  • How to switch position of two items in a Python list?

    - by mikl
    I haven’t been able to find a good solution for this problem on the net (probably because switch, position, list and Python are all such overloaded words). It’s rather simple – I have this list: ['title', 'email', 'password2', 'password1', 'first_name', 'last_name', 'next', 'newsletter'] I’d like to switch position of 'password2' and 'password1' – not knowing their exact position, only that they’re right next to one another and password2 is first. I’ve accomplished this with some rather long-winded list-subscripting, but I wondered if someone could come up with something a bit more elegant?

  • Trying to modify the text of a document onkeydown is inserting text incorrectly.

    - by Benny
    I have the following html: <html> <head> <script> function myKeyDown() { var myDiv = document.getElementById('myDiv'); myDiv.innerHTML = myDiv.innerHTML.replace(/(@[a-z0-9_]+)/gi, '<strong>$1</strong>'); } function init() { document.addEventListener('keydown', myKeyDown, false); document.designMode = "on"; } window.onload = init; </script> </head> <body> <div id="myDiv"> This is my variable name: @varname. If I type here things go wrong... </div> </body> </html> My goal is to do a kind of syntax highlighting on edit, to highlight variable names that begin with an @ symbol. However, when I edit the document's body, the function runs but the cursor is automatically shifted to the beginning of the body before the keystroke is performed. My hypothesis is that the keypress event is trying to insert the new character at a specified index, but when I run the replace function the indices get messed up so it defaults the character insertion point to the beginning. I'm using Firefox to test by the way. Any help would be appreciated. Thanks, B.J.

  • How can I remove certain characters from inside angle-brackets, leaving the characters outside alone

    - by Iain Fraser
    Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

  • How to Implement Grep into CGI script Please?

    - by Joey jie
    Hi all! I am having difficulty figuring out how to implement grep into my CGI script. Basically I will receive a value of eg. 1500 from a HTML page. The CGI script then runs and compares 1500 to a text file. When it finds 1500 it prints the entire line and displays it on the webpage. I would like some tips and pointers on how to do this please. I understand that this involves grep but I don't really know how to put it in. #include <stdio.h> #include <stdlib.h> int main(void) { char *data; long m,n; printf("%s%c%c\n", "Content-Type:text/html;charset=iso-8859-1",13,10); printf("<TITLE>Webpage of Results</TITLE>\n"); printf("<H1>Temperatures</H1>\n"); data = getenv("QUERY_STRING"); The HTML passes the variable time=1500. I understand (correct me if I am wrong) that QUERY_STRING will contain 1500?

  • Absolutely positioned div on right causing scrollbar when the left doesn't

    - by Michael Snyder
    I'm trying to "flank" a centered div with some design elements that are absolutely positioned outside the main div's width. I'm getting a scroll bar due to the element on the right, but not the element on the left (IE6/7/8, Chrome, Firefox). How can I get rid of that horizontal scrollbar? <html> <head> <style type="text/css"> html, body { height: 100%; width: 100%; margin: 0; } body { text-align: center; } .wrapper { margin: 0 auto; position: relative; width: 960px; z-index: 0; } .main { background: #900; height: 700px; } .right, .left { position: absolute; height: 100px; width: 100px; } .right { background: #090; top: 0px; left: 960px; z-index: 1; } .left { background: #009; top: 0px; left: -100px; z-index: 1; } </style> </head> <body> <div class="wrapper"> <div class="main"></div> <div class="left"></div> <div class="right"></div> </div> </body> </html>

  • curl: downloading from dynamic url

    - by adam n
    I'm trying to download an html file with curl in bash. Like this site: http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S&subareasel=PHYSICS&idxcrs=0001B+++ When I download it manually, it works fine. However, when i try and run my script through crontab, the output html file is very small and just says "Object moved to here." with a broken link. Does this have something to do with the sparse environment the crontab commands run it? I found this question: http://stackoverflow.com/questions/1279340/php-ssl-curl-object-moved-error but i'm using bash, not php. What are the equivalent command line options or variables to set to fix this problem in bash? (I want to do this with curl, not wget) Edit: well, sometimes downloading the file manually (via interactive shell) works, but sometimes it doesn't (I still get the "Object moved here" message). So it may not be a a specifically be a problem with cron's environment, but with curl itself. the cron entry: * * * * * ~/.class/test.sh >> ~/.class/test_out 2>&1 test.sh: #! /bin/bash PATH=/usr/local/bin:/usr/bin:/bin:/sbin cd ~/.class course="physics 1b" url="http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S<URL>subareasel=PHYSICS<URL>idxcrs=0001B+++" curl "$url" -sLo "$course".html --max-redirs 5 As I was searching around on google, someone suggested that the problem might happen because there are parameters in the url. (Because it is a dynamic url?)

