如何在页面加载时获取HTML中的init值以控制Angularjs中的控件 app.controller（'doublePointCtrl'，函数（$rootScope，$scope，$http，$filter，Flash）{ var data=$scope.formData.mdpSunday； });
页面加载时，我无法在控制器中获取init值您需要等待变量为init，如何在页面加载时获取HTML中的init值以控制Angularjs中的控件 app.controller（'doublePointCtrl'，函数（$rootScope，$scope，$http，$filter，Flash）{ var data=$scope.formData.mdpSunday； });,html,angularjs,angularjs-scope,Html,Angularjs,Angularjs Scope,页面加载时，我无法在控制器中获取init值您需要等待变量为init，$watch它 您需要等待变量为init，$watchit 在设置值之前，您需要先读取ngInit值 第一个选项： 因此，您可以监听您的ngInit值，并在设置时读取您的数据。您可以使用$watch方法： 控制器 $scope.formData = {}; $scope.$watch('formData.mdpSunday', function (newVal, oldVal) { console.log(newV
$watch您需要等待变量为init，
$watch在设置值之前，您需要先读取
ngInitngInit$watch$scope.formData = {};
$scope.$watch('formData.mdpSunday', function (newVal, oldVal) {
console.log(newVal);
});
<body ng-app='app' ng-controller="ctrl" ng-init="data='5'">
<input type="text" ng-model="data">
</body>
(function(){
function Controller($scope) {
//Watch you ngInit value
$scope.$watch('data', function(){
//When your value is set, you can retrieve it
console.log($scope.data);
});
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
$scope.init = function(n){
$scope.data = n;
}
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
//Watch you ngInit value
$scope.$watch('data', function(){
//When your value is set, you can retrieve it
console.log($scope.data);
});
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
$scope.init = function(n){
$scope.data = n;
}
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
我认为秒选项更干净。您想在设置值之前读取
ngInitngInit$watch$scope.formData = {};
$scope.$watch('formData.mdpSunday', function (newVal, oldVal) {
console.log(newVal);
});
<body ng-app='app' ng-controller="ctrl" ng-init="data='5'">
<input type="text" ng-model="data">
</body>
(function(){
function Controller($scope) {
//Watch you ngInit value
$scope.$watch('data', function(){
//When your value is set, you can retrieve it
console.log($scope.data);
});
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
$scope.init = function(n){
$scope.data = n;
}
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
//Watch you ngInit value
$scope.$watch('data', function(){
//When your value is set, you can retrieve it
console.log($scope.data);
});
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
(function(){
function Controller($scope) {
$scope.init = function(n){
$scope.data = n;
}
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
我认为第二个选项更干净。。“唯一适当使用
ngInitngRepeatngInitngInitngRepeatngInit
