我正在尝试在我的项目中进行更新，用户单击链接，他们就会被带到该页面(我有该部分正在工作)，他们可以在其中进行更改。目前我已经创建并更新函数，但当用户单击按钮时没有任何反应。

这是我的 home.blade.php，用户单击链接将其带到另一个页面:

最佳答案

When I click on the button in edit.blade ,nothing happends

在您定义的 edit.blade.php 和表单中没有提交按钮

替换:

<button type="submit" class="btn btn-info pull-right btn-sm"><i class="fa fa-plus"></i>Add status
            </button>

在 edit.blade.php 中使用按钮代码

如果您有任何错误，请告诉我
