  • Jquery Cycle Plugin Question - turning off relative links to photos so it goes to a URL

    - by alpdog14
    I am using Jquery Cycle Plugin and it has a side panel that highlights as the photos change and currently when I click on the text the associated photo pulls up then I have to click on the photo to go to the URL but I would like the text itself to link to the URL. I have looked at the fn.cycle.defaults but not sure what to change and I tried a few things but nothing works. If anyone can help me figure this out it would be most helpful. Here are the fn.cycle.defaults: fx: 'fade', // one of: fade, shuffle, zoom, scrollLeft, etc timeout: 4000, // milliseconds between slide transitions (0 to disable auto advance) continuous: 0, // true to start next transition immediately after current one completes speed: 1000, // speed of the transition (any valid fx speed value) speedIn: null, // speed of the 'in' transition speedOut: null, // speed of the 'out' transition next: null, // id of element to use as click trigger for next slide prev: null, // id of element to use as click trigger for previous slide prevNextClick: null, // callback fn for prev/next clicks: function(isNext, zeroBasedSlideIndex, slideElement) pager: null, // id of element to use as pager container pagerClick: null, // callback fn for pager clicks: function(zeroBasedSlideIndex, slideElement) pagerEvent: null, // event which drives the pager navigation pagerAnchorBuilder: null, // callback fn for building anchor links before: null, // transition callback (scope set to element to be shown) after: null, // transition callback (scope set to element that was shown) end: null, // callback invoked when the slideshow terminates (use with autostop or nowrap options) easing: null, // easing method for both in and out transitions easeIn: null, // easing for "in" transition easeOut: null, // easing for "out" transition shuffle: null, // coords for shuffle animation, ex: { top:15, left: 200 } animIn: null, // properties that define how the slide animates in animOut: null, // properties that define how the slide animates out cssBefore: null, // properties that define the initial state of the slide before transitioning in cssAfter: null, // properties that defined the state of the slide after transitioning out fxFn: null, // function used to control the transition height: 'auto', // container height startingSlide: 0, // zero-based index of the first slide to be displayed sync: 1, // true if in/out transitions should occur simultaneously random: 0, // true for random, false for sequence (not applicable to shuffle fx) fit: 0, // force slides to fit container pause: true, // true to enable "pause on hover" autostop: 0, // true to end slideshow after X transitions (where X == slide count) autostopCount: 0, // number of transitions (optionally used with autostop to define X) delay: 0, // additional delay (in ms) for first transition (hint: can be negative) slideExpr: null, // expression for selecting slides (if something other than all children is required) cleartype: 0, // true if clearType corrections should be applied (for IE) nowrap: 0 // true to prevent slideshow from wrapping }; I have tried changing the pageClick and pagerEvent but nothing seems to be working. Please help!!!

  • iPhone Javascript execution time

    - by Rudiger
    Hi guys, In the Apple docs it says that JavaScript execution time is limited to 10 seconds for each top-level entry point. If your script executes for more than 10 seconds, Safari on iPhone OS stops executing the script at a random place I plan to have some Javascript run every 10 seconds or so that will do an AJAX query to the server and rewrite just the section of the page necessary. Will this be possible with these restrictions on the device?

  • Possible to open a text file in a MYSQL stored procedure?

    - by futureelite7
    Is it possible to open and read from a text file in a MYSQL stored procedure? I have a text file with a list of about 50k telephone numbers, and want to write a stored procedure that will open the file, read the 50k lines and store it as rows in a table. I cannot load the file directly using LOAD IN FILE as the table has additional columns that I have to set. Thanks!

