HTML5 模式允许特定的特殊字符

Question

I have an input text field in my form but i don't know how to filter the input that can all letters and special characters but will not accept numbers.

   <input  pattern="[A-Za-z]{1,25}" maxlength="25" type="text" required="required" style="height:20px"  value="">

It doesn't accept when i enter my middle name "pacaña"

how could i alter the pattern that can accept all characters/special-characters and other special characters like ñ?

Answer 1

pattern="[^0-9]*"

• […] matches a single character
• ^ anything except the following (when within [] )
• 0-9 digits zero through nine
• * between zero and unlimited times

Answer 2

For Not allowing Specific Symbols (dont allow , or .)

<form>
<input type="text" pattern="[^-,]+" title="'-' is not allowed">
<input type="submit">
</form>

Answer 3

Allow any special symbols : [A-Za-z\\W+]

 <form action="/action_page.php"> <label for="country_code">Special Symbols Not Allowed:</label> <input type="text" pattern="[A-Za-z]{1,25}" title="Special characters are not allowed!"><br><br> <input type="submit"> </form> <br><br> <form action="/action_page.php"> <label for="country_code">Special Symbols Allowed:</label> <input type="text" pattern="[A-Za-z\\W+]{1,25}" title="Special characters are not allowed!"><br><br> <input type="submit"> </form>

Answer 4

我遇到了同样的问题，想要让法语口音进入文本字段......经过一些反复试验，结果你可以使用pattern="^[\\p{L}]${1,25}来允许 ASCII 字母和 Unicode 变体、重音字母和特殊字符。
