  • To not iterate through function of Array object if it is added to Array prototype

    - by Rishat Muhametshin
    According to the way to add indexOf method to Array class in IE6, how do I now reject this method from iterating through any random array? For example: Array.prototype.indexOf = function(needle) { ... }; var array = [1, 2, 3]; for (var i in array) { document.write(i + ': ' + array[i]); } gives output 0: 1 1: 2 2: 3 indexOf: function ... How can I skip indexOf property and stop iterating on it without adding any code to where for(...) is called?

  • sending javascript array to external php file using POST

    - by user1472224
    I am trying to send a javascript array to an external php page, but the only thing the php page is picking up is the fact that I am sending array, not the actual data within the array. javascript - var newArray = [1, 2, 3, 4, 5]; $.ajax({ type: 'POST', url: 'array.php', data: {'something': newArray}, success: function(){ alert("sent"); } }); External PHP Page - <?php echo($_POST['something'])); ?> I know this question has been asked before, but for some reason, this isn't working for me. I have spent the last couple days trying to figure this out as well. Can someone please point me in the right direction. current output (from php page) - Array (thats all the page outputs)

  • Dividing numbers between rows in MySQL + PHP

    - by André Figueira
    Hi I am working on a kind of raffle system which divides 1 million random numbers into an x amount of tickets, e.g. 1 million random numbers to 10,000 tickets. Each ticket is a row in a database, we then have another table ticket numbers in which i need to give 100 numbers to each ticket they are related by the ticket id. So at the moment this is my code: //Amount of the 1 million tickets divided to the tickets $numbersPerTickets = $_POST['numbersPerTicket']; //The total cost of the property $propertyPrice = $_POST['propertyPrice']; //The total amount of tickets $totalTickets = NUMBER_CIELING / $numbersPerTickets; //The ticket price $ticketPrice = $propertyPrice / $totalTickets; //Generate array with random numbers up to 999,999 $randomTicketNumbers = createTicketNumbers(); //Creation loop counter $ticketCreationCount = 1; //Loop and create each ticket while($ticketCreationCount <= $totalTickets) { //Create a padded ticket number $ticketNumber = str_pad($ticketCreationCount, 6, 0, STR_PAD_LEFT); $query = ' INSERT INTO tickets( propertyID, ticketNumber, price ) VALUES( "'.$propertyID.'", "'.$ticketNumber.'", "'.$ticketPrice.'" ) '; $db->query($query); //Get the ID of the inserted ticket to use to insert the ticket numbers $ticketID = $db->insert_id; $loopBreak = $numbersPerTickets; $addedNumberCount = 1; foreach($randomTicketNumbers as $key => $value) { $query = ' INSERT INTO ticketNumbers( ticketID, number ) VALUES( "'.$ticketID.'", "'.$value.'" ) '; $db->query($query); unset($randomTicketNumbers[$key]); if($addedNumberCount == $loopBreak){ break; }else{ $addedNumberCount++; } } $ticketCreationCount++; } But this isn't working it adds the right amount of tickets, which in the case for testing is 10,000 but then adds far too many ticket numbers, it ends up exceeding the million numbers in the random tickets array, The random tickets array is just a simple 1 tier array with 1 million numbers sorted randomly.

  • Read char from txt file in C++

    - by Jack in the Box
    I have a program that will read the number of rows and columns from a txt file. Also, the program has to read the contents of a 2D array from the same file. Here is the txt file 8 20 * * *** *** 8 and 20 are the number of rows and columns respectively. The spaces and asterisks are the contents of the array, Array[8][20] For example, Array[0][1] = '*' I did make the program reading 8 and 20 as follow: ifstream myFile; myFile.open("life.txt"); if(!myFile) { cout << endl << "Failed to open file"; return 1; } myFile >> rows >> cols; myFile.close(); grid = new char*[rows]; for (int i = 0; i < rows; i++) { grid[i] = new char[cols]; } Now, how to assign the spaces and the asterisks to to the fields in the array? I hope you got the point.

  • javascript array/object issue

    - by FlyingCat
    I am trying to push elements to an array. for (a=0; a < test.length; a++){ if(this.testnumber != test[a].number){ //it will only loop 8 times under conditional statement group = { title: test.Title , ID: test.ID, contents: [] }; this.company.push(group); this.testnumber = test.number[a]; } //outside of if conditional statement.. it will loop 15 times //i want every test[a].conetents get pushed to group.contents array. //this.company is the final variable I need for this function... group.contents.push(test[a].contents); } However, when I do console.log(this.company); I see 8 elmements with only 1 element in each group.contents array The ideal situation is to have 8 elements with 2 to 3 elements in the group.contents array I hope I explain my situation well. Any idea how to solve my issue? Thanks a lot!

