此问题已在早些时候得到解答,并在此处结束: Open link in Popup Window with Javascript
但如果你向下滚动,你会看到这个评论:
只是注意,我正在使用这种方法,如果您不允许浏览器弹出窗口,则工作正常,但是,如果您这样做,它将打开弹出窗口两次。我通过添加event.preventDefault()解决了这个问题。单击链接,并从windowpop()的开头删除返回。 - madaaah Oct 18' 13 at 18:13
我有两次弹出的同样问题,并且不明白如何使用event.preventDefault();
function windowpop(url, width, height) {
var leftPosition, topPosition;
//Allow for borders.
leftPosition = (window.screen.width / 2) - ((width / 2) + 10);
//Allow for title and status bars.
topPosition = (window.screen.height / 2) - ((height / 2) + 50);
//Open the window.
window.open(url, "Window2", "status=no,height=" + height + ",width=" + width + ",resizable=yes,left=" + leftPosition + ",top=" + topPosition + ",screenX=" + leftPosition + ",screenY=" + topPosition + ",toolbar=no,menubar=no,scrollbars=no,location=no,directories=no");
}
