提问by swapna
am using the patterns like "/[a-zA-Z0-9][^\s]/" and "/\s/" but no one is working. can you give any solution for this "ng pattern for input tag and which allows oly alphanumeric but it does not allow spaces in the input field ".
我正在使用诸如“/[a-zA-Z0-9][^\s]/”和“/\s/”之类的模式，但没有人在工作。您能否为此“输入标签的ng模式提供任何解决方案，它允许使用oly字母数字，但不允许在输入字段中使用空格”。

Try the following pattern: /^\s*\w*\s*$/
尝试以下模式： /^\s*\w*\s*$/
<script>
angular.module('textInputExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.text = 'guest';
$scope.word = /^\s*\w*\s*$/;
}]);
</script>
<form name="myForm" ng-controller="ExampleController">
Single word: <input type="text" name="input" ng-model="text" ng-maxlength="5"
ng-pattern="word" required ng-trim="">
