xmlrequest status codes

[dols]

Hello,

below the fragment that works fine, but nevertheless, the value of xmlhttp.status
turns out to be zero (0), and the corresponding value for xmlhttp.statusT ext is "unknown".

Does anyone know the details of ALL the statuscodes when the value for readyState is 4 (= completed).


Also, where could I have found the answer myself???

thanks,

Frens


xmlhttp.open("G ET", "test.txt",true );
xmlhttp.onready statechange=fun ction() {

if (xmlhttp.readyS tate==4) {
window.alert("S how the stuff");}
}
xmlhttp.send(nu ll)

window.alert(xm lhttp.readyStat e);
window.alert(xm lhttp.responset ext);
window.alert(xm lhttp.responseX ML);
window.alert(xm lhttp.status);
window.alert(xm lhttp.statusTex t);

Hello,

anyone know why status code after the GET and SEND is 0?

It should be 200 since the file has been loaded and can be assessed.

thanks,

Frens



<script type="text/javascript">


var xmlhttp;

xmlhttp = new ActiveXObject(" Microsoft.XMLHT TP");

if (xmlhttp) {
document.write( '<p class="example" ><a href="#" onclick="exampl e();return false;">Try the example.</a></p>')
}

function example() {

xmlhttp.open("G ET","just some text.txt",true) ;
xmlhttp.onready statechange=fun ction() {


if (xmlhttp.readyS tate == 4)
if (xmlhttp.status == 200)
alert("Server is done!");
else if (xmlhttp.status == 404)
alert("Request URL does not exist");
else
alert("Error: status code is " + xmlhttp.status) ;

if (xmlhttp.readyS tate==4) {
if (xmlhttp.status ==0) { // !! This should be 200 since all seems right

var local=new Function("retur n "+xmlhttp.respo nseText)();
window.alert(xm lhttp.responseT ext);

window.alert("C ode - Name\n"+local[0].id+' - '+local[0].name);

} else {
alert("not found");
}

} // end statechangefunc tion

} // end example function

xmlhttp.send(nu ll);

}
</script>

Hi,

Your ajax code seems to rely on IE (activeX). Try looking at

http://www-128.ibm.com/developerworks/web/library/wa-ajaxintro1.html

And use the cross-browser Ajax code.

xmlhttp.open("G ET", "test.txt",true );
xmlhttp.onready statechange=fun ction() {

if (xmlhttp.readyS tate==4) {
window.alert("S how the stuff");}
}
xmlhttp.send(nu ll)

window.alert(xm lhttp.readyStat e);
window.alert(xm lhttp.responset ext);
window.alert(xm lhttp.responseX ML);
window.alert(xm lhttp.status);
window.alert(xm lhttp.statusTex t);
