IE error: Automation server can't create object ... when ActiveX disabled

[rbygrave]

If you are using an IE Browser that has ActiveX disabled then jQuery ajax requests will throw a javascript error "Automation server can't create object".

My workaround (for my situation) is to detect this situation with something like...

function isAjaxEnabled() {

try {

var test = new XMLHttpRequest();

// do not need to use ActiveXObject as this has already been assigned to XMLHttpRequest.

return true;

} catch (ex) {

return false;

}

}

Another approach would be to support ajax via an iframe?

This is correct. If ActiveX is disabled, then Ajax requests won't work - and there will be nothing to fall back to. Throwing an exception seems applicable in this instance.
