• step attribute not working with HTML5 <input type="range"> on Safari

  - by Claudiu

  Are there known issues with range inputs not working fully on Safari? I have the following input element: <input type=?"range" min=?"0" max=?"360" step=?"0.0001" value=?"0">? On Chrome, the input goes according to the step variable. On Safari, it only goes by integer values. Even setting the step to 10 still makes it go by increments of 1. I'm confused because I thought Chrome and Safari both used WebKit.

• Javascript: Display message when user leaves site

  - by Brian Rasmusson

  Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

• Can jQuery perform a compound select against the top level only?

  - by harpo

  Basically, is there a way to write a.children('.outer').children('.inner') without the intermediate selector? I can't write $('.outer > .inner', a) because I don't want to do full-depth search against a — I know that the .outer elements are immediate children of a. It's partly a matter of "elegance", but partly because I'm trying to avoid "throwaway" element sets. Yes, jQuery may in effect do the same thing, but it has a better chance of optimizing (at least in theory), when it knows the full query's intent.

• IE 8 and text fading

  - by DMIL

  I have a problem with fading text in IE 8, 7 and 6 (obviously). The text has a black outline during the animation that completely ruins the effect. Is there a workaround? I've read a bunch of answers about this problem and none made sense. Please take a look at this simple jsFiddle http://jsfiddle.net/LhSK7/ in IE 8, and show me how to fix it if possible. Edit: screenshot of the problem: http://i43.tinypic.com/1z6h1th.png I thought it might be because of the VirtualBox, but all other browsers display it correctly in VirtualBox. Edit #2: the problem can sort of be solved by setting the background color of the element being faded, which while still pretty ugly in IE 8 and below, at least gets rid of the black outline.

• How to use LINQ To Entities for filtering when many methods are not supported?

  - by Kinderchocolate

  Hi, I have a table in SQL database: ID Data Value 1 1 0.1 1 2 0.4 2 10 0.3 2 11 0.2 3 10 0.5 3 11 0.6 For each unique value in Data, I want to filter out the row with the largest ID. For example: In the table above, I want to filter out the third and fourth row because the fifth and sixth rows have the same Data values but their IDs (3) are larger (2 in the third and fourth row). I tried this in Linq to Entities: IQueryable<DerivedRate> test = ObjectContext.DerivedRates.OrderBy(d => d.Data).ThenBy(d => d.ID).SkipWhile((d, index) => (index == size - 1) || (d.ID != ObjectContext.DerivedRates.ElementAt(index + 1).ID)); Basically, I am sorting the list and removing the duplicates by checking if the next element has an identical ID. However, this doesn't work because SkipWhile(index) and ElementAt(index) aren't supported in Linq to Entities. I don't want to pull the entire gigantic table into an array before sorting it. Is there a way?

• databinding to self without code

  - by jcollum

  I'm building a UserControl in WPF. The control has two properties, Title and Description, that I'd like to bind to two textblocks. Seems real straightforward, and I got it working, but I'm curious about something. To get it to work I had to add this code: void CommandBlock_Loaded(object sender, RoutedEventArgs e) { this.DataContext = this; } My bindings look like this: <TextBlock Text="{Binding Title}" Width="100" ... /> <TextBlock Text="{Binding Description}" Width="100" ... /> What I'm wondering is how come I couldn't get it to work without the this.DataContext = this; and instead use DataContext="{Binding RelativeSource={RelativeSource Self}}" (in the UserControl element of the markup)? I'm sure I'm missing something about DataContexts but don't know what.

• How to compare two lists with duplicated items in one list?

  - by eladc

  I need to compare list_a against many others. my problem starts when there's a duplicated item in the other lists (two k's in other_b). my goal is to filter out all the lists with the same items (up to three matching items). list_a = ['j','k','a','7'] other_b = ['k', 'j', 'k', 'q'] other_c = ['k','k','9','k'] >>>filter(lambda x: not x in list_a,other_b) ['q'] I need a way that would return ['k', 'q'], because 'k' appears only once in list_a. comparing list_a and other_c with set() isn't good for my purpose since it will return only one element: k. while I need ['k','9','k'] I hope I was clear enough. Thank you

• jQuery - How to Prevent Animation Queue Buildup with Double Animations?

