Laravel senden Daten an mysql mit AJAX

Question

Ich bin stecken mit dem Erstellen einer Funktion in AJAX, die einen Wert von Variable "Code2" nehmen würde und senden Sie es an den Controller, die es an die Datenbank senden würde. Problem Ich bekomme die ganze Zeit ist:

Ist das wirklich funktioniert? Ach übrigens: newLat: code2

So ist es Art aber statt newLat funktioniert: code2 sollte es newLat sein: (HTML-Code in Variable code2 definiert) Wie kann ich dieses Problem beheben?

JS:

$(function() { 
    $('.content-link').click(function(e) { 
     e.preventDefault(); 
     $('#content-link2').load($(this).attr("href"), function() { 
      $('#content').draggable({ 
       containment: "#content-link2", 
       scroll: false 
      }); 
     }); 
    }); 
    return false; 
}); 
var code2 = ""; 
document.getElementById("content-link2").onmousedown = function() { 
    mousedown(); 
}; 
document.getElementById("content-link2").onmouseup = function() { 
    mouseup(); 
}; 

function mousedown() { 
    code2 = document.getElementById("content-link2").innerHTML; 
    console.log(code2); 
} 

function mouseup() { 
    code2 = document.getElementById("content-link2").innerHTML; 
    console.log(code2); 
} 

AJAX:

function updateDatabase(newCode) 
{ 
    code2 = document.getElementById("content-link2").innerHTML; 
    console.log(code2); 
    // make an ajax request to a PHP file 
    // on our site that will update the database 
    // pass in our lat/lng as parameters 
    $.post('http://localhost/template', { 
      _token: $('meta[name=csrf-token]').attr('content'), 
      newCode: ("code2"), 
     }) 
     .done(function(code2) { 
      alert(code2); 
     }) 
     .fail(function() { 
      alert("error"); 
     }); 
} 

Route:

Route::group(['middleware' => ['web']], function() { 

    Route::get('home', 'BuilderController@homepage'); 
    Route::get('template', 'BuilderController@templates'); 
    Route::post('template', 'BuilderController@postDB'); 
    Route::get('logout', 'BuilderController@getLogout'); 
}); 

Controller:

class BuilderController extends Controller 
{ 
    function templates() 
    { 
     $templates = Template::all(); 
     return view('layouts/template', ['templates' => $templates]); 
     $id = $templates->id; 
    } 
    function homepage() 
    { 
     return view('layouts/home'); 
    } 
    public function getlogout() 
    { 
    \Auth::logout(); 
    return redirect('/home'); 
    } 
    public function postDB(Request $request) { 
     $newLat = $request->input('newCode'); 

     return "Is This Really Working? Oh by the way: newLat: $newLat"; 
    return redirect('layouts/template', ['templates' => $templates]); 
    } 
} 

Blade:

@extends('layouts.master') @section('title', 'Website Builder') @section('content') 
<div class="container template_class "> 
    @foreach ($templates as $template) 
    <a class="content-link" href="{{ asset($template->file)}}">

prüfen /path/to/project/root/storage/logs/laravel.log für das, was Interner Serverfehler auftritt. Wenn keine Protokolldatei vorhanden ist, stellen Sie sicher, dass APP_DEBUG in /path/to/project/root/.env auf true festgelegt ist.
