  • Prototype Element.remove() not working in IE

    - by Gonçalo Queirós
    Hi there. I have a javascript function that gets a DIV by an ID and makes a clone. Then, removes the original DIV from DOM and inserts the cloned object..Everything works fine, except in IE, because the original DIV is never removed... var loadingDiv = $(Sybil.conf.loadingDivId), loadingClone = loadingDiv.clone(true); console.log($$('.loadingImg')); loadingDiv.remove(); //Insert the loading div on the page again elt.insert({after: loadingClone}); [loadingClone].invoke(func); console.log($$('.loadingImg')); The div also has a span inside with the class "loadingImg", so i just used the console.log to check how many elements there are. FF always prints [span.loadingImg] but IE prints [span.loadingImg,span.loadingImg] on the second console.log... Any idea of what might be happening? Thanks

  • Haskell search an element on a List

    - by user1887556
    I want a function that changes (1 to 0) on a list, when number of 1's isn't even. I have done these functions: 1) Sees if the lines in a list are even or not: parityLine :: [[Int]] -> [Bool] parityLine [] =[] parityLine (x:xs) |sum(x) `mod` 2 == 0 = True:(parityLine(xs)) |otherwise = False:(parityLine(xs)) 2) Sum the corresponding elements on a list of lists: sumPositions :: [[Int]] -> [Int] sumPositions [] = [] sumPositions (x:xs) = foldl (zipWith (+)) (repeat 0) (x:xs) 3) Sees if the columns in a list are even or not: parityColumn :: [Int] -> [Bool] parityColumn [] = [] parityColumn (x:xs) |head(x:xs) `mod` 2 == 0 = True:parityColumn(xs) |otherwise = False:parityColumn(xs) 4) Does the operation or with two boolean lists: bol :: [Bool] -> [Bool] -> [[Bool]] bol [] _ = [] bol (x:xs) (y:ys)= (map (||x) (y:ys)):(bol xs (y:ys)) 5) Correct List: correct :: [[Int]] -> [[Bool]] correct [] = [] correct (x:xs)=(bol(parityLine (x:xs))(parityColumn(sumPositions(x:xs)))) So what I want is to alter the function correct to [[Int]]-[[Int]] that does this: My Int list(x:xs) With my correct function applied [[0,0,1,1], [[True,True,False,True], [1,0,1,1], [True,True,True,True], [0,1,0,1], [True,True,True,True] [1,1,1,1]] [True,True,True,True]] Now I can see that in the first line third column, False, so I have to correct that number 1 to have a number of 1's even. Result I want that function correct does: [[0,0,0,1], [1,0,1,1], [0,1,0,1], [1,1,1,1]] Thanks.

  • Deselecting an element in jQuery

    - by Michael Itzoe
    I have a collection of span elements. In the code I have a global variable that represents the "selected" object. Using the click event when a span is clicked I reset the object's class, reset the global variable, then set the object to the variable and change its class (to make it "highlighted"). This effectively toggles selection when clicking an object. var currentItem = null; $( ".item" ).click( function() { if( $( this ).hasClass( "selected" ) ) { $( this ).removeClass( "selected" ) currentItem = null; } else { if( $( ".item" ).hasClass( "selected" ) ){ $( ".item" ).removeClass( "selected" ) } $( this ).addClass( "selected" ); currentItem = $( this ); } } ); What I'd like to be able to do is unselect when clicking on an empty area of the page. I tried creating a click event on the body object, but that overrode the span click event so nothing was selected. I'm a complete jQuery noob and not sure where to go with this.

  • jQuery : how to apply effect on a child element

    - by Tristan
    Hello, instead of re-writting the same function, i want to optimise my code : <div class="header"> <h3>How to use the widget</h3> <span id="idwidget" ></span> </div> <div class="content" id="widget"> the JS : <script type="text/javascript"> $(document).ready(function() { var showText="Show"; var hideText="Hide"; $("#idwidget").before("<a href='#' class='button' id='toggle_link'>"+showText+"</a>"); $('#widget').hide(); $('a#toggle_link').click(function() { if ($('a#toggle_link').text()==showText) { $('a#toggle_link').text(hideText); } else { $('a#toggle_link').text(showText); } $('#widget').toggle('slow'); return false; }); }); This is working just with the div which is called widget and the button called idwidget. But on this page i have also : <div class="header"> <h3>How to eat APPLES</h3> <span id="IDsomethingelse" ></span> </div> <div class="content" id="somethingelse"> And i want it to be compatible with the code. I heard about children attribute, do you have an idea how to do that please ? Thank you

  • C++ function for picking from a list where each element has a distinct probability

    - by Stuart
    I have an array of structs and one of the fields in the struct is a float. I want to pick one of the structs where the probability of picking it is relative to the value of the float. ie struct s{ float probability; ... } sArray s[50]; What is the fastest way to decide which s to pick? Is there a function for this? If I knew the sum of all the probability fields (Note it will not be 1), then could I iterate through each s and compare probability/total_probability with a random number, changing the random number for each s? ie if( (float) (rand() / RAND_MAX) < probability)...

