• Client side javascript, creation of several elements and show each asap

  - by Sirius Lampochkin

  Client side javascript code create some elements (about 50-100) in cycle: for (var i = 0; i < list.Length; i++) { var obj = document.createElement("DIV"); obj.innerHTML = "<span class=\"itemId\">" + list[i].Id + "</span><!-- some more simple code --> "; mainObj.appendChild(obj); } There is some problem with browser rendering, for example IE just freeze until he finished the cycle and then shows all elements in one time. Is there a way to show each created element separately and immediately after "appendChild()"?

• In WebKitGtk+, how can I access parameters in an event listener?

  - by Matthew

  Here is an example in javascript of what I want to do: function handleDragStart(e) { e.dataTransfer.effectAllowed = 'move'; e.dataTransfer.setData('text/plain', 'some data'); } var dragSource = document.querySelector('#dragSource'); dragSource.addEventListener('dragstart', handleDragStart, false, null); But I am having trouble translating this to a GLib-based system. Here is an example in Vala: void on_dragstart(EventTarget event_target) { // How can I access the equivalent of e.dataTransfer? } WebKit.WebView web_view = ... WebKit.DOM.Document document = web_view.get_dom_document(); WebKit.DOM.Element drag_source = document.query_selector('#dragSource'); drag_source.add_event_listener("dragstart", (Callback) on_dragstart, false, null); While I am using Vala, an answer in any language interacting with WebKitGtk+ directly would be helpful.

• CouchDB Map/Reduce raises execption in reduce function?

  - by fuzzy lollipop

  my view generates keys in this format ["job_id:1234567890", 1271430291000] where the first key element is a unique key and the second is a timestamp in milliseconds. I run my view with this elapsed_time?startkey=["123"]&endkey=["123",{}]&group=true&group_level=1 and here is my reduce function, the intention is to reduce the output to get the earliest and latest timestamps and return the difference between them and now function(keys,values,rereduce) { var now = new Date().valueOf(); var first = Number.MIN_VALUE; var last = Number.MAX_VALUE; if (rereduce) { first = Math.max(first,values[0].first); last = Math.min(last,values[0].last); } else { first = keys[0][0][1]; last = keys[keys.length-1][0][1]; } return {first:now - first, last:now - last}; } and when processing a query it constantly raises the following execption: function raised exception (new TypeError("keys has no properties", "", 1)) I am making sure not to reference keys inside my rereduce block. Why does this function constantly raise this exception?

• Subversion LDAP Configuration

  - by dbyrne

  I am configuring a subversion repository to use basic LDAP authentication. I have an entry in my http.conf file that looks like this: <Location /company/some/location> DAV svn SVNPath /repository/some/location AuthType Basic AuthName LDAP AuthBasicProvider ldap Require valid-user AuthLDAPBindDN "cn=SubversionAdmin,ou=admins,o=company.com" AuthLDAPBindPassword "XXXXXXX" AuthLDAPURL "ldap://company.com/ou=people,o=company.com?personid" </Location> This works fine for living, breathing people who need to log in. However, I also need to provide application accounts access to the repository. These accounts are in a different OU. Do I need to add a whole new <location> element, or can I add a second AuthLDAPURLto the existing entry?

• WPF Validation of clipboard Data

  - by Peter

  Hello normal validation is always related to some control, but in my case there is no control to fire validation when its content changes and to show errortemplate to the user. because the data to be validated is in the cipboard. when the user presses "PASTE" button viewmodel processes the data and finds it to be invalid. but what is the best way to invoke WPF validation in this case? as far as i understand using IDataErrorInfo is the way to go, but what is the best way to start validation. and whst is the best way of displaying the error? errortemplate of the button element? Thanks a lot for help. Peter

• Function Object in Java .

  - by Tony

  I wanna implement a javascript like method in java , is this possible ? Say , I have a Person class : public class Person { private String name ; private int age ; // constructor ,accessors are omitted } And a list with Person objects: Person p1 = new Person("Jenny",20); Person p2 = new Person("Kate",22); List<Person> pList = Arrays.asList(new Person[] {p1,p2}); I wanna implement a method like this: modList(pList,new Operation (Person p) { incrementAge(Person p) { p.setAge(p.getAge() + 1)}; }); modList receives two params , one is a list , the other is the "Function object", it loops the list ,and apply this function to every element in the list. In functional programming language,this is easy , I don't know how java do this? Maybe could be done through dynamic proxy, does that have a performance trade off?

