  • Codeigniter .htaccess not working in subdirectory

    - by xzdead
    I have this codeingniter project structure webRoot | |/application | | | |/controllers | | | |/admin | |/public | | | |/admin | | | | | |/css | | |/img | |/css | |/img And this is my .htacess file, located in /public. I use this in every local project running xampp: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> <IfModule !mod_rewrite.c> # If we don't have mod_rewrite installed, all 404's # can be sent to index.php, and everything works as normal. # Submitted by: ElliotHaughin ErrorDocument 404 /index.php </IfModule> It works fine in localhost, but doesn't work in a dreamhost server. I always get "no input file specified". So after searching the web and trying lots of combinations, the best I got is this .htaccess file: Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] With this one, if I go to http://development.mydomain.com - I see the codeigniter welcome page But if I go to: http://development.mydomain.com/admin - I see the directory listing of /public/admin and doesn't execute the controller in /application/controllers/admin Again, if I go to: http://development.mydomain.com/admin/admin - I see the private area, it executes the controller and goes to the default controller defined in routes, "dashboard" This works fine too: http://development.mydomain.com/admin/dashboard I have set in my config file: $config['index_page'] = ''; $config['base_url'] = ''; $config['uri_protocol'] = 'AUTO'; I think that whatever is wrong in my .htaccess is causing other path issues I have with my project. Any help would be great. Thanks to all in advance EDIT: I removed this line: RewriteCond %{REQUEST_FILENAME} !-d because admin directory exists, that's why I see the public directory listing. But now I see the codeigniter welcome page when I go to http://development.mydomain.com/admin So now my .htaccess file looks like: Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] #RewriteRule ^(.*)$ /index.php?/$1 [L] I also tried with the commented RewriteRule but I get the same result.

  • C++ read registry string value in char*

    - by Sunny
    I'm reading a registry value like this: char mydata[2048]; DWORD dataLength = sizeof(mydata); DWORD dwType = REG_SZ; ..... open key, etc ReqQueryValueEx(hKey, keyName, 0, &dwType, (BYTE*)mydata, &dataLength); My problem is, that after this, mydata content looks like: [63, 00, 3A, 00, 5C, 00...], i.e. this looks like a unicode?!?!. I need to convert this somehow to be a normal char array, without these [00], as they fail a simple logging function I have. I.e. if I call like this: WriteMessage(mydata), it outputs only "c", which is the first char in the registry. I have calls to this logging function all over the place, so I'd better of not modify it, but somehow "fix" the registry value. Here is the log function: void Logger::WriteMessage(const char *msg) { time_t now = time(0); struct tm* tm = localtime(&now); std::ofstream logFile; logFile.open(filename, std::ios::out | std::ios::app); if ( logFile.is_open() ) { logFile << tm->tm_mon << '/' << tm->tm_mday << '/' << tm->tm_year << ' '; logFile << tm->tm_hour << ':' << tm->tm_min << ':' << tm->tm_sec << "> "; logFile << msg << "\n"; logFile.close(); } }

  • How would I go about letting a user add and associate a comma separated list of categories while add

    - by Throlkim
    I've been struggling for quite a while to get this feature working: I want my user to be able to select categories when uploading a photograph, but additionally be able to specify a comma-separated list of categories to create/find and associate with the photograph. I've had this working by using an attr_accessor :new_categories on the photographs model, but having that there without the column existing breaks both Paperclip and Exifr. Obviously, image upload and EXIF data retrieval are pretty important for a photography website, but not being able to add categories while uploading a photograph is a pain in the arse. Methods I've tried so far: Using attr_accessor to add a field for new_categories. Breaks gems. Using an Ajax sub-form to add categories. Formtastic can't handle it. Adding a column for new_categories to the photograph model. It works, but it's horrific. I haven't tried using a nested form, but I'd need to intercept it and stop it from processing it as normal. Here's an example of what I'm trying to accomplish: http://imgur.com/rD0PC.png And the function I use to associate the categories: def process_new_categories unless self.new_categories.nil? for title in self.new_categories.split(",") self.categories << Category.find_or_create_by_title(title.strip.capitalize) end end end Has anyone got any ideas as to how to do this?

