  • Sharing variable within different javascript file at client side

    - by Aman
    I was actually going through this link. which explains how we can share global variable across multiple js. but the point is what need to be done if I am getting some variable into one js and need to pass to another one mentioned in same document after the 1st one. approach which followed was: Script 1 <script type="text/javascript" src="js/client.js"></script> body added some hidden input with id myHiddenId, where values are set using client.js Script 2 <script type="text/javascript" src="js/anotherJS.js"></script> inside script 2 I am simply using $("#myHiddenId").val(); and using for my purpose. I want to know whether I am following correct approach, because that hidden field may have some data which client should not get aware of. is there any other way through which I can pass the variable values across the js files ? Since I am at beginner level hence digging up some resources/books but still no luck.

    - by mustanggal511
    I'm trying to save a UIImageView image to a png file, and then use that file as a GLTexture. I'm having trouble with this, when I try to run my code in the simulator, XCode says it succeeded, but the simulator crashes with no error messages. Can someone help me with this? Here is my code: NSString *dataFilePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Picture.png"]; NSData *imageData = UIImagePNGRepresentation(imageView.image); [imageData writeToFile:dataFilePath atomically:YES]; // Load image into texture loadTexture("Picture.png", &Input, &renderer);

  • Loop colours from variables for graphics.py [Python 3.2]

    - by user1056548
    I am creating a graphics program that draws 100 x 100 squares next to each other depending on the user-specified grid size. The user also inputs 4 colours for the squares to be coloured (e.g. if they enter red,green,blue,yellow the squares will be coloured in that order, repeating the colours). Is it possible to loop the colours from the variables the user has given? Here is what I have so far: def main(): print ("Please enter four comma seperated colours e.g.: 'red,green,blue,yellow'\n\ Allowed colours are: red, green, blue, yellow and cyan") col1, col2, col3, col4 = input("Enter your four colours: ").split(',') win = GraphWin ("Squares", 500, 500) colours = [col1, col2, col3, col4] drawSquare (win, col1, col2, col3, col4, colours) win.getMouse() win.close() def drawSquare(win, col1, col2, col3, col4, colours): for i in range (4): for j in range (len(colours)): colour = colours[j] x = 50 + (i * 50) circle = Circle (Point (x,50), 20) circle.setFill(colour) circle.draw(win) I think I should be using a list in some way, but can't work out exactly how to do it. Can anybody help?

  • rails - Redirecting console output to a file

    - by egarcia
    On a bash console, if I do this: cd mydir ls -l > mydir.txt The operator captures the standard input and redirects it to a file; so I get the listing of files in mydir.txt instead of in the standard output. Is there any way to do something similar on the rails console? I've got a ruby statement that generates lots of prints (~8k lines) and I'd like to be able to see it completely, but the console only "remembers" the last 1024 lines or so. So I thought about redirecting to a file - If anyone knows a better option, I'm all ears.

  • CakePHP - radio button not showing error message

    - by teepusink
    Hi, I'm unable to get the error message to show up when creating a radio form using the CakePHP form helper. This is what I have now. $options=array('active'=>'Active','inactive'=>'Inactive'); echo $form->input('Status', array( 'type' => 'radio', 'id' => 'EntryStatus', 'name' => 'data[Entry][status]', 'options' => $options )); What am I missing? I'm using CakePHP 1.2.7 and this is what I have in the validation 'status' = array( 'notempty' = array( 'rule' = 'notempty', 'required' = true, 'message' = 'yo' ) ) Tried the answer from http://stackoverflow.com/questions/1388823/form-helper-for-creating-radio-button-in-cakephp and it's giving me a select option form instead. Thanks, Tee

  • MySQL import in phpmyadmin (CSV) chokes on quotes

    - by Andrew Swift
    I am trying to import a .csv file into a MySQL table via phpMyAdmin. The .csv file is separated by pipes, formated like this: data|d'ata|d'a"ta|dat"a| data|"da"ta|data|da't'a| dat'a|data|da"ta"|da'ta| The data contains quotes. I have no control over the format in which I recieve the data -- it is generated by a third party. The problem comes when there is a | followed by a double quote. I always get an "invalid field count in CSV input on line N" error. I am uploading the file from the import page, using Latin1, CSV, terminated by |, separated by ". I would like to just change the "enclosed by" character, but I keep getting "Invalid parameter for CSV import: Fields enclosed by". I have tried various characters with no success. How can I tell MySQL to accept this format in phpMyAdmin? Setting up these tables is the first step in writing a program that will use uploaded gzipped .csv files to maintain the catalog of an e-commerce site.

