此答案基于以下答案：如何在AngularJS的输入字段中自动大写第一个字符？。
我以为您想要的是一个解析器函数，如下所示：
angular .module('myApp', []) .directive('capitalize', function() { return { require: 'ngModel', link: function(scope, element, attrs, modelCtrl) { var capitalize = function(inputValue) { if (inputValue == undefined) inputValue = ''; var capitalized = inputValue.toUpperCase(); if (capitalized !== inputValue) { // see where the cursor is before the update so that we can set it back var selection = element[0].selectionStart; modelCtrl.$setViewValue(capitalized); modelCtrl.$render(); // set back the cursor after rendering element[0].selectionStart = selection; element[0].selectionEnd = selection; } return capitalized; } modelCtrl.$parsers.push(capitalize); capitalize(scope[attrs.ngModel]); // capitalize initial value } }; });<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script><div ng-app="myApp"> <input type="text" ng-model="name" capitalize></div>