  • Append to the end of a Char array in C++

    - by Taylor Huston
    Is there a command that can append one array of char onto another? Something that would theoretically work like this: //array1 has already been set to "The dog jumps " //array2 has already been set to "over the log" append(array2,array1); cout << array1; //would output "The dog jumps over the log"; This is a pretty easy function to make I would think, I am just surprised there isn't a built in command for it. *Edit I should have been more clear, I didn't mean changing the size of the array. If array1 was set to 50 characters, but was only using 10 of them, you would still have 40 characters to work with. I was thinking an automatic command that would essentially do: //assuming array1 has 10 characters but was declared with 25 and array2 has 5 characters int i=10; int z=0; do{ array1[i] = array2[z]; ++i; ++z; }while(array[z] != '\0'); I am pretty sure that syntax would work, or something similar.

  • How to efficiently resize an array of values, without boxing, used within a Dictionary<string, float[]>

    - by makerofthings7
    In the code below, Pages is defined as public SortedDictionary<DateTime, float[]> Pages { get; set; } I am trying to dynamically increase the size of this array. Can anyone tell how to increase the sized of the innermost float[]? var tt = currentContainer.Pages[dateTime]; Array.Resize<float>(ref tt, currentContainer.Pages.Count + 1); Fail 1 I tried the following code and get index out of range exception SortedDictionary<DateTime, float[]> Pages = new SortedDictionary<DateTime,float[]>(); float[] xx = new float[1]; xx[0] = 1; DateTime tempTime = DateTime.UtcNow; Pages.Add(tempTime, xx); var tt = Pages[tempTime]; Array.Resize<float>(ref tt, Pages.Count + 1); Pages[tempTime][1] = 2; Fail 2 The following gives a compile time error (property, index, or dynamic member can't be used as a ref value) SortedDictionary<DateTime, float[]> Pages = new SortedDictionary<DateTime,float[]>(); float[] xx = new float[1]; xx[0] = 1; DateTime tempTime = DateTime.UtcNow; Pages.Add(tempTime, xx); var tt = Pages[tempTime]; // The line below is different from Fail 1 above ... compile time error Array.Resize<float>(ref Pages[tempTime], Pages.Count + 1); Pages[tempTime][1] = 2; Question What is the most performant answer to resize this array? Would the answer change if it's likely that the final size will be 100-200 floats or 700-900 floats? What if I change my allocation size from +1 to +128? .. or larger?

  • C++ - Access array (in main) from methods outside main

    - by John Smith
    I have an array in my main class that holds objects that I need to print out for a menu listing. The array is declared and initialized in main. I need to, however, access the same array in a sub-menu function. If I copy the code (for loop that prints out the values) to the sub-menu, nothing is printed (presumably because it can't access the original array and has made a new, blank one). Is there any way (without making the array a global variable) that I can access the array in this sub-menu? Both the main and the sub-menu function are in the same file and the sub-menu is called from main. Maybe to put it more simply, can I use scope resolution to bring me up one 'level' in scope?

  • Illegal offset type

    - by BFTrick
    Hello, I am having trouble uploading a file through php. I check the file type at the beginning of the process and I get an error. This is the error I am getting: Warning: Illegal offset type in /balblabla/DBfunctions.inc.php on line 183 This is the printed out $_FILES var Array ( [Picture] = Array ( [name] = JPG.jpg [type] = image/jpeg [tmp_name] = /tmp/phpHlrNY8 [error] = 0 [size] = 192221 ) ) Here is the segment of code I am using that is giving me issues: function checkFile($file, $type) { if( in_array($_FILES[$file]['type'], $type) ){ // <--- LINE 183 return true; }//if return false; } // end checkFile() This is the line of code that calls the function if( checkFile( $_FILES['Picture'], array("image/jpeg") ) == true ){ //do stuff }// end if I have used this piece of code on dozens of websites on my own server so i am guessing that this is some different configuration option. How can i modify my code so that it works on this different server?

  • How to copy a subset from an array of strings to an array of ints using Groovy?

    - by Cuga
    I have a String array in a Groovy class (args to a main method): String[] args I'd like to convert the 3rd to the last element into a new array of ints. Is there an easier way to do this in Groovy other than: final int numInts = args.length - 2 final int [] intArray = new int[numInts] for (int i = 2; i < args.length; i++) { intArray[i-2]=Integer.parseInt(args[i]) } I wanted to do: final int numInts = args.length - 2 final int [] intArray = new int[numInts] System.arraycopy(args, 2, intArray, 0, numInts) But it throws a class cast exception. Thanks!

