表单对<script type="text/javascript"> @if (Auth::user()->roleplay->health_points >= 100) setHealth(1); @elseif setHealth(0.{{ Auth::user()->roleplay->health_points }}); @endif @if (Auth::user()->roleplay->energy_points >= 100) setEnergy(1, {{ Auth::user()->roleplay->energy_points }}); @elseif setEnergy(0.{{ Auth::user()->roleplay->energy_points }}, {{ Auth::user()->roleplay->energy_points }}); @endif @if (Auth::user()->roleplay->hygiene_points >= 100) setHygiene(1, {{ Auth::user()->roleplay->hygiene_points }}); @elseif setHygiene(0.{{ Auth::user()->roleplay->hygiene_points }}, {{ Auth::user()->roleplay->hygiene_points }}); @endif @if (Auth::user()->roleplay->hunger_points >= 100) setHunger(1, {{ Auth::user()->roleplay->hunger_points }}); @elseif setHunger(0.{{ Auth::user()->roleplay->hunger_points }}, {{ Auth::user()->roleplay->hunger_points }}); @endif </script>无效时使用ng-disabled。设置控制器的最大长度。

最大长度：

ng-maxlength

伍禁用

ng-maxlength="maxlength"

这是一个有效的例子。

如果您想使用简单的解决方案ng-disabled="form1.phone.$invalid"！

祝你好运。

如何在maxlength超过后禁用键盘输入？
