You can't set a server session variable directly from JS. 您无法直接从JS设置服务器会话变量。
To do that you can make an AJAX call to a PHP script passing the value you want to set, and set it server side: 为此，您可以对PHP脚本进行AJAX调用，传递您要设置的值，并将其设置为服务器端：
$('#editRole').on('show.bs.modal', function (e) {
$roleID = $(e.relatedTarget).attr('data-id');
//ajax call
$.ajax({
url: "set_session.php",
data: { role: $roleID }
});
});
set_session.php set_session.php
//preliminary code
Session::put('roleID', $request->input('role') );

Above answer and from other resources together helped me out to make example similar to situation like ' Setting the session using AJAX in laravel '. 上面的答案和其他资源一起帮助我做出类似“ 在laravel中使用AJAX设置会话 ”的情况。
Im posting simple example, which other users might found this helpful. 我发布简单的例子，其他用户可能会发现这有用。
View - ajax_session.blade.php 查看 - ajax_session.blade.php
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#submit').on('click',function(){
// show that something is loading
$('#response').html("<b>Loading response...</b>");
$.ajax({
type: 'POST',
url: '/set_session',
data: $("#userform").serialize()
})
.done(function(data){
// show the response
$('#response').html(data);
})
.fail(function() {
// just in case posting your form failed
alert( "Posting failed." );
});
// to prevent refreshing the whole page page
return false;
});
});
</script>
</head>
<body>
<form id="userform">
{{ csrf_field() }} <!--required - otherwise post will fail-->
<input type="text" id="uname" name="uname" required/>
<button type='submit' id="submit">Submit</button>
<div id='response'></div>
</form>
</body>
</html>
routes.php routes.php文件
Route::get('session_form', function () {
return view('ajax_session');
});
Route::post('set_session', 'SessionController@createsession');
Route::get('allsession', 'SessionController@getsession');
Controller - sessionController.php 控制器 - sessionController.php
public function createsession(Request $request)
{
\Session::put('uname', $request->uname);
echo "session created";
}
public function getsession()
{
dd(\Session::get('uname'));
}
You can check this by running localhost:8000/session_form . 您可以通过运行localhost:8000/session_form来检查这一点。 And you can also check session separately by localhost:8000/allsession . 您还可以通过localhost:8000/allsession单独检查会话。
Hope this helps!!! 希望这可以帮助！！！
