IE浏览器弹出窗口

//弹出一个对话框 参数的顺序: url, iWidth, iHeight, vArguments
function openDialog() {
    var url, len = arguments.length, sFeatures, ret;
    if (len == 1) {
        url = arguments[0];
        var iWidth = 800; //弹出窗口的宽度;
        var iHeight = 600;  //弹出窗口的高度;
        return window.showModalDialog(url, "", "dialogWidth=" + iWidth + "px;dialogHeight=" + iHeight + "px;status=no;");
    }
    else {
        url = arguments[0];
        iWidth = arguments[1];
        iHeight = arguments[2];
        sFeatures = "dialogWidth=" + iWidth + "px;dialogHeight=" + iHeight + "px;status=no;";
        if (len == 3) ret = window.showModalDialog(url, "", sFeatures);
        else if (len == 4) ret = window.showModalDialog(url, arguments[3], sFeatures);
        return ret;
    }
}
//弹出一个新窗口 isres:是否可调整大小
function windowOpen(url, iWidth, iHeight, isres) {
    var iTop = (window.screen.availHeight - 30 - iHeight) / 2; //获得窗口的垂直位置;
    var iLeft = (window.screen.availWidth - 10 - iWidth) / 2;  //获得窗口的水平位置;
    var rs;
    if (isres == undefined) rs = 'no';
    else rs = 'yes';
    window.open(url, "_blank", 'height=' + iHeight + ',width=' + iWidth + ',top=' + iTop + ',left=' + iLeft +
        ',toolbar=no,menubar=no,scrollbars=no,resizable=' + rs + ',location=no,status=no ');
}

用法

openDialog('/test/test3.aspx?r=' + Math.random(), 1200, 600, window);//打开对话框
windowOpen('/test/test3.aspx?r=' + Math.random(), 1200, 600);//打开新窗口

openDialog()这种方法已经不适用了，多数浏览器已经不支持，只有IE模式下支持
