如何使用Angular JS删除空的前导空格 [英] How to Remove Empty leading, trailing spaces using Angular JS

问题描述

大家好，



我有一个文本框，我在哪里使用Angular JS ..我的代码是



< input type =text

name =XX

class =username

ng- model =XX

ng-pattern =/ \s /

ng-trim =false

required占位符= >



在Span我用过：



ng-show =$ scope.UsernameInvalid>

输入的用户名不是有效的用户名，也不具有领先的尾随空格







哪个不行...所以请尽快推荐我。
