Returning values out of for loop in javascript

rated 0 times [ 82] [ 5] / answers: 1 / hits: 67730 / 13 Years ago, tue, november 15, 2011, 12:00:00

I have the following function:

  function getId(a){

    var aL = a.length;

    for(i = 0; i < aL; i++ ){

      return a[i][2].split(:, 1)[0];

    }    

  }

and when using console.log() within the function instead of return I get all of the values in the loop, and the same goes for document.write. How can I access these values as a string for use in another section of my code?

Thank you in advance.

You can do that with yield in newer versions of js, but that's out of question. Here's what you can do:

function getId(a){

  var aL = a.length;

  var values = [];

  for(i = 0; i < aL; i++ ){

    values.push(a[i][2].split(:, 1)[0]);

  }    

  return values.join('');

}
