我是角色的新手，目前在表格提交上更新表数据时遇到问题。这是我的观点：
<div class="container-fluid">
<div class="row">
<div class="col-md-12" ng-controller="feeStatement">
<panel panel-class="panel-sky" heading="Add Fee Details">
<panel-controls>
<panel-control-collapse></panel-control-collapse>
</panel-controls>
<div id="alert" class="alert alert-danger hide">
<strong>Error</strong> Unable to save the course data.<br><br>
<ul>
<li id="error"></li>
</ul>
</div>
<form ng-submit="submit(credentials)" ng-controller="feeStatement" class="form-horizontal row-border">
<div class="form-group">
<label for="fieldname" class="col-md-3 control-label">Item Description</label>
<div class="col-md-6">
<textarea name="description" id="fieldabout" class="form-control autosize" rows="2" ng-model="credentials.description"></textarea>
</div>
</div>
<div class="form-group">
<label for="fieldname" class="col-md-3 control-label">Due Date</label>
<div class="col-md-6">
<datepicker ng-model="dt" min-date="minDate" show-weeks="true" class="datepicker"></datepicker>
</div>
</div>
<div class="form-group">
<label for="fieldname" class="col-md-3 control-label">Amount Payable</label>
<div class="col-md-6">
<input name="amount_payable"
type="number"
placeholder="Numbers only"
required
ng-model="credentials.amount_payable"
class="form-control">
</div>
</div>
<div class="form-group">
<label for="fieldname" class="col-md-3 control-label">Total Collected</label>
<div class="col-md-6">
<input name="total_collected"
type="number"
placeholder="Numbers only"
required
ng-model="credentials.total_collected"
class="form-control">
</div>
</div>
<div class="form-group">
<label for="fieldname" class="col-md-3 control-label"></label>
<div class="col-md-6">
<input type="submit" class="finish btn-success btn" value="Submit" />
</div>
</div>
</form>
</panel>
<panel panel-class="panel-sky" heading="Fee Details">
<panel-controls>
<panel-control-collapse></panel-control-collapse>
</panel-controls>
<p ng-hide="isValid(feedetails)" class="ng-hide">No fee statements for the student.</p>
<div ng-show="isValid(feedetails)" class="table-responsive">
<table class="table">
<thead>
<tr>
<th style="padding-right:100px">Item Description</th>
<th>Due Date</th>
<th>Amount Payable</th>
<th>Total Collected</th>
<th>Outstanding</th>
<th>Fine</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in feedetails">
<td align="left"><i>{{item.description}}</i></td>
<td align="left"><i>{{item.duedate}}</i></td>
<td align="left"><i>{{item.amount_payable}}</i></td>
<td align="left"><i>{{item.total_collected}}</i></td>
<td align="left"><i>{{item.outstanding}}</i></td>
<td align="left"><i>{{item.fine}}</i></td>
</tr>
</tbody>
<form ng-controller="feeStatement"><input type="submit" class="finish btn-success btn" ng-click="test()" value="Submit" /></form>
</table>
</div>
</panel>
</div>
</div>
</div> <!-- container-fluid -->
这是我的控制器功能：
$scope.submit = function(credentials) {
var outstanding = ($scope.credentials.amount_payable - $scope.credentials.total_collected);
var base_url = $("meta[name='base_url']").attr('content');
$scope.student_id = ($routeParams.student_id || "");
var data = {
'user_id': $scope.student_id,
'description': $scope.credentials.description,
'duedate': $scope.dt,
'amount_payable': $scope.credentials.amount_payable,
'total_collected': $scope.credentials.total_collected,
'outstanding': outstanding
};
$http({
method: 'post',
url: base_url + '/student/postfees',
data: data
}).
success(function(data, status, headers, config) {
if(data['success']) {
$scope.feedetails.push(data);
} else {
}
}).
error(function(data, status, headers, config) {
$('#error').html('code: ' + status);
$('#alert').fadeIn(1000).removeClass('hide');
});
};
当我提交表单$scope.feedetails更新时，但行中的表数据仍然相同。但是，如果我点击带有test()功能的按钮，该功能位于表格标签内，则数据会动态更新。我已经通过了simillar主题，但这没有帮助。我认为$scope的问题，请有人给我指点。
PS。我试图将数据放在rootScope中，但结果仍然相同。
答案 0 :(得分：0)
实际上问题是$scope中不存在success而您无法尝试从函数中注入，因为在代码中发生了这样的事情：
promise.success = function(fn) {
assertArgFn(fn, 'fn');
promise.then(function(response) {
fn(response.data, response.status, response.headers, config);
});
return promise;
};
特别注意fn(response.data, response.status, response.headers, config);这意味着只会将那些参数传递给您的函数，并且根本没有$scope或$rootScope。
您可以做的一件事是生成一个可以访问$scope并将其注入.success的函数。
一种可能的实现方式是：
$scope.submit = function(credentials) {
var outstanding = ($scope.credentials.amount_payable - $scope.credentials.total_collected);
var base_url = $("meta[name='base_url']").attr('content');
$scope.student_id = ($routeParams.student_id || "");
var data = {
'user_id': $scope.student_id,
'description': $scope.credentials.description,
'duedate': $scope.dt,
'amount_payable': $scope.credentials.amount_payable,
'total_collected': $scope.credentials.total_collected,
'outstanding': outstanding
};
var callback = function(data) {
$scope.feedetails.push(data);
};
$http({
method: 'post',
url: base_url + '/student/postfees',
data: data
})
.success(function(data, status, headers, config) {
if(data['success']) {
callback(data);
} else {
}
})
.error(function(data, status, headers, config) {
$('#error').html('code: ' + status);
$('#alert').fadeIn(1000).removeClass('hide');
});
};
