  • Android XmlSerializer limitation?

    - by Rexb
    Hi all, My task is just to get an xml string using XmlSerializer. Problem is that it seems like the serializer stops adding any new element and/or attribute to the xml document when it reaches certain length (perhaps 10,000 char?). My questions: have you experience this kind of problem? What could be possible solutions? Here is my sample test code: public void doSerialize() throws XmlPullParserException, IllegalArgumentException, IllegalStateException, IOException { StringWriter writer = new StringWriter(); XmlSerializer serializer = XmlPullParserFactory.newInstance().newSerializer(); serializer.setOutput(writer); serializer.startDocument(null, null); serializer.startTag(null, "START"); for (int i = 0; i < 20; i++) { serializer.attribute(null, "ATTR" + i, "VAL " + i); } serializer.startTag(null, "DATA"); for (int i = 0; i < 500; i++) { serializer.attribute(null, "attr" + i, "value " + i); } serializer.endTag(null, "DATA"); serializer.endTag(null, "START"); serializer.endDocument(); String xml = writer.toString(); // value: until 493rd attribute int n = xml.length(); // value: 10125 } Any help will be greatly appreciated.

  • Implementing list position locator in C++?

    - by jfrazier
    I am writing a basic Graph API in C++ (I know libraries already exist, but I am doing it for the practice/experience). The structure is basically that of an adjacency list representation. So there are Vertex objects and Edge objects, and the Graph class contains: list<Vertex *> vertexList list<Edge *> edgeList Each Edge object has two Vertex* members representing its endpoints, and each Vertex object has a list of Edge* members representing the edges incident to the Vertex. All this is quite standard, but here is my problem. I want to be able to implement deletion of Edges and Vertices in constant time, so for example each Vertex object should have a Locator member that points to the position of its Vertex* in the vertexList. The way I first implemented this was by saving a list::iterator, as follows: vertexList.push_back(v); v->locator = --vertexList.end(); Then if I need to delete this vertex later, then rather than searching the whole vertexList for its pointer, I can call: vertexList.erase(v->locator); This works fine at first, but it seems that if enough changes (deletions) are made to the list, the iterators will become out-of-date and I get all sorts of iterator errors at runtime. This seems strange for a linked list, because it doesn't seem like you should ever need to re-allocate the remaining members of the list after deletions, but maybe the STL does this to optimize by keeping memory somewhat contiguous? In any case, I would appreciate it if anyone has any insight as to why this happens. Is there a standard way in C++ to implement a locator that will keep track of an element's position in a list without becoming obsolete? Much thanks, Jeff

  • Vertically align a heading and a paragraph in a div

    - by davey
    I'm trying to vertically align a h1 element and p in the middle of a div floated left but they end up next to each other vertically aligned. Im pretty sure it to do with the table-cell display but don't know how to vertically align without it. my code gives me: . . Heading Paragraph . . I want: . . Heading Paragraph . . heres my code: CSS: #HDRtext { float: left; width: 30%; height: 335px; padding: 0; display: table; color: white; } #HDRtext h1 { font-family: Georgia; font-size: 2em; display: table-cell; vertical-align: middle; } #HDRtext p { display: table-cell; vertical-align: middle; font-size:1em; font-family: Georgia; }

  • How can I bind Wpf DataGridColumn to an object?

    - by John
    I want to bind the columns of my WPF DataGrid to some objects in a Dictionary like this: Binding Path=Objects[i] where Objects is my Dictionary of objects, so that each cell will represent an Object element. How can I do that? I suppose that I need to create a template for my cell, which I did, but how to get the result of column binding in my template? I know that by default the content of a DataGridCell is a TextBlock and it's Text property is set through column binding result, but if that result is an object I guess that I have to create a ContentTemplate. How do I do that, as the stuff I tried is not displaying anything. Here it is what I tried: <Style x:Key="CellStyle" TargetType="{x:Type dg:DataGridCell}"> <Setter Property="Template"> ---it should realy be ContentTemplate? <Setter.Value> <ControlTemplate> <controls:DataGridCellControl CurrentObject="{Binding }"/> -- I would expect to get the object like this for this column path : Path=Objects[i] but is not working </ControlTemplate> </Setter.Value> </Setter> </Style> So, to make myself completly clear, i want to get in CurrentObject property of my DataGridCellControl the current object that should result if I set the column binding in my data grid like this Path=Objects[i]. Thank you for any suggestion, John.

