您可以使用内置的javascript setInterval。

var ajax_call = function() {
  //your jQuery ajax code
};

var interval = 1000 * 60 * X; // where X is your every X minutes

setInterval(ajax_call, interval);

或者如果您是更简洁的类型…

setInterval(function() {
  //your jQuery ajax code
}, 1000 * 60 * X); // where X is your every X minutes
