associative

I am trying to create an array in javascript which will allow me to access data like this: var name = infArray[0]['name']; however I cant seem to get anything to work in this way. When i passed out a assoc array from php to javascript using json_encode it structured the data in this way. The reason why i have done this is so i can pass back the data in the same format to php to execute an update sql request. JavaScript doesn't have associative arrays. It has (numeric) arrays and objects. What you want is a mix of both. Something like this: var infArray = [{ name: 'Test', hash: 'abc' }, { name:

I have searched on here for a quality method to compare associative arrays in javascript. The only decent solution I have found is the PHP.JS project which has some comparative array functions. The only problem is that these functions consider the first array as the key to the second. In my situation at least both arrays do not always have the same # of keys nor the same keys. This causes the functions to output results that do not include keys that may not have existed in array1 but existed in array2. The only thing I can think of so far is to run the array_diff_associative() function twice

I saw a very good sample here: Subclass UIButton to add a property What is it? You can't add object to a category. But now with this trick you can. So what is it? How does it work? Objective-c object already have some constant number of ivar pointers right? Now you add another one? How did they figure that out? A pretty ugly notation I must admit. With the Associative References trick, you're not actually adding any instance data to the UIButton object . Instead, you're using a totally separate Cocoa facility to create a new dictionary mapping (or associating ) existing UIButton objects with

I have a simple simulated aarray with two elements: bowl["fruit"]="apple"; bowl["nuts"]="brazilian"; I can access the value with an event like this: onclick="testButton00_('fruit')">with `testButton00_` function testButton00_(key){ var t = bowl[key]; alert("testButton00_: value = "+t); } However whenever I try to access the aarray from within code with a key that is just a non-explicit string I get undefined. Do I have somehow have to pass the parameter with the escaped 'key'. Any ideas? tia. The key can be a dynamically computed string. Give an example of something you pass that doesn't work.

What is the fastest way to convert a simple array to an associative array in PHP so that values can be checked in the isset($array[$value]) ? I.e. fastest way to do the following conversion: $array = array(1, 2, 3, 4, 5); $assoc = array(); foreach ($array as $i => $value) { $assoc[$value] = 1; } array_flip() is exactly doing that: array_flip() returns an array in flip order, i.e. keys from trans become values and values from trans become keys. Note that the values of trans need to be valid keys, i.e. they need to be either integer or string . A warning will be emitted if a value has the wrong

I have an array that looks just like that: array(3) { ["fk_article_id"]=> string(1) "4" ["first_name"]=> string(6) "Ulrike" ["last_name"]=> string(10) "Grasberger" } array(3) { ["fk_article_id"]=> string(1) "9" ["first_name"]=> string(5) "Frank" ["last_name"]=> string(9) "Neubacher" } array(3) { ["fk_article_id"]=> string(3) "896" ["first_name"]=> string(2) "D." ["last_name"]=> string(5) "Bauer" } array(3) { ["fk_article_id"]=> string(3) "896" ["first_name"]=> string(2) "S." ["last_name"]=> string(6) "Anders" } array(3) { ["fk_article_id"]=> string(3) "896" ["first_name"]=> string(2) "M." [

I'm trying to create dynamic breadcrumbs from an array. So I can add to the array and not have to manually update the breadcrumbs. Okay, here's a snippet of my array: (It won't go much deeper) $menu = array( 'Dashboard' => array( 'Projects' => array( 'Project 1' => array( 'Project settings' => 'projects/project_1/settings', 'Issue Tracker' => 'projects/project_1/issue_tracker', 'Customize page' => 'projects/project_1', 'Manage files' => 'projects/project_1/files', ), 'Project 2' => array( 'Project settings' => 'projects/project_2/settings', 'Issue Tracker' => 'projects/project_2/issue_tracker'