  • emacs lisp mapcar doesn't apply function to all elements?

    - by Stephen
    Hi, I have a function that takes a list and replaces some elements. I have constructed it as a closure so that the free variable cannot be modified outside of the function. (defun transform (elems) (lexical-let ( (elems elems) ) (lambda (seq) (let (e) (while (setq e (car elems)) (setf (nth e seq) e) (setq elems (cdr elems))) seq)))) I call this on a list of lists. (defun tester (seq-list) (let ( (elems '(1 3 5)) ) (mapcar (transform elems) seq-list))) => ((10 1 8 3 6 5 4 3 2 1) ("a" "b" "c" "d" "e" "f")) It does not seem to apply the function to the second element of the list provided to tester(). However, if I explicitly apply this function to the individual elements, it works... (defun tester (seq-list) (let ( (elems '(1 3 5)) ) (list (funcall (transform elems) (car seq-list)) (funcall (transform elems) (cadr seq-list))))) => ((10 1 8 3 6 5 4 3 2 1) ("a" 1 "c" 3 "e" 5)) If I write a simple function using the same concepts as above, mapcar seems to work... What could I be doing wrong? (defun transform (x) (lexical-let ( (x x) ) (lambda (y) (+ x y)))) (defun tester (seq) (let ( (x 1) ) (mapcar (transform x) seq))) (tester (list 1 3)) => (2 4) Thanks

  • Help with PHP simplehtmldom - Modifiying a form.

    - by onemyndseye
    Ive gotten some great help here and I am so close to solving my problem that I can taste it. But I seem to be stuck. I need to scrape a simple form from a local webserver and only return the lines that match a users local email (i.e. onemyndseye@localhost). simplehtmldom makes easy work of extracting the correct form element: foreach($html->find('form[action*="delete"]') as $form) echo $form; Returns: <form action="/delete" method="post"> <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php"> http://www.linux.com/rss/feeds.php </a> [email: onemyndseye@localhost (Default) ]<br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml"> http://www.ubuntu.com/rss.xml </a> [email: onemyndseye@localhost (Default) ]<br /> However I am having trouble making the next step. Which is returning lines that contain 'onemyndseye@localhost' and removing it so that only the following is returned: <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php">http://www.linux.com/rss/feeds.php</a> <br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml">http://www.ubuntu.com/rss.xml</a> <br /> Thanks to the wonderful users of this site Ive gotten this far and can even return just the links but I am having trouble getting the rest... Its important that the complete <input> tags are returned EXACTLY as shown above as the id and name values will need to be passed back to the original form in post data later on. Thanks in advance!

  • I have a WPF/Silverlight ListView whose height is unpredictable and too high. How do I control it be

    - by Rob Perkins
    I have a ListView element with a DataTemplate for each ListViewItem defined as follows. When run, the ListView's height is not collapsed onto the items in the view, which is undesirable behavior: <DataTemplate x:Key="LicenseItemTemplate"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding company}"></TextBlock> <Grid Grid.Row="1" Style="{StaticResource HiddenWhenNotSelectedStyle}"> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <Button Grid.Row="0">ClickIt</Button> </Grid> </Grid> </DataTemplate> The second row of the outer grid has a style applied which looks like this. The purpose of the style is to : <Style TargetType="{x:Type Grid}" x:Key="HiddenWhenNotSelectedStyle" > <Style.Triggers> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="False"> <Setter Property="Grid.Visibility" Value="Collapsed" /> </DataTrigger> <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={ RelativeSource Mode=FindAncestor, AncestorType={x:Type ListViewItem} } }" Value="True"> <Setter Property="Grid.Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> The ListView renders like this: The desired appearance is this, when none of the elements are selected: ...with, of course, the ListView's height adjusting to accommodate the additional content when the second grid is made visible by selection. What can I do to get the desired behavior?

  • Is there a default way to get hold of an internal property in jQueryUi widget?