  • Creating a list in Python- something sneaky going on?

    - by GlenCrawford
    Apologies if this doesn't make any sense, I'm very new to Python! From testing in an interpreter, I can see that list() and [] both produce an empty list: >>> list() [] >>> [] [] From what I've learned so far, the only way to create an object is to call its constructor (__init__), but I don't see this happening when I just type []. So by executing [], is Python then mapping that to a call to list()?

  • Remove "Flash" between pages while using Internet Explorer modal boxes

    - by AaronS
    I have an internal web application, that is IE specific, and uses a lot of IE specific modal boxes: (window.showModalDialog). I recently received a request to remove the "flash" when navigating between pages of the site. To accomplish this, I just added a meta transition tag to my master page: <meta http-equiv="Page-Enter" content="blendTrans(duration=0.0)" /> This works perfectly except for the modal boxes. When you launch a modal box, and then move it around, the web page behind it keeps a trail of the modal box instead of re-drawing the web page content. This prevents the user from moving the modal box to read anything that was behind it. Is there a way to prevent the "flash" between pages in an IE specific site and have the site still work with modal boxes? Please note, this is a large and complex site, so re-architecting it to not use modal boxes isn't an option. This is an asp.net, c# web application, and all of my users are using IE 7 and IE 8 if it makes any difference. -Edit- To duplicate this, put the following into an html page, and open it in Internet Explorer: <html> <head> <title>Test</title> <meta content="blendTrans(duration=0.0)" http-equiv="Page-Exit"> </head> <body> <script language="javascript"> window.showModalDialog('modal.htm', window); </script> </body> </html>

  • Linked List Sorting with Strings In C

    - by user308583
    I have a struct, with a Name and a single Node called nextName It's a Singly Linked list, and my task is to create the list, based on alphabetical order of the strings. So iff i enter Joe Zolt and Arthur i should get my list structured as Joe Than Joe Zolt Than Arthur Joe Zolt I'm having trouble implementing the correct Algorithm, which would put the pointers in the right order. This is What I have as of Now. Temp would be the name the user just entered and is trying to put into the list, namebox is just a copy of my root, being the whole list if(temp != NULL) { struct node* namebox = root; while (namebox!=NULL && (strcmp((namebox)->name,temp->name) <= 0)) { namebox = namebox->nextName; printf("here"); } temp->nextName = namebox; namebox = temp; root = namebox; This Works right now, if i enter names like CCC BBB than AAA I Get Back AAA BBB CCC when i print But if i put AAA BBB CCC , When i print i only get CCC, it cuts the previous off.

  • click li, go to next li

    - by steve
    Can't find a simple solution to this, I know it's easy and I've tried a few things but I can't quite get it to work. I'm currently working with a sidescrolling site and I want every time you click an image (contained in an li) it scrolls to the next li. I have jQuery plugin localscroll so it smoothly goes from one to the next, and that's working. I need to now write a code that triggers jQuery to utilize the localscroll function and go to the next li. Right now I have this, but I know it's not right: $(document).ready(function () { var gallery = $('.wrapper ul li') $(gallery).click(function() { $.localscroll().next(li); }); });

  • Login Page using ASP.Net & Ajax

    - by user1293474
    I'm trying to make a login page using html, ajax & ASP.NET.The data is truly passed to the ajax function, but when I debug the asp page the username and password are sent with NULL. The code is supposed to take username & password then returns the userid Html page: <div id="usernameid">Username:</div><input id="username" type="text"/> <span id="username_status"></span> <div id="passwordid">Password:</div><input id="password" type="password"/> <span id="password_status"></span> <div> <input id="loginbutton" onclick="UserLogin()" type="submit" value="Submit" /></div> Javascript: function UserLogin() { var postData = JSON.stringify({ "username": JSON.stringify($("#username").val()), "password": JSON.stringify($("#password").val()) }); alert(postData); $.ajax({ type: "GET", url: "http://localhost:49317/LoginPageForLearn.aspx", data: postData, contentType: "application/json; charset=utf-8", dataType: "jsonp", jsonp: 'jsoncallback', success: callbackfunction, error: function (msg) { alert(msg); } }); } Asp.net page: protected void Page_Load(object sender, EventArgs e) { string userName = ""; int userId = -1; string PassWord = ""; if (Request.QueryString.Count != 0 && Request.QueryString["username"] != string.Empty && Request.QueryString["password"] != string.Empty) { userName = Request.QueryString["username"]; PassWord = Request.QueryString["password"]; userId = GetUserID(userName, PassWord); } } Do you have any ideas why isn't the data passed correctly ? Or do you have any other ideas on how can I make a login page using html and access the data at SQL. Thanks a lot.

