我有一个选择标签, 当它的价值改变时, 我想根据这个新值从数据库中获得一些数据, 然后把这些新数据放到一个新的 div 上, 这个 div 包含一个接近的标记, 当用户点击它时, 新的 div 会隐藏, 我做了,除了隐藏新的 div, 一切正常, 除了隐藏新的 div, 我的关闭新 div 的j Query 是好的, 但现在, 我不认为我在jQuery 中做错了, 但我不知道哪里是我的错误, 会帮助我,

jQuery code

$(document).ready(function(){
$("#aqIoQuesSelector").on("change",function(){
        var IO = $("#aqIoQuesSelector").val();
        $("#aqSugInfo").html( <div class="closeSign1"></div> );
        $.getJSON("http://localhost/Mar7ba/InformationObject/giveContenfForIO/"+IO+"/TRUE",function(data){
            if(data.length>0){
                $("#aqSugInfo").css("text-align","right");
                for(var i=0;i<data.length;i++){
                    $("#aqSugInfo").append( <p><span class="aqoneContenSug"> +data[i]+ </span></p> );
                }
            }else{
                $("#aqSugInfo").append( <span class="successMessage">no suggesiont</span> );
            }
            $("#aqSugInfo").css("display","block");
        }); 
    });
});

$(document).ready(function(){
    $( .closeSign1 ).on( click , function() {
        $(this).parent().hide();
    });
});

notice that the sign close is used three time here , it works for the first time at the div aqSugQues , but doesn t work at the div aqSugInfo nor the div aqSugHints