    - by prodigitalson
    Im using an existing widget from the jquery-ui labs call selectmenu. It has callback options for the events close and open. The problem is i need in these event to animate a node that is part of the widget but not what its connected to. In order to do this i need access to this node. for example if i were to actually modify the widget code itself: // ... other methods/properties "open" : function(event){ // ... the original logic // this is my animation $(this.list).slideUp('slow'); // this is the orginal call to _trigger this._trigger('open', event, $this._uiHash()); }, // ... other methods/properties However when in the scope of the event handler i attach this is the orginal element i called the widget on. I need the widget instance or specifically the widget instance's list property. $('select#custom').selectmenu({ 'open': function(){ // in this scope `this` is an HTMLSelectElement not the ui widget } }); Whats the best way to go about getting the list property from the widget?

  • Javascript/jQuery: programmatically follow a link

    - by Dan
    In Javascript code, I would like to programmatically cause the browser to follow a link that's on my page. Simple case: <a id="foo" href="mailto:[email protected]">something</a> function goToBar() { $('#foo').trigger('follow'); } This is hypothetical as it doesn't actually work. And no, triggering click doesn't do it. I am aware of window.location and window.open but these differ from native link-following in some ways that matter to me: a) in the presence of a <base /> element, and b) in the case of mailto URLs. The latter in particular is significant. In Firefox at least, calling window.location.href = "mailto:[email protected]" causes the window's unload handlers to fire, whereas simply clicking a mailto link does not, as far as I can tell. I'm looking for a way to trigger the browser's default handling of links, from Javascript code. Does such a mechanism exist? Toolkit-specific answers also welcome (especially for Gecko).

  • Flex dynamic form height

    - by Daryl
    I'm not sure if this is possible, is there a way to get the <mx:Form> to set its own height based on the position of an element within it? For example something like this: <mx:Form height="{submitBtn.y + submitBtn.height}"> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem>... </mx:FormItem> <mx:FormItem> <s:Button id="submitBtn" label="Submit" /> </mx:FormItem> </mx:Form> where the form height is dynamically set based on submitBtn's y position and its height. I tried using Alert.show to show these values and turned out submitBtn.y = 0 and submitBtn.height = 21. height sounds reasonable, but I know the submitBtn.y can't be 0 since it's below several other Is it possible to set the form height dynamically?

  • How to accurately resize nested elements with ems and font-size percentage?

    - by moonDogDog
    I have a carousel with textboxes for each image, and my client (who knows nothing about HTML) edits the textboxes using a WYSIWYG text editor. The resulting output is akin to your worst nightmares; something like: <div class="carousel-text-container"> <span style="font-size:18pt;"> <span style="font-weight:bold;"> Lorem <span style="font-size:15pt:">Dolor</span> </span> Ipsum <span style="font-size:19pt;"><span>&nbsp;<span>Sit</span>Amet</span> </span> </div> This site has to be displayed at 3 different sizes to accomodate smaller monitors, so I have been using CSS media queries to resize the site. Now I am having trouble resizing the text inside the textbox correctly. I have tried using jQuery.css to get the font size of each element in px, and then convert it to em. Then, by setting a font-size:x% sort of declaration on .carousel-text-container, I hoped that that would resize everything properly. Unfortunately, there seems to be a recursive nature with how font-size is applied in ems. That is, .example is not resized properly in the following because its parent is also influencing it <span style="font-size:2em;"> Something <span class="example" style="font-size:1.5em;">Else</span> </span> How can I resize everything reliably and precisely such I can achieve a true percentage of my original font size, margin, padding, line-height, etc. for all the children of .carousel-text-container?

