Question

I write my scripts in PHP, and there are HTML and javascripts inside. What I want is when I click a button(in HTML), it calls a javascript function, the function should visit a url like “http://localhost/1/2” And the page stays as before. Is it feasible?

I just want it work, no matter in js or php. Thanks.

Since the page is on the same domain, you may use an Ajax request:

var request = new XMLHttpRequest();
request.open("GET", url, true);
request.send(null);

Note that this does not do any error-checking, however. If you need that, there are a multitude of available tutorials easily found with a search.

And since you ask, for pages not on the same domain, using an <iframe> is sometimes possible:

var frame = document.createElement("iframe");
frame.src = url;
frame.style.position = "relative";
frame.style.left = "-9999px";
document.body.appendChild(frame);
