验证车牌号码是否有效
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
- 第一個字符必須為漢字，省區(qū)市簡寫；
- 第二個字符為英文字母；
- 第三個字符為分隔符“-”；
- 四到八位為數字和字母的結合；
- 驗證車牌號碼的正則表達式為：
- //驗證普通的車牌號碼 ： 吉A-E1234,吉A-EE123,吉A-12345,吉A-6A123var regExpression1 = /^[\u4e00-\u9fa5][a-zA-Z]-[0-9A-Za-z]{3}\d{2}$/;//驗證車牌號尾號為字母的表達式 var regExpression2 = /^[\u4e00-\u9fa5][a-zA-Z]-\d{4}[a-zA-Z]$/;