  • PHP form processing - how to capture text from field that has variable Name/ID

    - by user80151
    I have a form that has a field pulled from the database as a dropdown. I need to get the text selected in the dropdown but I don't know in advance what the field ID will be. This is basically just a form that has already been generated. I don't need to pull anything from the database, it's already on this page. All I need to do is get the form information and email it, no writing to the database. I know how to do the _Request for the other fields based on the ID but I'm not sure how to do this one. The ID changes. It can be ID=1, ID-2, etc. I need to do something like: _REQUEST form element where ID is LIKE "ID[*]" or something similar. Any suggestions or links to tutorials? Here are a couple samples of what the dropdown renders on the page: <div class="wrapperAttribsOptions"> <h4 class="optionName back"><label class="attribsSelect" for="attrib- 1">Model</label></h4> <div class="back"> <select name="id[1]" id="attrib-1"> <option value="45">VC3-4C</option> <option value="1">VC3-4PG</option> <option value="3">VC3-4SG</option> <div class="wrapperAttribsOptions"> <h4 class="optionName back"><label class="attribsSelect" for="attrib-14">SPK Model</label></h4> <div class="back"> <select name="id[14]" id="attrib-14"> <option value="43">SPK-4</option> <option value="44">SPK-8</option> </select> TIA

  • Why does Hibernate 2nd level cache only cache queries within a session?

    - by Synesso
    Using a named query in our application and with ehcache as the provider, it seems that the query results are tied to the session within the cache. Any attempt to access the value from the cache for a second time results in a LazyInitializationException We have set lazy = true for the following mapping because this object is also used by another part of the system which does not require the reference... and we want to keep it lean. <class name="domain.ReferenceAdPoint" table="ad_point" mutable="false" lazy="false"> <cache usage="read-only"/> <id name="code" type="long" column="ad_point_id"> <generator class="assigned" /> </id> <property name="name" column="ad_point_description" type="string"/> <set name="synonyms" table="ad_point_synonym" cascade="all-delete-orphan" lazy="true"> <cache usage="read-only"/> <key column="ad_point_id" /> <element type="string" column="synonym_description" /> </set> </class> <query name="find.adpoints.by.heading">from ReferenceAdPoint adpoint left outer join fetch adpoint.synonyms where adpoint.adPointField.headingCode = ?</query> Here's a snippet from our hibernate.cfg.xml <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property> <property name="hibernate.cache.use_query_cache">true</property> It doesn't seem to make sense that the cache would be constrained to the session. Why are the cached queries not usable outside of the (relatively short-lived) sessions?

  • Nokogiri changing custom elements

    - by dagda1
    Hi, I have sample html that I have marked up with some special tags that will be used by a different program, an example of the html is below. You should note the <START:organization>..<END> elements. <html> <head/> <body> <ul> <li> <START:organization> Advanced Integrated Pest Management <END> </li> <li> <START:organization> American Bakers Association <END> </li> </ul> </body> </html> I wanted to use nokogiri to preprocess the html to easily remove irrelevant tags like <script>. I created the following extension to the nokogiri document class: module Nokogiri module HTML class Document def prepare_html xpath("//script").remove to_html.remove_new_lines end end end end The problem is that nokogiri is changing the <START:organization> element to <organization>. Is there anyway that I can preserve the htnl to maintain my custom markup tags? Thanks Paul

    How do I apply a parameter to a select and order attribute in a xsl:sort element? I'ld like to do this dynamic with PHP with something like this: $xsl = new XSLTProcessor(); $xslDoc = new DOMDocument(); $xslDoc->load( $this->_xslFilePath ); $xsl->importStyleSheet( $xslDoc ); $xsl->setParameter( '', 'sortBy', 'viewCount' ); $xsl->setParameter( '', 'order', 'descending' ); But I'ld first have to now how to get this to work.

  • Modifying CSS class property values on the fly with JavaScript / jQuery

    - by JPN
    all. I've run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style. I know how to use jQuery to assign width, height, etc. to an element, but what I'm trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements. What I'm building is a slideshow of images that occupy the full viewport, recalculating the image's width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image). I have successfully been able to get it to work on one image, and now I'm trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image. Can the values of properties in a class be modified on the fly? I'm sure the answer is out there, I'm probably just not using the correct terminology in my searches. Hope I did a good job of describing the problem. TIA.

