我是AngularJS入门者。我正在尝试从发送数据:
A页:范列表页面
至
网页B:Van更新页面。
当用户单击货车的更新链接时,我正在调用控制器并在控制器中检索货车详细信息。但是,我无法使用同一控制器将货车详细信息分配给页面B(货车更新页面)...错误"Cannot set property 'vanNumber' of undefined"
*** Page A: Van List ****
<form name="listVanForm" >
<table>
<tr> <td ng-controller="VanUpdateCtrl"><a href="#/van-update" ng-click="prePopulateForm(row.members.vanNumber.value )" class="btn btn-small btn-primary">update</a></td> </tr>
</table>
</form>
*** Page B: Van Update ****
<div class="container">
<h2>Edit Van </h2>
<form name="updateVanForm" novalidate="novalidate" class="form-horizontal" ng-submit="updateCard(formData)">
<div class="control-group">
<label class="control-label" >Van Number:</label>
<div class="controls">
<input type="text" id="vanNumber" ng-model="formData.vanNumber" placeholder=""/>
</div>
</div>
</form>
</div>
*** VanUpdateCtrl **
app.controller('VanUpdateCtrl', ['$scope', 'VanUpdateFactory', '$location',
function ($scope, VanUpdateFactory, $location) {
//callback for ng-init 'populateDD':
$scope.prePopulateForm = function (cardNoParam m) {
alert('cardNo = '+cardNoParam);
$scope.formData.cardNumber=cardNoParam;}
}
So, $scope.formData.cardNumber OR $scope.formData in the destination page is not recognised.
