Question

I am having trouble accessing a Javascript function from my code behind file. I need to do this as I am using the GoogleMaps JS API to add markers to a map based on addresses retrieved from my database. I have a function called AddMarker that takes in the address as a parameter, so I need to be able to call that from my code behind file in the page_load function.

To simplify the question, how I can I call this javascript function to display an alert with a string passed from my code behind file?:

function hello(message)
{
alert(message)
}

Thanks in advance!

P.S Either vb or c# will do 🙂

You may consider this a hack but you could always put your message in an html element like:

<p id='message' style='display: none;'>Your Message</p>

Then in your javascript:

function hello()
{
    var m = document.getElementById('message').innerHTML;
    alert(m);
}