  • Documentation style: how do you differentiate variable names from the rest of the text within a comm

    - by Alix
    Hi, This is a quite superfluous and uninteresting question, I'm afraid, but I always wonder about this. When you're commenting code with inline comments (as opposed to comments that will appear in the generated documentation) and the name of a variable appears in the comment, how do you differentiate it from normal text? E.g.: // Try to parse type. parsedType = tryParse(type); In the comment, "type" is the name of the variable. Do you mark it in any way to signify that it's a symbol and not just part of the comment's text? I've seen things like this: // Try to parse "type". // Try to parse 'type'. // Try to parse *type*. // Try to parse <type>. // Try to parse [type]. And also: // Try to parse variable type. (I don't think the last one is very helpful; it's a bit confusing; you could think "variable" is an adjective there) Do you have any preference? I find that I need to use some kind of marker; otherwise the comments are sometimes ambiguous, or at least force you to reread them when you realise a particular word in the comment was actually the name of a variable. (In comments that will appear in the documentation I use the appropriate tags for the generator, of course: @code, <code></code>, etc) Thanks!

  • Sphinx - delimiters

    - by yoda
    Hi, I would like to know if the Sphinx engine works with any delimiters (like commas and periods in normal MySQL). My question comes from the urge, not to use them at all, but to escape them or at least thay they don't enter in conflict when performing MATCH operations with FULLTEXT searches, since I have problems dealing with them in MySQL by default and I would prefer not to be forced to replace those delimiters by any other characters to provide a good set of results. Sorry if I'm saying something stupid, but I don't have experience with Sphinx or other complementary (?) search engines. To give you an example, if I perform a search with "Passat 2.0 TDI" MySQL by default would identify the period in this case as a delimiter and since the "2" and "0" are too short to be considered words by default, the results would be a bit messed up. Is it easy to handle with Sphinx (or other search engine)? I'm open to suggestions. This is for a large project, with probably more than 500.000 possible records (not trivial at all). Cheers!

  • Regex Replacing only whole matches

    - by Leen Balsters
    I am trying to replace a bunch of strings in files. The strings are stored in a datatable along with the new string value. string contents = File.ReadAllText(file); foreach (DataRow dr in FolderRenames.Rows) { contents = Regex.Replace(contents, dr["find"].ToString(), dr["replace"].ToString()); File.SetAttributes(file, FileAttributes.Normal); File.WriteAllText(file, contents); } The strings look like this _-uUa, -_uU, _-Ha etc. The problem that I am having is when for example this string "_uU" will also overwrite "_-uUa" so the replacement would look like "newvaluea" Is there a way to tell regex to look at the next character after the found string and make sure it is not an alphanumeric character? I hope it is clear what I am trying to do here. Here is some sample data: private function _-0iX(arg1:flash.events.Event):void { if (arg1.type == flash.events.Event.RESIZE) { if (this._-2GU) { this._-yu(this._-2GU); } } return; } The next characters could be ;, (, ), dot, comma, space, :, etc.

  • JDBC programms running long time performance issue

    - by phyerbarte
    My program has an issue with Oracle query performance, I believe the SQL have good performance, because it returns quickly in SQLPlus. But when my program has been running for a long time, like 1 week, the SQL query (using JDBC) becomes slower (In my logs, the query time is much longer than when I originally started the program). When I restart my program, the query performance comes back to normal. I think it is could be something wrong with the way I use the preparedStatement, because the SQL I'm using does not use placeholders "?" at all. Just a complex select query. The query process is done by a util class. Here is the pertinent code building the query: public List<String[]> query(String sql, String[] args) { Connection conn = null; conn = openConnection(); conn.setAutocommit(true); .... PreparedStatement preStatm = null; ResultSet rs = null; ....//set preparedstatment arg code rs = preStatm.executeQuery(); .... finally{ //close rs //close prestatm //close connection } } In my case, the args is always null, so it just passes a query sql to this query method. Is that possible this way could slow down the DB query after program long time running? Or I should use statement instead, or just pass args with "?" in the SQL? How can I find out the root cause for my issue? Thanks.

