        setName("");
    }    
    return(

                className="input input__lg"
                name="text"
                autoComplete="off"
                value={name}
                onChange={handleChange}                
            />
            
            <input
                type="checkbox"
                id="todo-0" 
                value={important}
                onChange={handleChangeImportant}                             
            /> Important
            
            <button type = "submit" className="btn btn__primary btn__lg">
                Add
            </button>
        </form>
    );
}

export default Form;

```

Check if name is not empty.检查名称是否不为空。

   function handleSubmit(e){
        e.preventDefault();
        //alert('Moin');
        if(name !==''){
        props.addTask(name);
        setName("");
     }
    }   
function handleSubmit(e) { e.preventDefault(); if (name === '') return; props.addTask(name); setName(''); }
