javascript - AngularJS JavaScript 登录语法错误

Question

我对 AngularJS 很陌生。我正在尝试使用 AngularJS 实现简单的登录页面。但它抛出 错误:[$parse:syntax] 语法错误: token “未定义”不是表达式 [login(userName,] 的列 null 处的主表达式。请指导我。

index.html -

<div class="mainBdy" ng-controller="loginForm">
      <form ng-submit=login(userName, password)>
        <div class="userName">
          <label for="usrNm">USERNAME</label>
          <input type="text" id="usrNm" ng-model="userName"/>
        </div>
        <div class="password">
          <label for="pwd">Password</label>
          <input type="password" id="pwd" ng-model="password"/>
        </div>
        <div class="btnSection">
          <button>LOGIN</button>
          <button>SIGN UP</button>
        </div>
      </form>
    </div>

  <div ng-view></div>

Controller.js -

angular.module('myApp.controllers', [])
.controller('loginForm', function($scope) {
    $scope.users = [{name: "Neha", pwd: "Neha"}, {name: "Sneha", pwd: "Sneha"}];
$scope.login = function (userName, password) {
    if (userName === "Neha" && password === "Neha") {
        alert("Welcome");
    } else {
        alert("Invalid Login");
    }
}
});

我猜你错过了引号，请更改:

<form ng-submit=login(userName, password)>

至

<form ng-submit="login(userName, password)">
