  • PHP: How to find most used array key?

    - by oni-kun
    Lets say I have a simple 1D array with 10-20 entries. Some will be duplicate, How would I find out which entry is used the most? like.. $code = Array("test" , "cat" , "test" , "this", "that", "then"); How would I show "test" as the most used entry?

  • IE won't load PDF in a window created with window.open

    - by Dean
    Here's the problem, which only occurs in Internet Explorer (IE). I have a page that has links to several different types of files. Links from these files execute a Javascript function that opens a new window and loads the specific file. This works great, unless the file I need to open in the new window is a PDF in which case the window is blank, even though the URL is in the address field. Refreshing that window using F5 doesn't help. However, if I put the cursor in the address field and press <enter> the PDF loads right up. This problem only occurs in IE. I have seen it in IE 7 and 8 and am using Adobe Acrobat Reader 9. In Firefox (PC and Mac) everything works perfectly. In Chrome (Mac), the PDF is downloaded. In Safari (Mac) it works. In Opera (Mac) it prompts me to open or save. Basically, everything probably works fine, except for IE. I have searched for similar problems and have seen some posts where it was suggested to adjust some of the Internet Options on IE. I have tried this but it doesn't help, and the problem wasn't exactly the same anyway. Here's the Javascript function I use to open the new window. function newwin(url,w,h) { win = window.open(url,"temp","width="+w+",height="+h+",menubar=yes,toolbar=yes,location=yes,status=yes,scrollbars=auto,resizable=yes"); win.focus(); } You can see that I pass in the URL as well as the height, h, and width, w, of the window. I've used a function like this for years and as far as I know have never had a problem. I call the newwin() function using this. <a href="javascript:newwin('/path/document.pdf',400,300)">document.pdf</a> (Yes, I know there are other, better ways than using inline JS, and I've even tried some of them because I've run out of things to try, but nothing works.) So, if anyone has an idea as to what might be causing this problem, I'd love to hear it.

  • Drawing Bresenham’s Line- Algorithm in all quadrants

    - by Yoyo2965259
    I am newbie for OpenGL. I am practicing the exercises from my textbook but I could not get the outputs which is should be in Bresenham's Line Algorithm in all quadrants.

  • css table column width not set

    - by bsreekanth
    Hello, I'm trying to set the width of table column to a minimum value. The header row (th) was set white-space:nowrap to prevent wrapping. Now all the columns (including td rows) set to a width that of th. I tried to expand the size of smaller columns by setting it in the html as <th style="width:200px;"> and <td style="width:200px;">, but it has no effect. In firebug, in the style section, the width setting is active element.style { width:200px; } Still, the computed tab shows the width is less than 200px. Please see the details below. th -- computed: Text font-family verdana,arial,helvetica,sans-serif font-size 10px font-weight bold font-style normal color #333333 text-transform none text-decoration none letter-spacing normal word-spacing 0 line-height 17px text-align left vertical-align baseline direction ltr Background background-color transparent background-image none background-repeat repeat background-position 0 0 background-attachment scroll opacity 1 Box Model width 152px height 17px top auto right auto bottom auto left auto margin-top 0 margin-right 0 margin-bottom 0 margin-left 0 padding-top 0 padding-right 0 padding-bottom 0 padding-left 0 border-top-width 0 border-right-width 0 border-bottom-width 0 border-left-width 0 border-top-color #333333 border-right-color #333333 border-bottom-color #333333 border-left-color #333333 border-top-style none border-right-style none border-bottom-style none border-left-style none Layout position static display block visibility visible z-index auto overflow-x visible overflow-y visible white-space nowrap clip auto float none clear none -moz-box-sizing content-box Other cursor pointer list-style-image none list-style-position outside list-style-type disc marker-offset auto and td --computed: Text font-family verdana,arial,helvetica,sans-serif font-size 11px font-weight 400 font-style normal color #222222 text-transform none text-decoration none letter-spacing normal word-spacing 0 line-height 12px text-align left vertical-align top direction ltr Background background-color transparent background-image none background-repeat repeat background-position 0 0 background-attachment scroll opacity 1 Box Model width 152px height 48px top auto right auto bottom auto left auto margin-top 0 margin-right 0 margin-bottom 0 margin-left 0 padding-top 5px padding-right 6px padding-bottom 5px padding-left 6px border-top-width 0 border-right-width 1px border-bottom-width 0 border-left-width 0 border-top-color #222222 border-right-color #222222 border-bottom-color #222222 border-left-color #DDDDDD border-top-style none border-right-style none border-bottom-style none border-left-style solid Layout position static display table-cell visibility visible z-index auto overflow-x visible overflow-y visible white-space normal clip auto float none clear none -moz-box-sizing content-box Other cursor auto list-style-image none list-style-position outside list-style-type disc marker-offset auto Any help, highly appreciated... thanks

