Associative arrays in Javascript?
Is it possible to do in javascript something like this:
array('one' => 'value-1','two'=> 'value-2');
And after that access it like this $var['one'] and to return value-1 I'm kinda new to JS, and google didn't gave me a good answer.
Yes and no - you can create an object like this:
var theObject = { one: "value 1", two: "value 2" };
but it's not an array. True arrays in JavaScript have strictly numeric indexes. (You can add string-named properties to a JavaScript array object, but they're not accounted for in the .length of the array.)
edit — to add properties to the object (or any object), you can use the . or [] operators:
theObject.newProperty = "something new";
theObject[ computeNewPropertyName() ] = "wow";
The second example shows the [] operator, which is used when the name of a property is computed dynamically some how (in the example, by a function call, but it could be any expression).
theObject.five = '5' or theObject['five'] = '5'.
Yep, it's called an object:
var your_object = {
'one': 'value-1',
'two': 'value-2'
};
hah))) in normal languages this is called a dictionary))) In javascript you can create dictionary or object like this
a = {"one":"value-1", "two":"value-2"}
a["one"] returns "value-1"
Try
Array (an ordered, indexed set of items) :
var myArray = [
'value-1',
'value-2'
];
Object (an orderless set of keyed properties):
var myObject = {
'one': 'value-1',
'two': 'value-2'
};
