Ans. Supposed to be Yes, you should use ajax here, as you are getting database values asynchronously that on this input what are the according values you are getting without refreshing the whole page.
function getXmlHttpReq(){
if (window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp=new ActiveXObject(\"Microsoft.XMLHTTP\");
}
return xmlhttp;
}
function ajaxCall(){
var xmlhttp = getXmlHttpReq();
xmlhttp.open(\"GET\", \"getData\", true );
xmlhttp.setRequestHeader(\"Content-type\",\"application/x-www-form-urlencoded\");
xmlhttp.send(null);
}
function getXmlHttpReq(){
if (window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp=new ActiveXObject(\"Microsoft.XMLHTTP\");
}
return xmlhttp;
}
function ajaxCall(){
var xmlhttp = getXmlHttpReq();
xmlhttp.open(\"GET\", \"getData\", true );
xmlhttp.setRequestHeader(\"Content-type\",\"application/x-www-form-urlencoded\");
xmlhttp.send(null);
}
