Question

在我的laravel项目中，我使用资源控制器进行更新。但它不起作用。我试过但失败了。

            editUrl = url + '/' + id + '/edit';
            $.get( {{ route('editUrl') }}, {name:name, country:country, address:address, id:id}, function (data) {

路线/ web.php

Route::resource('peoples', 'PeopleController');

PeopleController.php

public function edit(People $people)
    {
        if($request->ajax()) {
            $request->validate([
                'name' => 'required',
                'address' => 'required',
                'country' => 'required',
            ]);

            $people = People::find($request->id);
            $people->name = $request->name;
            $people->address = $request->address;
            $people->country = $request->country;
            $people->save();

            return response()->json();
        }
    }

当我尝试输入浏览器http://localhost:8000/peoples时，我看到了这个错误。

路由[editUrl]未定义。（查看：C：\ xampp \ htdocs \ Tutorials Laravel \ Ajax的\资源\视图\ peoples.blade.php）

Answer 1

由于您没有为路线命名，因此无法在此处使用route()助手。相反，请尝试使用url()帮助程序生成URL。

url(id . '/edit')

但是，在这里我看到另一个问题，因为当JS执行时，id将会动态进入，此时Laravel助手已经执行了。所以，我建议采用以下方法：

url = {{ base_url() }} + '*apiPrefix*' + '/peoples/' + id + '/edit'

Answer 2

我编写的代码如下。它不起作用。这是对的吗？

$(document).on('click', '#UpdateForm', function () {
            name = $('#name').val();
            country = $('#country').val();
            address = $('#address').val();
            url = "{{ route('peoples.store') }}" + '*apiPrefix*' + '/peoples/' + id + '/edit';
            id = $(this).data('id');
            editUrl = url + '/' + id + '/edit';
            $.get( editUrl ), {name:name, country:country, address:address, id:id}, function (data) {
                console.log('success');
            });
        });