  • Fragments keep going back to the default position when MapView is Zoomed In/Out

    - by hectichavana
    I have an activity with 3 fragments displayed, a MapActivity, a ListActivity, and a (normal) DetailsActivity. The ListActivity and DetailsActivity is placed over the MapActivity. There's a function to hide both ListActivity and DetailsActivity with an Animation, and onAnimationEnd() I set a new layout for the hidden Activity. The problem I'm facing is, everytime one of the ListActivity or DetailsActivity hidden (picture State 2), and then I pinch the screen on the MapActivity to zoom the map, it always goes back to the default view (picture State 1). The closed Activities are automatically opened again. Does anybody know how to prevent the hidden fragments from going to the first state again when I pinch the MapActivity? this is an example of the function how I hide the DetailsActivity(): public void hideDetailview() { final Animation close = AnimationUtils.loadAnimation(this, R.anim.close); close.setFillEnabled(true); close.setAnimationListener(closeDetailAnimationListener); fragment_detail.startAnimation(close); Toast.makeText(MainFragmentActivity.this,WWHApplication.getDrawer(), Toast.LENGTH_SHORT).show(); } private AnimationListener closeDetailAnimationListener = new AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { int newLeft = -330; fragment_detail.layout(newLeft, fragment_detail.getTop(), newLeft + fragment_detail.getMeasuredWidth(), fragment_detail.getTop() + fragment_detail.getMeasuredHeight()); } };

In Webkit browsers like Chrome and Safari, it's pushed down a couple more pixels. What's the prob? Thanks.

  • IIS 6.0 Rewrite rules for Wordpress (Forward slash not working and other things)

    - by DigitalBlade
    Hi, I am using Wordpress 3.0.4 on IIS 6.0 and Windows Server 2003, hosted by a company. I was having lots of issues using permalinks. I have fixed most, but now I have an issue with a forward-slash not being added to the address. This would be fine on most websites, but not on IIS for some reason. Specifically, if I go to "mysite.com/wp-admin" I can log-in and get to the dashboard, but as soon as I click anything there i am redirected to a broken link. For example: "mysite.com/post-new.php". If I add the slash at the end it's fine. So I tried to have a rewrite rule to automatically add the slash to such address: RewriteRule /wp-admin /wp-admin/ [L] But it still doesn't work. For your reference, here's the complete file: [ISAPI_Rewrite] RewriteBase / RewriteCond ${REQUEST_FILENAME} !-f RewriteCond ${REQUEST_FILENAME} !-d # For special WordPress folders (e.g. theme, admin, etc.) RewriteRule /wp-admin /wp-admin/ [L] RewriteRule /wp-(.*) /wp-$1 [L] RewriteRule /(.*\.(?:jpg|jpeg|gif|css|txt|xml|html|png|js)) /$1 [I,L] # Rules to ensure that normal content gets through RewriteRule /images/(.*) /images/$1 [L] RewriteRule /favicon.ico /favicon.ico [L] RewriteRule /robots.txt /robots.txt [L] RewriteRule /phpmyadmin/(.*) /phpmyadmin/$1 [L] RewriteRule /phpmyadmin /phpmyadmin/ [L] # For all WordPress pages RewriteRule ^/$ /index.php [L] RewriteRule /(.*) /index.php/$1 [L] Any ideas? Thanks in advance

  • Java RSA Encrypt using .NET XML Key File - need help

    - by badMonkey
    In .net I have generated the following public key file: <RSAKeyValue> <Modulus>xTSiS4+I/x9awUXcF66Ffw7tracsQfGCn6g6k/hGkLquHYMFTCYk4mOB5NwLwqczwvl8HkQfDShGcvrm47XHKUzA8iadWdA5n4toBECzRxiCWCHm1KEg59LUD3fxTG5ogGiNxDj9wSguCIzFdUxBYq5ot2J4iLgGu0qShml5vwk=</Modulus> <Exponent>AQAB</Exponent> .NET is happy to encrypt using it's normal methods. I am trying to use this key to encode a string in Java and am running into an Arithmetic problem (exception) when I attempt to encrypt the string. The following is the code I am using to encrypt: byte[] modulusBytes = Base64.decode(this.getString(R.string.public_key_modulus)); byte[] exponentBytes = Base64.decode(this.getString(R.string.public_key_exponent)); BigInteger modulus = new BigInteger( modulusBytes ); BigInteger exponent = new BigInteger( exponentBytes); RSAPublicKeySpec rsaPubKey = new RSAPublicKeySpec(modulus, exponent); KeyFactory fact = KeyFactory.getInstance("RSA"); PublicKey pubKey = fact.generatePublic(rsaPubKey); Cipher cipher = Cipher.getInstance("RSA"); cipher.init(Cipher.ENCRYPT_MODE, pubKey); byte[] cipherData = cipher.doFinal( new String("big kitty dancing").getBytes() ); It is the final line in the code block that fails. I have looked at numerous examples and this is the best I could come up with. If it is not obvious, the R.string.public_key_modulus is a copy/paste of the text in the Modulus element, same applies for exponent.

