  • jQuery - change a list of elements to an associative array

    - by Brian M. Hunt
    Given an associative array (of the sort returned by jQuery.serializeArray()) like this: [ { 'name': 'abc', 'value': 'aaa', '__proto__': [Object] }, { 'name': 'def', 'value': 'bbb', '__proto__': [Object] }, { 'name': 'abc', 'value': 'ccc', '__proto__': [Object] } ] How can one convert this, using either jQuery or just javascript, to an associative array of name: [values] like this: { 'abc': ['aaa', 'ccc'], 'def': ['bbb'] } This seems to essentially be the inverse of this question: Build associative array based on values of another associative array... but in Javascript (not PHP). I wasn't able to find this question on Stackoverflow, though I thought it would have been asked. Thank you for reading. Brian

  • Populating PHP list() with values in an array.

    - by Mike
    Hi, I have an array: $arr = array('foo', 'bar', 'bash', 'monkey', 'badger'); I want to have the elements in that array appear as the variables in my list(): list($foo, $bar, $bash, $monkey, $badger) = $data; Without actually specifying the variables, I tried; list(implode(",$", $arr)) = $data; and list(extract($arr)) = $data; But they don't work, I get: Fatal error: Can't use function return value in write context Does anyone have any idea whether this is possible? Cheers, Mike

  • PHP array include performance

    - by tau
    What type of performance hit can I expect if I include a huge PHP array? For example, lets say I have a 1GB PHP array in "data.php" that looks like $data = array( //1GB worth of data ) If I include that huge "data.php" file on "header.php", how will it affect the performance of "header.php" when it executes? Thanks!

  • faster way to change xml to array(grails to flex)

    - by Anthony Umpad
    I have a large xml passed from grails to flex. When flex receives the xml, it converts the xml into an associative array object. Given the large xml file, it takes too long to complete the loop, is there any way in flex to make conversion faster? Below is my sample code. <xml> <car> <model>Vios</model> <type>Sedan</type> <color>Blue</color> </car> <car> <model>Camry</model> <type>Luxury</type> <color>Black</color> </car> </xml> *converted to the flex associative array below.* [Vios].type = Sedan .color = Blue [Camry].type = Luxury .color = Black *Below is a code I used in flex to convert the xml to the associative array object* var tempXML=xml.children() var tempArray:Array= new Array() for(var i:int=0;i<tempXML.length();i++) { tempArray[tempXML[i].@model]= new Object(); tempArray[tempXML[i].@model].color = tempXML[i][email protected](); tempArray[tempXML[i].@model].type = tempXML[i][email protected](); }

  • C++ Array Initialization in Function Call or Constructor Call

    - by david
    This question is related to the post here. Is it possible to initialize an array in a function call or constructor call? For example, class foo's constructor wants an array of size 3, so I want to call foo( { 0, 0, 0 } ). I've tried this, and it does not work. I'd like to be able to initialize objects of type foo in other objects' constructor initialization lists, or initialize foo's without first creating a separate array. Is this possible?

  • array size for extendible hashing

    - by Phenom
    If I want to use extendible hashing to store a maximum of 100 records, then what is the minimum array size that I need? I am guessing that an array of 100 would be sufficient, but I could be wrong. I also suspect that I can use a smaller array.

  • Writing/Reading struct w/ dynamic array through pipe in C

    - by anrui
    I have a struct with a dynamic array inside of it: struct mystruct{ int count; int *arr; }mystruct_t; and I want to pass this struct down a pipe in C and around a ring of processes. When I alter the value of count in each process, it is changed correctly. My problem is with the dynamic array. I am allocating the array as such: mystruct_t x; x.arr = malloc( howManyItemsDoINeedToStore * sizeof( int ) ); Each process should read from the pipe, do something to that array, and then write it to another pipe. The ring is set up correctly; there's no problem there. My problem is that all of the processes, except the first one, are not getting a correct copy of the array. I initialize all of the values to, say, 10 in the first process; however, they all show up as 0 in the subsequent ones. for( j = 0; j < howManyItemsDoINeedToStore; j++ ){ x.arr[j] = 10; } Initally: 10 10 10 10 10 After Proc 1: 9 10 10 10 15 After Proc 2: 0 0 0 0 0 After Proc 3: 0 0 0 0 0 After Proc 4: 0 0 0 0 0 After Proc 5: 0 0 0 0 0 After Proc 1: 9 10 10 10 15 After Proc 2: 0 0 0 0 0 After Proc 3: 0 0 0 0 0 After Proc 4: 0 0 0 0 0 After Proc 5: 0 0 0 0 0 Now, if I alter my code to, say, struct mystruct{ int count; int arr[10]; }mystruct_t; everything is passed correctly down the pipe, no problem. I am using READ and WRITE, in C: write( STDOUT_FILENO, &x, sizeof( mystruct_t ) ); read( STDIN_FILENO, &x, sizeof( mystruct_t ) ); Any help would be appreciated. Thanks in advance!