  • Debugging "Incorrect Syntax" Exception

    - by MattH
    I have recently been working with a COM+ component that processes an input XML file, and makes a number of database updates based on the supplied data. Running SQL Profiler with EventClass Exception, and User Error Message selected, I see: Exception Error: 102, Severity: 15, State: 1 User Error Message Incorrect syntax near '3'. However I really want to see the full SQL that is being supplied by the COM+ component. Is there anyway for me using Profiler, or other, for me to intercept the SQL statement that was sent to the SQL Server? This machine is using SQL Server 2005, and the COM+ object is written in Delphi.

  • How to store and access ajax data in javascript without using global variables ?

    - by mike_t2e
    I may be missing something obvious here, but how could I rewrite this code so that it doesn't need the theVariable to be a global variable ? <script language="javascript"> theVariable = ""; function setValue() /* called on page load */ { /* make ajax call to the server here */ theVariable = "a string of json data waiting to be eval()'d"; } function getValue() { alert(theVariable); } </script> <input type="button" onClick="javascript:getValue()" value="Get the value"> In my actual situation, the setValue function makes an ajax call to the server, receives a json string and the data from that is accessed when you mouseover various parts of the page. I end up using several global variables which works fine, but is messy and I'd like to know if there's a better and more elegant way of doing it ?

  • How do I draw a filled circle onto a graphics object in a hexadecimal colour?

    - by George Powell
    I need to draw a circle onto a bitmap in a specific colour given in Hex. The "Brushes" class only gives specific colours with names. Bitmap bitmap = new Bitmap(20, 20); Graphics g = Graphics.FromImage(bitmap); g.FillEllipse(Brushes.AliceBlue, 0, 0, 19, 19); //The input parameter is not a Hex //g.FillEllipse(new Brush("#ff00ffff"), 0, 0, 19, 19); <<This is the kind of think I need. Is there a way of doing this? The exact problem: I am generating KML (for Google earth) and I am generating lots of lines with different Hex colours. The colours are generated mathematically and I need to keep it that way so I can make as many colours as I want. I need to generate a PNG icon for each of the lines that is the same colour exactly.

  • Problem with superfish submenu being trimmed by content in Firefox

    - by da5id
    Greetings, I have a problem which would seem to involve some kind of z-index issue, but for a change it's in everything except IE. If you take a look at http://cougar.motivo.com.au/ in anything except Internet Explorer and hover over the last menu item "Contact Us" you can se what I'm referring to. Basically the supersub menu appears to be being trimmed by the width of the element below it. You can see via the source that I've tried setting z-indexes & position:relative, but at this point I'm stumped. Any and all input would be gratefully received :) P.S. I am aware that there are still a couple of issues in IE6. I am yet to have the pleasure of addressing those (groans).

  • Wordpress comments - perform simple math?

    - by RodeoRamsey
    I have a Wordpress website in which one of the categories I've stripped the comments field down to basic whole numbers only. The logged in user can enter data on the post via the "comments" field, in basic simple whole numbers. Is there any way to take the MOST RECENT comment on all posts from that category (cat 1) and run basic math? My goal is to take the most recent comment's input from each post and add it together and display it via some php/html on another page/post or widget somewhere. Thanks!

