需要帮助。我对Vue.js相当陌生,需要一些帮助和建议。
背景:
我有一个内部带有BS模式的组件,它在for循环中呈现,显然有很多示例。
发布日期:
The very first rendered component has its data received from parent via props, and the rest component have their own (like row.id and etc.)
问题:怎么解决?可能是BS模式的问题?
组成部分:

let vSelect = Vue.component("v-select", VueSelect.VueSelect);

    var scoringButton = Vue.component("scoring-button", {
      props: ["loadId", "causeData"],
      template: "#scoring-template",
      components: {
        "v-select": vSelect,
      },
      data: function () {
        return {
          scoredLoadId: this.loadId,
          scoring: null,
          causeId: null,
          selectedCause: null,
          causeList: this.causeData,
        };
      },
      computed: {
        showCauseList() {
          if (this.scoring === "1" || this.scoring === null) {
            return true;
          }
          return false;
        },
      },
    });

模板:

<template v-cloak id="scoring-template">
      <div class="scoring-block" :id="scoredLoadId">
        <div class="scoring">
          <button

母公司:

var mainTableApp = new Vue({
        el: "#main-table",
        data: {
            tableData: [],
            scoringCauseList: [
                 {
                   "id": 6,
                   "scoring_type": 0,
                   "name": "Late at loading",
                   "mark": "late_at_loading"
                 },
                 {
                   "id": 7,
                   "scoring_type": 0,
                   "name": "Special conditions were not respected",
                   "mark": "special_conditions_were_not_respected"
                 },
                 {
                   "id": 8,
                   "scoring_type": 0,
                    "name": "Bad/not enough information",
                   "mark": "bad_not_enough_information"
                  }
              ],
        },
        components:{
            'scoring-button': scoringButton,
        }
    });

主应用程序块中的组件:

<div 
   v-for="row in tableData"
   class="row-container"
   >
   ....
   <scoring-button 
      :id="row.LOAD_ID"
      :key="row.LOAD_ID"
      :load-id="row.LOAD_ID" 
      :cause-data="scoringCauseList"
   >
   </scoring-button>
   ....
</div>

我试着重新设置BS modal的数据,但是没有成功。所以,我回去在Vue部分寻找解决方案。
我知道我可能构造整个事情不够在一个非常正确的方式,但下面的代码是最后一个版本后,许多其他的解决方案,已尝试与v模型,$emit, prop 等。

更新:找到解决方案。
为组件中的所有“input”字段添加了“:id”。
因此,要让可重用组件拥有自己的数据属性,你需要有动态的“:id”属性,这样,每个数据都流入自己的组件。

<input
        type="radio"
        class="btn-check"
        name="btnScore"
        id="btnLike"    // <-- old line
        :id="`btnLike-${dynamicStr}`" // <-- new modified line
        autocomplete="off"
        checked="scoring === '1'"
        value="1"
        v-model="scoring"
      />
      <label
        class="btn btn-outline-success"
        for="btnLike" // <-- old line
       :for="'btnLike-${dynamicStr}'" // <-- new modified line
        @click="clearSelectedCause"
      >
   <i class="bi bi-hand-thumbs-up-fill"></i> Like
   </label>
