既然@WebElaine没有指定js方式,我将自己添加它。要添加的完整代码如下:
function setBlockCustomClassName( className, blockName ) {
    return blockName === \'gutenberg-examples/example-03-editable-esnext\' ? //this is the block identifier, taken from the registerBlockType
        \'new class name\' :  //this is class name we want to associate by default to the block, in my case it\'s an empty string since I don\'t want any class 
        className;
}
wp.hooks.addFilter(
    \'blocks.getBlockDefaultClassName\',
    \'gutenberg-examples/example-03-editable-esnext\', //this is again the block identifier, taken from the registerBlockType
    setBlockCustomClassName
);
 总而言之,完整代码是:
registerBlockType( \'gutenberg-examples/example-03-editable-esnext\', {
    title: __( \'Example: Editable (ESNext)\', \'gutenberg-examples\' ),
    icon: \'universal-access-alt\',
    category: \'layout\',
    attributes: {
        content: {
            type: \'array\',
            source: \'children\',
            selector: \'p\',
        },
    },
    edit: ( props ) => {
        const { attributes: { content }, setAttributes, className } = props;
        const onChangeContent = ( newContent ) => {
            setAttributes( { content: newContent } );
        };
        return (
            <RichText
                tagName="p"
                className={ className }
                onChange={ onChangeContent }
                value={ content }
            />
        );
    },
    save: ( props ) => {
        return <RichText.Content tagName="p" value={ props.attributes.content } />;
    },
});
//Old code ended here
function setBlockCustomClassName( className, blockName ) {
    return blockName === \'gutenberg-examples/example-03-editable-esnext\' ? //this is the block identifier, taken from the registerBlockType
        \'new class name\' :  //this is class name we want to associate by default to the block, in my case it\'s an empty string since I don\'t want any class 
        className;
}
wp.hooks.addFilter(
    \'blocks.getBlockDefaultClassName\',
    \'gutenberg-examples/example-03-editable-esnext\', //this is again the block identifier, taken from the registerBlockType
    setBlockCustomClassName
);
 对于一个简单的块,所有这些内容都会进入主js文件(通常是
index.js) 与插件关联。
