  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • null pointer exception comparing two strings in java.

    - by David
    I got this error message and I'm not quite sure whats wrong: Exception in thread "main" java.lang.NullPointerException at Risk.runTeams(Risk.java:384) at Risk.blobRunner(Risk.java:220) at Risk.genRunner(Risk.java:207) at Risk.main(Risk.java:176) Here is the relevant bits of code (i will draw attention to the line numbers within the error message via comments in the code as well as inputs i put into the program while its running where relevant) public class Risk { ... public static void main (String[]arg) { String CPUcolor = CPUcolor () ; genRunner (CPUcolor) ; //line 176 ... } ... public static void genRunner (String CPUcolor) // when this method runs i select 0 and run blob since its my only option. Theres nothing wrong with this method so long as i know, this is only significant because it takes me to blob runner and because another one of our relelvent line numbers apears. { String[] strats = new String[1] ; strats[0] = "0 - Blob" ; int s = chooseStrat (strats) ; if (s == 0) blobRunner (CPUcolor) ; // this is line 207 } ... public static void blobRunner (String CPUcolor) { System.out.println ("blob Runner") ; int turn = 0 ; boolean gameOver = false ; Dice other = new Dice ("other") ; Dice a1 = new Dice ("a1") ; Dice a2 = new Dice ("a2") ; Dice a3 = new Dice ("a3") ; Dice d1 = new Dice ("d1") ; Dice d2 = new Dice ("d2") ; space (5) ; Territory[] board = makeBoard() ; IdiceRoll (other) ; String[] colors = runTeams(CPUcolor) ; //this is line 220 Card[] deck = Card.createDeck () ; System.out.println (StratUtil.canTurnIn (deck)) ; while (gameOver == false) { idler (deck) ; board = assignTerri (board, colors) ; checkBoard (board, colors) ; } } ... public static String[] runTeams (String CPUcolor) { boolean z = false ; String[] a = new String[6] ; while (z == false) { a = assignTeams () ; printOrder (a) ; boolean CPU = false ; for (int i = 0; i<a.length; i++) { if (a[i].equals(CPUcolor)) CPU = true ; //this is line 384 } if (CPU==false) { System.out.println ("ERROR YOU NEED TO INCLUDE THE COLOR OF THE CPU IN THE TURN ORDER") ; runTeams (CPUcolor) ; } System.out.println ("is this turn order correct? (Y/N)") ; String s = getIns () ; while (!((s.equals ("y")) || (s.equals ("Y")) || (s.equals ("n")) || (s.equals ("N")))) { System.out.println ("try again") ; s = getIns () ; } if (s.equals ("y") || s.equals ("Y") ) z = true ; } return a ; } ... } // This } closes the class The reason i don't think i should be getting a Null:pointerException is because in this line: a[i].equals(CPUcolor) a at index i holds a string and CPUcolor is a string. Both at this point definatly have a value neither is null. Can anyone please tell me whats going wrong?

  • Moved X-cart site to Sub Directory - Need Help setting up Redirects

    - by Rich G
    I recently moved an x-cart site from a root directory to a sub directory, and also built a new Wordpress site under the root directory. The problem I am having is that I am trying to figure out a redorect combo that will show the search engines that the product pages are now under the sub directory (/store) but do not want the search engines to exclude the brand new site under the Root directory. I was thinking that if I could just have redirect any .html file (all of the product pages link to .html pages) that it would redirect to the same page just under the sub directory. The reason I cannot do everything one by one is because there are about 50k+ products that would need be changed. Any information and help would be greatly appreciated! Thank you in advanced!

  • How to find links and modify an Html using BeautifulSoup in Python

    - by systempuntoout
    Starting from an Html input like this: <p> <a href="http://www.foo.com">this if foo</a> <a href="http://www.bar.com">this if bar</a> </p> using BeautifulSoup, i would like to change this Html in: <p> <a href="http://www.foo.com">this if foo[1]</a> <a href="http://www.bar.com">this if bar[2]</a> </p> saving parsed links in a dictionary with a result like this: links_dict = {"1":"http://www.foo.com","2":"http://www.bar.com"} Is it possible to do this using BeautifulSoup? Any valid alternative?

  • Printing UTF-16 strings in JSP is outputted as HTML encoding (&#xxxx)

    - by Ori Osherov
    Hello, When I try to print a UTF-16 string in JSP, specifically Hebrew, it ends up showing up as HTML encoding (&#xxxx). This problem occurs because I print an array of variables into the web page and then parse them. The variables are all UTF-16 strings, but once the servlet prints the variables, it becomes translated to HTML encoding. Is there any way to get rid of the encoding? Thanks in advance Edit for a bit more background: The JSP that I'm printing is not the entirety of the page. It's used in a manner I don't quite understand by a server app which prints the JSPs output into its built in page. As a result, I can't, for instance, use a tag because the will have already been placed somewhere else. This isn't a frame or anything like that. It's just redirected output.

