来自REST的JSON / XML
{
litm: "T00000245",
lotn: "00004"
}
<jdeSerials>
<litm>T00000245</litm>
<lotn>00004</lotn>
</jdeSerials>
AngularJS控制器
//Searching a product with serial number/LOTN
$scope.searchProduct = function () {
var lotn = $scope.jdeSerials.lotn;
console.log("searchProduct---->" + lotn);//log-->searchProduct---->00004
$scope.JdeSerials = lotnService.get({id: lotn}, function() {
console.log($scope.jdeSerials);//log-->[object Object]
console.log($scope.jdeSerials.litm);//log-->undefined!!!!!
});
//var litm = $scope.jdeSerials.litm;
//$scope.jdeproduct = productService.get({id: litm});
};
AngularJS服务
angular.module('lotnService', ['ngResource'])
.factory('lotnService', ['$resource',
function ($resource) {
console.log('------lotmService-----');
return $resource(
'http://localhost:8080/RMAServer/webresources/com.pako.entity.jdeserials/:id',
{},
{
update: { method: 'PUT', params: {id: '@lotn'} }
});
}]);
问题
如何获取$ scope.jdeSerials.litm的值?有没有更好的想法解决这个问题,比如创建一个处理这两个GET的服务?我认为原因是GET方法是异步的,但处理这种情况的最佳解决方案是什么?
修改/更新
我改变了这样的服务电话:
$scope.JdeSerials = lotnService.get({id:lotn})
.$promise.then(function(jdeSerials) {
$scope.jdeSerials = jdeSerials;
console.log("1--------------->LITM:"+$scope.jdeSerials.litm);
});
我得到了LITM,但我也得到了错误消息:
TypeError: Cannot read property 'then' of undefined
答案 0 :(得分:1)
尝试在资源中创建一个get方法。
angular.module('lotnService', ['ngResource'])
.factory('lotnService', ['$resource', function ($resource) {
return $resource( 'http://localhost:8080/RMAServer/webresources/com.pako.entity.jdeserials/:id',
{},
{
get: { method: 'GET', params: {id: '@lotn'}},
update: { method: 'PUT', params: {id: '@lotn'} }
});
}]);
然后在你的控制器中,调用方法来自服务:
lotnService.get({id:lotn}).$promise.then(
function(jdeSerials) {
$scope.jdeSerials = jdeSerials;
console.log("1--------------->LITM:"+$scope.jdeSerials.litm);
});
