Hello,
I’m trying to validate an edit called CPF

The validation is working and the edit is filled with “invalid CPF” but the form is submitting the information even with a “return false”

Can you help me?

the function is inside the button’s Onclick()

export function button1_click ( event ) {
let cpf = $w ( ‘#input1’ ). value . replace ( “.” , “” ). replace ( “.” , “” ). replace ( “.” , “” ). replace ( “-” , “” )

// Elimina CPFs invalidos conhecidos 
**if**  ( cpf . length  !=  11  || 
    cpf  ==  "00000000000"  || 
    cpf  ==  "11111111111"  || 
    cpf  ==  "22222222222"  || 
    cpf  ==  "33333333333"  || 
    cpf  ==  "44444444444"  || 
    cpf  ==  "55555555555"  || 
    cpf  ==  "66666666666"  || 
    cpf  ==  "77777777777"  || 
    cpf  ==  "88888888888"  || 
    cpf  ==  "99999999999" ) { 
        $w ( '#input1' ). value  =  "CPF Inválido!" ; 
        **return**  **false** ; 
    } 
// Valida 1o digito  
**let**  add  =  0 ; 
**let**  i 
**for**  ( i  =  0 ;  i  <  9 ;  i ++) 
    add  +=  parseInt ( cpf . charAt ( i )) * ( 10  -  i ); 
**let**  rev  =  11  - ( add  %  11 ); 
**if**  ( rev  ==  10  ||  rev  ==  11 ) 
    rev  =  0 ; 
**if**  ( rev  !=  parseInt ( cpf . charAt ( 9 ))) { 
    $w ( '#input1' ). value  =  "CPF Inválido!" ; 
    **return**  **false** ; 
} 
// Valida 2o digito  
add  =  0 ; 
**for**  ( i  =  0 ;  i  <  10 ;  i ++) 
    add  +=  parseInt ( cpf . charAt ( i )) * ( 11  -  i ); 
rev  =  11  - ( add  %  11 ); 
**if**  ( rev  ==  10  ||  rev  ==  11 ) 
    rev  =  0 ; 
**if**  ( rev  !=  parseInt ( cpf . charAt ( 10 ))) { 
    $w ( '#input1' ). value  =  "CPF Inválido!" ; 
    **return**  **false** ; 
} 
**return**  **true** ;

}

Use $w(‘#input1’).onCustomValdiation((value, reject) => {/here/})
See here . And put it inside the $w.onReady and not inside the button1_click event handler).

(P.S. it’s JavaScript. Java is completely different programming language).
