在我的 Laravel 项目中，我有一个 BusController.php 文件，我需要在其中运行 for() 循环。但是，循环不起作用。我也试过一个刀片来循环，但有同样的问题。

总线控制器.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\Bus;
use App\Bus_type;
use App\Company;
use App\Http\Requests;

class BusController extends Controller
{
    public function index()
    {
        $buses = Bus::all();
        $bus_types = Bus_type::all();
        $companies = Company::all();

        return view('admin.adding_bus', compact('buses', 'bus_types', 'companies'));
    }

    public function store(Request $request)
    {
        $bus = new Bus;
        $bus->company_name = $request->company_name;
        $bus->bus_type = $request->bus_type;
        $bus->bus_number = $request->bus_number;
        $bus->no_of_rows = $request->no_of_rows;
        $bus->no_of_columns = $request->no_of_columns;
        $seats = "";

        for ($i = 1; $i <= …

我试图在单击模态触发按钮时更改模态正文文本。模式正在打开，但模式正文文本没有改变。这是模态的代码：

<button type="button" class="btn btn-info open-modal" data-remote="false" data-toggle="modal"  data-target="#myModal">Register</button>

<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
    <div class="modal-dialog">

        <!-- Modal content-->
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Modal Header</h4>
            </div>
            <div class="modal-body">
                <p>Some text in the modal.</p>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>

    </div>
</div>

然后是防止默认事件的来源

$('.open-modal').click(function(e)
{
    e.preventDefault();
    alert('hello i am jquery');
    $('#myModal').modal('show');
});

为什么alert('你好我是jquery'); 行没有执行？
