  • jquery - Getting the second level parent of an element

    - by j-man86
    I am trying to retrieve the parent of an element's parent (grandparent?). I want to find that grandparent, then find a tag in that element, then store that text as a variable to publish elsewhere on the page. I've been trying to use the parent() function but without success. Here's the code I tried: $('.mixPlayCell a').click( function() { var title = $(this).parent().get(0).parent().get(0).text(); alert(title); }); Thanks!

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>

  • What's the correct type to use for pointer subtraction on x64?

    - by Cheeso
    I'm just starting out with x64 compilation. I have a couple of char*'s, and I'm subtracting them. With a 32-bit compile, this works: char * p1 = .... char * p3 = ... int delta = p3 - p1; But if I compile for x64 I get a warning: warning C4244: 'initializing' : conversion from '__int64' to 'int', possible loss of data What is the correct type to use, to represent a difference between two pointers, that works in both x86 and x64 compiles?

  • Retrieving information with Python's urllib from a page that is done via __doPostBack()?

    - by Omar
    I'm trying to parse a page that has different sections that are loaded with a Javascript __doPostBack() function. An example of a link is: javascript:__doPostBack('ctl00$cphMain$ucOemSchPicker$dlSch$ctl03$btnSch','') As soon as this is clicked, the browser doesn't fetch a new URL but a section of webpage is updated to reflect new information. What would I pass into a urllib function to complete the operation?

  • color letters in a div

    - by Growler
    I've created a palindrome checker. I want to take it one step further and show the letters being compared as it is being checked. HTML: <p id="typing"></p> <input type="text" id="textBox" onkeyup="pal(this.value);" value="" /> <div id="response"></div> <hr> <div id="palindromeRun"></div> JS: To do this, I run the recursive check... Then if it is a palindrome, I run colorLetters(), which I'm trying to highlight in green each letter as it is being checked. Right now it is just rewriting palindromeRun's HTML with the first letter. I know this is because of the way I'm resetting its HTML. I don't know how to just grab the first and last letter, change only those letters' css, then increment i and j on the next setTimeout loop. var timeout2 = null; function pal (input) { var str = input.replace(/\s/g, ''); var str2 = str.replace(/\W/, ''); if (checkPal(str2, 0, str2.length-1)) { $("#textBox").css({"color" : "green"}); $("#response").html(input + " is a palindrome"); $("#palindromeRun").html(input); colorLetters(str2, 0, str2.length-1); } else { $("#textBox").css({"color" : "red"}); $("#response").html(input + " is not a palindrome"); } if (input.length <= 0) { $("#response").html(""); $("#textBox").css({"color" : "black"}); } } function checkPal (input, i, j) { if (input.length <= 1) { return false; } if (i === j || ((j-i) == 1 && input.charAt(i) === input.charAt(j))) { return true; } else { if (input.charAt(i).toLowerCase() === input.charAt(j).toLowerCase()) { return checkPal(input, ++i, --j); } else { return false; } } } function colorLetters(myinput, i, j) { if (timeout2 == null) { timeout2 = setTimeout(function () { console.log("called"); var firstLetter = $("#palindromeRun").html(myinput.charAt(i)) var secondLetter = $("#palindromeRun").html(myinput.charAt(j)) $(firstLetter).css({"color" : "red"}); $(secondLetter).css({"color" : "green"}); i++; j++; timeout2=null; }, 1000); } } Secondary: If possible, I'd just like to have it colors the letters as the user is typing... I realize this will require a setTimeout on each keyup, but also am not sure how to write this.

  • Basic framework for presentations using HTML5 + javascript

    - by Brian C
    Do you know a framework for making presentations using only HTML5 and javascript technologies? I'm not talking about "export" features of various presentation software (powerpoint or OOo presentation). Some requirements for the presentations made with this "framework": take advantage of the latest HTML5 features (audio, video, canvas?) same with CSS3 (font support, gradient, shadows, transitions and transformations) If there's no such thing, example of good presentations or pointers on the subject would be appreciated.

