Now, for example we have to schedule job from any page, where we have to give the time interval using cron.Here Cron is driven by a crontab (cron table) file, a configuration file that specifies shell commands to run periodically on a given schedule. The crontab files are stored where the lists of jobs and other instructions to the cron daemon are kept.The initial option allows you the set the initial cron value.

//Initialize a cron object var cron_field = $('#selector').cron(); //Updating the value of an existing cron object cron_field.cron("value", "12 23 * * *"); //calling the method with the extra argument returns the current value var current_value = cron_field.cron("value")

Above is value method in which we can set the value for cron field.You can set a callback function using the onChange option. The function will be called each time the value changes. For instance, the example in the introduction is implemented as using:

$('#selector').cron({ initial: "42 3 * * 5", onChange: function() { $('#selector-val').text($(this).cron("value")); } });
