Passing Php Variable To Javascript Function

[Nothadoth]

Hey guys, im not very good with javascript so I used a script from DynamicDrive.com to give me a tooltip on mouse over for a div. It works fine, except for if I want to use a php variable as the tooltip text. Why? Here is the javascript code:

---

var offsetfromcursorX=22 //Customize x offset of tooltip

var offsetfromcursorY=20 //Customize y offset of tooltip

var offsetdivfrompointerX=10 //Customize x offset of tooltip DIV relative to pointer image

var offsetdivfrompointerY=14 //Customize y offset of tooltip DIV relative to pointer image. Tip: Set it to (height_of_pointer_image-1).

document.write('<div id="dhtmltooltip"></div>') //write out tooltip DIV

document.write('<img id="dhtmlpointer" src="images/tooltiparrow.gif">') //write out pointer image

var ie=document.all

var ns6=document.getElementById && !document.all

var enabletip=false

if (ie||ns6)

var tipobj=document.all? document.all["dhtmltooltip"] : document.getElementById? document.getElementById("dhtmltooltip") : ""

var pointerobj=document.all? document.all["dhtmlpointer"] : document.getElementById? document.getElementById("dhtmlpointer") : ""

function ietruebody(){

return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body

}

function ddrivetip(thetext, thewidth, thecolor){

if (ns6||ie){

if (typeof thewidth!="undefined") tipobj.style.width=thewidth+"px"

if (typeof thecolor!="undefined" && thecolor!="") tipobj.style.backgroundColor=thecolor

tipobj.innerHTML=thetext

enabletip=true

return false

}

}

function positiontip(e){

if (enabletip){

var nondefaultpos=false

var curX=(ns6)?e.pageX : event.clientX+ietruebody().scrollLeft;

var curY=(ns6)?e.pageY : event.clientY+ietruebody().scrollTop;

//Find out how close the mouse is to the corner of the window

var winwidth=ie&&!window.opera? ietruebody().clientWidth : window.innerWidth-20

var winheight=ie&&!window.opera? ietruebody().clientHeight : window.innerHeight-20

var rightedge=ie&&!window.opera? winwidth-event.clientX-offsetfromcursorX : winwidth-e.clientX-offsetfromcursorX

var bottomedge=ie&&!window.opera? winheight-event.clientY-offsetfromcursorY : winheight-e.clientY-offsetfromcursorY

var leftedge=(offsetfromcursorX<0)? offsetfromcursorX*(-1) : -1000

//if the horizontal distance isn't enough to accomodate the width of the context menu

if (rightedge<tipobj.offsetWidth){

//move the horizontal position of the menu to the left by it's width

tipobj.style.left=curX-tipobj.offsetWidth+"px"

nondefaultpos=true

}

else if (curX<leftedge)

tipobj.style.left="5px"

else{

//position the horizontal position of the menu where the mouse is positioned

tipobj.style.left=curX+offsetfromcursorX-offsetdivfrompointerX+"px"

pointerobj.style.left=curX+offsetfromcursorX+"px"

}

//same concept with the vertical position

if (bottomedge<tipobj.offsetHeight){

tipobj.style.top=curY-tipobj.offsetHeight-offsetfromcursorY+"px"

nondefaultpos=true

}

else{

tipobj.style.top=curY+offsetfromcursorY+offsetdivfrompointerY+"px"

pointerobj.style.top=curY+offsetfromcursorY+"px"

}

tipobj.style.visibility="visible"

if (!nondefaultpos)

pointerobj.style.visibility="visible"

else

pointerobj.style.visibility="hidden"

}

}

function hideddrivetip(){

if (ns6||ie){

enabletip=false

tipobj.style.visibility="hidden"

pointerobj.style.visibility="hidden"

tipobj.style.left="-1000px"

tipobj.style.backgroundColor=''

tipobj.style.width=''

}

}

document.onmousemove=positiontip

---

Here is the code on my php page

---

echo "<div onmouseover=\"ddrivetip('Test Description', 300)\"

onmouseout=\"hideddrivetip()\"><img src=\"$thumbnail\" alt=\"$pd_name\"></div>

";

---

If I swap "Test Description" with $pd_name or anything else the tooltip does not show up at all. Why not? PS. Sorry about the post! I cannot seam to start a new line on this text editor????? The enter key does nothing. Problem with ie10??

why not try using jquery to do what you need, i use a very good plugin called tipsy:

does exactly what you need it to do

Thanks very much i'll take a look at that. Also, I found that my problem was that the variable I was trying to use contained a speech mark, so I fixed it by using str_replace. Anyway, the jquery looks much tidier thanks.

Pass php variable in qoutes '<?php echo $var?>'
