• jquery autocomplete get selected item text

  - by rlee923

  I am wondering how to grab the selected item's text value on jquery autocomplete. I have initialised jquery as following : $(document).ready(function (){ $("input#autocomplete").autocomplete({ source: postcodelist, select: function (event, ui) { AutoCompleteSelectHandler(event, ui) } }); }); And I have created a function function AutoCompleteSelectHandler(event, ui) { }. Inside this function I want to some extra handling to feed data into correct textboxes but I can't figure out how to grab the text value of the selected item. I did google a bit and tried examples but I can't seem to get it working. Any help will be much appreciated. Thanks a lot advance.

• Java inheritance question

  - by user247866

  So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = method-call();` // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void some-method(LIst<A> a) However, when I do: C c = new C(). c. some-method(b) I get an error that some-method is not applicable for the argument List, instead it's expecting to get List. Is there a good way to fix this problem? Many thanks!

• can this code be shortened or improved?

  - by user2816683

  Can this be shortened/improved? I'm trying to make a password checker in python. Could the if's be put into a for loop? And if so, how? pw = input("Enter password to test: ") caps = sum(1 for c in pw if c.isupper()) lower = sum(1 for c in pw if c.islower()) nums = sum(1 for c in pw if c.isnumeric()) scr = ['weak', 'medium', 'strong'] r = [caps, lower, nums] if len(pw) < 6: print("too short") elif len(pw) > 12: print("too long") if caps >= 1: if lower >= 1: if nums >= 1: print(scr[2]) elif nums < 1: print("your password is " + scr[1]) elif lower < 1: print("your password strength is " + scr[0]) elif caps < 1: print("your password strength is " + scr[1]) Thanks for any suggestions :D

• how do I disable options based on the previous selection?

  - by 3r1c

  I have three drop-down menus for each sample shirt; product, colour and grade. Not all products are available in all colours and/or grades. I would like to disable the options that are not available based on the users selection. I've tried using this answer here (using a radio select). Unfortunately, I can't get it to work with an option-selected input. This is what I'm working on - quartus.ca/select-options.html Any guidance would be appreciated.

• JQuery: how to write a selector to find elements with a class ending with a given substring?

  - by curious1

  I use JQuery for my web application. I don't know how to write a selector for this situation. <a class="abc def xyz-delete-confirm efg">text</a> <a class="abc def delete-confirm">text</a> I need to find all links that has a class ending with "-delete-confirm" or has a class called "delete-confirm". I know how to handle the situation of having a class called "delete-confirm". How about the "-delete-confirm situation"? Can I have a single selector covering two situations? Thanks for any input! Regards.

• Is there any sample Java code that does AES encryption exactly like this website?

  - by user1068636

  http://www.hanewin.net/encrypt/aes/aes-test.htm If you go to this website and enter the following: "Key In Hex": 00000000000000000000000000123456 "Plain Text in Hex": 00000000000000000000000000000000 And click on "Encrypt" button you will see the ciphertext in hex is: 3fa9f2a6e4c2b440fb6f676076a8ba04 Is there a Java program out there that I can do this (I.e. Is there an AES library that will input the "Key In Hex" above with the "Plain Text In Hex" above and generate the Ciphertext in Hex above? )? I would appreciate any advice or links to Java sample code that does this.

• $.each - wait for jSON request before proceeding

  - by GaaayLooord

  I have an issue with the below code: the jQuery.each is speeding on without waiting for the JSON request to finish. As a result, the 'thisVariationID' and 'thisOrderID' variables are being reset by the latest iteration of a loop before they can be used in the slower getJSON function. Is there a way to make each iteration of the the .each wait until completion of the getJSON request and callback function before moving on to the next iteration? $.each($('.checkStatus'), function(){ thisVariationID = $(this).attr('data-id'); thisOrderID = $(this).attr('id'); $.getJSON(jsonURL+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&callback=?', function(data){ if (data.response = 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }) })

• private virtual function in derived class

  - by user1706047

  class base { public: virtual void doSomething() = 0; }; class derived : public base { **private:** virtual void doSomething(){cout<<"Derived fn"<<endl;} }; now if i do the following: base *b=new child; b->doSomething(); //it calls the derived class fn even if that is private. Question: 1.its able to call the derived class fn even if that is private.How is it possible? Now if i change the inheritance access specifier from public to protected/private then i get compilation error as "'type cast' : conversion from 'Derived *' to 'base *' exists, but is inaccessible" Notes: I am aware on the concepts of the inheritance access specifiers.So in second case as its derived private/protected, its inaccessible. But here it confuses me for the first question. Any input will be highly appreciated

• sending request to a page

  - by gklots

  hi there. I'm trying to fill-out a form automatically and press a button on that form and wait for a response. How do I go about doing this? To be more particular, I have a a --HUGE-- collection DNA strains which I need to compare to each-other. Luckily, there's a website that does exactly what I need. Basically, I type-in 2 different sequences of DNA and click the "Align Sequences" button and get a result (the calculation of the score is not relevant). Is there a way to make a Java program that will automatically insert the input, "click" the button and read the response from this website? Thanks!

• How do submit an object to a struts2 action using jQuery?

