使用普通javascript通过AJAX发布时，Textarea为null

Question

当我尝试发布这个textarea时，它什么也没发送，显然没有返回该字段。

所有其他输入字段都可以。

我已经阅读过并且每个人都说要确保.value是在getelementid之后添加的，无论如何我都在做，所以我不确定是什么问题。

我正在使用Bootstrap 3，以防万一。

更新：我刚刚在textarea字段中进行了测试和硬编码的文本。那顺利通过了。但是我在表单中键入的任何文本都不会被传递。我想这可能是一个Bootstrap 3错误。

还有其他人知道吗？

使用Javascript：

var http_request = false;

function show_hint(p_hint_text, p_span) {
    document.getElementById(p_span).innerHTML = p_hint_text;
}

function makePOSTRequest(url, parameters, SpanName) {
    http_request = false;
    if (window.XMLHttpRequest) { // Mozilla, Safari,...
        http_request = new XMLHttpRequest();
        if (http_request.overrideMimeType) {
            http_request.overrideMimeType('text/xml');
        }
    } else if (window.ActiveXObject) { // IE
        try {
            http_request = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                http_request = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
        }
    }
    if (!http_request) {
        alert('Cannot create XMLHTTP instance');
        return false;
    }

    http_request.onreadystatechange = function () {
        if (http_request.readyState == 4) {
            if (http_request.status == 200) {
                //alert(http_request.responseText);
                result = http_request.responseText;
                document.getElementById(SpanName).innerHTML = result;
                document.getElementById(StatusName).innerHTML = 'Ready';
            } else {
                alert('There was a problem with the request.');
            }
        }
    };
    http_request.open('POST', url, true);
    http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    alert(parameters);
    http_request.send(parameters);
}


function Contact(obj, SpanName, StatusName) {
    var curDateTime = new Date(); //For IE
    var poststr = "gid=" + encodeURI(document.getElementById("gid").value) +
        "&tid=" + encodeURI(document.getElementById("tid").value) +
        "&cid=" + encodeURI(document.getElementById("cid").value) +
        "&recid=" + encodeURI(document.getElementById("recid").value) +
        "&item_ip=" + encodeURI(document.getElementById("item_ip").value) +
        "&item_userid=" + encodeURI(document.getElementById("item_userid").value) +
        "&item_author=" + encodeURI(document.getElementById("item_author").value) +
        "&fromajax=" + encodeURI(document.getElementById("fromajax").value) +
        "&action=" + encodeURI(document.getElementById("action").value) +
        "&active=" + encodeURI(document.getElementById("active").value) +
        "&message=" + encodeURI(document.getElementById("message").value);
    var SpanName = SpanName;
    var StatusName = StatusName;
    //alert (SpanName);
    alert(poststr);
    makePOSTRequest('http://fakedomain.com', poststr, SpanName);
}
