使用JS來判斷字串裡是否含有大寫字母或小寫字母。

//判斷是否含有大寫字母
function chkhascapitalletter(str)
{
var result = str.match(/^.*[A-Z]+.*$/);
if(result==null) return false;
return true;
}

//判斷是否含有小寫字母
function chkhaslowercaseletters(str)
{
var result = str.match(/^.*[a-z]+.*$/);
if(result==null) return false;
return true;
}

以上紀錄~
