Question

以下php第一次运行。虽然在对PHP文件进行一次或两次往返之后，javascript控制台会抛出错误。一旦错误被抛出，应用程序就会停止一起工作。

HTML：

<body>
    <div class="container" ng-controller="case4Ctrl">
        <div class="row">
            <h1 class="text-center">Enter a number to see if it is prime</h1>
            <input type="text" ng-model="number" value="" placeholder="" ng-keyup="isprime()">
            {{isprime}}
        </div>

    </div>
    <script>
     var app = angular.module('case4', []);

     app.controller('case4Ctrl', ['$scope', '$http', function ($scope, $http) {
        $scope.isprime = function(){
            console.log($scope.number);
            if($scope.number){
                console.log("test");
                $http.get("./isPrime.php?number=" + $scope.number).success(function(data){
                    $scope.isprime = data;
                });
            }
        };
     }])

    </script>
    <!-- jQuery -->

    <!-- Bootstrap JavaScript -->
    <script src="//netdna.bootstrapcdn.com/bootstrap/3.1.0/js/bootstrap.min.js"></script>
</body>

PHP：

<?php 
$number = $_GET['number'];


function isPrime($param){
    if ($param == 1){ return "1 is never a prime number";}
    if ($param == 2){ return "2 is the only even prime number";}

    for ($i = 3; $i < $param; $i += 2)  {
       if (($param % $i) == 0){ return $param. " is not a prime number"; }
    }

    return $param ." is a prime number";

}

echo isPrime($number);


?>

Answer 1

ng-keyup="isprime()"

然后在你的代码中写下：

 $scope.isprime = data;

显然不会起作用，数据不是函数，而是服务器返回的字符串。它在服务器之前工作，因为isprime函数尚未被字符串覆盖。

将keyup处理程序更改为

ng-keyup="getIsPrime()"

和相应的函数名称

 $scope.getIsPrime=function(){...}

TypeError：string不是一个函数Angularjs，PHP
