slide out div when scrolling

[toolman]

Hi,

 

Does anyone know where I can find a script that displays a div when you scroll down the page, like this:

- if you scroll down a bit you will see a box slide out.

 

Thanks.

You can do this with javascript. window.pageYOffset is how far the window will need to scroll before your div is going to show.

 

function testScroll(ev){
 if(window.pageYOffset>270){
   document.getElementById("top").className = "show"; //Apply a css class which gives it the property display: inline; (this is the default display)
 }else if(window.pageYOffset<270){
   document.getElementById("top").className = "hide"; //Apply a css class which gives it the property display: none;
 };
}

//Run the above function whenever the window scrolls
window.onscroll=testScroll();

 

Hopefully that'll get your started.

In stead of windows.pageYOffset one would better use document.documentElement.scrollTop || document.body.scrollTop. The first is not supported by IE<9.

Who do you mean with 'our expert PHP developers', this being your first post?? And why refer to PHP developers anyway, if PHP cannot even make something like this??
