You can simply do:
var multiDimensionalArray = eval('[[1,"myName"],[2,"myOtherName"]]');

However, consider using the more secure JSON methods (see below);

--Ken Snyder

  Parse a JSON text, producing a JavaScript value.
  It returns false if there is a syntax error.
var JSON = {};
JSON.decode: function (text) {
  try {
    return !(/[^,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]/.test(
      text.replace(/"(\\.|[^"\\])*"/g, ''))) &&
      eval('(' + text + ')');
    } catch (e) {
      return false;