• Add class to .hover functionality on a specific class name - jQuery

  - by marcamillion

  So, throughout my entire document, I would like for every single time the user hovers over an element with a specific class name, I would like a class to be added. My CSS looks like this: .hotspot:hover, .hotspothover { border: 4px solid #fff; box-shadow: 0px 0px 20px #000; -webkit-box-shadow: 0px 0px 20px #000; -moz-box-shadow: 0px 0px 20px #000; z-index: 1; } Class name: "hotspot". I tried this, but it doesn't seem to work: $("#hotspot.hover #hotspothover").addClass("bubble bottom"); Thanks.

• (N)Hibernate: deleting orphaned ternary association rows when either associated row is deleted.

  - by anthony

  I have a ternary association table created using the following mapping: <map name="Associations" table="FooToBar"> <key column="Foo_id"/> <index-many-to-many class="Bar" column="Bar_id"/> <element column="AssociationValue" /> </map> I have 3 tables, Foo, Bar, and FooToBar. When I delete a row from the Foo table, the associated row (or rows) in FooToBar is automatically deleted. This is good. When I delete a row from the Bar table, the associated row (or rows) in FooToBar remain, with a stale reference to a Bar id that no longer exists. This is bad. How can I modify my hbm.xml to remove stale FooToBar rows when deleting from the Bar table?

• C++ - dynamic pointer of array

  - by Eagle

  Hi to all, first i would like to say i am Newbie in C++. As part of my master thesis i am writing a program in C++ which also get as parameters the variables m and d (both integers). Were d is the power of 2 (this means 2^d elements). Parameter m define the number of possible interactions between one element and the total group (2^d elements). The number of possible interactions is computed as following: \kappa = \sum_{i=0}^m\binom{d}{i} (at present i generate vector of vectors for 2^d x \kappa, but my Prof. would like me to create different statistics to different m's. My first though was to to generate a dynamic array of m arrays of different sizes... Then i though of defining a 3-dim array with the biggest needed 2d array, but also program speed is important (e.g d = 20). i would like to ask for your advice how to define such kind of dynamic array that will also be fast. Regards

• jQuery validator and a custom rule that uses AJAX

  - by thatweblook

  Hi, I read your reply regarding the jQuery validator where you outline a method to check a username against a value in a database. Ive tried implementing this method but no matter what is returned from the PHP file I always get the message that the username is already taken. Here is ths custom method... $.validator.addMethod("uniqueUserName", function(value, element) { $.ajax({ type: "POST", url: "php/get_save_status.php", data: "checkUsername="+value, dataType:"html", success: function(msg) { // if the user exists, it returns a string "true" if(msg == "true") return false; // already exists return true; // username is free to use } })}, "Username is Already Taken"); And here is the validate code... username: { required: true, uniqueUserName: true }, Is there a specific way i am supposed to return the message from php. Thanks A

• 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.

• How to add SQL elements to an array in PHP

  - by DanLeaningphp

  So this question is probably pretty basic. I am wanting to create an array from selected elements from a SQL table. I am currently using: $rcount = mysql_num_rows($result); for ($j = 0; $j <= $rcount; $j++) { $row = mysql_fetch_row($result); $patients = array($row[0] => $row[2]); } I would like this to return an array like this: $patients = (bob=>1, sam=>2, john=>3, etc...) Unfortunately, in its current form, this code is either copying nothing to the array or only copying the last element.

• Capturing the contents of <select>

  - by joey mueller

  I'm trying to use a regular expression to capture the contents of all option values inside an HTML select element For example, in: <select name="test"> <option value="blah">one</option> <option value="mehh">two</option> <option value="rawr">three</option> </select> I'd like to capture one two and three into an array. My current code is var pages = responseDetails.responseText.match(/<select name="page" .+?>(?:\s*<option .+?>([^<]+)<\/option>)+\s*<\/select>/); for (var c = 0; c<pages.length; c++) { alert(pages[c]); } But it only captures the last value, in this case, "three". How can I modify this to capture all of them? Thanks!