  • How to create anroid to send to work in my place?

    - by aj-sin-dhal
    Hi I would like to create a life like android/robot to send to work in my place. Requirements 1) People should not be able to tell the difference between me and the android. My first attempt may not be perfect but I can tell people that its my twin that was dropped on its head while we were growing up. 2) Should have the same weight as me so it won't crush small children if it falls over. By small children I mean those above 7 years old. Those below 7 can easily be crushed by a normal human adult so it is not important to consider that special case. 3) Should run on linux. I have a tight budget and cannot afford to pay for any propreitary operating system. Will consider writing my own operating system if this is the best way to go. I am reading "The design of the unix operating system" by Maurice J. Bach currently. That should be useful. I also have an old copy of the dragon book. What other books should I read? I would like to finish this by monday if possible. I don't like working on mondays. I have made a start and have picked some clothes and shoes for my android worker. Any help will be appreciated. This is a serious question. AJ

  • How can I override list methods to do vector addition and subtraction in python?

    - by Bobble
    I originally implemented this as a wrapper class around a list, but I was annoyed by the number of operator() methods I needed to provide, so I had a go at simply subclassing list. This is my test code: class CleverList(list): def __add__(self, other): copy = self[:] for i in range(len(self)): copy[i] += other[i] return copy def __sub__(self, other): copy = self[:] for i in range(len(self)): copy[i] -= other[i] return copy def __iadd__(self, other): for i in range(len(self)): self[i] += other[i] return self def __isub__(self, other): for i in range(len(self)): self[i] -= other[i] return self a = CleverList([0, 1]) b = CleverList([3, 4]) print('CleverList does vector arith: a, b, a+b, a-b = ', a, b, a+b, a-b) c = a[:] print('clone test: e = a[:]: a, e = ', a, c) c += a print('OOPS: augmented addition: c += a: a, c = ', a, c) c -= b print('OOPS: augmented subtraction: c -= b: b, c, a = ', b, c, a) Normal addition and subtraction work in the expected manner, but there are problems with the augmented addition and subtraction. Here is the output: >>> CleverList does vector arith: a, b, a+b, a-b = [0, 1] [3, 4] [3, 5] [-3, -3] clone test: e = a[:]: a, e = [0, 1] [0, 1] OOPS: augmented addition: c += a: a, c = [0, 1] [0, 1, 0, 1] Traceback (most recent call last): File "/home/bob/Documents/Python/listTest.py", line 35, in <module> c -= b TypeError: unsupported operand type(s) for -=: 'list' and 'CleverList' >>> Is there a neat and simple way to get augmented operators working in this example?

  • Problem with reading and writing to binary file in C++

    - by Reem
    I need to make a file that contains "name" which is a string -array of char- and "data" which is array of bytes -array of char in C++- but the first problem I faced is how to separate the "name" from the "data"? newline character could work in this case (assuming that I don't have "\n" in the name) but I could have special characters in the "data" part so there's no way to know when it ends so I'm putting an int value in the file before the data which has the size of the "data"! I tried to do this with code as follow: if((fp = fopen("file.bin","wb")) == NULL) { return false; } char buffer[] = "first data\n"; fwrite( buffer ,1,sizeof(buffer),fp ); int number[1]; number[0]=10; fwrite( number ,1,1, fp ); char data[] = "1234567890"; fwrite( data , 1, number[0], fp ); fclose(fp); but I didn't know if the "int" part was right, so I tried many other codes including this one: char buffer[] = "first data\n"; fwrite( buffer ,1,sizeof(buffer),fp ); int size=10; fwrite( &size ,sizeof size,1, fp ); char data[] = "1234567890"; fwrite( data , 1, number[0], fp ); I see 4 "NULL" characters in the file when I open it instead of seeing an integer. Is that normal? The other problem I'm facing is reading that again from the file! The code I tried to read didn't work at all :( I tried it with "fread" but I'm not sure if I should use "fseek" with it or it just read the other character after it. Forgive me but I'm a beginner :(

