这是我的ol li：

<ol class="dd-list" id="classroomdatalist">
    <li class="dd-item" data-id="2">
        <div class="dd-handle classroom_side-bdr"><b>Classroom</b></div>
        <c:forEach items="${records.cList}" var="records1">
            <ol class="dd-list" id="classroomlist${records1.classroomID}">
        <li id="cs1" class="dd-item" data-id="3" value="${records1.levelID}">
                    <div class="dd-handle">

    var clg = ${param.clg};
    var levelID = level;

    videoFile = document.getElementById("videoFile").value;
    soundFile = document.getElementById("soundFile").value;
    var classroomData = {
        videoFile:videoFile,
        soundFile:soundFile,
        levelID:levelID,
        clg:clg
    };
    $.ajax({
        type : "post",
        url : "classroomAdd",
        data: JSON.stringify(classroomData),
        dataType:'json',
        contentType:'application/json',
        mimetype:'application/json',
        cache : false,
        beforeSend : function(xhr) {
            xhr.setRequestHeader("Accept", "application/json");
            xhr.setRequestHeader("Content-Type", "application/json");
        },
        success : function(response) {
            console.log("Success: "+response.sucess);


            $("#classroomdatalist").append('<li>'+response.sucess+'</li>'); 

            $("#classroomcontent_div").hide();
        },
        error : function(xhr) {
            console.log("Sorry, there was a problem! " + xhr.status);
        },
        complete : function() {
            console.log("Request complete");
        }
    }); 
}

Answer 1

问题是你包括两次jQuery库。你有：

的jquery-1.8.3.js
jquery-1.3.2.min.js＆lt; - 删除这个

只保留一个并使用@SkyBuzz提供的代码：

var data = "Some data";
$( "#myId" ).append($('<li/>').html(data));

Answer 2

试试这个

var data="sample";
$("#sampledatalist").append($('<li/>').html(data));

我希望这能解决你的问题。
