Question

I am using this code to get data from json.

$.each(data.id, function(index, value){

output += '<li>'+value.title+'</li>';

}

$('#listview').html(output).listview('refresh');

Sometimes there are no records to display.

How can I know if there are no records and display an alert example: alert(‘No records’); ?

Answer 1

I am assuming that the data.id is an array, since you used$.each on it:

if (data.id.length == 0) {
  // no data
}
