javascript - LWC - Javascript 对象不与 Wrapper 类对象反应

Question

您能否指导我如何使包装类对象在 LWC js 中具有反应性。

我相信@track 属性是反应性的，但是当我更改this.coreAttributesjs 对象中任何属性的值时，它不会反映在Save按钮单击中

Js、Apex、Html文件如下

    import { LightningElement, track, api } from "lwc";
    import queryCoreAttributes from "@salesforce/apex/P1PlantInfoPromptSolar.queryCoreAttributes";

    export default class P1PlantInfoPromptSolar extends LightningElement {
    @track coreAttributes;

    connectedCallback() {
        queryCoreAttributes()
        .then(result => {
          this.coreAttributes = JSON.parse(result);
        }) 
        .catch({

        });

        this.promptSpecificAttributes = {
          noOfBlocks:"",
          flatHierarchy:false,
          drivePlus:false
        };
      }
    saveP1PlantInfoPromptMetadataHandler(){
        console.log(' prompt specific att -> '+ JSON.stringify(this.coreAttributes));
      }
    }```

    **HTML file**
    ```<template for:each={coreAttributes} for:item="coreAttribute">
                  <tr key={coreAttribute.key}>
                    <th>{coreAttribute.attributeHeader}</th>
                    <td>
                      <template if:false={coreAttribute.isPicklist}>
                        <input type={coreAttribute.attributeDataType} name={coreAttribute.attributeHeader}
                         value={coreAttribute.attributeValue}/>
                      </template>
                      <template if:true={coreAttribute.isPicklist}>
                        <select size="1" name={coreAttribute.attributeHeader}>
                          <option value="None">--None--</option>
                          <template for:each={coreAttribute.picklistValues} for:item="attributePickValues">