  • How do I integrate a BSDF into a ray caster.

    - by pelb
    I'm trying to implement sub surface scattering at isosurfaces and looked up how a BSDF works mathematically. Implementing the reflective and diffuse part seems to be quite easy as i just have to evaluate phong at the isosurface intersection, but how do you I apply the transmissive part of the BSDF? In what way do i have to modify the ray direction. Any pointers to a practical implementation are welcome. Thanks and So long!

  • iphone sdk: autorotate jumps back up the page, showing information that has already been read...

    - by jonathan
    Hi, I am using - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{ return YES; } to allow rotation, which works fine - except that the landscape view jumps backwards up the page that is being displayed. I can't figure out what I should be looking at to fix it. I just want the page to rotate where it is. Any pointers would be great. Am a noob, as is probably clear. Thanks Jonathan

  • In Android OS or Java, what's the difference between a character sequence and a string????

    - by K-RAN
    For the API (Android SDK API version 8) functions whose definitions list character sequence parameters, I can feed the function String instead. Best part is that they work the same way, no hassle, no warnings. Is there a difference between the two types? And more importantly, is there an inherent danger if I send the function a String instead of a character sequence??? Thanks for any clarifications!!! :D

  • How many registers in custom VM?

    - by DeadMG
    I'm designing a custom VM and am curious about how many registers I should use. Initially, I had 255, but I'm a little concerned about backing 255 pointers (a whole KB) on to the stack or heap every time I call a function, when most of them won't even be used. How many registers should I use?

  • jQuery - Sorting an array?

    - by Probocop
    Hi, I'm using Ajax to get some XML, and then filling in some fields on a form with the results. There is a numerical field on the form and I would like to sort the results by this number (highest first). How would I go about doing this in jQuery? My js function code is currently: function linkCounts() { ws_url = "http://archreport.epiphanydev2.co.uk/worker.php?query=linkcounts&domain="+$('#hidden_the_domain').val(); $.ajax({ type: "GET", url: ws_url, dataType: "xml", success: function(xmlIn){ results = xmlIn.getElementsByTagName("URL"); for ( var i = 0; i < results.length; i++ ) { $("#tb_domain_linkcount_url_"+(i+1)).val($(results[i].getElementsByTagName("Page")).text()); $("#tb_domain_linkcount_num_"+(i+1)).val($(results[i].getElementsByTagName("Links")).text()); } $('#img_linkcount_worked').attr("src","/images/worked.jpg"); }, error: function(){$('#img_linkcount_worked').attr("src","/images/failed.jpg");} }); } The Links tag is the one I'm wanting to sort it on. Thanks For reference the XML that's getting returned is like the following: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <Response> <ResponseCode>1</ResponseCode> <ResponseStatus>OK</ResponseStatus> <ReportId>2</ReportId> <UrlChecked /> <MaxLinks>75</MaxLinks> <PagesFound>121</PagesFound> <URLs> <URL> <Page>http://www.epiphanysolutions.co.uk/blog</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/page/2/</Page> <Links>78</Links> </URL> </URLS> </Response>

  • using jQuery $get to pull data

    - by sadhu_
    Hi, I am trying to send a date to the server as part of a get transaction, however, looking at the urls (through firebug), it appears that the var sDate is never replaced with its value. Sorry i'm very new to JS and Jquery, so this is likely a very elementary mistake - i'm guessing it has something to do with the map that i am trying to pass to $.get? function drawVisualization(sDate, eDate) { alert(sDate + eDate); $.get( "http://localhost:8080/", "{'start':sDate}", function(data) { alert(data); }, "html" );

  • How can I hash a string to an int using c++?

    - by zebraman
    I have to write my own hash function. If I wanted to just make the simple hash function that maps each letter in the string to a numerical value (i.e. a=1, b=2, c=3, ...), is there a way I can perform this hash on a string without having to first convert it to a c-string to look at each individual char? Is there a more efficient way of hashing strings?