  • Showing an array of certain pages with WP_Query in Wordpress

    - by Ragnar
    What I'm trying to achieve is showing only certain pages in a loop. 3 certain pages, not more, not less. I've tried many things but I just can't complete it. <?php $special_tabs = new WP_Query(array('post_type' => 'page', 'post_in' => array(100,102,104))); ?> What this does, from what I understand, is that it shows an array of pages and then includes those ID's there as well. <?php $special_tabs = new WP_Query(array ('page_id' => 100)); ?> And this shows only ONE certain page, it doesn't support the showing of array of different IDs. I'm sure I am not the first person to have such specific needs and I'm certain there is a relatively simple way to achieve what I'm trying to achieve, but I just can't come up with a solution or to find one. Can anybody please help me with this? Many thanks in advance!

  • php compare array keys, not values

  • Capture String from Array, C#

    - by Dan Snyder
    I'm trying to figure out how to get a string from an array starting at some given position. Say we have an array that's arbitrarily long and my string starts at location 1000. If I wanted to get a string from a file I would simply use something like getc or scanf or something. How do I carry out these same functions on an array instead of a file? *oh, keep in mind that the array is of type int and is full of numerical representations of ASCII characters.

  • [PHP] Condition for array with string as keys

    - by Kel
    My PL/SQL procedure returns a cursor. It always returns data. I fetch (oci_fetch_assoc) it and save it in an array. If results were found the keys of the array will be strings. If the cursor didn't find data, it will return value 0, thus the key of the array will be numeric. while($data = oci_fetch_assoc($cursor)){ if(!isset($data[0])){ ... } ... ... } What's the best way to check that the array is not just 0, but contains data? Thanks

  • Fast serarch of 2 dimensional array

    - by Tim
    I need a method of quickly searching a large 2 dimensional array. I extract the array from Excel, so 1 dimension represents the rows and the second the columns. I wish to obtain a list of the rows where the columns match certain criteria. I need to know the row number (or index of the array). For example, if I extract a range from excel. I may need to find all rows where column A =”dog” and column B = 7 and column J “a”. I only know which columns and which value to find at run time, so I can’t hard code the column index. I could use a simple loop, but is this efficient ? I need to run it several thousand times, searching for different criteria each time. For r As Integer = 0 To UBound(myArray, 0) - 1 match = True For c = 0 To UBound(myArray, 1) - 1 If not doesValueMeetCriteria(myarray(r,c) then match = False Exit For End If Next If match Then addRowToMatchedRows(r) Next The doesValueMeetCriteria function is a simple function that checks the value of the array element against the query requirement. e.g. Column A = dog etc. Is it more effiecent to create a datatable from the array and use the .select method ? Can I use Linq in some way ? Perhaps some form of dictionary or hashtable ? Or is the simple loop the most effiecent ? Your suggestions are most welcome.

  • Javascript array of dates - not iterating properly (jquery ui datepicker)

    - by PaulB
    Hi I have some code which builds an array of date ranges. I then call a function, passing it a date, and compare that date with dates in the array. I'm doing it this way because the dates are stored in a cms, and I'm manipulating the JqueryUI datepicker. Unfortunately my code only checks the first date range in the array - and I can't figure out why! I think it's probably something simple (/stupid!) - if anyone can shed some light on it I'd be extremely grateful! The code is below - the june-september range works fine, the december to jan is totally ignored... <script type="text/javascript" language="javascript"> var ps1 = new Date(2010, 06-1, 18); var pe1 = new Date(2010, 09-1, 03); var ps2 = new Date(2010, 12-1, 20); var pe2 = new Date(2011, 01-1, 02); var peakStart = new Array(ps1,ps2); var peakEnd = new Array(pe1,pe2); function checkDay(date) { var day = date.getDay(); for (var i=0; i<peakStart.length; i++) { if ((date > peakStart[i]) && (date < peakEnd[i])) { return [(day == 5), '']; } else { return [(day == 1 || day == 5), '']; } } } </script>
