Iam new to ajax. while trying out some sample programs with php, i get an javascript error 'Unknown Runtime Error'. what am i really missing out. Let me paste my code so u can understand better.
<html>
<head>
<script src="clienthint.js"></script>
</head><body><form>
First Name:
<input type="text" id="txt1" onkeyup="showHint(this.value)">
</form><p>Suggestions: <span id="txtHint"></span></p> </body>
</html>
clienthint.js:
var xmlHttp
function showHint(str)
{
if (str.length==0)
{
document.getElementById("txtHint").innerHTML=""
return
}
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}
var url="test.tacticalOverview.php"
//url=url+"?q="+str
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}
function stateChanged()
{
if (xmlHttp.readyState==4 ¦¦ xmlHttp.readyState=="complete")
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText
}
}
function GetXmlHttpObject()
{
var objXMLHttp=null
if (window.XMLHttpRequest)
{
objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject)
{
objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}
Any help is greatly appreciated!
Thanks.
