我有这个警告框，显示在表单中没有名称或没有类别或没有描述，我已经使用此警报框但在其他页面中使用php，但是，在此页面中我使用jquery来打印出来我只能一键关闭它，实际上需要两次点击才能关闭它。
jquery的
$("#UploadCover").click(function(){
if(!$("#CoverName").val()){
$(".navbar-container").append('<div class="alert danger">'+
'<span class="closebtn" onclick="this.parentElement.style.display=\'none\';">×</span>' +
'<strong>Error!</strong> Must have a name!'+
'</div>');
}else{
var sel1 = $("#addArtCat1").find("option:selected").val();
var sel2 = $("#addArtCat2").find("option:selected").val();
var sel3 = $("#addArtCat3").find("option:selected").val();
var sel4 = $("#addArtCat4").find("option:selected").val();
var sel5 = $("#addArtCat5").find("option:selected").val();
var count = 0;
var selArray = [sel1, sel2, sel3, sel4, sel5];
for(var i=1 ; i <= 5 ; i++){
if(selArray[i] == "---"){
count++
}
}
if(count >= 4){
$(".navbar-container").append('<div class="alert danger">'+
'<span class="closebtn" onclick="this.parentElement.style.display=\'none\';">×</span>' +
'<strong>Error!</strong> Must at least chose a category'+
'</div>');
}else{
if(!$("#CoverDescription").val()){
$(".navbar-container").append('<div class="alert danger">'+
'<span class="closebtn" onclick="this.parentElement.style.display=\'none\';">×</span>' +
'<strong>Error!</strong> Must have a description'+
'</div>');
}else{
alert("fsdfds");
}
}
}
});

为什么要在（.nvabar）类中追加div和span？您可以轻松地使用锚标记来显示和隐藏弹出窗口
