The following code can only pop up a new window every time.

$('a').click(function(){    window.open(this.href, "");    return false;});

var x;$('a').click(function(){    if(x){        x.location.href = this.href;    } else {        x = window.open(this.href, '');    }    return false;});

Press F12 now to execute the code and click the link to try.

Update: If the pop-up window is closed, open it again

var x;$('a').click(function() {    if (!x || x.closed || !x.opener) {        x = window.open(this.href, '');    } else {        x.location.href = this.href;    }    return false;});

Why js? In this way, many browsers will block it by default.It is opened in the current window by default.
Code:

$ ('A '). click (function () {location. href = this. href; // You can move back to the current page // or location. replace (this. href) // cannot roll back to the current page. return false ;});
