I. Scroll up and down
1. displayed content

Code

<Div id = "demo" style = "OVERFLOW: hidden; WIDTH: 200px; HEIGHT: 100px;">
<Table border = "0" cellpadding = "0" cellspacing = "0">
<Tr>
<Td id = "demo1"> <table width = "100%" height = "99" border = "0" cellpadding = "0" cellspacing = "0">
<Tr>
<Td> 1 </td>
</Tr>
<Tr>
<Td> 2 </td>
</Tr>
<Tr>
<Td> 3 </td>
</Tr>
</Table> </td>
</Tr>
<Tr>
<Td id = "demo2"> </td>
</Tr>
</Table>
</Div>

2. Scroll up JS
Code

<SCRIPT>
Var speed = 30
Var MyMarh = setInterval (Marqueeh, speed)
Demo2.innerHTML = demo1.innerHTML
// The principle is to constantly enter demoh1 content in demoh2, and then clear invisible content
// Use a table with two rows and one column. Put another table with content loaded in the previous column, which is defined as demoh1. The next column is an empty TD and is defined as demoh2.
// SPEED is used to control the SPEED.
Demo. onmouseover = function () {clearInterval (MyMarh )}
Demo. onmouseout = function () {MyMarh = setInterval (Marqueeh, speed )}
Function Marqueeh (){
If (demo2.offsetHeight-demo. scrollTop <= 0)
Demo. scrollTop-= demo1.offsetHeight
Else {
Demo. scrollTop ++
}
}
</SCRIPT>

3. Scroll down JS
Code

<Script>
Var speed = 30
Demo2.innerHTML = demo1.innerHTML
Demo. scrollTop = demo. scrollHeight
Var MyMar = setInterval (Marquee, speed)

Demo. onmouseover = function () {clearInterval (MyMar )}
Demo. onmouseout = function () {MyMar = setInterval (Marquee, speed )}
Function Marquee (){
If (demo1.offsetTop-demo. scrollTop> = 0)
Demo. scrollTop + = demo2.offsetHeight
Else {
Demo. scrollTop --
}
}
</Script>

2. Scroll left and right
1. display content
Code

<Div id = "demo" style = "overflow: hidden; height: 100px; width: 200px;">
<Table cellpadding = "0" cellspace = "0" border = "0">
<Tr>
<Td id = "demo1"> <table width = "200" border = "0" cellspacing = "0" cellpadding = "0">
<Tr>
<Td> 1 </td>
<Td> 2 </td>
<Td> 3 </td>
</Tr>
</Table> </td>
<Td id = "demo2"> </td>
</Tr>
</Table>
</Div>

2. scroll to the left of JS
Code

<Script>
Var speed = 30
Var MyMar = setInterval (Marquee, speed)
Demo2.innerHTML = demo1.innerHTML
Demo. onmouseover = function () {clearInterval (MyMar )}
Demo. onmouseout = function () {MyMar = setInterval (Marquee, speed )}
Function Marquee (){
If (demo2.offsetWidth-demo. scrollLeft <= 0)
Demo. scrollLeft-= demo1.offsetWidth
Else {
Demo. scrollLeft ++
}
}
</Script>

3. Scroll JS to the right
Code

<Script>
Var speed = 30
Var MyMar = setInterval (Marquee, speed)
Demo2.innerHTML = demo1.innerHTML
Demo. onmouseover = function () {clearInterval (MyMar )}
Demo. onmouseout = function () {MyMar = setInterval (Marquee, speed )}
Function Marquee (){
If (demo. scrollLeft <= 0)
Demo. scrollLeft + = demo2.offsetWidth
Else {
Demo. scrollLeft --
}
}
</Script>
