我想将用户名和ID从php登录页面传递给angularjs控制器onload。我尝试通过ng-init调用basicDetails（username，id）。此功能在主控制器末端触发。另外一个问题是在basicDetails函数内部将参数传递给angularjs变量print传递值，在它外面显示为空
<body ng-controller="mainController" ng-init="basicDetails('<?php echo$_SESSION["username"];?> ','<?php echo$_SESSION["itmsNo"];?> ')">
<center>
<div >
<b><?php echo htmlspecialchars($_SESSION["username"]); ?></b><br>
<a href="reset-password.php" class="btn btn-warning">Reset Password</a><br>
<a href="logout.php" class="btn btn-danger">Sign Out</a>
</div> </center>
<!-- Main div showing different templates loaded by ng-view directive -->
<div class="container main" ng-view>
</div>
Maincontroller.js
templeApp.controller('mainController', ['$scope','$rootScope','$http','webService', function($scope,$rootScope, $http,webService,user) {
$rootScope.loggedUser;
$scope.itmsNo;
// This function trigger by ng-init , but called end of main controller
$scope.basicDetails = function(logedUser,itmsNo){
$rootScope.loggedUser =logedUser;
$scope.itmsNo =itmsNo;
console.log($scope.loggedUser ); // console print actual value
}
console.log('..'+$scope.loggedUser ); // console print empty value
$scope.user = webService.userData('impl/userData.php',$scope.loggedUser);
}]);
正如您所说，ng-init在其余的控制器代码之后运行。这就是为什么尝试在undefined之外登录时会得到basicDetails的原因。尚未设置，因为basicDetails稍后进行设置。
因此，请在basicDetails内运行所有初始化代码：
templeApp.controller('mainController'...
$scope.basicDetails = function(logedUser, itmsNo) {
$rootScope.loggedUser;
$scope.itmsNo;
$rootScope.loggedUser = logedUser;
$scope.itmsNo = itmsNo;
console.log($scope.loggedUser);
$scope.user = webService.userData('impl/userData.php', $scope.loggedUser);
}
}}
您可以将其从basicDetails重命名为init之类，这样更有意义。