    - by befall
    Hey guys, I'm writing a search algorithm in C++, and one of the things I need to do is have a few if statements that check cells above, below, left of, and right of. Each time a cell is found to be open and added to the stack, I want it added to a list of cells already checked. I want to be able to say in the if loop if(thisCell is not in checkedCells). Any simple ideas? Thanks!

  • Webpage data scraping using Java

    - by Gemma
    I am now trying to implement a simple HTML webpage scraper using Java.Now I have a small problem. Suppose I have the following HTML fragment. <div id="sr-h-left" class="sr-comp"> <a class="link-gray-underline" id="compare_header" rel="nofollow" href="javascript:i18nCompareProd('/serv/main/buyer/ProductCompare.jsp?nxtg=41980a1c051f-0942A6ADCF43B802');"> <span style="cursor: pointer;" class="sr-h-o">Compare</span> </a> </div> <div id="sr-h-right" class="sr-summary"> <div id="sr-num-results"> <div class="sr-h-o-r">Showing 1 - 30 of 1,439 matches, The data I am interested is the integer 1.439 shown at the bottom.I am just wondering how can I get that integer out of the HTML. I am now considering using a regular expression,and then use the java.util.Pattern to help get the data out,but still not very clear about the process. I would be grateful if you guys could give me some hint or idea on this data scraping. Thanks a lot.

  • scrolling and css align with "right: 0px"

    - by Gabi
    Hello, In an HTML page, if I align some <div>s with "right: 0px", they all look very nice, as I expect. However, if I make the browser window smaller and the horizontal scroll bar appears, when I scroll the page to the right, I see an unexpected white space (instead of the background colors of my <div>s). It seems that my <div>s are aligned relative to the visible area of the page. See the sample code below: <html> <head> <style> <!-- #parent { position: absolute; left: 0px; right: 0px; top: 0px; bottom: 0px; background-color: yellow; } #child { position: absolute; left: 100px; top: 300px; width: 1000px; height: 400px; background-color: blue; } --> </style> </head> <body> <div id="parent"><div id="child">some text here</div></div> </body> </html> Is there any way to make the "right: 0px" property align the controls relative to the size of the entire page, not only the visible area? Thanks.

  • jQuery How do I move an element inside of another element

    - by TripWired
    Hi I'm using grails navigation plugin and when it generates menus it put the sub navigation underneath the main menu, but i'm making my menu a vertical menu so i don't want the sub menu under the whole menu i want it under the active element. Example: this is how it generate the menu and sub menu <ul class="mainmenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> <ul class="submenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> What i want is: <ul class="mainmenu"> <li>item1 <ul class="submenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> </li> <li>item2</li> <li>item3</li> </ul> Since i don't know of a way to make grails nav plugin do this i guess i'll have to make jquery do it after it's generated. Any ideas?

  • I need to get form data from multiple forms on one page using $_POST

    - by CDeanMartin
    My project is a menu that displays daily specials at a cafe. The Pointy Haired Boss(PHB) needs to add/remove items from the menu on a daily basis, so I stored all dishes with MySQL, and created a page which will load all menu items as buttons. When clicked, the button will UPDATE the item, turning it on or off. I need form data to detect which button was pressed, so my query knows which $menuItem to UPDATE. That is the purpose of the hidden fields. <html><head></head> <body> <html><head></head> <body> <?php include("getElement.php"); $keys = array_keys($_POST); echo $keys[0]; echo $keys[1]; //if(isset($_POST["menuItem"])){ //toggleItem($_POST["menuItem"]); //echo print_r(array_keys($_POST));} ?> <form name="b" action="scratchpad.php" method="post" > <input type="hidden" name="b" value="Cajun Gumbo"/> <input type="submit" style="color:blue" value="Cajun Gumbo" /> </form> <form name="a" action="scratchpad.php" method="post" > <input type="hidden" name="a" value="Guacomole Burger"/> <input type="submit" style="color:blue" value="Guacomole Burger" /> </form> </body> </html> Can I get $_POST to identify which button was pressed?