  • Fitts Law, applying it to touch screens

    - by Caylem
    Been reading a lot into UI design lately and Fitts Law keeps popping up. Now from what i gather its basically the larger an item is, and the closer it is to your cursor, the easier it is to click on. So what about touch screen devices where the input comes from multiple touches or just single touches. What are the fundamentals to take into account considering this? Should it be something like, the hands of the user are on the sides of the device so the buttons should be close to the left and right hand sides of the device? Thanks

  • Selecting Element followed by text with Selenium WebDriver

    - by Andrew
    I am using Selenium WebDriver and the Python bindings to automate some monotonous WordPress tasks, and it has been pretty straightforward up until this point. I am trying to select a checkbox, but the only way that I can identify it is by the text following it. Here is the relevant portion of HTML: <li id="product_cat-52"> <label class="selectit"> <input value="52" type="checkbox" name="tax_input[product_cat][]" id="in-product_cat-52"> polishpottery </label> </li> The only information that I have in my script to identify this checkbox is the string "polishpottery". Is there any way to select that checkbox knowing only the text that follows?

  • hasErrors with indexed property

    I am having hard time getting hasErrors to work with indexed properties. For example class Order { String prop1 String prop2 static hasMany = [items: Item] } class Item { String name static constraints = { name(blank:false) } } Validation works properly and on item.name being blank I do get an error with <g:renderErrors bean="${orderInstance}"/> However, I am trying to have input box highlighted using hasErrors : <g:each in="${orderIntsance.items}" status="i" var="item"> <span class="field ${hasErrors(bean: orderInstance, field: ????????? , 'errors')}"> <g:textField name="items[${i}].name" value="${item?.name}"/> </span> </g:each> Not sure how to get to it with a field: property, any ideas?

  • jQuery inserting comment help

    - by StealthRT
    Hey all, i am trying to learn how to insert a comment within some html code without having to refresh the page. I know jQuery is capable of inserting a comment into a div area but i am having problems finding an example like that with fading in. Here is my comment code: <div id="CommentBox122" style="width:80%; padding:2px; margin-left:25px;"> <table width="650px" border="0" cellpadding="0" cellspacing="5" style="margin-left:20px; background-color: #F8F8F8; border-bottom:#CCC solid 1px;"><tr> <td width="10%" rowspan="2" align="center" class="Commentimage"><img src="img/avatar/gkrgimmkdhmggfh.jpg" height="60" /></td> <td width="90%" class="Commentposted">Posted by me on Saturday, May 01, 2010 @ 4:37: PM</td></tr> <tr><td class="Commentsaying">this is a test comment</td></tr> </table> <div id="stylized" class="myform" align="center"> <form id="CommentForm122" name="CommentForm122"> <div align="center" style="text-align:center; color:#F00; font-family:Arial, Helvetica, sans-serif; font-weight:bold;">Would you like to leave a comment, Robert?</div> <textarea name="txtComment" class="box" id="txtComment"></textarea> <input name="txtpostid" type="text" id="txtpostid" style="visibility:hidden; display:none; height:0px; width:0px;" value="Demo43639" /> <div class="buttons" align="center"> <button type="button" id="Button122" name="Button122" class="positive" onclick="doStuff();"><img name="Submit" src="img\buttonimgComment.png" alt="" />Post Comment</button> </div> </form> </div> </div> The code i need to insert again would be: <table width="650px" border="0" cellpadding="0" cellspacing="5" style="margin-left:20px; background-color: #F8F8F8; border-bottom:#CCC solid 1px;"><tr> <td width="10%" rowspan="2" align="center" class="Commentimage"><img src="img/avatar/gkrgimmkdhmggfh.jpg" height="60" /></td> <td width="90%" class="Commentposted">Posted by me on Saturday, May 01, 2010 @ 4:37: PM</td></tr> <tr><td class="Commentsaying">this is a test comment</td></tr> </table> But again, i am unable to find an example using jQuery to automatically insert that part of the code under the other "table /table" box.. So after its inserted by jQuery, the code should look like this: <div id="CommentBox122" style="width:80%; padding:2px; margin-left:25px;"> <table width="650px" border="0" cellpadding="0" cellspacing="5" style="margin-left:20px; background-color: #F8F8F8; border-bottom:#CCC solid 1px;"><tr> <td width="10%" rowspan="2" align="center" class="Commentimage"><img src="img/avatar/gkrgimmkdhmggfh.jpg" height="60" /></td> <td width="90%" class="Commentposted">Posted by me on Saturday, May 01, 2010 @ 4:37: PM</td></tr> <tr><td class="Commentsaying">this is a test comment</td></tr> </table> <table width="650px" border="0" cellpadding="0" cellspacing="5" style="margin-left:20px; background-color: #F8F8F8; border-bottom:#CCC solid 1px;"><tr> <td width="10%" rowspan="2" align="center" class="Commentimage"><img src="img/avatar/gkrgimmkdhmggfh.jpg" height="60" /></td> <td width="90%" class="Commentposted">Posted by me on Saturday, May 01, 2010 @ 4:37: PM</td></tr> <tr><td class="Commentsaying">this is a test comment</td></tr> </table> <div id="stylized" class="myform" align="center"> <form id="CommentForm122" name="CommentForm122"> <div align="center" style="text-align:center; color:#F00; font-family:Arial, Helvetica, sans-serif; font-weight:bold;">Would you like to leave a comment, Robert?</div> <textarea name="txtComment" class="box" id="txtComment"></textarea> <input name="txtpostid" type="text" id="txtpostid" style="visibility:hidden; display:none; height:0px; width:0px;" value="Demo43639" /> <div class="buttons" align="center"> <button type="button" id="Button122" name="Button122" class="positive" onclick="doStuff();"><img name="Submit" src="img\buttonimgComment.png" alt="" />Post Comment</button> </div> </form> </div> </div> As always, any help would be great! :o) David

