Issue with displaying two-dimensional array properly on console

I am currently troubleshooting the following code:

var spacetime = [];
spacetime.push({
    Title : [], 
    Space : [],
    Time : []
});

  if (doSelect('Location').length > 0 && doSelect('Date').length > 0) {
   for(var i = 0; i < dateText.length; i++) {
      d += dateText[i] + ' ';
    }
    if(location.match(regex)) {
      spacetime[0].Title.push("Hello");
      spacetime[2].Time.push(d);
      });
    }
  };

However, when I check the console, I receive the error message:

Cannot read property 'Time' of undefined

Interestingly, d is being output correctly despite this error.

Answer №1

When you added an object to the spacetime array, you only made it available at index 0. Make sure to access it using [0] instead of [2] when setting the Time property:

var spacetime = [];
spacetime.push({
    Title : [], 
    Space : [],
    Time : []
});

if (doSelect('Location').length > 0 && doSelect('Date').length > 0) {
   for(var i = 0; i < dateText.length; i++) {
      d += dateText[i] + ' ';
    }
    if(location.match(regex)) {
      spacetime[0].Title.push("Hello");
      spacetime[0].Time.push(d);
    }
};