  • WIN32 Logon question

    - by Lalit_M
    We have developed a ASP.NET 3.5 web application with Web Server 2008 and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. I need to get the token back after the authentication (authenticated \ password locked \ wrong password ) its futher use and based on logic showing different web pages Has anyone seen this behavior with the Win32 LogonUser method? Please answer the following issue: Is it possible to disable this behavior to create the folder as taking 2.78 MB of space for every new user and it eating my disck space? I have tried LOGON32_LOGON_BATCH but it was giving an error 1385 in authentication user. For any solution related to LOGON32_LOGON_BATCH, can you please confirm if that will stop creating the folders at location C:\users. Also for any possible solution I need either I am able to disable the folder to be created at C:\user or Any other option to authenticated user which will not creat folders.

  • How to get a checkout-able revision info from subversion?

    - by zhongshu
    I want to check a svn url and to get the latest revision, then checkout it, I don't want to use HEAD because I will compare the latest revision to others. so I use "svn info" to get the "Last Changed Rev" for the url like this: D:\Project>svn info svn://.../branches/.../path Path: ... URL: svn://.../branches/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2400 Node Kind: directory Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 but, I found the 2396 revision is not checkout-able, because this path is in a branch copied from trunk, and the 2396 is the revision modified in the trunk. so when I use svn checkout -r 2396, I will get a workcopy for the path in the trunk, then I can not do checkin for the branch. D:\Project>svn checkout svn://.../branches/.../path -r 2396 workcopy ..... ..... D:\Project>svn info workcopy Path: workcopy URL: svn://.../trunk/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2396 Node Kind: directory Schedule: normal Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 So, my question is how to get a checkout-able revision for the branch path, for this example, I want to get 2397 (because 2397 is the revision which copy occur). And I know "svn log" can get the info, but "svn log" output maybe very long and parse it will be difficult than "svn info". I just want know which revision is the latest checkout-able revision for the path.

  • How do I capture Chinese input via SCIM with STDIN in Perl?

    - by KCArpe
    I use SCIM on Linux for Chinese and Japanese language input. Unfortunately, when I try to capture input using Perl's STDIN, the input is crazy. As roman characters are typed, SCIM tries to guess the correct final characters. ^H (backspace) codes are used to delete previously suggested chars on the command line. (As you type, SCIM tries to guess final Asian chars and displays them.) However, these backspace chars are shown literally as ^H and not interpreted correctly. Example one-liner: perl -e 'print "Chinese: "; my $s = <STDIN>; print $s' When I enable SCIM Chinese or Japanese language input, as I type, e.g., nihao = ??, here is the result: ?^H?^H?^H?^H?^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H?? At the very end of this string, you can see "??" (nihao/hello). At a normal bash prompt, if I type nihao (with Chinese enabled), the results is perfect. This has something to do with interpretation of backspace chars (or control chars) during Perl's STDIN. The same thing happens when using command 'read' in Bash. Witness: read -p 'Chinese: ' s && echo $s

  • Gearman client doBackground always returns GEARMAN_TIMEOUT

    - by Ascherer
    So, ive got a simple gearman system running right now, with a worker running. The worker basically just takes the payload (a random number in this case, and is supposed to echo it back to the screen. Literally an echo, not returning to the client. The client sends the random number. Im trying to do a $client->doBackground( 'post', 65482, md5(uniqid())); but its coming back with a 47 error (GEARMAN_TIMEOUT) every time. getErrNo() returns 0, error() returns something about GEARMAN_TIMEOUT However, when i change it to just $client->do(blah, blah, blah), it works just fine. I've even occasionally seen it where the worker still echo's the number, even after getting the timeout error... public function execute() { $method = 'do'; if( !$this->getBlock() ) { $method .= ( $this->getPriority() == 'Normal' ? '' : $this->getPriority() ) . 'Background'; } else { $method .= $this->getPriority(); } echo "Method: $method \t Worker: {$this->getName()} \t Payload: {$this->getPayload()} \t Hash: {$this->getHash()}\n"; $this->setResult( $this->getClient() ->$method( $this->getName(), $this->getPayload(), $this->getHash() ) ); if( $this->getClient()->returnCode() != GEARMAN_SUCCESS ) { echo "Code: " . $this->getClient()->returnCode() .

