Hi I've the following code in jsp. I am trying to pass the value to javascript as follows. But it is not working.The code is as follows:

    <td><button name = btn onclick=callMe(<c:out value='${bus.vehicleId}'/>)>Show Details</button></td>

(Vehicle id is printing if I use in my jsp.) Javascript is like this.

    function callMe(myId) {

        alert(myId);}

Here I am getting value as undefined. I've tried in different way as follows

    <td><button name = btn onclick=callMe('${bus.vehicleId}')>Show tails</button></td>

This is also not working.Please help me asap.
