A new simple way to make a image slider- Javascript Code
Hi all!
I found that is difficult to search a simple javascript code about scrolling image slide. You can find them on Internet but they often are long and complex or hidden from us to prevent edit.
I just found a simple way to resolve this. I hope it will help your editting easier to make it yours!
We need 2 div tag to make a slide. ChildDiv to store image array and ParentDiv to contain Child Div.
Note:
Image Array's Structure: [<Image's Link>, <Image's Width>, <URL to Go>]
Functions:
DoSlide(), Make Slide to run.
setmouse(param), set Slide play and pause when pointer over or out on images;
Dr_ImgArr(); Print image array to HTML;
getE(), getElementById();
DivWidth: Width of ParentDiv;
MoreImage: Num Of Image on a begin of Image Array, insert into the last of ChildDiv to continue the Slide;
....
If you have anymore comment, please reply here so that I can make it more perfect,
thank for all.

Style
Code:
<style>
#ParentDiv
{
margin: auto;
width: 600px;
overflow: hidden;
}
#ChildDiv
{
width: 6000px;
position:relative;
cursor:pointer;
}
#ParentDiv img
{
float: left;
padding: 3px;
margin: 0px;
}
</style>
