in the input password box on the oppoR9s phone, how to restrict input to alphanumeric values,
<input type="number" pattern="[0-9]*" oninput="if(value.length > 11)value = value.slice(0, 11)" placeholder="()">
at present, other mobile phones can be used like this, but oppo phones can"t. Which boss knows the solution? thank you very much
.use this maxlength attribute to try < input type= "number" maxlength= "5" placeholder= "Please enter your mobile phone number (which will be used as a login account)" >
finally use watch to monitor