  • NHibernate query against the key field of a dictionary (map)

    - by Carl Raymond
    I have an object model where a Calendar object has an IDictionary<MembershipUser, Perms> called UserPermissions, where MembershipUser is an object, and Perms is a simple enumeration. This is in the mapping file for Calendar as <map name="UserPermissions" table="CalendarUserPermissions" lazy="true" cascade="all"> <key column="CalendarID"/> <index-many-to-many class="MembershipUser" column="UserGUID" /> <element column="Permissions" type="CalendarPermission" not-null="true" /> </map> Now I want to execute a query to find all calendars for which a given user has some permission defined. The permission is irrelevant; I just want a list of the calendars where a given user is present as a key in the UserPermissions dictionary. I have the username property, not a MembershipUser object. How do I build that using QBC (or HQL)? Here's what I've tried: ISession session = SessionManager.CurrentSession; ICriteria calCrit = session.CreateCriteria<Calendar>(); ICriteria userCrit = calCrit.CreateCriteria("UserPermissions.indices"); userCrit.Add(Expression.Eq("Username", username)); return calCrit.List<Calendar>(); This constructed invalid SQL -- the WHERE clause contained WHERE membership1_.Username = @p0 as expected, but the FROM clause didn't include the MemberhipUsers table. Also, I really had to struggle to learn about the .indices notation. I found it by digging through the NHibernate source code, and saw that there's also .elements and some other dotted notations. Where's a reference to the allowed syntax of an association path? I feel like what's above is very close, and just missing something simple.

  • How to report progress of a JavaScript function?

    - by LambyPie
    I have a JavaScript function which is quite long and performs a number of tasks, I would like to report progress to the user by updating the contents of a SPAN element with a message as I go. I tried adding document.getElementById('spnProgress').innerText = ... statements throughout the function code. However, whilst the function is executing the UI will not update and so you only ever see the last message written to the SPAN which is not very helpful. My current solution is to break the task up into a number of functions, at the end of each I set the SPAN message and then "trigger" the next one with a window.setTimeout call with a very short delay (say 10ms). This yields control and allows the browser to repaint the SPAN with the updated message before starting the next step. However I find this very messy and difficult to follow the code, I'm thinking there must be a better way. Does anyone have any suggestions? Is there any way to force the SPAN to repaint without having to leave the context of the function? Thanks

  • jQuery > Update inline script on form submission

    - by Andrew Kirk
    I am using the ChemDoodle Web Components to display molecules on a web page. Basically, I can just insert the following script in my page and it will create an HTML5 canvas element to display the molecule. <script> var transform1 = new TransformCanvas('transform1', 200, 200, true); transform1.specs.bonds_useJMOLColors = true; transform1.specs.bonds_width_2D = 3; transform1.specs.atoms_useJMOLColors = true; transform1.specs.atoms_circles_2D = true; transform1.specs.backgroundColor = 'black'; transform1.specs.bonds_clearOverlaps_2D = true; transform1.loadMolecule(readPDB(molecule)); </script> In this example, "molecule" is a variable that I have defined in an external script by using the jQuery.ajax() function to load a PDB file. This is all fine and good. Now, I would like to include a form on the page that will allow a user to paste in a PDB molecule definition. Upon submitting the form, I want to update the "molecule" variable with the form data so that the ChemDoodle Web Components script will work its magic and display molecule defined by the PDB definition pasted into the form. I am using the following jQuery code to process the the form submission. $(".button").click(function() { // validate and process form here //hide previous errors $('.error').hide(); //validate pdb textarea field var pdb = $("textarea#pdb").val(); if (pdb == "") { $("label#pdb_error").show(); $("textarea#pdb").focus(); return false; } molecule = pdb; }); This code is setting the "molecule" variable upon the form submission but it is not being passed back to the inline script as I had hoped. I have tried a number of variations on this but can't seem to get it right. Any clues as to where I might be going wrong would be much appreciated.

  • what use does the javascript forEach method have (that map can't do)?

