  • How to add ads to the end of RSS on wordpress?

    - by zeina
    I have added a function to functions.php on my theme. function insertAds($content) { $content = $content.' add goes here'; return $content;} add_filter('the_content_feed', 'insertAds'); add_filter('the_excerpt_rss', 'insertAds'); The problem is that I'm having the add displayed under each content, and not at the end of the rss page. How can I fix that?

  • Hook a javascript event to page load

    - by Jagd
    I have an aspx that has the following javascript function being ran during the onload event of the body. <body onload="startClock();"> However, I'm setting the aspx up to use a master page, so the body tag doesn't exist in the aspx anymore. How do I go about registering the startClock function to run when the page is hit and still have it use a masterpage?

  • Can Prototype or JQuery return an HTTP status code on an AJAX request

    - by jotto
    url = "http://example.com" new Ajax.Request(url, { onComplete: function(transport) { alert(transport.status); } }); I'd like that to return a status of 200 if the site is working, or 500 if it is not working, etc.. But that code is returning 0 all the time. Ultimately, I want to have a setinterval function that regularly pings a website for uptime status.

  • How to detect textarea or input type="text" editing?

    - by kavoir.com
    I use this snippet to prevent the user from accidentally navigating away from the editing page: var warning = false; window.onbeforeunload = function() { if (warning) { return ''; } } Now I want to set the variable warning to be true if any of the textarea or input type="text" has been modified, I want to use the onkeyup event such as in: document.getElementById('textarea_id').onkeyup = function() { warning = true; } But it's not working. Don't quite want to use jQuery on this. Any insights?

  • Does variable = null set it for garbage collection

    - by manyxcxi
    Help me settle a dispute with a coworker: Does setting a variable or collection to null in Java aid in garbage collection and reducing memory usage? If I have a long running program and each function may be iteratively called (potentially thousands of times): Does setting all the variables in it to null before returning a value to the parent function help reduce heap size/memory usage?

  • Is there a more modern regexp handler for Open Object Rexx

    - by Brent.Longborough
    The regular expression class (rxregexp.dll) that comes with ooRexx (I'm on 4.0.0) is relatively low on function compared, say, with Python's re module (even at 2.5.2). It appears to have no assertions, no facilities for group extraction, or for substitution. Greedy or lazy matching is a global pattern option, rather than flagged by an additional "?". Basically, a pre-PCRE regular expression engine. Does anyone know if anything with more up-to-date function is available?

  • Passing variables, creating instances, self, The mechanics and usage of classes: need explenation

    - by Baf
    I've been sitting over this the whole day and Im a little tired already so please excuse me being brief. Im new to python. I just rewrrote a working program, into a bunch of functions in a class and everzthings messed up. I dont know if its me but Im very surprised i couldn t find a beginners tutorial on how to handle classes on the web so I have a few questions. First of all, in the init section of the class i have declared a bunch of variables with self.variable=something. Is it correct that i should be able to access/modify these variables in every function of the class by using self.variable in that function? In other words by declaring self.variable i have made these variables, global variables in the scope of the class right? If not how do i handle self. ? Secondly how do i correctly pass arguments to the class? some example code would be cool. thirdly how do i call a function of the class outside of the class scope? some example code would be cool. fouthly how do I create an Instance of the class INITIALCLASS in another class OTHERCLASS, passing variables from OTHERCLASS to INITIALCLASS? some example code would be cool. I Want to call a function from OTHERCLASS with arguments from INITIALCLASS. What Ive done so far is. class OTHERCLASS(): def __init__(self,variable1,variable2,variable3): self.variable1=variable1 self.variable2=variable2 self.variable3=variable3 def someotherfunction(self): something=somecode(using self.variable3) self.variable2.append(something) print self.variable2 def somemorefunctions(self): self.variable2.append(variable1) class INITIALCLASS(): def __init__(self): self.variable1=value1 self.variable2=[] self.variable3='' self.DoIt=OTHERCLASS(variable1,variable2,variable3) def somefunction(self): variable3=Somecode #tried this self.DoIt.someotherfunctions() #and this DoIt.someotherfunctions() I clearly havent understood how to pass variables to classes or how to handle self, when to use it and when not, I probably also havent understood how to properly create an isntance of a class. In general i havent udnerstood the mechanics of classes So please help me and explain it to me like i have no Idea( which i dont it seems). Or point me to a thorough video, or readable tutorial. All i find on the web is super simple examples, that didnt help me much. Or just very short definitions of classes and class methods instances etc. I can send you my original code if you guys want, but its quite long. Thanks for the Help Much appreciated!

  • deep or shallow copying?

    - by Dervin Thunk
    Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?

  • PHP problem with getimagesize()

    - by RobHardgood
    I'm using the getimagesize() function in PHP and it keeps returning an error: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory I'm not doing anything strange with it. The only problem I can imagine is that the path URL is another PHP script that returns a page with an image header, and there is an ampersand in that URL. Here is my code: $location = "image.php?name=username&pic=picture"; $size = getimagesize($location);

  • Javascript: Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • How to get points that intersect the treadline?

    - by chutsu
    Basically I did the Cavendish experiment, and I have a damped sinusoidal wave plotted on Excel. With Position (mm) against Time (s). My problem is that I have added a tread line through the wave function, and wish to calculate the points of which the wave function intersects the tread line. From this I will then be able to calculate the time period. At the moment I'm just having difficulty getting the intersects.. Thanks

  • How to pass non-fatal warnings from a library

    - by wRAR
    A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

  • How do I change the curosr during a jQuery synchronous browser blocking POST?

    - by Tommy
    $.ajax({ url: "/cgi-bin/stats.exe", method: "post", async: false, data: { refresh: "a41" } }); Using ajax post synchronously - "async: false". While it blocks the browser during the active request, what is the most efficient way to change the cursor to the hourglass or display a wait .gif? Perhaps set the cursor as it enters this function then change it back in the success or complete function? Any advice is appreciated. Thank You.

  • JPA CascadeType.ALL does not delete orphans.

    - by Paul Whelan
    I am having trouble deleting orphan nodes using JPA with the following mapping @OneToMany (cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "owner") private List<Bikes> bikes; I am having the issue of the orphaned roles hanging around the database. I can use the @org.hibernate.annotations.Cascade Hibernate specific tag but obviously I don't want to tie my solution into a hibernate implementation. Any pointers greatly appreciated.

  • How to pass an integer to create new variable name?

    - by Joe
    I have 50 svg animations named animation0, animation1, animation2 etc. and I want to load them when the integer 0 to 49 is passed to this function: function loadAnimation(value){ var whichswiffy = "animation" + value; var stage = new swiffy.Stage(document.getElementById('swiffycontainer'), whichswiffy); stage.start(); } It doesn't work at the moment, maybe it's passing 'whichswiffy' rather than 'animation10'? Any ideas?
