我想开发一个自定义块，让用户从自动完成中选择一些信息 . 我设法在编辑功能上创建自动完成组件 .

用户可以选择项目，但我不知道如何处理属性保存 .

我正在尝试将所选项目保存为属性package_name . 我在Autocomplete组件上创建了onChange函数，但是event.target.value是未定义的 .

这是我在block.js中的代码

const { __ } = wp.i18n; // Import __() from wp.i18n
const {  AlignmentToolbar,
        BlockControls,
        registerBlockType } = wp.blocks; 
const { RichText } = wp.editor;
const { Autocomplete, } =wp.components;


const MyAutocomplete = () => {
    const autocompleters = [
        {
            name: 'fruit',   
            triggerPrefix: '@',   
            options: [
                {  name: 'Apple', id: 1 },
                {  name: 'Orange', id: 2 },
                {  name: 'Grapes', id: 3 },
                {  name: 'test', id: 4 },
            ],

            getOptionLabel: option => (
                <span>
                  { option.name }
                </span>
            ),

            getOptionKeywords: option => [ option.name ],

            isOptionDisabled: option => option.name === 'Grapes',

            getOptionCompletion: option => (
                <abbr title={ option.name }>{ option.name }</abbr>
            ),
        }
    ];

    function onChangeAuto(newContent){
        console.log('autocompletexx '+newContent);
    }

    function onSelectAuto(event){
        console.log(event.target);
           console.log( event.target.value);
    }

    return (
        <div>
            <Autocomplete completers={ autocompleters }>
                { ( { isExpanded, listBoxId, activeId } ) => (
                    <div
                        contentEditable
                        suppressContentEditableWarning
                        aria-autocomplete="list"
                        aria-expanded={ isExpanded }
                        aria-owns={ listBoxId }
                        aria-activedescendant={ activeId }
                        onChange={onChangeAuto }
                        onSelect={onSelectAuto}

                    >
                    </div>
                ) }
            </Autocomplete>
            <p class="autocomplete_p">Type @ for triggering the autocomplete.</p>
        </div>
    );
};

    title: __( 'Residence - Membership Package Settings' ), // Block title.

            package_name:{

    edit: function( props ) {

                const { attributes: {package_name}, className,setAttributes,isSelected } = props;

    save: function( props ) {
