适用于IE的自适应大小并且自动居中的对话框页面(javaScript)

IE下有效

function AutoSizeWindow() {
    if (window.dialogArguments == null) {
        return; //忽略非模态窗口
     }

    var _offset = new Object();
    _offset.height = 40;
    _offset.width = 40;
    _offset.top = -40;
    _offset.left = 0;
    _offset.minHeight = 400;
    _offset.minWidth = 400;

    var _myDialog = new Object();
    _myDialog.height = document.body.scrollHeight + _offset.height;
    _myDialog.width = document.body.scrollWidth + _offset.width;
    _myDialog.top = (this.screen.height - _myDialog.height) / 2 + _offset.top;
    _myDialog.left = (this.screen.width - _myDialog.width) / 2 + _offset.left;

    if (_myDialog.height < _offset.minHeight) _myDialog.height = _offset.minHeight;
    if (_myDialog.width < _offset.minWidth) _myDialog.width = _offset.minWidth;

    window.dialogHeight = _myDialog.height + "px";
    window.dialogWidth = _myDialog.width + "px";
    window.dialogTop = _myDialog.top + "px";
    window.dialogLeft = _myDialog.left + "px";
}
