associative-array

I'm trying to reference the key/value pair of an item in the same array: $glossary_args = array( 'name' => 'Glossary Terms', 'singular_name' => 'Glossary Term', 'add_new' => 'Add New Term', 'edit_item' => 'Edit Term', 'search_items' => 'Search'.$glossary_args["name"], ) Is this even possible? If so, how? You can use the fact that assignment is itself an expression in PHP: $glossary_args = array( 'name' => ($name = 'Glossary Terms'), 'singular_name' => 'Glossary Term', 'add_new' => 'Add New Term', 'edit_item' => 'Edit Term', 'search_items' => 'Search'.$name ) You can't do this when you're first

I've got following XML: <account> <id>123</id> <email></email> <status>ACTIVE</status> </account> I want to have it as an array variable. Therefore I read it with $xml = simplexml_load_file() . The simplest way to convert simpleXMLElement to an associative array I know is to grind it with: json_decode(json_encode((array) $xml),1); The problem is that I don't want to get the email key as an empty array, but rather as a NULL value. As SimpleXMLElement, it looks like: public 'email' => object(SimpleXMLElement)[205] whereas in array it looks like: 'email' => array (size=0) empty I'd like to get:

I have a function called insert which takes two parameters (name, telnumber). When I call this function I want to add to an associative array. So for example, when I do the following: insert("John", "999"); insert("Adam", "5433"); I want to it so be stored like this: [0] { name: John, number: 999 } [1] { name: Adam, number: 5433 } Something like this should do the trick: var arr = []; function insert(name, number) { arr.push({ name: name, number: number }); } Would use something like this; var contacts = []; var addContact = function(name, phone) { contacts.push({ name: name, phone: phone });

How can I do something like the following in JS? I would like to imitate .pop() on an object rather than an array. var deck = { 'cardK' :'13', 'cardQ' :'12', 'cardAJ':'11' }; var val = deck.pop(); console.log("Key" + val.key ); console.log("Value" + val.val ); It seems like it's not possible. .pop is only available on an array. In JavaScript, objects (which are essentially associative arrays) are not ordered like an array, so there is no .pop method. You could use an array: var deck = [ { key: 'cardK', val: 13 }, { key: 'cardQ', val: 12 }, { key: 'cardAJ', val: 11 }, ]; var val = deck.pop();

This is what I have so far and the shoe types are boots, wellingtons, leather, trainers (in that order) I want to iterate through and assign the value so I haves something like var shoeArray = { boots : '3', wellingtons: '0', leather : '1', trainers: '3'}; at the moment I just get an array of {3,0,1,3} which I can work with but it is not very helpful. function shoe_types() { var shoeArray = []; $('[type=number]').each(function(){ $('span[data-field='+$(this).attr('id')+']').text($(this).val()); shoeArray.push ( parseInt($(this).val()) ); }); return shoeArray; } Check this function function

I'm looking to create an associative array in JS, but use constants defined as part of the class as indices. The reason I want this is so that users of the class can use the constants (which define events) to trigger actions. Some code to illustrate: STATE_NORMAL = 0; STATE_NEW_TASK_ADDED = 0; this.curr_state = STATE_NEW_TASK_ADDED; this.state_machine = { /* Prototype: STATE_NAME: { EVENT_NAME: { "next_state": new_state_name, "action": func } } */ STATE_NEW_TASK_ADDED : { // I'd like this to be a constant this.EVENT_NEW_TASK_ADDED_AJAX : { "next_state": STATE_NEW_TASK_ADDED, "action" :

I have a very simple D3 example that first reads data into an associative array, then displays it in a bar graph. I can't seem to get anything to display using this method though. Instead, I have to insert a task in between: Read the data into an associative array, copy that data into a simple array, then display the bar graph using the simple array. chart.selectAll("div") .data(genreAssociative) .enter().append("div") .style("width", function(d) { return d * 10 + "px"; }) .text(function(d) { return d; }); The above does not work. genreSimple = []; for (var genre in genreAssociative)