  • Cant full read querystring data in mvc4 application using a class array as input to action

    - by Anders Lindén
    I have made a mvc4 application and I have a Controller that outputs a png file like this: using System.Drawing; using System.Drawing.Drawing2D; using System.Drawing.Imaging; using System.Drawing.Text; using System.IO; using System.Web.Mvc; using Foobar.Classes; namespace Foobar.Controllers { public class ImageController : Controller { public ActionResult Index(Label[] labels) { var bmp = new Bitmap(400, 300); var pen = new Pen(Color.Black); var font = new Font("arial", 20); var g = Graphics.FromImage(bmp); g.SmoothingMode = SmoothingMode.HighQuality; g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit; if (labels != null) { g.DrawString("" + labels.Length, font, pen.Brush, 20, 20); if (labels.Length > 0) { g.DrawString("" + labels[0].label, font, pen.Brush, 20, 40); } } var stream = new MemoryStream(); bmp.Save(stream, ImageFormat.Png); stream.Position = 0; return File(stream, "image/png"); } } } The Label class looks like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace Foobar.Classes { public class Label { public string label { get; set; } public int fontsize { get; set; } } } When I run my controller having this in the url: http://localhost:57775/image?labels[0][label]=Text+rad+1&labels[0][fontsize]=5&labels[1][fontsize]=5&labels[2][fontsize]=5 I get the correct amount of labels, so the image will show 3. But the instances of Label will not get its data members fill in. I have also tried to do this using plain variables (not properties). If they were filled in, the image would actually show "3" and "Text rad 1". So what do I put in the class "Label" to have the properties right? Should there be some kind of annotation? Where do I read about this?

  • Can't override a global WPF style that is set by TargetType on a single specific control

    - by Matt H.
    I have a style applied to all my textboxes, defined in a resource dictionary.. <Style TargetType="TextBlock"> <Setter Property="TextBlock.FontSize" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontSize, Mode=OneWay}" /> <Setter Property="TextBlock.TextWrapping" Value="Wrap" /> <Setter Property="TextBlock.VerticalAlignment" Value="Center"/> <Setter Property="Background" Value="Transparent"/> <Setter Property="TextBox.FontFamily" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontName, Mode=OneWay}"/> </Style>\ The fontsize and fontstyle properties are bound to a special user settings class that implements iNotifyPropertyChanged, which allows changes to font size and fontfamily to immediately propogate throughout my application. However, in a UserControl I've created (Ironically, the screen that allows the user to customize their font settings), I want the font size and fontfamily to remain static. No matter what I try, my global font settings override what I set in my user control: <UserControl x:Class="ctlUserSettings" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:R2D2" Height="400" Width="600"> <Grid> <Grid.Resources> <Style x:Key="tbxStyle" TargetType="TextBox"> <Style.Setters> <Setter Property="FontSize" Value="14"/> <Setter Property="FontFamily" Value="Tahoma"/> </Style.Setters> </Style> ... etc... <StackPanel Margin="139,122.943,41,0" Orientation="Horizontal" Height="33" VerticalAlignment="Top"> <TextBox Style="{x:Null}" FontSize="13" FontFamily="Tahoma" HorizontalAlignment="Left" MaxWidth="500" MinWidth="350" Name="txtReaderPath" Height="Auto" VerticalAlignment="Top" /> <TextBox Style="{x:tbxStyle}" Margin="15,0,0,0" HorizontalAlignment="Left" Name="txtPath" Width="43" Height="23" VerticalAlignment="Top">(some text)</Button> </StackPanel> I've tried setting Style to {x:Null}, setting custom font sizes inline, and setting a style in the resources of this control. None take precedence over the styles in my resource dictionary. As you can see, I show a sprinkling of all the things I've tried in the XAML sample above... What am I missing?

