Thanks.
After look into the getScript code, I tried to play around with the
readyState of the script elements.
script.onload = script.onreadystatechange = function(){
try{
document.body.innerHTML += "<p>" + this.readyState +
"</p>";
if (!this.readyState || this.readyState == "loaded"
|| this.readyState == "complete"){
document.body.innerHTML += "<p>Success</p>";
head.removeChild( script );
}
}catch(e){
alert("any error " + e);
}
};
1. http://urldoesnotexist.com/fdil.js
This is a request where the browser should not be able to resolve the
server.
Firefox prints nothing, but IE do print all 'loading', 'loaded' and
'success'.
2. http://www.google.com/doesnothavethisjs.js
Just a simple error page returned by google.com
Firefox prints nothing, but IE prints 'loading', 'loaded' and 'success'
3. http://someserver/soemjs.js
This request would return an HTML showing cannot find file on server like
(2). It is on our own application server.
Firefox prints 'undefined', 'success' and then have script error about HTML
tag error (I guess because the return page is not a well-formed html).
IE prints 'loading', 'loaded' and 'success' with script error saying 'syntax
error'.
Seems that in IE, I cannot quite distinguish what is going on.
