遍历一个javascript数组

Question

I have a javascript array with this structure :

array('123455'=>'kjqs dkjq sdkj ','135468'=>'msldmsdlv sdml,sdmlcsdc ','16554d'=>'msljkfhsdlkjfhsmdlkfh')

I would like to loop through it without exceeding the limits , and how can I get the index and value

thanks

Answer 1

Same as Emmerman but don't forget the var keyword to avoid creating global variables! And add the check for own property to omit properties from prototypes.

var array = {
  '123455': 'kjqs dkjq sdkj ',
  '135468': 'msldmsdlv sdml,sdmlcsdc ',
  '16554d': 'msljkfhsdlkjfhsmdlkfh'
};

for (var key in array) {
  if (array.hasOwnProperty(key)) {
    console.log(key, array[key]);
  }
}

Besides this I think you're in the wrong language. I think it's done like this in php:

$array = array(
  '123455' => 'kjqs dkjq sdkj ',
  '135468' => 'msldmsdlv sdml,sdmlcsdc ',
  '16554d' => 'msljkfhsdlkjfhsmdlkfh'
);

foreach ($array as $key => $value) {
  echo "\$array[$key] => $value.\n";
}

Answer 2

for (key in array) {
  console.log(key+' - '+array[key]);
}
