如何使模糊与跨度元素图标一起使用？

如何解决如何使模糊与跨度元素图标一起使用？

我希望在单击按钮时模糊活动元素。这有时有效，但并非始终如一。注意到我们在 :focus/:hover 使用 CSS 时应用了填充图标。这有助于将图标更改为填充图标，但是当我在按钮单击时应用模糊时，这无法将灰色图标带回来。我确实看到活动元素发生了变化，但仍然使用“填充”图标样式。这可能是由于跨度，我了解到跨度有焦点/模糊问题。有没有办法不继续使用“填充”图标并在模糊时切换到常规图标？

添加 -

// Change to blur() the active focus so that icon shifts to regular and feels like unselected.
            const currentTarget = e.currentTarget as HTMLElement;
            (currentTarget.closest('.ms-Button') as HTMLElement)?.blur();

反应：

export const FilePickerButton: React.FunctionComponent<FilePickerButtonFCProps> = ({
    position,ariaLabel,ariaDescription,disabled,iconName,toolbarButtonId,acceptParams,onClickEvent,...props
}) => {
    const uploadRef = React.useRef<HTMLInputElement>(null);
    const fileUploadRefLink: (e: FluentButtonEventType) => void = React.useCallback(
        (e) => {
            uploadRef.current?.click();

            // Change to blur() the active focus so that icon shifts to regular and feels like unselected.
            const currentTarget = e.currentTarget as HTMLElement;
            (currentTarget.closest('.ms-Button') as HTMLElement)?.blur();
        },[uploadRef]
    );

    const onClick = React.useCallback((e) => {
        // uploading same file again works with clearing up cache
        e.target.value = '';
    },[]);

    return (
        <>
            <input
                type="file"
                ref={uploadRef}
                id={`${toolbarButtonId}`}
                accept={acceptParams}
                onChange={onClickEvent}
                onClick={onClick}
                className="fileUploadPicker"
            />
            <ToolbarButton
                ariaLabel={ariaLabel}
                ariaDescription={ariaDescription}
                disabled={disabled}
                iconName={iconName}
                id={toolbarButtonId}
                position={position}
                onClick={fileUploadRefLink}
                {...props}
            />
        </>
    );
};
