Как я могу иметь возможность выбирать и передавать данные в данном формате в vue js html?

Мне нужно передать данные в данном формате.

rules : [{
        name:null,
        section:null,
        data   : [{head:null,value:null}]
    }],

Это проблема, с которой я столкнулся. Надеюсь, кто-нибудь может помочь мне разобраться в решении. Откроется фрагмент. Мне нужно передать данные в формате, указанном выше. Если в правилах [] используется другой массив, это также отлично

Требуется еще один массив для заголовка и значения внутри данных []. Это также будет прекрасно, если это необходимо. Надеюсь на помощь. Пожалуйста, помогите мне найти решение.

Ответ 1

Мой подход в основном изменяет тип data[0].head и data[0].value зависимости от выбранных вами опций.

Так, например, если вы выберете Rule,2012, тогда data[0].head будут object с item и qty качестве его элементов. И если вы выберете Act,1961, data[0].head будет array чисел (например, ['1', '2']), а data[0].value будет object с area_1 и area_2 или number и model или все четыре элемента.

Смотрите и попробуйте фрагмент кода, чтобы увидеть код, который я добавил/изменил.

(Или сравните свой код с моим, и вы увидите изменения.)

Мое мнение,

  1. На основе HTML, который вы указали, создайте одно свойство data = ruleTemplate (это гарантирует, что v-модель со связанными формами управления).

  2. Когда вы добавляете новые правила, подталкивайте один клон шаблона к правилам

  3. Когда вам нужны данные, просто преобразуйте правила в конкретный формат, например this.getFormattedRules в демо.

Ниже приведена демонстрация:

addForm = new Vue({
      el: "#addForm",
      data: {
        ruleTemplates: {
          name: '',
          section: '',