  • Why do you need "extern C" for C++ callbacks to C functions?

    - by Artyom
    Hello, I find such examples in Boost code. namespace boost { namespace { extern "C" void *thread_proxy(void *f) { .... } } // anonymous void thread::thread_start(...) { ... pthread_create(something,0,&thread_proxy,something_else); ... } } // boost Why do you actually need this extern "C"? It is clear that thread_proxy function is private internal and I do not expect that it would be mangled as "thread_proxy" because I actually do not need it mangled at all. In fact in all my code that I had written and that runs on may platforms I never used extern "C" and this had worked as-as with normal functions. Why extern "C" is added? My problem is that extern "C" function pollute global name-space and they do not actually hidden as author expects. This is not duplicate! I'm not talking about mangling and external linkage. It is obvious in this code that external linkage is unwanted! Answer: Calling convention of C and C++ functions are not necessary the same, so you need to create one with C calling convention. See 7.5 (p4) of C++ standard.

  • 1.8.x Ruby on Rails RESTful nested admin page and form_for problems

    - by Loomer
    So I am creating a website that I want to have an admin directory in rails 1.8.x and I'm struggling a bit to get the form_for to link to the right controller. I am trying to be RESTful. What I basically want is an admin page that has a summary of actions which can then administer sub models such as: /admin (a summary of events) /admin/sales (edit sales on the site) /admin/sales/0 (the normal RESTful stuff) I can't use namespaces since they were introduced in Rails 2.0 (production site that I don't want to mess with updating rails and all that). Anyway, what I have in the routes.rb is: map.resource :admin do |admin| admin.resources :sales end I am using the map.resource as a singleton as recommended by another site. The problem comes in when I try to use the form_for to link to the subresource RESTfully. If i do : form_for(:sales, @sale) it never links to the right controller no matter what I try. I have also tried: form_for [@admin, @sale] do |f| and that doe not work either (I am guessing since admin is a singleton which does not have a model, it's just a placeholder for the admin controller). Am I supposed to add a prefix or something? Or something into the sales controller to specify that it is a subcontroller to admin? Is there an easier way to do this without manually creating a bunch of routes? Thanks for any help.

  • Why does JavaScript's getElementsByClassName provide an object that is NOT an array?

    - by Paragon
    I'm trying to get a list in JavaScript (not using jQuery) of all the elements on the page with a specific class name. I therefore employ the getElementsByClassName() function as follows: var expand_buttons = document.getElementsByClassName('expand'); console.log(expand_buttons, expand_buttons.length, expand_buttons[0]); Note that I have three anchor elements on my page with the class 'expand'. This console.log() outputs [] 0 undefined Next, for kicks, I threw expand_buttons into its own array as follows: var newArray = new Array(expand_buttons); console.log(newArray, newArray.length); This suddenly outputs [NodeList[3]] 1 and I can click through the nodelist and see the attributes of the three 'expand' anchor elements on the page. It's also worth noting that I was able to get my code working in a w3schools test page. It may also be of note that my use of document.getElementsByName actually does output (to the console) an array of elements, but when I ask for its length, it tells me 0. Similarly, if I try to access an array element using array_name[0] as normal, it outputs 'undefined', despite there clearly being an element inside of an array when I print the object to the console. Does anybody have any idea why this might be? I just want to loop through DOM elements, and I'm avoiding jQuery at the moment because I'm trying to practice coding with vanilla JavaScript. Thanks, ParagonRG