  • XPath to find an element with a similar sibling

    - by user364902
    Suppose I have this XML: <x> <e a='1' b='A'/> <e a='1' b='B'/> <e a='1' b='A'/> </x> I'd like to write an xpath to find any elements e which: Have attribute @b = 'A' Have the same value for attribute @a The xpath can't reference the literal value of attribute @a, however. It can reference the literal value of attribute @b. Or more generally, I want to find if there are any instances where there are two or more elements e[@b=A'] with the same value for attribute @a. Is this possible?

  • form element not showing up after adding in through jquery

    - by ooo
    inside a jquery method (on a click event of a button) i have the following code: $(selector).html("<form action='/Tracker/CopyFood' method='post'><input type='hidden' name='Id' value=" + id + "><input class='very-small-input' type='text' name='Quantity' value='1' /> for <select name='Date'><option value='Today'>Today</option><option value='Yesterday'>Yesterday</option></select><select name='Meal'><option value='Breakfast'>Breakfast</option><option value='Lunch'>Lunch</option><option value='Dinner'>Dinner</option><option value='Evening Snack'>Evening Snack</option></select><input type='button' class='submitCopyFood' value='Add'> or <div style='display:inline' class='CancelCopy'>Cancel</div></form> "); it seems to work on the screen, but the button click "submitCopyFood" wasn't firing. When i click "View Selection Source" in firefox, i see the issue. All i see is this: <input name="Id" value="128" type="hidden"><input class="very-small-input" name="Quantity" value="1" type="text"> for <select name="Date"><option value="Today">Today</option><option value="Yesterday">Yesterday</option></select><select name="Meal"><option value="Breakfast">Breakfast</option><option value="Lunch">Lunch</option><option value="Dinner">Dinner</option><option value="Evening Snack">Evening Snack</option></select><input class="submitCopyFood" value="Add" type="button"> or <div style="display: inline;" class="CancelCopy">Cancel</div> Its like i never added the form anywhere. Is there any reason why i dont see the: <form action='/Tracker/CopyFood' method='post'> or the </form> in the source code inside the selected source. Is there something special that i need to do here?

  • Python: Picking an element without replacement

    - by wpeters
    I would like to slice random letters from a string. Given s="howdy" I would like to pick elements from 's' without replacement but keep the index number. For example >>> random.sample(s,len(s)) ['w', 'h', 'o', 'd', 'y'] is close to what I want, but I would actually prefer something like [('w',2), ('h',0), ('o',1), ('d',3), ('y',4)] with letter-index pairs. This is important because the same letter appears in 's' more than once. ie) "letter" where 't' appears twice but I need to distinguish the first 't' from the 'second'. Ideally I actually only need to pick letters as I need them but scrambling and calculating all the letters in a list (as shown above) is ok.

  • "Slice" out one element from a python dictionary

    - by BCS
    I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

  • Actionscript 2.0 element.text always outputs "00"

    - by Mbarry
    Hi everybody, I'm fighting against a strange behaviour with my actionscript! After setting the four integer variables from the MovieTimer sprite (hour, minute, second, mili-sec) and concate them i got always double zero: 00 stop (); delete this.onEnterFrame; var str1; var str2; var mili; var second; var minute; var hour; var timer; mili = _root.MovieTimer.txt_mili.text; second = _root.MovieTimer.txt_sec.text; minute = _root.MovieTimer.txt_min.text; hour = _root.MovieTimer.txt_heures.text; timer = hour+' : '+minute+' : '+second+' : '+mili; _root.MovieSpellFinish.TextTime.text = timer; _root.MovieSpellFinish.TextTime.text outputs: 00 is there any solutions for this??

  • How do I select every 6th element from a list (using Linq)

    - by iDog
    Hi, I've got a list of 'double' values. I need to select every 6th record. It's a list of coordinates, where I need to get the minimum and maximum value of every 6th value. List of coordinates (sample): [2.1, 4.3, 1.0, 7.1, 10.6, 39.23, 0.5, ... ] with hundrets of coordinates. Result should look like: [x_min, y_min, z_min, x_max, y_max, z_max] with exactly 6 coordinates. Following code works, but it takes to long to iterate over all coordinates. I'd like to use Linq instead (maybe faster?) for (int i = 0; i < 6; i++) { List<double> coordinateRange = new List<double>(); for (int j = i; j < allCoordinates.Count(); j = j + 6) coordinateRange.Add(allCoordinates[j]); if (i < 3) boundingBox.Add(coordinateRange.Min()); else boundingBox.Add(coordinateRange.Max()); } Any suggestions? Many thanks! Greets!

  • How can i get the selected option name or id of a select element using jQuery

    - by bill
    Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.
