You can use the built-in javascript setInterval.
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);
or if you are the more terse type ...
或者如果你是更简洁的类型......
setInterval(function() {
//your jQuery ajax code
}, 1000 * 60 * X); // where X is your every X minutes

A bit late but I used jQuery ajax method. But I did not want to send a request every second if I haven't got the response back from the last request, so I did this.
有点晚了，但我使用了 jQuery ajax 方法。但是如果我没有从上次请求中得到响应，我不想每秒发送一个请求，所以我这样做了。
function request(){
if(response == true){
// This makes it unable to send a new request
// unless you get response from last request
response = false;
var req = $.ajax({
type:"post",
url:"request-handler.php",
data:{data:"Hello World"}
});
req.done(function(){
console.log("Request successful!");
// This makes it able to send new request on the next interval
response = true;
});
}
setTimeout(request(),1000);
}
request();

No plugin required. You can use only jquery.
不需要插件。您只能使用 jquery。
If you want to set something on a timer, you can use JavaScript's setTimeoutor setIntervalmethods:
如果你想在计时器上设置一些东西，你可以使用 JavaScript 的setTimeout或setInterval方法：
setTimeout ( expression, timeout );
setInterval ( expression, interval );

你可以setInterval()在javascript中使用
<script>

setInterval("yourAjaxCall()",1000);
function yourAjaxCall(){...}
</script>

你有几个选择，你可以setTimeout()或setInterval()。 这是一篇很好的文章，详细说明了如何使用它们。
The magic is that they're built in to JavaScript, you can use them with any library.
神奇之处在于它们内置于 JavaScript，您可以将它们与任何库一起使用。
