ng-pattern用于排除字符列表

Question

I am looking for the ng-pattern for my input field which is excluding these special characters:

[ ] : ; | = + * ? < > / \ ,

I don't want the user input has these characters above. Please help.

Answer 1

You have to escape the \\ and the ] :

ng-pattern="/^[^[\]:;|=+*?<>/\\,]+$/"

pattern automatically adds the /^ and the $/ so:

pattern="[^[\]:;|=+*?<>/\\,]+"

 var app = angular.module('app', []); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.3/angular.min.js"></script> <div ng-app='app'> <form name="myForm"> <input name="field" ng-model="something" ng-pattern="/^[^[\\]:;|=+*?<>/\\\\,]+$/"> {{ myForm.field.$error }} </form> </div> 

Answer 2

This is what you are looking for

^[^[:;|=+*?<>\/\\,\]]+$

You can see what it does at the following link

Answer 3

this should work

"^[^\[\]:;|=\+\*\?<>\/\\]+$"

if it doesn't work with HTML then u can use

"^[^\\\\[\\\\]:;|=\\\\+\\\\*\\\\?<>\\\\/\\\\\\]+$"