    - by JohnMerlino
    Hey all, The only difference I see in map and foreach is that map is returning an array and foreach is not. However, I don't even understand the last line of the foreach method "func.call(scope, this[i], i, this);". For example, isn't "this" and "scope" referring to same object and isn't this[i] and i referring to the current value in the loop? I noticed on another post someone said "Use forEach when you want to do something on the basis of each element of the list. You might be adding things to the page, for example. Essentially, it's great for when you want "side effects". I don't know what is meant by side effects. Array.prototype.map = function(fnc) { var a = new Array(this.length); for (var i = 0; i < this.length; i++) { a[i] = fnc(this[i]); } return a; } Array.prototype.forEach = function(func, scope) { scope = scope || this; for (var i = 0, l = this.length; i < l; i++) func.call(scope, this[i], i, this); } Finally, are there any real uses for these methods in javascript (since we aren't updating a database) other than to manipulate numbers like this: alert([1,2,3,4].map(function(x){ return x + 1})); //this is the only example I ever see of map in javascript. Thanks for any reply.

    I have simple class Track, which stores information about route: import java.io.Serializable; import java.util.ArrayList; import java.util.Date; import android.location.Location; public class Track implements Serializable { private static final long serialVersionUID = -5317697499269650204L; private Date date; private String name; private int time; private double distance, speed; private ArrayList<Location> route; public Track(String name, int time, double distance, ArrayList<Location> route) { this.date = new Date(); this.name = name; this.time = time; this.distance = distance; this.speed = distance / (time / 3600.); this.route = route; } public String getDate() { return String.format("Date: %1$td-%1$tb-%1$tY%nTime: %1$tH:%1$tM:%1$tS", date); } public String getName() { return name; } public int getTime() { return time; } public double getDistance() { return distance; } public float getSpeed() { return (float) speed; } public ArrayList<Location> getRoute() { return route; } @Override public String toString() { return String.format("Name: %s%nDate: %2$td-%2$tb-%2$tY%nTime: %2$tH:%2$tM:%2$tS", name, date); } } And I'm passing it from one activity to another: Intent showTrackIntent = new Intent(TabSavedActivity.this, ShowTrackActivity.class); showTrackIntent.putExtra("track", adapter.getItem(position)); startActivity(showTrackIntent); Where (Track object is element on ListView). I get error during passing Track object: java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = classes.Track) What is happening?

  • Hashtable is that fast

    - by Costa
    Hi s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]. Is the hash function of the java string, I assume the rest of languages is similar or close to this implementation. If we have hash-Table and a list of 50 elements. each element is 7 chars ABCDEF1, ABCDEF2, ABCDEF3..... ABCDEFn If each bucket of hashtable contains 5 strings (I think this function will make it one string per bucket, but let us assume it is 5). If we call col.Contains("ABCDEFn"); // will do 6 comparisons and discover the difference on the 7th. The hash-table will take around 70 operations (multiplication and additions) to get the hashcode and to compare with 5 strings in bucket. and BANG it found. For list it will take around 300 comparisons to find it. for the case that there is only 10 elements, the list will take around 70 operations but the Hashtable will take around 50 operations. and note that hashtable operations are more time consuming (it is multiplications). I conclude that HybirdDictionary in .Net probably is the best choice for that most cases that require Hashtable with unknown size, because it will let me use a list till the list becomes more than 10 elements. still need something like HashSet rather than a Dictionary of keys and values, I wonder why there is no HybirdSet!! So what do u think? Thanks

  • Stop scrolling to ID when opening jQuery Modal via URL

    - by markedup
    I need to be able to open an ID'd jQuery UI Modal on a page when that modal's ID is passed in the page's URL. For example: http://mysite.com/visit.html#directions #directions is an ID'd DIV at the very bottom of the page, right before the closing BODY element. It's instantiated as a jQuery UI dialog on page load, then I'm running a function to check the current URL for the modal's ID. If the URL contains the modal's ID, the modal is opened. Here's what my auto-open function looks like: function autoOpenModal() { if ( document.location.href.indexOf('#') ) { var uriParts = document.location.href.split('#'); var hashID = '#' + uriParts[1]; if ( $(hashID) && $(hashID).hasClass('dialog')) { $(hashID).dialog('open'); } } } The problem I'm having is that the browser is automatically scrolling down to the ID at the very bottom of the page before the modal is opened. So when the user closes the modal they're at the bottom of the page (which seems "broken" to me). Can anyone tell me how I stop the browser from auto-scrolling down to the ID please? I've had a look at event.preventDefault() but without success; I'm not sure where or how to use it in the event chain.
