设置Laravel Form :: number的Maxlength（

Question

我有这段代码

{{ Form::number('amount', (isset($logged_in_user->paymentConfirmation->amount) ? floor($logged_in_user->paymentConfirmation->amount) : null), ['class' => 'form-control', 'maxlength' => '13','step' => '1']) }}

如何将长度限制为13位数？

Answer 1

Laravel Collective Forms将Form::number呈现为<input type="number">元素。所以你需要在这里使用max，它的值必须是允许的最大整数：

{!! Form::number('amount', (isset($logged_in_user->paymentConfirmation->amount) ? floor($logged_in_user->paymentConfirmation->amount) : null), ['class' => 'form-control', 'max' => '9999999999999', 'step' => '1']) !!}
