我在不同的php文件中创建了两个表单，一个是Login表单，另一个是Register表单，然后菜单中有两个Login和Register按钮 如何让这些按钮以模态显示其形式？

你可以使用ajax查询来完成它，所以我想给你一个如何做到这一点的例子：
HTML和JS：
<body>
<div id="my_modal" class="modal"></div>
<button onclick="showLoginModal()">Login</button>
<button onclick="showRegisterModal()">Register</button>
</body>
<script>
function showLoginModal(){
$.ajax({
url:'php/login_content.php',
type:"GET",
cache:false,
success:function(html){
$("#my_modal").html(html);
$('#my_modal').modal();
}
});
event.preventDefault();
}
function showRegisterModal(){
$.ajax({
url:'php/register_content.php',
type:"GET",
cache:false,
success:function(html){
$("#my_modal").html(html);
$('#my_modal').modal();
}
});
event.preventDefault();
}
</script>
login_content.php文件：
<?php ?><div class="modal-content">
<form action="" method="post">
User
<input name="user_name" id="user_name" type="text"> Password
<input name="user_pass" id="user_pass" type="password">
<button type="submit" id="login">Login</button>
</form>
register_content.php文件：
<?php ?>
<div class="modal-content">
<form action="" method="post">
Username
<input name="user_name" id="user_name" type="text">
Password
<input name="user_pass" id="user_pass" type="password">
Confirm Password
<input name="user_pass" id="user_pass" type="password">
<button type="submit" id="login"> Register</button>
</form></div>
问候！

我会充实地发表我对达尔文的回答，以及你能看到我所说的话。
现在，我警告你有一个让用户进入登录页面的后备方式，以防万一javascript因为某种原因无法工作（并且有很多原因导致用户不会），但是那就是说。
此处的代码并不完全正确，因为它涉及多个文件，要获得完整的工作演示，请转到This Plunkr
// Code goes here
$(function() {
$('.modal-btn').on('click', function(e) {
e.preventDefault();
var id = this.id;
$('#login-register-modal').load(id + '_content.html', function(response, status) {
if (status == 'success')
$('#login-register-modal').modal();
});
})
