html源码如下，我想使用油猴来改变原先openWindow函数由原来的在小窗口打开改为浏览器新标签打开，但是我怎么改都不行，不放在（function(){****}）()也不行，望高手指点指点！

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>测试页</title></title>
<script>
function openWindow(url, width, height) {
    if (width == '') {
        width = screen.width - 20;
    }
    if (height == '') {
        height = screen.height - 120;
    }
    var win = window.open(url, '', 'height=' + height + 'px,width=' + width
        + 'px,resizable=yes,toolbar:0,menubar:0,scrollbars=1');
    return win;
}
</script>
</head>
<body>

<a href="javascript:void(0);" onclick="javascript:openWindow('https://baidu.com','','')">综合办理</a>

</body>
</html>

油猴代码如下：

// ==UserScript==
// @name 广西医疗基层window.open改写
// @namespace 6666666666
// @include  ***************
// @run-at document-idle
// ==/UserScript==

(function(){
 function openWindow(url, width, height) {
    if (width == '') {
        width = screen.width - 20;
    }
    if (height == '') {
        height = screen.height - 120;
    }
    // if (url.indexOf('?') > 0) {
    //     url += "&username=" + cjkEncode(user_username);
    // } else {
    //     url += "?username=" + cjkEncode(user_username);
    // }
    var win = window.open(url);
    return win;
}
})();