  • asp.net with jquery valduation issue

    - by Eyla
    Greetings, I have 2 textboxs, 2 checkboxs and 2 labels. first textbox, checkbox, and label related to each other and the same for the rest. textbox should accept valid phone number based on jquery validation plugin and when the chackbox check the validation rule would change and in both option the error message would disply inside the label. I have no problem to implement that for one text box but when I add second one will have a problem and only the validation will happen for the second one only. please look at my code and advice. <script src="js/jquery-1.4.1.js" type="text/javascript"></script> <script src="js/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript"> var RegularExpression; var USAPhone = /^[01]?[- .]?(\([2-9]\d{2}\)|[2-9]\d{2})[- .]?\d{3}[- .]?\d{4}$/; var InterPhone = /^\d{9,12}$/; var errmsg; function ValidPhoneHome(sender) { if (sender.checked == true) { RegularExpression = InterPhone; errmsg = "Enter 9 to 12 numbers as international number"; } else { RegularExpression = USAPhone; errmsg = "Enter a valid number"; } jQuery.validator.addMethod("phonehome", function(value, element) { return this.optional(element) || RegularExpression.test(value); }, errmsg); } function ValidMobileHome(sender) { if (sender.checked == true) { RegularExpression = InterPhone; errmsg = "Enter 9 to 12 numbers as international number"; } else { RegularExpression = USAPhone; errmsg = "Enter a valid number"; } jQuery.validator.addMethod("mobilephone", function(value, element) { return this.optional(element) || RegularExpression.test(value); }, errmsg); } $(document).ready(function() { ValidPhoneHome("#<%= chkIntphoneHome%>"); ValidMobileHome("#<%= chkIntMobileHome%>"); $("#aspnetForm").validate({ rules: { "<%=txtHomePhone.UniqueID %>": { phonehome: true } } , errorLabelContainer: "#lblHomePhone", rules: { "<%=txtMobileHome.UniqueID %>": { mobilephone: true } } , errorLabelContainer: "#lblMobileHome" }) </script> <asp:CheckBox ID="chkIntphoneHome" runat="server" Text="Internation Code" onclick="ValidPhoneHome(this)" > <asp:TextBox ID="txtHomePhone" runat="server" ></asp:TextBox> <label id="lblHomePhone"></label> <asp:CheckBox ID="chkIntMobileHome" runat="server" Text="Internation Code" onclick="ValidMobileHome(this)" /> <asp:TextBox ID="txtMobileHome" runat="server"></asp:TextBox> <label id="lblMobileHome"></label>

  • understanding P4 describe / diff summary (-ds) option

    - by JavaScriptDude
    Greetings P4 folks, I am trying to understand the P4 describe -ds output. I am assuming that this is the same as the p4 diff -ds output. Here is an example of the "Differences ..." block: ==== //depot/Groups/mygroup/trunk/main/FooBar.java#5 (text) ==== add 7 chunks 13 lines deleted 1 chunks 1 lines changed 16 chunks 92 / 118 lines ~ Now I understand that add and deleted lines are clear but why are there two numbers for the changed lines (92 / 118). Thanks! - JsD

  • Labeling Y axis with PChart

    - by Sortea2
    I am using PChart for PHP to draw graphs, it is working pretty well. I have drawn a graph with intensities (2 = strong, 1 = medium, 0 = low) and I would like to know if is possible to show on the Y axis the description of the data (strong,medium,low) instead of the inappropriate numbers (2,1,0). (I have search a lot without success, theoretically you can only set the X labels according to http://pchart.sourceforge.net/documentation.php?topic=faq.xlabels.) Thanks!

  • PHP: optimum configuration storage ?

    - by Jerome WAGNER
    Hello, My application gets configured via a lot of key/values (let's say 30.000 for instance) I want to find the best deployment method for these configurations, knowing that I want to avoid DEFINEs to allow for runtime re-configuration. I have thought of - pre-compiling them into an array via a php file - pre-compiling them into a tmpfs sqlite database - pre-compiling them into a memcached db what are my options for the best random access time to these configuration (memory is not an issue) ? Thanks Jerome

  • Regex to match words and those with an apostrophe

    - by Beau Martínez
    I'm looking for a regex to only match words, possibly including numbers, and possibly with an apostrophe at the beginning, middle, or end; and ignore everything else. So these would be matched verbatim: 'bout it's persons' But these would be ignored: ' '' However, for words like 'open', open should be matched.

  • sprintf in Delphi?

    - by kroimon
    Hi there! Does anyone know a 100% clone of the C/C++ printf for Delphi? Yes, I know the System.Format function, but it handles things a little different. For example if you want to format 3 to "003" you need "%03d" in C, but "%.3d" in Delphi. I have an application written in Delphi which has to be able to format numbers using C format strings, so do you know a snippet/library for that? Thanks in advance!

