I want to generate tooltip based on a dynamically changing background image in css. This is my my_css.php file.
<?php
header('content-type: text/css');
$i = $_GET['index'];
if($i == 0)
$bg_image_path = "../bg_red.jpg";
elseif ($i == 1)
$bg_image_path = "../bg_yellow.jpg";
elseif ($i == 2)
$bg_image_path = "../bg_green.jpg";
elseif ($i == 3)
$bg_image_path = "../bg_blue.jpg";
?>
.tooltip {
white-space: nowrap;
color:green;
font-weight:bold;
border:1px solid black;;
font-size:14px;
background-color: white;
margin: 0;
padding: 7px 4px;
border: 1px solid black;
background-image: url(<?php echo $bg_image_path; ?>);
background-repeat:repeat-x;
font-family: Helvetica,Arial,Sans-Serif;
font-family: Times New Roman,Georgia,Serif;
filter:alpha(opacity=85);
opacity:0.85;
zoom: 1;
}
In order to use this css I added
<link rel="stylesheet" href="css/my_css.php" type="text/css" media="screen" />
in my html <head> tag of javascript code. I am thinking of passing different values of 'index' so that it would generate the background image dynamically. Can anyone tell me how should I pass such values from a javascript ? I am creating the tooltip using
var tooltip = document.createElement("div");
document.getElementById("map").appendChild(tooltip);
tooltip.style.visibility="hidden";
and I think before calling this createElement, I should set background image.
