm getting my feet wet with Google's Closure Library. I've created a simple page with a Select Widget, but it clearly needs some styling (element looks like plain text, and in the example below the menu items pop up beneath the button). I'm assuming the library supports styles -- how can I hook into them? Each example page in SVN seems to use its own CSS. Abbreviated example follows: <body> <div id="inputContainer"></div> <script src="closure-library-read-only/closure/goog/base.js"></script> <script> goog.require('goog.dom'); goog.require('goog.ui.Button'); goog.require('goog.ui.MenuItem'); goog.require('goog.ui.Select'); </script> <script> var inputDiv = goog.dom.$("inputContainer"); var testSelect = new goog.ui.Select("Test selector"); testSelect.addItem(new goog.ui.MenuItem("1")); testSelect.addItem(new goog.ui.MenuItem("2")); testSelect.addItem(new goog.ui.MenuItem("3")); var submitButton = new goog.ui.Button("Go"); testSelect.render(inputDiv); submitButton.render(inputDiv); </script> </body>

  • Javascript: prototypal inheritance and the prototype property

    - by JanD
    Hi, I have a simple code fragment in JS working with prototype inheritance. function object(o) { function F() {} F.prototype = o; return new F(); } //the following code block has a alternate version var mammal = { color: "brown", getColor: function() { return this.color; } } var myCat = object(mammal); myCat.meow = function(){return "meow";} that worked fine but adding this: mammal.prototype.kindOf = "predator"; does not. ("mammal.prototype is undefined") Since I guessed that object maybe have no prototype I rewrote it, replacing the var mammal={... block with: function mammal() { this.color = "brown"; this.getColor = function() { return this.color; } } which gave me a bunch of other errors: "Function.prototype.toString called on incompatible object" and if I try to call _myCat.getColor() "myCat.getColor is not a function" Now I am totally confused. After reading Crockford, and Flanagan I did not get the solution for the errors. So it would be great if somebody knows... - why is the prototype undefined in the first example (which is foremost concern; I thought the prototype of explicitly set in the object() function) - why get I these strange errors trying to use the mammal function as prototype object in the object() function? Edit by the Creator of the Question: These two links helped a lot too: Prototypes_in_JavaScript on the spheredev wiki explains the way the prototype property works relativily simple. What it lacks is some try-out code examples. Some good examples are provided by Morris John's Article. I personally find the explanations are not that easy as in the first link, but still very good. The most difficult part even after I actually got it is really not to confuse the .prototype propery with the internal [[Prototype]] of an object.

  • Problem Parsing JSON Result with jQuery

    - by senfo
    I am attempting to parse JSON using jQuery and I'm running into issues. In the code below, I'm using a static file, but I've also tested using an actual URL. For some reason, the data keeps coming back as null: <!DOCTYPE html> <html> <head> <title>JSON Test</title> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $.getJSON('results.json', function(data) { alert(data); // Result is always null }); </script> </head> <body> </body> </html> The JSON results look like the following: {"title":"HEALTHPOINT TYEE CAMPUS","link":"http://www.healthpointchc.org","id":"tag:datawarehouse.hrsa.gov,2010-04-29:/8357","org":"HEALTHPOINT TYEE CAMPUS","address":{"street-address":"4424 S. 188TH St.","locality":"Seatac","region":"Washington","postal-code":"98188-5028"},"tel":"206-444-7746","category":"Service Delivery Site","location":"47.4344818181818 -122.277672727273","update":"2010-04-28T00:00:00-05:00"} If I replace my URL with the Flickr API URL (http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?), I get back a valid JSON result that I am able to make use of. I have successfully validated my JSON at JSONLint, so I've run out of ideas as to what I might be doing wrong. Any thoughts?

  • How to get around the event bubble using jQuery's: .live()

    - by Nick
    Hi there. Here is the code in question: $(".navItems>ul>li").live('click', function(){ var selectorID = $(this).attr('id'); $(".infoList").slideUp('fast', function(){ switchTabInfo(selectorID); }); function switchTabInfo(selectorID){ var actionID = selectorID.substring(4); actionID = "#" + actionID; $(actionID).slideDown(); } So in short i have a these .infoList classes with id names tied to back to the nav li id. That lists item's id might be nav_testsHistory for example. With all the content boxes hidden by class name this javascript makes a pleasing slide up, down effect. But the third content box flickers as will the second one after a third box push. It slides up and down a second unnecessary time. If I add an alert like this: $(".navItems>ul>li").live('click', function(){ var selectorID = $(this).attr('id'); $(".infoList").slideUp('fast', function(){ switchTabInfo(selectorID); alert('bubble'); }); The alert fires 3 times?! So my research took to reading about the event bubble. What I cannot find is how to check if it has been fired. I have not tried setting an input val and doing a tf test around the nested slider action. Cause that's crude. More info, all the code above is in a function, which is in an init() function, which is called on document ready. That's the only js file besides jquery 1.3.2. What do you guys think?