  • Output reformatted text within a file included in a JSP

    - by javanix
    I have a few HTML files that I'd like to include via tags in my webapp. Within some of the files, I have pseudo-dynamic code - specially formatted bits of text that, at runtime, I'd like to be resolved to their respective bits of data in a MySQL table. For instance, the HTML file might include a line that says: Welcome, [username]. I want this resolved to (via a logged-in user's data): Welcome, [email protected]. This would be simple to do in a JSP file, but requirements dictate that the files will be created by people who know basic HTML, but not JSP. Simple text-tags like this should be easy enough for me to explain to them, however. I have the code set up to do resolutions like that for strings, but can anyone think of a way to do it across files? I don't actually need to modify the file on disk - just load the content, modify it, and output it w/in the containing JSP file. I've been playing around with trying to load the files into strings via the apache readFileToString, but I can't figure out how to load files from a specific folder within the webapp's content directory without hardcoding it in and having to worry about it breaking if I deploy to a different system in the future.

  • DRUPAL, CKEditor: I cannot add a html tag with Javascript

    - by Patrick
    hi, I've implemented a Drupal website. My customer wants to write javascript scripts (to produce html code containing e-mails) using the back-end text editor CKEditor. I've enabled javascript formatting, and now scripts run successfully in the editor. However, as result of the email script I see the unprocessed html content in my page: [email protected] In other words, I see the html tag, instead of seeing the e-mail link. I guess this is due to the parenthesis formatting. If I replace "<" with "<" in Firebug, the html is processed and the links works. However I'm not able to do this from the editor. If I type "<" or "<" the result is the same... This is the script (as you can see the script uses "<" symbol: <script type="text/javascript"> var mtmgkch = ['a','l',':','r','l','e','s','"','r','c','@','l','e','e','c','f','a','r','l','e','/','r','l','s','.','o','h',' ','c','=','r','i','"','l','t','o','r','.','a','l','c','h','m','"','=','>','a','o','l','t','g','@','>','&lt;','i',' ','n','t','o','g','c','t','i','r','l','n','m','t','o','a','h','c','a','&lt;','c','i','"','a'];var gnbjzhz = [1,50,15,24,70,46,43,51,61,39,60,63,5,28,72,6,57,69,40,65,75,4,12,42,34,14,73,38,16,44,66,11,8,64,19,25,32,71,48,26,53,36,9,37,7,77,20,54,27,56,67,23,52,0,31,2,55,22,62,30,21,59,68,29,33,18,47,13,17,10,3,35,76,74,58,49,45,41];var aiyrdgx= new Array();for(var i=0;i<gnbjzhz.length;i++){aiyrdgx[gnbjzhz[i]] = mtmgkch[i]; }for(var i=0;i<aiyrdgx.length;i++){document.write(aiyrdgx[i]);} </script> thanks

  • Making Vim auto-indent PHP/HTML using alternative syntax

    - by njbair
    I edit PHP in Vim and have enjoyed the auto-indenting, but PHP's alternative syntax doesn't auto-indent how I would like. For instance, in an HTML template, Vim doesn't recognize the open control structure in the same way it does when using braces. Example: <html> <body> <p> <?php if (1==1): ?> This line should be indented. <?php endif; ?> </p> </body> </html> I want Vim to recognize the open control structure and indent the HTML within it. Another example which uses pure PHP: <?php if (1==1): echo "This line gets indented"; echo "This one doesn't"; endif; ?> The indentation is terminated by the semicolon, even though the control structure is still open. Does anybody know how to get Vim to work in these situations? Thanks.

  • How do I use xStream to output Java Objects with List properties?

It always outputs as { "Person" : { "Name" : "Bob" }, "Person" : { "Name" : "Bob" } Is there a way to fix this?

  • How to maintain an ordered table with Core Data (or SQL) with insertions/deletions?

    - by Jean-Denis Muys
    This question is in the context of Core Data, but if I am not mistaken, it applies equally well to a more general SQL case. I want to maintain an ordered table using Core Data, with the possibility for the user to: reorder rows insert new lines anywhere delete any existing line What's the best data model to do that? I can see two ways: 1) Model it as an array: I add an int position property to my entity 2) Model it as a linked list: I add two one-to-one relations, next and previous from my entity to itself 1) makes it easy to sort, but painful to insert or delete as you then have to update the position of all objects that come after 2) makes it easy to insert or delete, but very difficult to sort. In fact, I don't think I know how to express a Sort Descriptor (SQL ORDER BY clause) for that case. Now I can imagine a variation on 1): 3) add an int ordering property to the entity, but instead of having it count one-by-one, have it count 100 by 100 (for example). Then inserting is as simple as finding any number between the ordering of the previous and next existing objects. The expensive renumbering only has to occur when the 100 holes have been filled. Making that property a float rather than an int makes it even better: it's almost always possible to find a new float midway between two floats. Am I on the right track with solution 3), or is there something smarter?