  - by Jason

  Hello, I was taking a look at this tutorial here to prevent animation buildups: http://www.learningjquery.com/2009/01/quick-tip-prevent-animation-queue-buildup My situation: I am doing a double animation like this below, and would like the prevent the animation build up.

• How to return relationships in a custom un-typed dataservice provider

  - by monkey_p

  I have a custom .Net DataService and can't figure out how to return the data for relationships. The data base has 2 tables (Customer, Address). A Customer can have multiple addresses, but each address can only have on customer. I'm using Dictionary<string,object> as my data type. My question, for the following 2 urls how do i return the data. http://localhost/DataService/Customer(1)/Address http://localhost/DataService/Address(1)/Customer For the none relational queries I return a List<Dictionary<string,object>> So I imagined for the relation I should just populate the element with a either a Dictionary<string,object> for the single ones and a List<Dictionary<string,object>> for many relationships. But this just gives me a NullRefferenceException So what am I doing wrong?

• C# Array Maximum

  - by Betamoo

  I have 2 arrays named Arr1 and Arr2 in C#. They are of the exact same dimensions... I need to get the element of Arr1 corresponding to maximum of elements in Arr2 beginning with given indices ... e.g Get indices of the max of Arr2 [ 1 , 10 , 3 , i , j ] for all i,j Return Arr1 [ 1 , 10 , 3 , i , j ] Of course I need the elegant solution (not the "loop for them" one...) Please Note: I do not want to loop through the arrays, because it is 11 dimensional!!.. the code will be ugly and error prone.. and I may run out of variable names :)

• Jmeter Query new user

  - by Sri

  First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

• errorPage directive works, but error-page in web.xml doesn't?

  - by danb

  I get jsp exceptions causing a forward to my error page when I put this at the top of my JSPs... <%@ page errorPage="/error.page" %> but when I try to do it globally with web.xml like so: <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/error.page</location> </error-page> I just get a blank page... I've also tried putting /error.jsp in the location element.. but no love with that either.. I am triggering an exception with a jsp that just contains this: <%if(true)throw new RuntimeException("test exception");%> I do see the exception in the console from tomcat but I just can't get that error page to show without a directive on every jsp... am I missing something simple here?

• Is there a need for zero-out DIV's margin and padding?

  - by ssg

  I wonder if on any browser div element comes with a preset margin/padding value other than zero. As far as I know, div and span come with zero padding and margin values by standard to make them suitable canvas for style decoration. Even better, is there a definite standard for default styles for all elements that is cross-browser which we can make assumptions upon? For instance FORM comes with top/bottom margins, OL/UL come with padding-left's. I occasionally see a * { margin: 0; padding: 0; } and this just looks like a dirty hack without knowing the reasons or consequences. Anyone has any better approach to this?

  I have a dialog in which there are 2 textboxes. I want to reset the textboxes values once the dialog is destroyed. How can I do that? If I have entered values in the textboxes and clicked cancel, reopening the dialog will show the data entered previously. function setDialogWindows($element) { $('#change').dialog({ autoOpen: true, width: 380, buttons: { "Cancel": function() { $(this).dialog('destroy'); }, "Accept": function() { } }): } $(#link').click(function() { setDialogWindows('#change'); }); <div id="change" title="Change password" > <input type="hidden" id="User_Name" name="Name"/> <input type="textbox" id="text1" /> <input type="textbox" id="text2" /> </div>

• Programmatically scroll to an Anchor Tag

  - by Anders

  Consider the following code: <a href="#label2">GoTo Label2</a> ... [content here] ... <a name="label0"></a>More content <a name="label1"></a>More content <a name="label2"></a>More content <a name="label3"></a>More content <a name="label4"></a>More content Is there a way to emulate clicking on the "GoTo Label2" link to scroll to the appropriate region on the page through code? EDIT: An acceptable alternative would be to scroll to an element with a unique-id, which already exists on my page. I would be adding the anchor tags if this is a viable solution.

