我正在开发angularjs中的应用程序并使用自动完成功能。
在此应用程序中,在自动填充中选择项目之前,有些字段无法填充。
此表单中有一个字段取决于其他两个字段的结果,如下所示:
此处,Ordem,Tipo de Fluxo,Fluxo Pai和Descrição字段仅在选择UC时才会发布。
有关的领域是Fluxo Pai,其选择因UC和Tipo de Fluxo的响应而异。
我不能简单地询问我用来过滤的WebService,因为它没有这个过滤器,我必须使用javascript。
我正在考虑使用一个事件,当选择UC时,如果选择了Tipo de Fluxo,它将过滤器应用过滤器。
提前致谢
最后,我正在使用的代码。

控制器
app
.controller('flCtrl', function ($rootScope, $scope, $flow, $flowtype, $usecase, $timeout, $q) {
$rootScope.menu = "Cadastro de Flow";
$scope.flow = { id: 0, usercreate: "app.outros" };
// $scope.usecases = loadAll();
$usecase.load(function (usecases) {
$scope.usecases = usecases.result;
}, function (err) {
console.log(err);
});
// console.log($scope.usecases);
$scope.selectedItem = null;
$scope.searchText = null;
$scope.querySearch = querySearch;
$flowtype.load(function (flowtypes) {
$scope.flowtypesVM = flowtypes.result;
}, function (err) {
console.log(err);
});
$flow.load(function (flowsvm) {
$scope.flowsvm = flowsvm;
}, function (err) {
console.log(err);
});
$scope.usecaseflows = [];
$scope.save = function () {
// alert("Olá");
var flow = $scope.flow;
flow.idusecase = $scope.flow.idusecase.Id;
var param = [flow];
$flow.save(param)
.then(function (resolve) {
alert("Ok!");
$scope.flowRegister.$setPristine();
document.flowRegister.reset();
})
.catch(function (reject) {
})
}
function querySearch(query) {
var results = query ? $scope.usecases.filter(createFilterFor(query)) : $scope.usecases;
return results;
}
function createFilterFor(query) {
return function filterFn(usecases) {
return (usecases.Description.indexOf(query) === 0);
};
}
});
答案 0 :(得分:0)
我认为你可以这样做:
app.controller('flCtrl', function ($rootScope, $scope, $flow, $flowtype, $usecase, $timeout, $q) {
...
$scope.$watch('flow', function(){
if(flow.idflowtype && flow.idusecase) {
// call apply filter function here
}
})
})