  • How to import a module from PyPI when I have another module with the same name

    - by kuzzooroo
    I'm trying to use the lockfile module from PyPI. I do my development within Spyder. After installing the module from PyPI, I can't import it by doing import lockfile. I end up importing anaconda/lib/python2.7/site-packages/spyderlib/utils/external/lockfile.py instead. Spyder seems to want to have the spyderlib/utils/external directory at the beginning of sys.path, or at least none of the polite ways I can find to add my other paths get me in front of spyderlib/utils/external. I'm using python2.7 but with from __future__ import absolute_import. Here's what I've already tried: Writing code that modifies sys.path before running import lockfile. This works, but it can't be the correct way of doing things. Circumventing the normal mechanics of importing in Python using the imp module (I haven't gotten this to work yet, but I'm guessing it could be made to work) Installing the package with something like pip install --install-option="--prefix=modules_with_name_collisions" package_name. I haven't gotten this to work yet either, but I'm guess it could be made to work. It looks like this option is intended to create an entirely separate lib tree, which is more than I need. Source Using pip install --target=lockfile_from_pip. The files show up in the directory where I tell them to go, but import doesn't find them. And in fact pip uninstall can't find them either. I get Cannot uninstall requirement lockfile-from-pip, not installed and I guess I will just delete the directories and hope that's clean. Source So what's the preferred way for me to get access to the PyPI lockfile module?

  • Javascript function working strangely during the first call in CHROME ?

    - by Sohil
    HI all, Below mentioned javascript code works fine in all browsers including chrome(from second call onwards). function call(val){ url = window.location.href; indexnum = url.lastIndexOf("/"); str = url.slice(indexnum+1); window.location.href = url.replace(str, "sample.php?src_q=") + val; } I am calling this function on onclick of a link as below <?php echo "<a href='#' onclick='javascript:call(\"$fieldvalue\");'>$fieldvalue</a>" ?> Normal Behaviour : In all browser after clicking on the link new formed url is url://localhost/mysite/sample.php?src_q=val Strange Behaviour : When I click on the link for the first time in chrome value of variable val gets replaced by url and its value as follows http://localhost/mysite/sample.php?src_q=http://localhost/mysite/val This strange behaviour happens during the first click in chrome. From the second call onwards in the same tab, the value of variable val works fine and I get desired url. I tried to google on it, but couldn't found any explanation. Thanks in advance.

  • Photoshop CS4. How do I make sure my color stays the same in my different .psd files? (could be RGB

    - by Kris
    I asked 2 photoshop experts I know but they haven't got a clue because all my settings are exactly the same, in both files. (except the RGB type !! I'm not sure. Please read on) I use RGB color, 72DPI, 8 bits / channel. No adjustments (filters, like greyscale, etc ...) are selected / used. The layers are both normal, and opacity and fill are 100% (yes, in both files). I took two screenshots, and you can see the difference: http://www.flickr.com/photos/30465871@N05/4623864297/ http://www.flickr.com/photos/30465871@N05/4624469754/ Both colors are ff795d, but that doesn't matter, any color I use gives me the same problem: they both look different. Now, I know the CMYK settings (see screenshots) are different, but when the settings are the same the color changes. Why is this happening and how do I solve this problem? My guess is I'm working with different a type of RGB. It's sRGB IE61966 - 2.1 in the file I created (file info raw data) but I can't find that in the file that started with a screenshot. If that's the problem, how do I change / convert the RGB, once the file is already open? Thank you.

  • Predicate usually used for array/list how about here?

    - by amit kohan
    In following code (Josh Smith's article on MVVM), can somebody give me some insight about return _canExecute == null ? true : _canExecute(parameter); ? it is a normal if/else statement but I'm not getting the last part of it. public class RelayCommand : ICommand { #region Fields readonly Action<object> _execute; readonly Predicate<object> _canExecute; #endregion // Fields #region Constructors public RelayCommand(Action<object> execute) : this(execute, null) { } public RelayCommand(Action<object> execute, Predicate<object> canExecute) { if (execute == null) throw new ArgumentNullException("execute"); _execute = execute; _canExecute = canExecute; } #endregion // Constructors #region ICommand Members [DebuggerStepThrough] public bool CanExecute(object parameter) { return _canExecute == null ? true : _canExecute(parameter); } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } public void Execute(object parameter) { _execute(parameter); } #endregion // ICommand Members } Thanks.