  • jQuery / javascript and nested if statements

    - by rayne
    I have a multi-lingual page where I want to display form validation error in the user's language. I use a hidden input to determine which language version the user is browsing like this: <input type="hidden" name="lang" id="lang" value="<?php echo $lang; ?>" /> The PHP side of the script works, but jQuery doesn't seem to realize which language is passed on. It displays the English error message no matter on which language site I am. Here's the code (I removed the other form fields for length): $(document).ready(function(){ $('#contact').submit(function() { $(".form_message").hide(); var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var lang = $("#lang").val(); var name = $("#name").val(); var dataString = { 'lang': lang, 'name': name } if (name == '') { if (lang == 'de') { $("#posted").after('<div class="form_message"><p><span class="error">Fehler:</span> Bitte gib deinen Namen an!</p></div>'); } else { $("#posted").after('<div class="form_message"><p><span class="error">Error:</span> Please enter your name!</p></div>'); } $("#name").focus(); $("#name").addClass('req'); } else { $("#loading").show(); $("#loading").fadeIn(400).html('<img src="/img/loading.gif" />Loading...'); $.ajax({ type: "POST", url: "/contact-post.php", data: dataString, cache: false, success: function(html){ $("#loading").hide(); $("#posted").after('<div class="form_message"><p>Thank you! Your contact request has been sent.</p></div>'); $("#contact input:submit").attr("disabled", "disabled").val("Success!"); } }); }return false; }); }); The problem seems to be somewhere in the nested if statement. Does jQuery / javascript even recognize nested ifs? And if yes, why is it not working?

  • understanding logic of dijit css and styles

    - by Tom
    Hi, I am trying to use dijit.InlineEditBox. I have put the following code in my HTML, using the example in the dojo docs: <script type="text/javascript"> dojo.require("dijit.InlineEditBox"); dojo.require("dojo.parser"); dojo.require("dijit.form.TextBox"); function editableHeaderOnChange(id, arg){ alert("details changed with id " + id + " and arguments "+arg); } </script> ... <span id="myText" dojoType="dijit.InlineEditBox" onChange="editableHeaderOnChange(this.id,arguments[0])" autoSave="true" title="My Text">click to edit me</span> I am using tundra theme. It works, however it doesn't look so good. The widget has its own style, which doesn't fit my CSS. I used firebug to locate the source of the problem. The widget creates many nested div/span elements, each has it's own style (element style in firebug): <span id="dijit__InlineEditor_0" class="dijitReset dijitInline" style="margin: 0px; position: absolute; visibility: hidden; display: block; opacity: 0;" ...> <input type="text" autocomplete="off" class="dijit dijitReset dijitLeft dijitTextBox" id="dijit_form_TextBox_0" style="line-height: 20px; font-weight: 400; font-family: Trebuchet MS,Helvetica,Arial,Verdana; font-size: 14.5167px; font-style: normal; width: 100%;"> ...> </span></span> (showing only the relevant parts...) to get the visual that I want, which will not break to a newline, I need to change the width of dijit_form_TextBox_0** to 50%, and the positioning of dijit__InlineEditor_0 to display: inline**; or to change the positioning of everything (most of my layout is floated, so position: absolute doesn't fit) I cannot address those span elements in my css to change the properties, because the element.style has priority, of course. I don't understand the logic in this system... why is dijit generating the style directly inside the element? how can I change these properties? Thanks Tom

  • Regex for finding an unterminated string

    - by Austin Hyde
    I need to search for lines in a CSV file that end in an unterminated, double-quoted string. For example: 1,2,a,b,"dog","rabbit would match whereas 1,2,a,b,"dog","rabbit","cat bird" 1,2,a,b,"dog",rabbit would not. I have very limited experience with regular expressions, and the only thing I could think of is something like "[^"]*$ However, that matches the last quote to the end of the line. How would this be done?