  • qmake -project command gives QFileInfo warning in Qt 4.6

    I've upgraded to Qt 4.6 on my Mac (OS 10.5). When I go to a project directory and run: qmake -project Qt returns this warning (although it doesn't say it's a warning, I assume it is since the .pro file gets created anyway): QFileInfo::absolutePath: Constructed with empty filename I did a completely new install thinking that the "upgrade" wasn't clean for whatever reason, it still does it. Any ideas as to why?

  • Batch file search and replace using wildcards?

    - by user329358
    Batch file search and replace using wildcards I have a html (txt) file I am using as a template or sourcefile to create further html files.  Filename = pg_0001.htm and it contains a line of code thus: pg_0001.jpg I want to parse the pg_0001.htm sourcefile, increment and replace the jpeg string, like this:  "pg_0002.jpg", and then output the edited htm file to a new filename pg_0002.htm I then take each newly created file (pg_0002.htm, pg_0003.htm etc) as the sourcefile and repeat the processing until I have reached my target goal (let's say 100 newly created htm files containing code to display the corresponding jpeg. It must be done this way (fileX.htm containing fileX.jpg) because there is other javascript that uses these incremented filenames as function input. I used to know how to write incrementing batch files many years ago but I'm old & very rusty now.  Can anyone please help me do this?  Many thanks in advance. regards Harry

  • Rails and jQuery - how do you get server-side validation errors to your view after an ajax request

    - by adam
    Ive searched this site but questions are usually regarding doing client-side validations or for different frameworks. I have a tasks list whose items can be edited inline. Upon submitting the inline edit form the item is updated all thanks to jQuery, ajax and rails. But I want to handle bad input from the user. HTML requests redisplay the view and errors are displayed thanks to rails helpers. But how do I insert that information after an ajax call? Heres my update method in my controller def update @task = Task.find(params[:id]) respond_to do |format| if @task.update_attributes(params[:task]) flash[:notice] = 'Task was successfully updated.' format.html { redirect_to(@task) } format.xml { head :ok } format.js else format.html { render :action => "edit" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } #format.js ...hmmm... either go to js.erb file or do stuff inline end end end

  • Implement a WebDAV server in C#?

    - by HaukurHaf
    We've got a CMS system written in .NET C#. This system has editing facilities for templates (essentially HTML files) and various other support files such as CSS and javascript files. These "files" are not really files, but database records and they are edited using plain old textareas within the CMS system. To make editing these "files" easier, on idea was to implement WebDAV support in the CMS system for these files, so users could use some WebDAV client software to connect to the CMS and then open these in VS 2008 for example. Firstly, is this a feasible idea? Secondly, if so ... where do start? Any good articles out there about implementing a WebDAV server in C# to provide access to either physical documents or "pseudo" documents which are in reality just records in a database? Any input appreciated ....
