前段代码:
<div id="out" style=" width:400px;overflow:hidden;"> <div id="int" style="white-space:nowrap;width:800px;"> <asp:Label ID="lblTable" runat="server" Text="Label"></asp:Label> </div> </div> <label onmousedown="marqueeById(‘l‘,‘out‘)" onmouseup="marqueeStop()"><<<<</label> <label onmousedown="marqueeById(‘r‘,‘out‘)" onmouseup="marqueeStop()">>>>></label>
注意:内层div宽度大于外层div,宽度的设定不仅局限于实际像素,也可使用百分比;js指向的的是外层div。外层div内部元素超出部分隐藏overflow:hidden,内层div的text不允许换行white-space:nowrap
后台:
protected void Page_Load(object sender, EventArgs e) { ShowMenu(20); } private void ShowMenu(int m) { string strTable = ""; for (int i = 0; i <= m; i++) { strTable += "<a href=\"# \" class=\"nav\" ><span>" + i + "</span></a>"; } lblTable.Text = strTable; }
注意:自动生成的菜单栏;
JavaScript:
var speed = 10; //数字越大速度越慢 var getId; //需要移动的控件ID var myMark;//开关标记 function marqueeById(direction,id) { getId = document.getElementById(id); direction == "r" ? moveRight() : moveLeft(); } function marqueeStop() { clearInterval(myMark); } function moveRight() { myMark = setInterval(function () { getId.scrollLeft++ }, speed); } function moveLeft() { myMark = setInterval(function () { getId.scrollLeft-- }, speed); }