  • How to access a named element in a control that inherits from a templated control

    - by Mrt
    Hello this is similar to http://stackoverflow.com/questions/2620165/how-to-access-a-named-element-of-a-derived-user-control-in-silverlight with the difference is inheriting from a templated control, not a user control. I have a templated control called MyBaseControl <Style TargetType="Problemo:MyBaseControl"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Problemo:MyBaseControl"> <Grid x:Name="LayoutRoot" Background="White"> <Border Name="HeaderControl" Background="Red" /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> public class MyBaseControl : Control { public UIElement Header { get; set; } public MyBaseControl() { DefaultStyleKey = typeof(MyBaseControl); } public override void OnApplyTemplate() { base.OnApplyTemplate(); var headerControl = GetTemplateChild("HeaderControl") as ContentPresenter; if (headerControl != null) headerControl.Content = Header; } } I have another control called myControl which inherits from MyBaseControl Control <me:MyBaseControl x:Class="Problemo.MyControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:me="clr-namespace:Problemo" d:DesignHeight="300" d:DesignWidth="400"> <me:MyBaseControl.Header> <TextBlock Name="xxx" /> </me:MyBaseControl.Header> </me:MyBaseControl> public partial class MyControl : MyBaseControl { public string Text { get; set; } public MyControl(string text) { InitializeComponent(); Text = text; Loaded += MyControl_Loaded; } void MyControl_Loaded(object sender, RoutedEventArgs e) { base.ApplyTemplate(); xxx.Text = Text; } } The issue is xxx is null.

  • Window Media Player issues two requests for the audio on web page

    - by Ron Harlev
    I'm using Windows Media Player in a web page. I have version 11 installed so that is the version I'm testing with right now. The player is embedded on the page with this HTML: <OBJECT id='MS_mediaPlayer' width="400" height="45" classid='CLSID:6BF52A52-394A-11D3-B153-00C04F79FAA6' codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701' standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'> <param name='autoStart' value="false"> <param name='uiMode' value="invisible"> <param name='loop' value="false"> </OBJECT> I'm calling in JavaScript: MS_mediaPlayer.URL = "SomeAudioFile.mp3" MS_mediaPlayer.controls.play(); When I look at Fiddler I can see that the player actually downloads "SomeAudioFile.mp3" twice. Is there some setting I have wrong? I was trying to set the "autoPlay" to true and avoid calling "play()". Got the same result - two downloads. UPDATE: The first request's user-agent is "Windows-Media-Player/11.0.5721.5268". The second has "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB6; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)". Looks like the browser is running the same request the second time. No Idea why Any ideas? UPDATE (4/1/10): Still no solution. I debugged the JS thoroughly and there is only one call to MediaPlayer.URL='.....' to set the audio file. Nothing else triggers the media player to load the file and there is no other place referencing the audio file on the page. One other interesting fact is that this doesn't happen (the double loading of the audio) when I run the browser locally on my development web server. But other remote requests to the same web server generate the double audio loading. I believe I eliminated any correlation with specific IE version or media player version. This happens with IE6-8 and WM9-12

  • Jquery Dialog - div disappears after initialization

    - by Zuber
    JQuery Dialog is giving me lots of pain lately. I have the following div which I want to be popped up. (Ignore that the classes do not show the double quotes in the syntax) TABLE class=widget-title-table border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD class=widget-title><SPAN class=widget-title>Basic Info</SPAN></TD> <TD class=widget-action> <DIV id=edit-actions jQuery1266325647362="3"> <UL class="linkbutton-menu read-mode"> <LI class="control-actions"> <A id="action-button" class="mouse-over-pointer linkbutton">Delete this stakeholder</A> <DIV id="confirmation" class="confirmation-dialog title=Confirmation"> Are you sure you want to delete this stakeholder? </DIV> </LI></UL></DIV></TD></TR></TBODY></TABLE> The JQuery for this is ... $(document).ready(function() { $('#confirmation').dialog({ bgiframe: true, modal: true, autoOpen: false, closeOnEscape: false, draggable: true, position: 'center', resizable: false, width: 400, height: 150 }); }); And the dialog is 'open'ed by var confirmationBox = $('#confirmation',actionContent); if (confirmationBox.length > 0) { //Confirmation Needed $(confirmationBox).dialog('option', 'buttons', { 'No': function() { $(this).dialog('close'); }, 'Yes': function() { $('ul.read-mode').hide(); $.post(requestUrl, {}, ActionCallback(context[0], renderFormUrl), 'json'); $(this).dialog('close'); } }); $(confirmationBox).dialog('open'); } The problem starts in the initialization itself. When the document loads, the <div #confirmation> is deleted from the markup! I had a similar issue earlier, but I cannot use that solution here. On this page I can have multiple PopUp divs. When I added the initialization in just before opening it; the form popped up. But after I close it, the div is removed; so I am not able to see the popup again.

