是否有一个只刷新PHP脚本的jQuery函数？

Question

I'm new to AJAX, jQuery, etc.

But is there a function that will just auto-refresh a PHP script?

Answer 1

If you wanted to execute a javascript function at regular intervals you cold use the window.setInterval function:

window.setInterval(function() {
    // this method will execute on every 5 seconds
}, 5000);

So you could write a function that will send an AJAX request to your PHP script:

window.setInterval(function() {
    // replace the contents of an element with id="res" 
    // every 5 seconds by the result of the PHP script
    $('#res').load('/foo.php');
}, 5000);

Or if you want to reload the entire page (without using AJAX) you could use window.location.reload();

Answer 2

You don't need jQuery, just plain old Javascript.

window.location.reload()

should reload the current page. Combine with window.setTimeout to do it after some delay if that's what you need.

See docs for:

• window.location
• window.setTimeout
