我有一个表单,当我提交它时,它将一些对象推送到我的数组。在该表单下面,我有一个表格,显示该数组中的所有项目。我希望我的表在推送新项目时自动更新(不刷新页面)。
提交按钮:
<button type="submit" class="btn btn-default" ng-click="updateTable()">Pay</button>
在我的控制器中:
$scope.updateTable = function() {
setTimeout(function () {
$scope.$apply();
$scope.$digest();
}, 0);
};
然而,它不起作用。 我尝试了不同的方法,比如$ watch service,但我得到了相同的结果。
表
<div class="row paytable">
<div class="col-xs-10 col-xs-offset-1">
{{payments.length}}
<table class="table table-hover ">
<tr>
<td>Id</td>
<td>Amount</td>
<td>Cause</td>
</tr>
<tr ng-repeat="item in payments">
<td>{{item.id}}</td>
<td>{{item.amount}}</td>
<td>{{item.cause}}</td>
</tr>
</table>
</div>
</div>
控制器
app.controller('mainController', [ 'user', '$rootScope', '$scope', 'payment', '$timeout', function(user, $rootScope, $scope, payment, $timeout) {
user.getUsers();
user.newUser();
$rootScope.currentUser = user.currentUser();
$scope.payments = payment.getPayments();
$scope.newPayment = payment.newPayment;
$scope.updateTable = function() {
setTimeout(function () {
console.log('apply ------------');
$scope.$apply();
$scope.$digest();
}, 0);
};
$scope.showPayMessage = function() {
console.log('im here');
$scope.showSM = true;
$timeout(function() {
$scope.showSM = false;
}, 2000);
};
}]);
付款 - 我的数组操作服务。
表格
<div class="newpay row" >
<div class=" col-xs-10 col-xs-offset-1">
<h1>Hello, {{currentUser.name}}</h1>
<h4 ng-show="showSM" class="bg-success">Payment confirmed</h4>
<form name="inputform" ng-submit="newPayment(amount, cause); showPayMessage();">
<div class="form-group">
<label for="exampleInputEmail1">Amount</label>
<input type="number" name="amount" ng-model="amount" class="form-control" id="exampleInputEmail1" placeholder="Amount" required>
</div>
<div class="form-group">
<label for="exampleInputPassword1">Cause</label>
<input type="text" name="cause" ng-model="cause" class="form-control" id="exampleInputPassword1" placeholder="Cause" required>
</div>
<button type="submit" class="btn btn-default" ng-click="updateTable()">Pay</button>
</form>
</div>
</div>
payments: {{payments.length}}
<payments-table payments="payments"></payments-table>
要显示该表,我创建了指令。

$scope.$apply
和$scope.$digest
更适合与第三方库或测试合作。在您的情况下,Angular非常了解您的更改。问题是,在提交新项目后,应再次查询驻留在服务中的payments
数组(除非您直接引用该数组,否则不应进行查询)。
像这样:
查看
<form name="inputform" ng-submit="onSubmit()">
<强>控制器强>
$scope.onSubmit = function() {
newPayment($scope.newItemAmount, $scope.newItemCause); // Assuming they are properties in the controller
showPayMessage();
$scope.payments = payment.getPayments(); // getting the updated array
}