  • Flex - Problem with auto resizing datagrid

    - by Marty Pitt
    Hi All I'm trying to create a datagrid which will resize vertically to ensure all the renderers are displayed in full. Additionally, Renderers are of variable height Renderers can resize themselves Generally speaking, the flow of events is as follows : One of the item renderers resizes itself (normally in response to a user click etc) It dispatches a bubbling event which the parent datagrid picks up The DataGrid attempts to resize to ensure that all renderers remain visible in full. I'm currently using this code within the datagrid to calculate the height: height = measureHeightOfItems(0, dataProvider.length ) + headerHeight; This appears to get an incorrect height. I've tried a number of variations including callLater ( to ensure the resize has completed so measure can work correctly), and overriding meausre() and calling invalidateSize() / validateSize(), but neither works. Below are 3 classes which will illustrate the problem. Clicking the button in the item renderers resizes the renderer. The grid should also expand so that all of the 3 renderers are shown in their entirety. Any suggestions would be greatly appreciated. Regards Marty DataGridProblem.mxml (Application file) <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" xmlns:view="view.*"> <mx:ArrayCollection id="dataProvider"> <mx:String>Item A</mx:String> <mx:String>Item B</mx:String> <mx:String>Item C</mx:String> </mx:ArrayCollection> <view:TestDataGrid id="dg" dataProvider="{ dataProvider }" width="400"> <view:columns> <mx:DataGridColumn dataField="text" /> <mx:DataGridColumn itemRenderer="view.RendererButton" /> </view:columns> </view:TestDataGrid> </mx:Application> view.TestDataGrid.as package view { import flash.events.Event; import mx.controls.DataGrid; import mx.core.ScrollPolicy; public class TestDataGrid extends DataGrid { public function TestDataGrid() { this.verticalScrollPolicy = ScrollPolicy.OFF; this.variableRowHeight = true; this.addEventListener( RendererButton.RENDERER_RESIZE , onRendererResize ); } private function onRendererResize( event : Event ) : void { resizeDatagrid(); } private function resizeDatagrid():void { height = measureHeightOfItems(0, dataProvider.length ) + headerHeight; } } } view.RendererButton.mxml <?xml version="1.0" encoding="utf-8"?> <mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Button width="50" height="50" click="onClick()" /> <mx:Script> <![CDATA[ public static const RENDERER_RESIZE : String = "resizeRenderer"; private function onClick() : void { this.height += 20; dispatchEvent( new Event( RENDERER_RESIZE , true ) ); } ]]> </mx:Script> </mx:HBox>

Thanks Here is the code of the controller I am using, all I am trying to do is register a user with reCaptcha functionality but what I am getting is a http status 400 with the error org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'recaptcha_challenge_field' is not present: UserManagementController.java @Controller public class UserManagementController { private static final String RECAPTCHA_HTML = "reCaptchaHtml"; @Autowired private UserService userService; @Autowired private ReCaptcha reCaptcha; @RequestMapping(method=RequestMethod.GET, value="/addNewUser.do") public ModelAndView addNewUser() { User user = new User(); String html = reCaptcha.createRecaptchaHtml(null, null); ModelMap modelMap = new ModelMap(); modelMap.put("user", user); modelMap.put(RECAPTCHA_HTML, html); return new ModelAndView("/addNewUser", modelMap); } @RequestMapping(method=RequestMethod.POST, value="/addNewUser.do") public String addNewUser(@Valid User user, BindingResult result, @RequestParam("recaptcha_challenge_field") String challenge, @RequestParam("recaptcha_response_field") String response, HttpServletRequest request, Model model) { verifyBinding(result); String remoteAddr = request.getRemoteAddr(); ReCaptchaResponse reCaptchaResponse = reCaptcha.checkAnswer(remoteAddr, challenge, response); if (!reCaptchaResponse.isValid()) { result.rejectValue("captcha", "errors.badCaptcha"); } model.addAttribute("user", user); if (result.hasErrors()) { result.reject("form.problems"); return "addNewUser"; } return "redirect:showContent.do"; } @InitBinder public void initBinder(WebDataBinder binder) { binder.setAllowedFields(new String[] { "firstName", "lastName", "email", "username", "password", "recaptcha_challenge_field", "recaptcha_response_field" }); } private void verifyBinding(BindingResult result) { String[] suppressedFields = result.getSuppressedFields(); if (suppressedFields.length > 0) { throw new RuntimeException("You've attempted to bind fields that haven't been allowed in initBinder(): " + StringUtils.join(suppressedFields, ", ")); } } } Here is the addNewUser.jsp element on the form page for the above controller: <tr> <td>Please prove you're a person</td> <td>${reCaptchaHtml}</td> <td><form:errors path="captcha" cssStyle="color:red"></form:errors></td> </tr> Could you help me understand what am I missing here? Thanks for reply.

