如何用項目符號顯示此字符串？

下面是字符串：

if (!this.value || this.value.length < 5) { 
    alertValidation += "\nYou have not entered a valid Question\n"; 
} 

Answer 1

如果你想alert()它，這樣做：

alertValidation += "\n\u2022 You have not entered a valid Question\n"; 

Answer 2

alert ('\u2022 A, \n\u2022 B, \n\u2022 C, \n\u2022 D');
