Hi.....I am trying to fetch the id from database on click of an image and assigning it to a element and trying to print that id in javascript. When i print it does not gives me error but written output as "undefined".

What I have tried:

This is my PHP Code:

PHP

';
echo "";
while($result=mysql_fetch_array($que))
{

echo " ";
echo  ' ';
 $idee=$result['Id'];

 echo $idee;
 
 echo ''.'<a href=""></a>'.'';
 $count++;
 echo " ";
if($count%3==0)
echo "";
}
echo "";
}
?>

And this is my Javascript code:

JavaScript

function fun()
{
document.write(document.getElementById("show").value);

  
        
alert("welcomee");
}

Your code is very vague but you can try something like this -

HTML

<input type="text" id="show" value="<?PHP echo $idee; ?>" />

function fun()
{
var show = document.getElementById("show").value);

if (show == "") {
    alert("PHP did not load the id");
} else {
    alert(show);  
        
    alert("welcomee");
}
}
