Try this: In your javascript code:

window.onload = initPage;
function initPage() {
  document.getElementById("cmbissueid").onBlur = showSupplier(document.getElementById("cmbissueid").value);
}

 

Then remove:

onchange="showSupplier(this.value);"

 

from the html code

 

Hope that helps,

Does the browser give you an alertbox?
