I need to have the index of an object in array so I can delete this part of the array. I tried using this:

var index = this.urenRegistratie.indexOf(newDatum);

But it keeps returning -1 and I don't know why this is happening.

this is the part of the code I have. it gets data out of a form in html and places that into my array, now I already have an if statement ready ( exisitingDatum ) , my code needs …

我是 laravel 的新手，我想学习它。我正在尝试克隆一个github存储库。存储库告诉我我需要克隆它，然后运行“ composer install ”命令。但我收到以下错误：

[ RuntimeException ] 找不到受支持的加密器。密码和/或密钥长度无效。

脚本 php artisan clear-compiled 处理返回的 post-install-cmd 事件，错误代码为 1

我尝试在 google 上搜索此错误，它告诉我将密码更改为 ' AES-256-CBC'。但是当我检查密码时，它有“ AES-256-CBC ”。

有谁知道如何解决这个问题？