• execute javascsript for loop alternately forward and backward

  - by Stiff Mittens

  What I'm trying to do is iterate through an array in chunks, alternating the direction of iteration from chunk to chunk. Confused? So am I. For example, if I want to loop thru an array with 25 elements, but I want to do it in this order: 0, 1, 2, 3, 4, 9, 8, 7, 6, 5, 10, 11, 12, 13, 14, 19, 18, 17, 16, 15, 20, 21, 22, 23, 24, what would be the most efficient way of doing this? I'm looking for something scalable because the array I'm working with now is actually 225 elements and I want to traverse it in 15 element chunks, but that may change at some point. So far, the only method I've figured out that actually works is to hard-wire the iteration order into a second array and then iterate through that in the normal way to get the indices for the original array. But that sucks. Any help would be greatly appreciated.

• load data from external file jQuery

  - by bah

  Hi, I need to take data from external file and format it, the problem is, i want to have that data stored into a variable. Load method works for me, because i need to load not the whole document, but just a part of it, but then again, i want to load to variable and not to some dom element. $.get can do this, but it doesn't support selectors. Is there any way I could make this? Now examples: Mine external file consists of a table, which has format like this: <table><tr><td><img /></td></tr><tr><td><a></a></td><td><span></span></td></tr></table> I need to extract img, a and span tags because I need them to be displayed in different order than they're now. So, is there any chance for me that i could make this work? Thanks.

• jquery for each function

  - by jonathan p

  I have added a show more or less function to a div - this all works fine however now i need to only allow this functionality if a element is over a certain height in this case. there are numerous classes of the same so i need to do the check on each element. although i am having problems getting it to work see code below : $(document).ready(function() { $(".less").hide(); $(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight < 150) { $(".more").hide(); } }); $(".more").click(function() { var paragraphHeight = ($(this).parent().parent().find('.appsList').height()); if (paragraphHeight > 150) { $(this).parent().parent().find('.appsHolderBody').animate({height:(paragraphHeight + 100) }); $(this).hide('slow'); $(this).parent().find('.less').show(); } return false; }); $(".less").click(function() { $(this).parent().parent().find('.appsHolderBody').animate({height:190 }); $(this).hide('slow'); $(this).parent().find('.more').show(); return false; }); }); Any help would be greatly appreciated - please note when i am targeting the parent using .parent.parent i know its not pretty but could'nt get it to run using eq(4) for some reason. so the main problem is with this part of code $(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight < 150) { $(".more").hide(); } it hides all of the elements $(".more") instead of the ones that match the condition. html as requested <div class="appsHolder"> <div class="appsHolderBody"> <h5 class="appTitle">General Apps</h5> <ul class="appsList"> <li class="mainAppList">Resource Manager</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Resource Manager</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> </ul> </div> <div class="appsHolderExpander"> <a href="" class="more">More <img src="/wps/PA_applicationsintros/./img/downArrow.png" /></a> <a href="" class="less">Less <img src="/wps/PA_applicationsintros/./img/upArrow.png" /></a> </div> </div> <div class="appsHolderAdvertising"> <div class="appsHolderBody"> <h5 class="appTitle">Advertising Apps</h5> <ul class="appsList"> <li class="mainAppList">ATEX</li> <li><a href="">Launch</a> <a href="">Info</a></li> </ul> </div> <div class="appsHolderExpander"> <a href="" class="more">More <img src="/wps/PA_applicationsintros/./img/downArrow.png" /></a> <a href="" class="less">Less <img src="/wps/PA_applicationsintros/./img/upArrow.png" /></a> </div> </div> cheers in advance

• Retrieving data from simplexml_load_file

  - by Kole Odd

  Working with the simplexml_load_file() function, I get a side effect. To understand what I mean, see this code: $result = simplexml_load_file($xml_link); $arr = array(); foreach ($result->element as $elem) { $arr[] = $elem->number[0]; } print_r($arr); Output: Array ( [0] => SimpleXMLElement Object ( [0] => 330411879136 ) [1] => SimpleXMLElement Object ( [0] => 370346266228 ) [2] => SimpleXMLElement Object ( [0] => 370346266223 ) ) How would I store data into the array so that output would look like so: Array ( [0] => 330411879136 [1] => 370346266228 [2] => 370346266223 )
