我为我的页面创建了一个切换登录/注册模板。
然而,一旦你点击Register
,它就会发现某些元素不可见。
这是fiddle。
以下是整个代码。
HTML
<div id="container">
<button id="bt1" type="button"> Login
</button>

的Javascript
function swap(login, register) {
document.getElementById(login).style.display = 'block';
document.getElementById(register).style.display = 'none';
}
document.getElementById('bt1').addEventListener('click',function(e){
swap('login','register');
});
document.getElementById('bt2').addEventListener('click',function(e){
swap('register','login');
});
function validateForm() {
var f_name = document.forms["register"]["F_Name"].value;
if(f_name == null || f_name == "")
{
alert("First Name is required");
return false;
}
var l_name = document.forms["register"]["L_Name"].value;

return false;
}
var email = document.forms["register"]["email"].value;
var atpos = email.indexOf("@");
var dotpos = email.lastIndexOf(".");
if (atpos< 1 || dotpos<atpos+2 || dotpos+2>=email.length) {

尝试使用以下方法更改#container样式:
#container {
position: fixed;
top: 50%;
left: 50%;
max-height: 100%;
overflow-y: auto;
transform: translate(-50%, -50%);
}