• Make jQuery-ui draggable handle cover entire page

  - by Acorn

  What would be the best way to make an element draggable when clicking anywhere in the window? Would I have to use a container <div> that covers the whole window? I tried making the body draggable but that didn't work. The problem with using a container <div> is that it moves and therefore doesn't cover the whole of the screen any more after it has been dragged. What about making a really vast container <div> that spans a large number of pixels in every direction so you would never get to the edge of it. Is that a bad idea? The idea (simplified) is to have a page with a square in the middle that can be dragged by dragging any part of the window. Here's a wonderfully unnecessary mockup :)

• How to select a dynamic datepicker instance in order to extend it with jQuery

  - by JaredC

  I'm trying to control positioning of a jQuery datepicker element. I like the solution offered at http://stackoverflow.com/questions/1818670/how-to-control-positioning-of-jqueryui-datepicker for overriding the _checkOffset fn: $.extend(window.DP_jQuery.datepicker,{_checkOffset:function(inst,offset,isFixed){return offset}}); However, this results in a 'window.DP_jQuery is undefined' error. Upon inspection, I can see that the DP_jQuery object in the DOM gets named with a random string, like so: DP_jQuery_123456. If I use this full name in the above code, it works wonderfully. My question is whether there's a way to exend the _checkOffset fn for a datepicker instance without knowing before-hand what the instance name is? For example, can I use some sort of wildcard to select all datepicker instances that begin with 'DP_jQuery_'? Thanks

• What is the JavaScript variable scope in a switch / case statment?

  - by Todd Moses

  While creating JavaScript with ASP.NET MVC I noticed several scope warnings and realized that I am missing something with understanding the variable scope inside the switch / case statement. Warning: 'i' is already defined referring to case b and case c My code looks similar to this: switch(element) { case 'a': for(var i=0; i < count; i++){ do something } break; case 'b': for(var i=0; i < count; i++){ do something } break; case 'c': for(var i=0; i < count; i++){ do something } break; } I thought scope ended with each break statement but it seems that scope does not end until the end of the switch/case. Is scope for the entire switch/case?

• crazy things with PHP array...

  - by user296516

  Hi, A very strange thing, I have an array where element 7 is '[1000137d]', but when I try to compare it by using if ( $array[7] == '[1000137d]' ) it will return a negative. echo $array[7]; echo '<br>'; echo '[1000137d]'; echo '<br>'; echo md5($array[7]); echo '<br>'; echo md5('[1000137d]'); this code would echo out: [1000137d] [1000137d] ca9983334e720042e3a6cbb1dd6b7fd2 3b1c21e661bd7d38deda1f4a45eaa23b as you can see $array[7] is identical to [1000137d], yet their md5's differ. what do you think might be the problem? Thanks!

• JQuery-tmpl Template Switching Not working.

  - by Mike

  I'm trying to implement "more/less" functionality using the official jquery-tmpl plugin. I've looked at the examples, but I cannot seem to get the functionality to work in my own implementation. When I click on one of my "More" buttons, I seem to get an error thrown of: Uncaught TypeError: Property 'tmpl' of object #<an Object> is not a function This is my implementation here From what I can tell, the example I'm trying to replace is doing the following: Render the "Master" template On-click: Find the corresponding template object (tmplItem) to the clicked element. Pass in reference to a new template. Call the update function to re-render. Have I understood the documentation wrong? From what I can tell I'm doing the same thing as the example on the official documentation.

• object representation and value representation

  - by FredOverflow

  3.9 §4 says: The object representation of an object of type T is the sequence of N unsigned char objects taken up by the object of type T, where N equals sizeof(T). The value representation of an object is the set of bits that hold the value of type T. For trivially copyable types, the value representation is a set of bits in the object representation that determines a value, which is one discrete element of an implementation-defined set of values. Does "The value representation of an object" imply that values are always stored in objects? What is the value representation of non-trivially copyable types?

  Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

The problem is, how does the data get delivered to the instance of DataRetriever that requested it? I'm really stuck here.
