ajax访问数据，保存修改数据，保存成功，有时候执行，有时候不执行回调函数！我测试得出的结论是：id小于10的不执行，大于10的就执行回调函数，抛出我给定的alert("修改成功");

代码如下：

function SaveOpinion() {
    if (g_OpinionID == undefined || g_OpinionID <= 0) return;

    var content = "";
    KE.sync('txtEditor');
    content = document.getElementById('txtEditor').value;
    if (content == "") {
        alert("please inpuer content!");
        return;
    }

        content = escape(content);
    var title = "";
    title = $F('opinion_title');
    if (title == "") {
        alert("please input title");
        return;
    }
        title = escape(title);
    var params = "id=" + g_OpinionID + "&title=" + title + "&content=" + content;
    try {

        new Ajax.Request('/Service.aspx?command=updateeditorial', {
            method: "post",
            parameters: params,
            onSuccess: function (xmlhttprequest) {
                onSaveOpinion(xmlhttprequest.responseText);
            }
        });
     
    }
    catch (e) {
        alert("opinion_approve.js->SaveOpinion:" + e.message);
    }
}

function onSaveOpinion(responseText) {
    try {
        if (responseText == undefined || responseText == "" || responseText == "Hi,Asia Trade Watch！") {
            return;
        }
        else {
            alert("Save Success!");//有时候执行到这行，有时候不执行
            document.getElementById("opinion_title").value = "";
            KE.html('txtEditor', "");
            ListOpinions(0);
        }
    }
    catch (e) {
        alert("opinion_approve.js->onSaveOpinion:" + e.message);
    }
}

可能问题描述得不是很清楚，后面补充，希望各位高手帮帮忙！
