（节点）js中的“关联数组”数组

Question

I have this code in php to translate in js (node to be precise)

$config['test'] = array(
     "something" => "http://something.com/web/stats_data2.php"
    ,"somethingelse" =>"http://somethingelse.com/web/stats_data2.php"
    ,"anothersomething" =>"http://anothersomething.com/web/stats_data2.php"
);

So I started to write this:

config.test = [
      something = 'http://something.com/web/stats_data2.php'
    , somethingelse = 'http://somethingelse.com/web/stats_data2.php'
    , anothersomething = 'http://anothersomething.com/web/stats_data2.php']

But I m not sure if it s not supposed to be writed like this instead:

config.test.something = 'http://something.com/web/stats_data2.php';
config.test.something = 'http://somethingelse.com/web/stats_data2.php';
config.test.anothersomething = 'http://anothersomething.com/web/stats_data2.php';

The goal is, if I do console.log(config.test.['something']);, to have the link in the output.

Is there any way to test it without server (since I don t have any before tomorrow), or is my syntax good?

Javascript does not have associative arrays, only plain objects:

var myObj = {
    myProp: 'test',
    mySecondProp: 'tester'
};

alert(myObj['myProp']); // alerts 'test'

myObj.myThirdProp = 'testing'; // still works

for (var i in myObj) {
    if (!myObj.hasOwnProperty(i)) continue; // safety!
    alert(myObj[i]);
}
// will alert all 3 the props

For converting PHP arrays to javascript use json_encode

If you want to play it safe though, you would want to quote the properties as well, as reserved keywords will make your construct fail in some browsers, or will not be accepted by some compression systems:

var obj1 = {
    function: 'boss',       // unsafe
    'function': 'employee'  // safe
};

console.log(obj1.function);    // unsafe
console.log(obj1['function']); // safe
