我创建了一个带有类别标签和每个类别复选框的表单,如下所示:

Form to display by category with checkbox

我正在使用axios以以下格式从Google表格获取值:

Sample data from google sheet

用于生成值的脚本:

data() {
    return {
      form: {
        email: "",
        name: "",
        phoneNo: "",
        checked: []
      },

      sports: [],
      arts: [],
      dance: [],
      show: true
    };
  },
  methods: {
    getCcaList() {
      this.axios
        .get(
          "(Google sheet batch get API)"
        )
        .then(response => {
          let cellValues = response.data.valueRanges[0].values;

          // cellValues[0][i] contains values of CCA cell
          // cellValues[1][i] contains values of Category cell
          for (let i = 0; i < cellValues[0].length; i++) {
            if (cellValues[1][i] === "Sports")
              this.sports.push(cellValues[0][i]);
            else if (cellValues[1][i] === "Arts")
              this.arts.push(cellValues[0][i]);
            else if (cellValues[1][i] === "Dance")
              this.dance.push(cellValues[0][i]);
          }
        });
    }

具有vue-bootstrap的HTML设计:

<label for="sports">Sports:</label>
<br />
<b-form-checkbox-group v-model="form.checked" name="sports" :options="sports" stacked buttons></b-form-checkbox-group>
<br />

<label for="dance">Dance:</label>
<br />
<b-form-checkbox-group v-model="form.checked" name="dance" :options="dance" stacked buttons></b-form-checkbox-group>
<br />

<label for="arts">Arts:</label>
<br />
<b-form-checkbox-group v-model="form.checked" name="arts" :options="arts" stacked buttons></b-form-checkbox-group>

如果我决定在工作表中添加或删除类别,是否可以在不创建或删除数组的情况下创建上述格式?

到目前为止,我已经尝试过创建一个字典来存储Google表格中的值,并使用v-for显示类别值。但是,我无法按类别显示俱乐部数组中的每个值。

[
    { category: "Sports", club: ["Basketball", "Soccer", "Archery"] },
    { category: "Dance", club: ["Salsa"] },
    { category: "Arts", club: ["Painting", "Choir", "Band", "Drawing"] },
]

您拥有字典的想法是正确的imo,您只需要更改模板即可。我用示例创建了一个沙箱:

https://codesandbox.io/s/dynamic-checkboxes-v1puy?fontsize=14&module=%2Fsrc%2FApp.vue

基本上你想做的就是拿字典

 categories: [
    { category: "Sports", club: ["Basketball", "Soccer", "Archery"] },
    { category: "Dance", club: ["Salsa"] },
    { category: "Arts", club: ["Painting", "Choir", "Band", "Drawing"] }
  ],

然后使用v-for遍历它

<div v-for="c in categories" :key="c.category">
<label :for="c.category">{{c.category}}:</label>
  <br>
  <b-form-checkbox-group
    :name="c.category"
    v-model="form.checked"
    :options="c.club"
    stacked
    buttons
  ></b-form-checkbox-group>
</div>

这样,无论何时添加新类别,模板都会处理它。
