in the $.each loop is there a way to set i not to e greater than a number.

$.each(data.forecast.simpleforecast.forecastday, function(i, forecastday){
            forecastHTML += '<li class="grid-seventh-day">';

        });//each loop
        forecastHTML += '</ul>';
      $('#weather').html(forecastHTML);

is it possible to set i here not to be greater than 7 so I only display 7 days of data

Hi Nathon,

You could call the slice method on the forecastday array to get it down to 7 elements. Then $.each would only iterate over those 7 elements.

Something like data.forecast.simpleforecast.forecastday.slice(0, 7) if you wanted the first 7 elements.

A simplified example to illustrate:

var days = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

$.each(days.slice(0, 7), function(i, forecastday){
  console.log(forecastday); // logs 1 2 3 4 5 6 7
});//each loop

I could be wrong. I believe the $.each() iterates internally, so you don't necessarily have direct control of it. You just get access to the current index for each iteration. From what I can figure, you just test if the index reaches 7 within the callback function and return false if it does.
