从 vanilla JavaScript DOM 调用基于 React 函数的组件

Question

我已经使用基于类的组件实现了这一点。 但是在我尝试使用 React Hooks 时希望使用基于函数的组件来获得答案。

核心问题是我想从 JavaScript DOM 中调用一个反应 function 在数据表操作列内的编辑按钮上单击。

我有一个以index.js作为入口点的基于 CRUD 的反应组件。 里面有一个ListPage组件。 但是在反应render/return方法中没有渲染行。 它一直在使用 JavaScipt Datatable 进行渲染。 数据表行有一个按钮来编辑记录。 该按钮的onClick我想更新 React 状态以显示/隐藏编辑表单。

index.js：

import React, { useState } from "react";
import ReactDOM from "react-dom";
import CardWrapper from "../../html/wrappers/Card";
import ListPage from "./ListPage";


const Organization = () => {
    const page = {
        title : "Organization List",
        action: "list"
    } 
    const [state, setState] = useState(page);

    const showEditForm = () => {
        console.log('Edit Organizatioin');

    }

    return(
        <div>
             <CardWrapper title={page.title}>
                 {page.action === 'list' && <ListPage editRecord={showEditForm} />}
             </CardWrapper>
        </div>
    )

};


const domContainer = document.getElementById("react-app");
ReactDOM.render(<Organization 
        ref={(Organization) => { window.Organization = Organization }} 
        />, domContainer);

ListPage.js：

import React, { createRef, useState } from "react";
import Config from "../../../config";
import SearchForm from "../../html/common/SearchForm";

const ListPage = (props) => {

    editRef = createRef(props.editRecord);

    return(
        <div>
            <SearchForm placeholder="keyword" 
                id="kt_datatable_search_query"
                buttonId="kt_datatable_search_submit" 
            />
            <div id="kt_datatable"></div>
        </div>
    )
}

jQuery(function() {

export default ListPage;

现在在上面的代码中，我需要在Actions列的 Edit 按钮点击事件中传递 function 来调用 react function。

解决了

在 ListPage.js 中：下面注释了需要进行的Answer更改。

import React, { useCallback, useEffect, useRef, useState } from "react";
import Config from "../../../config";
import SearchForm from "../../html/common/SearchForm";

const ListPage = (props) => {

    const [editId, setEditId] = useState('');
    
    useEffect(()=>{
        console.log('ListPage Render', editId);
        if(editId){
            props.editRecord(editId);
        }
    }, [editId]);

    return(
        <div>
            <SearchForm placeholder="keyword" 
                id="kt_datatable_search_query"
                buttonId="kt_datatable_search_submit" 
            />
            <input name="editId" type="text" onInput={(e)=>setEditId(e.target.value)} value={editId} />
            <div id="kt_datatable"></div>
        </div>
    )
}

jQuery(function() {
    KTDatatableBasic.init();

    // ====== Answer: Need to fire input event manually =====
    window.updateEditId = function(id) {
        var ev = new Event('input', { bubbles: true});
        // ev.simulated = true;
        $("input[name='editId']").val(id)[0].dispatchEvent(ev);
    }
});

"use strict";
// Class definition