  • Java: error handling with try-catch, empty-try-catch, dummy-return

    - by HH
    A searh uses recursively defined function that easily throws exceptions. I have tried 3 ways to handle exeptions: to ignore with an empty-try-catch() add-dummy-return stop err-propagation due to exeption throw a specific except. (this part I don't really understand. If I throw except, can I force it to continue elsewhere, not continuing the old except-thrown-path?) Some exceptions I do not realy care like during execution removed files -exception (NullPointer) but some I really do like unknown things. Possible exceptions: // 1. if a temp-file or some other file removed during execution -> except. // 2. if no permiss. -> except. // 3. ? --> except. The code is Very import for the whole program. I earlier added clittered-checks, try-catches, avoided-empty-try-catches but it really blurred the logic. Some stoned result here would make the code later much easier to maintain. It was annoying to track random exeptions due to some random temp-file removal! How would you handle exceptions for the critical part? Code public class Find { private Stack<File> fs=new Stack<File>(); private Stack<File> ds=new Stack<File>(); public Stack<File> getD(){ return ds;} public Stack<File> getF(){ return fs;} public Find(String path) { // setting this type of special checks due to errs // propagation makes the code clittered if(path==null) { System.out.println("NULL in Find(path)"); System.exit(9); } this.walk(path); } private void walk( String path ) { File root = new File( path ); File[] list = root.listFiles(); //TODO: dangerous with empty try-catch?! try{ for ( File f : list ) { if ( f.isDirectory() ) { walk( f.getAbsolutePath() ); ds.push(f); } else { fs.push(f); } } }catch(Exception e){e.printStackTrace();} } } Code refactored from here.

  • agent-based simulation: performance issue: Python vs NetLogo & Repast

    - by max
    I'm replicating a small piece of Sugarscape agent simulation model in Python 3. I found the performance of my code is ~3 times slower than that of NetLogo. Is it likely the problem with my code, or can it be the inherent limitation of Python? Obviously, this is just a fragment of the code, but that's where Python spends two-thirds of the run-time. I hope if I wrote something really inefficient it might show up in this fragment: UP = (0, -1) RIGHT = (1, 0) DOWN = (0, 1) LEFT = (-1, 0) all_directions = [UP, DOWN, RIGHT, LEFT] # point is just a tuple (x, y) def look_around(self): max_sugar_point = self.point max_sugar = self.world.sugar_map[self.point].level min_range = 0 random.shuffle(self.all_directions) for r in range(1, self.vision+1): for d in self.all_directions: p = ((self.point[0] + r * d[0]) % self.world.surface.length, (self.point[1] + r * d[1]) % self.world.surface.height) if self.world.occupied(p): # checks if p is in a lookup table (dict) continue if self.world.sugar_map[p].level > max_sugar: max_sugar = self.world.sugar_map[p].level max_sugar_point = p if max_sugar_point is not self.point: self.move(max_sugar_point) Roughly equivalent code in NetLogo (this fragment does a bit more than the Python function above): ; -- The SugarScape growth and motion procedures. -- to M ; Motion rule (page 25) locals [ps p v d] set ps (patches at-points neighborhood) with [count turtles-here = 0] if (count ps > 0) [ set v psugar-of max-one-of ps [psugar] ; v is max sugar w/in vision set ps ps with [psugar = v] ; ps is legal sites w/ v sugar set d distance min-one-of ps [distance myself] ; d is min dist from me to ps agents set p random-one-of ps with [distance myself = d] ; p is one of the min dist patches if (psugar >= v and includeMyPatch?) [set p patch-here] setxy pxcor-of p pycor-of p ; jump to p set sugar sugar + psugar-of p ; consume its sugar ask p [setpsugar 0] ; .. setting its sugar to 0 ] set sugar sugar - metabolism ; eat sugar (metabolism) set age age + 1 end On my computer, the Python code takes 15.5 sec to run 1000 steps; on the same laptop, the NetLogo simulation running in Java inside the browser finishes 1000 steps in less than 6 sec. EDIT: Just checked Repast, using Java implementation. And it's also about the same as NetLogo at 5.4 sec. Recent comparisons between Java and Python suggest no advantage to Java, so I guess it's just my code that's to blame? EDIT: I understand MASON is supposed to be even faster than Repast, and yet it still runs Java in the end.

  • Amazon SimpleDB Identity Seed equivalent

    - by Zaff
    Is there an equivalent to an identity Seed in SimpleDB? If the answer is no, how do you handle creating something like a customer number or order number that will prevent the creation duplicate numbers? My experience is mainly from SQL Server in which I would either create a primary key with an identity seed or use transactions in a stored procedure to increment the number. Thanks for your help!

  • FIFO semaphore test

    - by L4N0
    Hello everyone, I have implemented FIFO semaphores but now I need a way to test/prove that they are working properly. A simple test would be to create some threads that try to wait on a semaphore and then print a message with a number and if the numbers are in order it should be FIFO, but this is not good enough to prove it because that order could have occurred by chance. Thus, I need a better way of testing it. If necessary locks or condition variables can be used too. Thanks
