There's an entire practice that says it's a bad idea to have inline functions/styles. Taking into account you already have an ID for your button, consider

JS

var myvar=15;
function init(){
    document.getElementById('EditBanner').onclick=function(){EditBanner(myvar);};
}
window.onload=init;

HTML

<input id="EditBanner" type="button"  value="Edit Image" />

<script>var myVar = 15;</script>
<input id="EditBanner" type="button" value="Edit Image" onclick="EditBanner(myVar);"/>

Yes, JavaScript variables will exist in the scope they are created.

var bannerID = 55;

<input id="EditBanner" type="button" 
  value="Edit Image" onclick="EditBanner(bannerID);"/>


function EditBanner(id) {
   //Do something with id
}

If you use event handlers and jQuery it is simple also

$("#EditBanner").click(function() {
   EditBanner(bannerID);
});