  • jquery dialog is clearing my form fields and I need to return a value from a jquery dialog

    - by Seth
    1.) I have a jQuery dialog that is opened whenever a particular textbox is focused. The dialog's contents are loaded from ajax and the unique ID of the textbox that was focused is passed in the ajax call (like this): $('[name=start_airport[]],[name=finish_airport[]]').click(function(){   var id = $(this).attr('id');   if($('#use_advanced_airport_selector').attr('checked')) {     $('#advanced_airport_selector').dialog({       open : function() {         $(this).load('/flight-booker/advanced-airport-selector.php?callerID='+id);       }     });     $('#advanced_airport_selector').dialog('open');   } }); (where advanced_airport_selector is an empty div) THAT PART WORKS FINE. However, when I make my ajax call within my dialog, all my form values are reset! No matter what I do, when that dialog opens, all form values are reset (not just the value of the textbox that was focused). I simply don't understand what would cause this behavior! But that's only issue #1. 2.) I need to be able to return a value from that dialog box. I am passing the ID in the ajax query so that I can use a jquery selector to update the caller's value after certain actions are performed within the dialog box. However, I can't actually access that textbox because of DOM_ERRORS that I've never come across. It doesn't make any sense! There's way to much code to post, and it's really hard to explain, so sorry if I'm unclear as to what I'm asking.

  • Whats wrong with this method?

    - by David
    Here's the method: public static String CPUcolor () { System.out.println ("What color am I?") ; String s = getIns() ; System.out.println ("are you sure I'm "+s+"? (Y/N)") ; String a = getIns() ; while (!((a.equals ("y")) || (a.equals ("Y")) || (a.equals ("n")) || (a.equals ("N")))) { System.out.println ("try again") ; a = getIns () ; } if (a.equals ("n") || a.equals("N")) {CPUcolor() ;} System.out.println ("I am "+s) ; return s ; } here is a possible output of this method (y's and n's are user inputs): What color am I? red are you sure I'm red? (Y/N) N What color am I? blue are you sure I'm blue? (Y/N) N What color am I? Yellow are you sure I'm Yellow? (Y/N) y I am Yellow I am blue I am red Why is it that the line's "I am blue" and "I am Blue" printed? Why are they printed in reverse order with red, the first entered, printed last?

  • Visual Studio Add-in Exec running Automatically

    - by NewProgrammer
    Hey guys, I have a dilemma that I am uncertain about, as I not sure if it's is exactly possible for a Visual Studio Add-in to run its code automatically. I need an add-in that can run passively, like a logger for Visual Studios. However, the Exec method that I know so far can only execute commandbar functionality, but I need the code to execute when the user right-clicks, or select a line of text. I was able to make an automatic logger if i put my code in the "querystatus", but that would be considered bad programming, and it does not log when I simply select a piece of text. Does anyone know how to make a passive or automatic running code in Visual Studios?

  • Using CouchDB to serve HTML.

    - by alxross
    I'm trying to use CouchDB with HTML/standalone REST architecture. That is, no other app server other than CouchDB and ajax style javascript calling CouchDB. It looks like cross scripting is a problem. I was using Cloudkit/Tokyo Cabinet before and it seems like the needed callback function was screwing it up in the URL. Now I'm trying CouchDB and getting the same problem. Here are my questions: 1) Are these problems because the REST/JSON store like CouchDB or CloudKit is running on a different port from my web page? They're both run locally and called from "localhost". 2) Should I let CouchDB host my page and serve the HTML? 3) How do I do this? The documentation didnt seem so clear... Thanks, Alex

  • BeautifulSoup Parser Confusion - HTML

    - by lyngbym
    I'm trying to scrape some content off another site and I'm not sure why BeautifulSoup is producing this output. It is only finding a blank space inside the match, but the real HTML contains a large amount of markup. I apologize if this is something stupid on my part. I'm new to python. Here's my code: import sys import os import mechanize import re from BeautifulSoup import BeautifulSoup def scrape_trails(BASE_URL, data): #Get the trail names soup = BeautifulSoup(data) sitesDiv = soup.findAll("div", attrs={"id" : "sitesDiv"}) print sitesDiv def main(): BASE_URL = "http://www.dnr.state.mn.us/skiing/skipass/list.html" br = mechanize.Browser() data = br.open(BASE_URL).get_data() links = scrape_trails(BASE_URL, data) if __name__ == '__main__': main() If you follow that URL you can see the sitesDiv contains a lot of markup. I'm not sure if I'm doing something wrong or if this is just malformed markup that the script can't handle. Thanks!

  • Finding the right name for an include that is to be executed before HTML output

    - by Pekka
    I am defining naming conventions for a simple plugin framework. For example: index.php - the main plugin file info.php - returns an array with plugin information install.php - self-explanatory can you think of an elegant, short-hand name for a PHP file that contains the code that is to be executed before any HTML is output? Do any examples from other frameworks come to your mind? What I have been thinking of: head.php - misleading, could be mixed up with HTML <head> before_output.php - clumsy, too long init.php - not exactly correct start.php - current favourite