  • What to do when you need more verbs in REST

    - by Richard Levasseur
    There is another similar question to mine, but the discussion veered away from the problem I'm encounting. Say I have a system that deals with expense reports (ER). You can create and edit them, add attachments, and approve/reject them. An expense report might look like this: GET /er/1 => {"title": "Trip to NY", "totalcost": "400 USD", "comments": [ "john: Please add the total cost", "mike: done, can you approve it now?" ], "approvals": [ {"john": "Pending"}, {"finance-group": "Pending"}] } That looks fine, right? Thats what an expense report document looks like. If you want to update it, you can do this: POST /er/1 {"title": "Trip to NY 2010"} If you want to approve it, you can do this: POST /er/1/approval {"approved": true} But, what if you want to update the report and approve it at the same time? How do we do that? If you only wanted to approve, then doing a POST to something like /er/1/approval makes sense. We could put a flag in the URL, POST /er/1?approve=1, and send the data changes as the body, but that flag doesn't seem RESTful. We could put special field to be submitted, too, but that seems a bit hacky, too. If we did that, then why not send up data with attributes like set_title or add_to_cost? We could create a new resource for updating and approving, but (1) I can't think of how to name it without verbs, and (2) it doesn't seem right to name a resource based on what actions can be done to it (what happens if we add more actions?) We could have an X-Approve: True|False header, but headers seem like the wrong tool for the job. It'd also be difficult to get set headers without using javascript in a browser. We could use a custom media-type, application/approve+yes, but that seems no better than creating a new resource. We could create a temporary "batch operations" url, /er/1/batch/A. The client then sends multiple requests, perhaps POST /er/1/batch/A to update, then POST /er/1/batch/A/approval to approve, then POST /er/1/batch/A/status to end the batch. On the backend, the server queues up all the batch requests somewhere, then processes them in the same backend-transaction when it receives the "end batch processing" request. The downside with this is, obviously, that it introduces a lot of complexity. So, what is a good, general way to solve the problem of performing multiple actions in a single request? General because its easy to imagine additional actions that might be done in the same request: Suppress or send notifications (to email, chat, another system, whatever) Override some validation (maximum cost, names of dinner attendees) Trigger backend workflow that doesn't have a representation in the document.

  • How can I position some divs inside an unordered list so they line up with the root element of the l

    - by Ronedog
    I want to position all the divs to line up to the left on the same x coordinate so it looks nice. Notice the picture below, how based on the number of nested categories the div (and its contents) show up at slightly different x coordinates. I need to have the div's line up at exactly the same x coordinate no matter how deeply nested. Note, the bottom most category always has a div for the content, but that div has to be situated inside the last < li . I am using an unordered list to display the menu and thought the best solution would be to grab the root category (Cat 2, and mCat1) and obtain their left offset using jquery, then simply use that value to update the positioning of the div...but I couldn't seem to get it to work just right. I would appreciate any advice or help that you are willing to give. Heres the HTML <ul id="nav> <li>Cat 2 <ul> <li>sub cat2</li> </ul> </li> <li>mCat1 <ul> <li>Subcat A <ul> <li>Subcat A.1 <ul> <li>Annie</li> </ul> </li> </ul> </li> </ul> </li> </ul> Heres some jquery I tried (I have do insert the div inside this .each() loop in order to retrieve some values, but basically, this selector is grabbing the last < li in the menu tree and placing a div after it and that is the div that I want to position. the 245 value was something I was playing around with to see how I could get things to line up, and I know its out of wack, but the problem is still the same no matter what I do: $("#nav li:not(:has(li))").each(function () { var self = $(this); var position = self.offset(); var xLeft = Math.round(position.left)- 245; console.log("xLeft:", xLeft ); self.after( '<div id="' + self.attr('p_node') + '_p_cont_div" class="property_position" style="display:none; left:' + xLeft + 'px;" /> ' ); }); Heres the css: .property_position{ float:left; position: relative; top: 0px; padding-top:5px; padding-bottom:10px; }
