她是 HTML 代码

<ion-content>
  <div class="content no-header">
    <ion-nav-bar class="bar-assertive-900" align-title="left">

我想做的是更新审阅者的标题，问题和选择只用一个功能或 view.I 中的一个按钮不希望每个项目都有按钮所以有办法怎么做？谢谢 :D

这是服务文件

service.update = function (rv_id,qs_id,chs_id, rv_object,qs_object,chs_object) {
        // return $http.put(getUrlForId(id), object);

        // for updating rev object
        return $http.put(getRevUrlForId(rv_id), rv_object)
            .then(function (result) {
                console.log(result.data);
            });
        // for updating qstn object
        return $http.put(getQsUrlForId(qs_id), qs_object)
            .then(function (result) {
                    console.log(result.data);
                });
        // for updating chs object
        return $http.put(getChoicesUrlForId(chs_id), chs_object)
            .then(function (result) {
                console.log(result.data);
            });
    };

这是控制器

.controller('EditRevCtrl', function($scope, $timeout, $stateParams, $ionicPopup, ionicMaterialInk, ItemsModel, Backand) { var edtRv = 这个；

edtRv.e = ItemsModel.getcontForEdit(); // use for getting reviewers info

function edit (rv_id,qs_id,chs_id, rv_object,qs_object,chs_object) {
  ItemsModel.update(rv_id,qs_id,chs_id, rv_object,qs_object,chs_object);
}
})

Answer 1

当然可以！

首先，您应该将 $q 注入到您的服务中，因为我们将在下面使用它。使用 Q 你可以传递一系列要解决的承诺。

service.update = function (rv_id,qs_id,chs_id, rv_object,qs_object,chs_object) {
    return $q.all([
        $http.put(getUrlForId(id), object),
        $http.put(getRevUrlForId(rv_id), rv_object),
        $http.put(getQsUrlForId(qs_id), qs_object),
        $http.put(getChoicesUrlForId(chs_id), chs_object),
    ]).then(function(results) {
        var UrlForId = results[0];
        var RevUrlForId = results[1];
        var QsUrlForId= results[2];
        var ChoicesUrlForId= results[3];

        return results;
    })
};

是否可以仅使用一个功能和一个按钮使用 angularjs 更新多个 json object？

Is it possible to update multiple json object using just one function and one button using angularjs?

angularjs

ionic-framework

backand
