javascript - Why doesn't the value attribute of the input change?

Question

Well I have this code in view:

<input id="CI.SiteName" type="text" value="" name="@@CI.SiteName" disabled="">

and then I doing some event that would call this function:

chooseSite = function () {
    var url = "/main/Ajax/GetSiteDetail?" +
        "&cid=" + escape(idSite);

    var ajx = sendAJAX(url, true);

    ajx.onreadystatechange = function () {
        if (ajx.readyState == 4) {
            var result = ajx.responseText;      
            result = "TOP";
            document.getElementById("CI.SiteName").value = result;
        }   
    }
}

in browser it changed to "TOP" but when I inspect element with firebug, the VALUE attribute of INPUT still "", not changed.

The value attribute is not synced with the actual value; that's what the value property is for.

This is not a problem though since you'll never use .getAttribute('value') but use the property .value to access the current value.
