问题描述

我的 javascript 经验非常有限.我想在屏幕中央打开新窗口.

My experience with javascript is extraordinarily limited. I would like to have the new window open up in the center of the screen.

<script type="text/javascript">
function fbs_click() {
var twtTitle = document.title;
var twtUrl = location.href;
var maxLength = 140 - (twtUrl.length + 1);
if (twtTitle.length > maxLength) {
    twtTitle = twtTitle.substr(0, (maxLength - 3)) + '...';
}
var twtLink = 'http://twitter.com/home?status=' + encodeURIComponent(twtTitle + ' ' + twtUrl);
window.open(twtLink,'','width=300,height=300'); } </script>

如果有人可以请更新我的代码以完成一个居中的弹出窗口，那将是惊人的！

If somebody can please update my code to accomplish a popup window which is centered that would be amazing!

推荐答案

怎么样(改编自这里):

function MyPopUpWin(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");
}

通过将代码中的 window.open(twtLink,'','width=300,height=300'); 替换为 MyPopUpWin(twtLink, 300, 300); 来调用它

Call it by replacing window.open(twtLink,'','width=300,height=300'); in your code with MyPopUpWin(twtLink, 300, 300);
