我想编辑一个现有的块来添加另存为元数据的检查器控件。我一直在绞尽脑汁寻找如何保存数据。以下代码向inspector系统添加了一个文本字段。我可以添加该字段，但由于某些原因，该字段无法保存。我一辈子都想不出来。

var el = wp.element.createElement,
    Fragment = wp.element.Fragment
    registerBlockType = wp.blocks.registerBlockType,
    RichText = wp.editor.RichText,
    BlockControls = wp.editor.BlockControls,
    AlignmentToolbar = wp.editor.AlignmentToolbar,
    Fields = wp.components;

var withInspectorControlsEdit = wp.compose.createHigherOrderComponent( function( BlockEdit ) {
    return function( props ) {
        return el(
            wp.element.Fragment,
            {},
            el( BlockEdit, props ),
            el(
                wp.editor.InspectorControls,
                {},
                el(
                    Fields.PanelBody,
                    {},
                    el(
                        Fields.TextControl,
                        {
                            label: \'Test Field\',
                            value: props.attributes.testField,
                            onChange: function(e){
                                props.setAttributes({ testField: e });
                            }
                        }
                    )
                )   
            )
        )
    };
}, \'withInspectorControlsEdit\' );
wp.hooks.addFilter( \'editor.BlockEdit\', \'acf/accordion\', withInspectorControlsEdit );
