Webmaster Forum / HTML, CSS, Scripts / JavaScript / November 2007javascript array syntax
hello, is there a way to create an array in this way?: new Array('key1'='value1','key2'='value2','key3'='value3') ?????? thanks, simone, http://www.notte.com > is there a way to create an array in this way?: > > new Array('key1'='value1','key2'='value2','key3'='value3') This type of construction would not be an array anymore (though some call it an associative array). The preferred term in javascript is an object. { key1: 'value1', key2: 'value2', key3: 'value3' } -- Bart Bart Van der Donck said the following on 11/30/2007 6:59 AM: >> is there a way to create an array in this way?: >> [quoted text clipped - 5 lines] > > { key1: 'value1', key2: 'value2', key3: 'value3' } What you created is an Object, and I am not sure that is what the OP was asking about. It reads as if it is being asked for a shortcut method to doing this: var myArray = new Array() myArray['key1'] = 'value1'; myArray['key2'] = 'value2'; myArray['key3'] = 'value3'; myArray is still an Array, it is just overkill when a plain Object would suffice. Even then, it is still an "Object", just an extended Object with Array properties.

The moment any programmers gets the *difference* between an Object and an Array is the moment one stops perling/phping around and starts programming.

Google Groups knows that so far you never got any difference between anything here (and the prospects for a change of that are equally bad), so that point really is moot.

Listen: you learn the basics of OOP or stop posting.

But `key1', `key2' and `key3' are _not_ properties that are *inherited* from another (built-in) object, and newly created object is _not_ a *built-in* object. That is the distinction you fail to make here. > Listen: you learn the basics of OOP or stop posting. It's getting > annoying. ROTFL PointedEars SignatureAnyone who slaps a 'this page is best viewed with Browser X' label on a Web page appears to be yearning for the bad old days, before the Web, when you had very little chance of reading a document written on another computer, another word processor, or another network. -- Tim Berners-Lee VK said the following on 11/30/2007 10:15 AM: >> Bart Van der Donck said the following on 11/30/2007 6:59 AM: >> [quoted text clipped - 18 lines] > > Date is also an extended Object with extra properties. I would ask you what you think that has to do with what I wrote, but I don't think I want to entertain the wild thought processes you have at times. > The moment any programmers gets the *difference* between an Object > and an Array is the moment one stops perling/phping around and > starts programming. Your village misses you badly. > Don't tell me you didn't reach this state, please. I will be completely relieved if, by your reasoning, if you would at least try to attain the status of "perling/phping around" and leave JS alone until after that time. Then maybe you can "start programming". Until then, your village misses you badly.

JS doesn't know associative arrays. As Bart said - use an object instead.
