z555sb888（）（）x666返回true（两个空格）
匹配字符串必须是字母+数字

Answer 1

将字符串按照空格进行拆分，对每一段进行校验即可，只要其中一个不满足，那么整段字符串就不满足要求functionhasLetterAndNum(str){returnstr.split(/\s+/).every(item=>/^(?=.*?[0-9])(?=.*?[a-z])[0-9a-z]+$/.test(item))}测试：hasLetterAndNum('qwerty')//falsehasLetterAndNum('123456')//falsehasLetterAndNum('qwe123')//truehasLetterAndNum('qwe123qweabc46')//falsehasLetterAndNum('qwe1235566abc46')//falsehasLetterAndNum('qwe1235566cabc46')//truehasLetterAndNum('qwe1235566cabc46')//true
