javascript - onchange不能用？

Question

function gettime(str) {

        var strURL="/Doctor/booking/gettime.jsp?datepicker="+str;
        var req = getXMLHTTP();

        if (req) {

            req.onreadystatechange = function() {
                if (req.readyState == 4) {
                    // only if "OK"
                    if (req.status == 200) {
                        document.getElementById('d11').innerHTML=req.responseText;
                    } else {
                        alert("There was a problem while using XMLHTTP:\n" + req.statusText);
                    }
                }
            }
            req.open("GET", strURL, true);
            req.send(null);
        }
    }
<b>Date:<input id="d11" type="text" name="datepicker" onClick="WdatePicker()" onchange="gettime(this.value)"/></b>

当我单击文本框、提醒日期选择器并选择日期时，文本框应更改其值。但事实并非如此。我可以用什么方法解决呢？

此外，当我直接输入此网址时:/Doctor/booking/gettime.jsp?datepicker=2012-02-02 我看到了我想要的输出。

而不是:

document.getElementById('d11').innerHTML=req.responseText;

尝试:

document.getElementById('d11').value=req.responseText;