  • Problem with Global Array in PHP

    - by Suezy
    Hi guys,, need some help pls.. i have a PHP code here that lets a user send a message to multiple recipients using the "phonebook" (from database) as the main list. I used an array to temporarily hold all the desired recipients for the current user. So I have a two box, with each for displaying. The user will clicks the name from the phonebook lisy and clicks "Add" button to add on the temporary list on the other select box. The problem is, whenever I use the "onChange" function in javascript; the array accepts only one recipients, and when I try to add, it replaces the first one. :( Here is my code: $recipients = array(); // How do I place the array here? function reload_page(){ i=document.maillinglist.firstletter.selectedIndex; this.location='./group_msg.php?firstletter='+document.maillinglist.firstletter.options[i].value; } function add(){ } $conn = pg_connect("host=localhost user=sa dbname=messaging"); if(isset($_GET['firstletter'])){ $letter=$_GET['firstletter']; } else { $letter='a';} print ""; print "GROUP MESSAGE"; print ""; print ""; print ""; print ""; for($chr_loop=97;$chr_loop<=122;$chr_loop++){ $alphabet = chr($chr_loop); # Displays list of users arranged by letters - this works fine if($alphabet==$letter){ print "\t\t<option value='$alphabet' selected>-------------------- $alphabet --------------------</option>\n"; } else { print "\t\t<option value='$alphabet'>-------------------- $alphabet --------------------</option>\n";} } print ""; print "<td><select style='width:210px' name=\"non_members[]\" size=10 width=200>"; $sql = "select name from test_phonebook where name like '$letter%';"; $result = pg_query($conn, $sql); # Display users from phonebook using the letter chosen while($row = pg_fetch_assoc($result)){ $my_name = $row['name']; print "<option width=200 value=\"$my_name\">$my_name</option>"; } print "</td>"; print "</select>"; print "<td><input type=submit name=add value=\"->>\" onClick=\"add()\"><br><input type=submit name=del value=\"<<-\"></td>"; print "<td><select name=\"members[]\" style='width:210px' size=10>"; # Display temporary recipients - problem: ONLY DISPLAYS ONE VALUE while (list ($key, $val) = each ($recipients)) { echo "$key -> $val <br>"; print "<option width=200 value=\"$val\">$val</option>"; } print "</select></table></form>"; My aim here, is to place all recipients that the user desires to an array, without losing the previous value added.

  • in Python find number of same elements in 2 lists

    - by John
    Hi, In Python if I have 2 lists say: l1 = ['a', 'b', 'c', 'd'] l2 = ['c', 'd', 'e'] is there a way to find out how many elements they have the same. In the case about it would be 2 (c and d) I know I could just do a nested loop but is there not a built in function like in php with the array_intersect function Thanks

  • Android / Java rare and seemingly impossible exception causing force close

    - by Guzba
    Hello all, I have an interesting problem being reported to me from an android application I have published. I have a two-dimensional array that I am iterating through using two for loops like so: for (int i = 0; i < arr.length; ++i) { for (int j = 0; j < arr[i].length; ++j) { if (arr[i][j] != 0) // does stuff } } The problem is, somehow arr[i][j] != 0 is throwing an ArrayIndexOutOfBoundsException. But very rarely. I have thousands of people use the app on a daily basis and get maybe twenty force close reports. Is this something I can't avoid, maybe a problem with the phones memory, etc. or is there something I can do that I haven't thought of yet? Thanks.

  • How to simplify my code... 2D array in Objective C...?

    - by Tattat
    self.myArray = [NSArray arrayWithObjects: [NSArray arrayWithObjects: [self d], [self generateMySecretObject],nil], [NSArray arrayWithObjects: [self generateMySecretObject], [self generateMySecretObject],nil],nil]; for (int k=0; k<[self.myArray count]; k++) { for(int s = 0; s<[[self.myArray objectAtIndex:k] count]; s++){ [[[self.myArray objectAtIndex:k] objectAtIndex:s] setAttribute:[self generateSecertAttribute]]; } } As you can see this is a simple 2*2 array, but it takes me lots of code to assign the NSArray in very first place, because I found that the NSArray can't assign the size at very beginning. Also, I want to set attribute one by one. I can't think of if my array change to 10*10. How long it could be. So, I hope you guys can give me some suggestions on shorten the code, and more readable. thz

  • decode mysql query before returning it to view

    - by stormdrain
    I'm running a query to mysql that returns encrypted data. I'd like, if possible, to decode the results before sending it to the view. It seems like better form to handle the decoding in the controller (or even the model) rather than inside the view. I can't seem to wrap my head around how to do it, though. I was thinking I could iterate through the object, decodode it, and push it to another array that would be sent to the view. Problem with this is I won't know (and need to keep) the indexes of the query. So the query might return something like: [id] => 742 [client_id] => 000105 [last] => dNXcw6mQPaGQ4rXfgIGJMq1pZ1dYAim0 [first] => dDF7VoO37qdtYoYKfp1ena5mjBXXU0K3dDlcq1ssSvCgpOx75y0A== [middle] =>iXy6OWa48kCamViDZFv++K6okIkalC0am3OMPcBwK8sA== [phone] => eRY3zBhAw2H8tKE Any ideas?

  • 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

  • What happens to a class in PHP once its been instantiated?

    - by Caylem
    Hi I'm just playing around with some PHP and was wondering what happens when an object from a class is created within another PHP script? I assume once its created and been processed their is no way of then going back and 'playing' around with it from another script? The idea is i'm trying to create a kind of deck of cards using a card class, each card has specific data that is added to each individual object to make it unique, suit, value etc. Once its created i need to be able to go back to specific cards to use them. In java i'd have an arraylist of card objects, i'm not sure how to approach the same area in PHP. Thanks.
