[JavaScript]公告DIV實現

公告視窗如果用彈出式視窗的話，有可能會被些什麼上網助手給屏蔽了！所以寫了個公告DIV的JS。

代碼如下：（放入到Body地區即可）

        <div id="affiche" ondblclick="closeDiv();" style="BORDER-RIGHT: black 1px outset; BORDER-TOP: black 1px outset; BORDER-LEFT: black 1px outset; WIDTH: 30%; CLIP: rect(auto auto auto auto); BORDER-BOTTOM: black 1px outset; POSITION: absolute; HEIGHT: 30%; BACKGROUND-COLOR: whitesmoke; TEXT-ALIGN: center;"align="center">

            <table height="100%" width="100%">

                <tr>

                    <td vAlign="middle" align="center" height="100%">

                                此處為公告內容

                            <div id="timeout"></div>

                    </td>

                </tr>

            </table>

        </div>

            <script language="javascript">

        

            var intOut=10;

            TimeDiv();

            

            function closeDiv()

            {

                document.getElementById("affiche").style.display = "none";

            }

            

            function TimeDiv()

            {

                --intOut;

                if ( intOut>1 )

                {

                    window.setTimeout( "TimeDiv()",1000 );

                    document.getElementById("timeout").innerText=intOut + "秒後/雙擊視窗自動關閉！";

                }

                else

                {

                    closeDiv();

                }

            }

            

            var objDiv = document.getElementById("affiche");

            SetDiv();

            

            function SetDiv()

            { 

                objDiv.style.top = (document.body.offsetHeight - objDiv.offsetHeight)/2 + document.body.scrollTop;

                objDiv.style.left = (document.body.offsetWidth - objDiv.offsetWidth)/2; 

                   if ( intOut>1 )

                {

                    window.setTimeout( "SetDiv()",200 );

                }

            }

            

            </script>
