当我点击＆＃34;注册＆＃34;超链接（放置在登录模式窗体上），我的注册模式弹出，但立即消失。我是jquery和javascript的noob，所以这没有意义。我尝试添加以下代码（它也不起作用），而不是我在主代码上的代码。这是我的github页面链接，可帮助您了解问题：https://dola108.github.io/
$('.message a').click(function(){
modal.style.display = "none";
$("#RegisterModal").css("display","block");
})
我的主要代码是：
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script type="text/javascript">
var modal = document.getElementById('LoginModal');
var modalreg = document.getElementById('RegisterModal');
var login = document.getElementById("butn");
var reg = document.getElementById("butn0");
var span = document.getElementsByClassName("close")[0];
var span1 = document.getElementsByClassName("close")[1];
login.onclick = function() {
modal.style.display = "block";
}
reg.onclick = function() {
modalreg.style.display = "block";
}
$('.message a').click(function(){ //message is the class of the //paragraph containing the link
modalreg.style.display = "block";
})
span.onclick = function() {
modal.style.display = "none";
}
span1.onclick = function() {
modalreg.style.display = "none";
}
window.onclick = function(event) {
if (event.target.id == 'LoginModal') {
modal.style.display = "none";
}
if (event.target.id == 'RegisterModal') {
modalreg.style.display = "none";
}
}
</script>
这是我的整个HTML代码：

这里是模态的css部分：
.message{
font-family: Helvetica Neue;
color: #acacac;
}
.modal {
display: none;
position: fixed;
z-index: 1;
left: 0;
top: 0;
width: 100%;
height: 100%;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0,0.7);
}
/* Modal Content/Box */
.modal-content {
background-color: transparent;
margin: 3% auto;
padding: 5px 5px ;
width: 470px;
height: 530px;
}
/* The Close Button */
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}
/* input fields */
input[type=mail], input[type=password], input[type=name] {
width: 60%;
padding: 9px;
margin: 5px 0 16px 0;
display: table;
border: none;
background: #f1f1f1;
}
/* when the inputs get focus */
input[type=mail]:focus, input[type=password]:focus,
input[type=name]:focus {
background-color: #ddd;
outline: none;
}
hr {
width: 90%;
border: 1px solid #f1f1f1;
margin-bottom: 20px;
margin-left: -3px;
color: #acacac;
}
.clearfix::after {
content: "";
clear: both;
display: table;
}
/* Change styles for cancel button and signup button on extra small
screens
*/
@media screen and (max-width: 300px) {
.cancelbtn, .signupbtn {
width: 100%;
}
}
答案 0 :(得分：0)
抱歉，一开始并不了解问题的目标。实际上，你的模态并没有消失。这是您点击<a>后重新加载的页面。解决方案：
$('.message a').click(function(event){
event.preventDefault();
modalreg.style.display = "block";
modal.style.display = "none";
});
