javascript unexpected identifier

Question

I am trying to compress my JavaScript code to get less traffic on my site. It has been working fine, but now I came across an error I can't resolve.

I turned my ajax function into one line:

function(){if(xmlhttp.readyState==4&&xmlhttp.status==200){document.getElementById("content").innerHTML=xmlhttp.responseText;}}xmlhttp.open("GET","data/"+id+".html",true);xmlhttp.send();}

But the chrome console tells me there is an unexpected identifier on this line. Firefox says there is an semicolon missing on this line.

I have been trying to figure out what is wrong, but I can't find the error, can someone help me with this?

Answer 1

Yes, you have a } too many. Anyway, compressing yourself tends to result in errors.

function () {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        document.getElementById("content").innerHTML = xmlhttp.responseText;
    }
} // <-- end function?
xmlhttp.open("GET", "data/" + id + ".html", true);
xmlhttp.send();
}

Use Closure Compiler instead.
