創(chuàng)建實例:
//參數(shù)直接賦值法
new Marquee("marquee")
new Marquee("marquee","top")
......
new Marquee("marquee",0,1,760,52)
new Marquee("marquee","top",1,760,52,50,5000)
......
new Marquee("marquee",0,1,760,104,50,5000,3000,52)
new Marquee("marquee",null,null,760,104,null,5000,null,-1)
//參數(shù)動態(tài)賦值法
var marquee1 = new Marquee("marquee") *此參數(shù)必選
marquee1.Direction = "top"; 或者 marquee1.Direction = 0;
marquee1.Step = 1;
marquee1.Width = 760;
marquee1.Height = 52;
marquee1.Timer = 50;
marquee1.DelayTime = 5000;
marquee1.WaitTime = 3000;
marquee1.ScrollStep = 52;
marquee1.Start();
參數(shù)說明:
ID "marquee" 容器ID (必選)
Direction (0) 滾動方向 (可選,默認為0向上滾動) 可設置的值包括:0,1,2,3,"top","bottom","left","right" (0向上 1向下 2向左 3向右)
Step (1) 滾動的步長 (可選,默認值為2,數(shù)值越大,滾動越快)
Width (760) 容器可視寬度 (可選,默認值為容器初始設置的寬度)
Height (52) 容器可視高度 (可選,默認值為容器初始設置的高度)
Timer (50) 定時器 (可選,默認值為30,數(shù)值越小,滾動的速度越快,1000=1秒,建議不小于20)
DelayTime (5000) 間歇停頓延遲時間(可選,默認為0不停頓,1000=1秒)
WaitTime (3000) 開始時的等待時間(可選,默認或0為不等待,1000=1秒)
ScrollStep (52) 間歇滾動間距 (可選,默認為翻屏寬/高度,該數(shù)值與延遲均為0則為鼠標懸??刂?-1禁止鼠標控制)
使用建議:
1、建議直接賦予容器的顯示區(qū)域的寬度和高度,如(<div id="marquee" style="width:760px;height:52px;">......</div>)
2、建議為容器添加樣式overflow = auto,如(<div id="marquee" style="width:760px;height:52px;overflow:auto;">......</div>)
3、為了更準確的獲取滾動區(qū)域的寬度和高度,請盡可能將各滾動單位直接賦予正確寬高度
4、對于TABLE標記的橫向滾動,需要對TABLE添加樣式display = inline,如(<div id="marquee" style="width:760px;height:52px;overflow:auto;"><table style="display:inline">......</table></div>)
5、對于翻屏滾動或間歇滾動,要注意各滾動單位間的間距,同時需要對容器的可視高度和可視寬度做好準確的設置,對于各滾動單位間的間距可以通過設置行間距或者單元格的高寬度來進行調(diào)整
6、對于LI自動換行的問題暫時沒有更好的解決辦法,建議將其轉(zhuǎn)換成表格(TABLE)的形式來達到同等的效果
7、針對橫向滾動的文字段落,如果最末端是以空格" "結(jié)束的,請將空格" "轉(zhuǎn)換成" "
8、鼠標懸停滾動思想源自Flash,所以有一定的局限性(容器內(nèi)僅允許用圖片<img>或者帶鏈接的圖片<a><img></a>的形式,并需要禁止其自動換行)