  - by James Drinkard

  I have an object that I'm populating from a selection off a table row that a user selects. I have a jQuery function that captures the click event and a hidden form field populates an id I need. However, I'm not sure as to the proper way to send off that object to a struts2 action? I tried using this: $(function() { $('#tbl tr').click(function() { var id = $(this).closest('tr').find('input:hidden').val(); var page = "<s:url action='update/deleteInfo.action'/>?model.isDelete=true&model.info.id=id"; console.log(page); window.location.href=(page); }); }); The model object has an isDelete boolean variable and the model has a nested info object that has an id variable with getter/setters. However, when I send this across, the model object isn't populated with these entries. Is there a way to do this or a better way than the url tag?

• Does the '#' modifier for cropping images in Paperclip work only for square images?

  - by user3451384

  It is very well documented that you can create square thumbnails with center cropping with Paperclip (4) and Rails (4). I would like to have an image of very specific dimensions (e.g. 200x100) and if input an image of let's say 800x200 it is first resized to 400x100 and then the width (400) is cropped down to 200 pixel from the center (i.e. 100px cut from the right and 100 px cut from the left). I tried with 200x100# and it does not appear to work (i.e. the '#' has no effect). I have found that I could adapt other solutions such as this, but I was wondering if '#' is supposed to work only for cropping to square images, or is a Paperclip bug or I am doing something wrong...

• Associate a URL with a resource within my application

  - by Horace Loeb

  When I visit http://my-application.com/posts/1 in my browser, Rails knows I'm looking for the Post with id = 1. How can I get my application to do this internally? I.e., I'd like a function (call it associate_with_resource) that takes a string containing a URL as its input and outputs the associated resource. For example: >> associate_with_resource('http://my-application.com/posts/1') => #<Post id: 1, ... > (I'd like to be able to use associate_with_resource throughout my application though -- not only in the console)

• Java Web Application

  - by Mark R

  I am interested in creating a simple web application that will take in user input, convert it to an XML file and send the file to a database. Coding wise I feel I am okay, it is just the general setup and what implementation to use I am a bit unsure of. At the moment I have a JSP page containing a form, the user fills out the form and on submit a get method is sent to a servlet, in the servlet doGet() method the servlet is instantiating a java object and passing it the user inputted data. The java object then writes that data to an XML file and sends it to the database via REST. All I would be interested to know is if this the standard/optimal way of creating such a web application. Any and all feedback is appreciated. Thanks

• combining two png files in android

  - by John

  I have two png image files that I would like my android app to combine problematically into one png image file and am wondering if it is possible to do so? if so, what I would like to do is just overlay them on each other to create one file. the idea behind this is that I have a handful of png files, some with a portion of the image on the left with the rest transparent and the others with an image on the right and the rest transparent. and based on user input it will combine the two to make one file to display. (and i cant just display the two images side by side, they need to be one file) is this possible and how so?

• functionality of cin in c++

  - by wyatt

  I'm a bit confused by the results of the following function: int main() { string command; while(1) { cin >> command; if(command == "end") return 0; else cout << "Could you repeat the command?" << endl; } return 0; } First of all - the output line ("could you...") repeats once for each individual word in the input (stored in command). So far as I can see, it should only be possible for it to happen once for each instance of the loop. Also, when the line 'if(command == "end")' is changed to 'if(command == "that's all")' it never triggers. A little testing suggested that all of the whitespace was removed from the command. Could someone explain to me what's going on here? Thanks

• how to generate XML (in String representation) in java

  - by flyingfromchina

  I have defined a java class, but only need to output some of the fields of this class into an XML. The returned type must be a String. I first opted for the easiest way using a StringBuffer. However, when I tried to process the output String represenation, it failed. I think it is mostly likely because there are some characters that are not encoded in the UTF-8 in the input. Could someone tell me what is the best way to handle this? Thanks.

• String path validation

  - by CMAñora

  I have here a string(an input from the user) for a file path. I checked the string so that it will qualify the criteria: check for invalid characters for a file path will not accept absolute path (\Sample\text.txt) I have tried catching the invalid characters in catch clause. It work except for '\'. It will accept 'C:\\Sample\text.txt' which is an invalid file path. The following examples should be invalid paths: :\text.txt :text.txt \:text.txt \text.txt C:\\\text.txt I have been through similar questions posted here but none of them seemed to solve my issue. What would be the best way to do such check?

• PHP DateTime accept multiple formats?

  - by John Smith

  I'm trying to construct a DateTime object with multiple accepted formats. According to the DateTime::createFromFormat docs, the first parameter (format) must be a string. I was wondering if there was a way to createFromFormats. In my case, I want the year for my format to be optional: DateTime::createFromFormat('Y-m-d', $date); DateTime::createFromFormat('m-d', $date); so that a user can input just 'm-d' and the year would be assumed 2013. If I wanted multiple accepted formats, would I have to call createFromFormat each time? Shortest thing for my scenario is: DateTime::createFromFormat('m-d', $date) ?: DateTime::createFromFormat('Y-m-d', $date);

• How can a Perl force its caller to return? [closed]

  - by JS Bangs

  Possible Duplicate: Is it possible for a Perl subroutine to force its caller to return? I want to write a subroutine which causes the caller to return under certain conditions. This is meant to be used as a shortcut for validating input to a function. What I have so far is: sub needs($$) { my ($condition, $message) = @_; if (not $condition) { print "$message\n"; # would like to return from the *parent* here } return $condition; } sub run_find { my $arg = shift @_; needs $arg, "arg required" or return; needs exists $lang{$arg}, "No such language: $arg" or return; # etc. } The advantage of returning from the caller in needs would then be to avoid having to write the repetitive or return inside run_find and similar functions.
