平時(shí)在應(yīng)用ajax完成一些操作后總會(huì)使用alert來(lái)給用戶返回一些提示信息。但是介于alert的樣式過(guò)于單調(diào)。所以有時(shí)候需要自己寫一個(gè)類似的提示框來(lái)稍微的美化一下。

那天從網(wǎng)上找了一個(gè)現(xiàn)成的提示框。不過(guò)那個(gè)提示框還是有一些缺陷的，在出現(xiàn)瀏覽器測(cè)滾輪情況下和在IE與FF之間的兼容問(wèn)題。自己修改了一下現(xiàn)在能夠正常的在兩個(gè)瀏覽器上使用。

 

以下是代碼：

 

 

//提交完畢后彈出提示信息并自動(dòng)關(guān)閉

    var msgw,msgh,bordercolor;
    msgw=350;//提示窗口的寬度

    var sWidth,sHeight;
    //獲取當(dāng)前窗口尺寸
    sWidth = document.body.offsetWidth;
    sHeight = document.body.scrollHeight;

    //1.5秒鐘后窗口自動(dòng)關(guān)閉
    window.setTimeout("closewin()",1500);
}

function closewin() {
