Drop in once per session

[JimmerUK]

I'm having real issues solving this one, (although I admit to knowing absolutely nothing about javascript).

I love the drop in style of thefollowing script:


<script language="JavaScript1.2">

// Drop-in content box- By Dynamic Drive
// For full source code and more DHTML scripts, visit http://www.dynamicdrive.com
// This credit MUST stay intact for use

var ie=document.all
var dom=document.getElementById
var ns4=document.layers
var calunits=document.layers? "" : "px"

var bouncelimit=32 //(must be divisible by 8)
var direction="up"

function initbox(){
if (!dom&&!ie&&!ns4)
return
crossobj=(dom)?document.getElementById("dropin").style : ie? document.all.dropin : document.dropin
scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
crossobj.top=scroll_top-250+calunits
crossobj.visibility=(dom||ie)? "visible" : "show"
dropstart=setInterval("dropin()",50)
}

function dropin(){
scroll_top=(ie)? truebody().scrollTop : window.pageYOffset
if (parseInt(crossobj.top)<100+scroll_top)
crossobj.top=parseInt(crossobj.top)+40+calunits
else{
clearInterval(dropstart)
bouncestart=setInterval("bouncein()",50)
}
}

function bouncein(){
crossobj.top=parseInt(crossobj.top)-bouncelimit+calunits
if (bouncelimit<0)
bouncelimit+=8
bouncelimit=bouncelimit*-1
if (bouncelimit==0){
clearInterval(bouncestart)
}
}

function dismissbox(){
if (window.bouncestart) clearInterval(bouncestart)
crossobj.visibility="hidden"
}

function truebody(){
return (document.compatMode!="BackCompat")? document.documentElement : document.body
}


window.onload=initbox

</script>

Problem is, I need it to only display once per session.

I found the followng script that only displays once per session, which is very good but it doesn't bounce in:



<script>

//Post-it only once per browser session? (0=no, 1=yes)
//Specifying 0 will cause postit to display every time page is loaded
var once_per_browser=1

///No need to edit beyond here///

var ns4=document.layers
var ie4=document.all
var ns6=document.getElementById&&!document.all

if (ns4)
crossobj=document.layers.postit
else if (ie4||ns6)
crossobj=ns6? document.getElementById("postit") : document.all.postit


function closeit(){
if (ie4||ns6)
crossobj.style.visibility="hidden"
else if (ns4)
crossobj.visibility="hide"
}

function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) { // if cookie exists
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value
if (end == -1)
end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}

function showornot(){
if (get_cookie('postdisplay')==''){
showit()
document.cookie="postdisplay=yes"
}
}

function showit(){
if (ie4||ns6)
crossobj.style.visibility="visible"
else if (ns4)
crossobj.visibility="show"
}

if (once_per_browser)
showornot()
else
showit()

</script>

<script language="JavaScript1.2">

//drag drop function for ie4+ and NS6////
/////////////////////////////////

function drag_drop(e){
if (ie4&&dragapproved){
crossobj.style.left=tempx+event.clientX-offsetx
crossobj.style.top=tempy+event.clientY-offsety
return false
}
else if (ns6&&dragapproved){
crossobj.style.left=tempx+e.clientX-offsetx
crossobj.style.top=tempy+e.clientY-offsety
return false
}
}

function initializedrag(e){
if (ie4&&event.srcElement.id=="postit"||ns6&&e.target.id=="postit"){
offsetx=ie4? event.clientX : e.clientX
offsety=ie4? event.clientY : e.clientY

tempx=parseInt(crossobj.style.left)
tempy=parseInt(crossobj.style.top)

dragapproved=true
document.onmousemove=drag_drop
}
}
document.onmousedown=initializedrag
document.onmouseup=new Function("dragapproved=false")

</script>

I've tried merging the two scripts, but as I said above, I don't have the first clue about javascript, and what seems an obvious solution doesn't work, so must be wrong.

Does anyone have any clues, or can point me in the right direction?

[JimmerUK]

Surely there must be some javascript wizards out there who can tell me which bit to put where?

[ddadmin]

Actually "drop in once per session" is a built in feature of "Drop In Content" script. Is there a reason why you're not just using the wizard on this page to generate the appropriate code: http://www.dynamicdrive.com/dynamicindex17/dropinbox.htm ?

[JimmerUK]

Ah ha! Perfect. I couldn't find the original page from where I got the script, searching didn't bring it up :( and I copied the code from another site where I used the drop-in box. I was desperate for it as it's a fantastic script.

Cheers for that.

Hi. I have a script which is of the same thing but probably an earlier version.

It allows me to bounce in on an onclick (the later version doesn't seem to let me do this.) The problem is that it won't have the bounce occurring twice without a page reload.

Does anyone know why?



var calunits = "px";
var bouncelimit = 20; // must be divisible by 5
var crossobj;
var timer;

function initbox(id)
{
crossobj = document.getElementById(id).style;
var scroll_top = getPageY();
crossobj.top = (scroll_top - 500) + calunits;
crossobj.display = "";
setTimeout("dropin()",50);
}

function dropin()
{
var scroll_top = getPageY();
if (parseInt(crossobj.top) < 50 + scroll_top)
{
crossobj.top = (parseInt(crossobj.top) + 40) + calunits;
setTimeout("dropin()",50);
}
else
{
timer = setInterval("bouncein()",50);
}
}

function bouncein()
{
crossobj.top = (parseInt(crossobj.top) - bouncelimit) + calunits;
if (bouncelimit < 0)
bouncelimit += 5;
bouncelimit = bouncelimit * -1;
if (bouncelimit == 0)
clearInterval(timer);
}

function getPageY()
{
if (window.pageYOffset)
var scroll_top = window.pageYOffset;
else if (document.documentElement.scrollTop)
var scroll_top = document.documentElement.scrollTop;
else
var scroll_top = document.body.scrollTop;

return scroll_top;
}

Thanks.
