(Resolvido) onKeyPess não apaga valor

[jow]

Bom dia tenho um campo em meu formulário q formata um valor para o tipo Currency, porém não me deixa eu apagar o valor caso o mesmo esteja errado ... Como faço para resolver isso ... Abaixo o meu código

<input type="text" size="10" name="textfield32"  onKeyPress="return(currencyFormat(this,'.',',',event))">

[jow]

Consegui essa função na net, que resolve o problema em partes .... O q falta para esse script é só aceitar a digitação de números ....

function FormataValor(id,tammax,teclapres) {
    
if(window.event) { // Internet Explorer
    var tecla = teclapres.keyCode; }
else if(teclapres.which) { // Nestcape / firefox
         var tecla = teclapres.which;
}
    

vr = document.getElementById(id).value;
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( ",", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
tam = vr.length;

if (tam < tammax && tecla != 8){ tam = vr.length + 1; }

if (tecla == 8 ){ tam = tam - 1; }

if ( tecla == 8 || tecla >= 48 && tecla <= 57 || tecla >= 96 && tecla <= 105 ){
if ( tam <= 2 ){
document.getElementById(id).value = vr; }
if ( (tam > 2) && (tam <= 5) ){
document.getElementById(id).value = vr.substr( 0, tam - 2 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 6) && (tam <= 8) ){
document.getElementById(id).value = vr.substr( 0, tam - 5 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 9) && (tam <= 11) ){
document.getElementById(id).value = vr.substr( 0, tam - 8 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 12) && (tam <= 14) ){
document.getElementById(id).value = vr.substr( 0, tam - 11 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 15) && (tam <= 17) ){
document.getElementById(id).value = vr.substr( 0, tam - 14 ) + '.' + vr.substr( tam - 14, 3 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam );}
}
}
</script>

Alguém pode me ajudar a fazer com q esse script aceite apenas números no campo do formulário

i aew jow, bom tenta tipo isso aqui:

if(window.event) { // Internet Explorer
    var tecla = teclapres.keyCode; }
else if(teclapres.which) { // Nestcape / firefox
         var tecla = teclapres.which;
}
//PARTE QUE VERIFICA
if ( tecla == 8 || tecla ==0 )
    return true;
else if ( tecla < 48 || tecla > 57 )
    return false;

vr = document.getElementById(id).value;
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( ",", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
tam = vr.length;

if (tam < tammax && tecla != 8){ tam = vr.length + 1; }

if (tecla == 8 ){ tam = tam - 1; }

if ( tecla == 8 || tecla >= 48 && tecla <= 57 || tecla >= 96 && tecla <= 105 ){
if ( tam <= 2 ){
document.getElementById(id).value = vr; }
if ( (tam > 2) && (tam <= 5) ){
document.getElementById(id).value = vr.substr( 0, tam - 2 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 6) && (tam <= 8) ){
document.getElementById(id).value = vr.substr( 0, tam - 5 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 9) && (tam <= 11) ){
document.getElementById(id).value = vr.substr( 0, tam - 8 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 12) && (tam <= 14) ){
document.getElementById(id).value = vr.substr( 0, tam - 11 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 15) && (tam <= 17) ){
document.getElementById(id).value = vr.substr( 0, tam - 14 ) + '.' + vr.substr( tam - 14, 3 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam );}
}
}

no input você chama tipo assim:

<input type="text" id="campo" onkeypress="return FormataValor( 'campo' , 6 , event )" />

espero que ajude, abraço.

Valeu brother, perfeito meu script ficou assim :::

function FormataValor(id,tammax,teclapres) {
if(window.event) { // Internet Explorer
    var tecla = teclapres.keyCode; }
else if(teclapres.which) { // Nestcape / firefox
         var tecla = teclapres.which;
}
//PARTE QUE VERIFICA
if ( tecla == 8 || tecla ==0 )
    return true;
else if ( tecla < 48 || tecla > 57 )
    return false;

vr = document.getElementById(id).value;
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( "/", "" );
vr = vr.toString().replace( ",", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
vr = vr.toString().replace( ".", "" );
tam = vr.length;

if (tam < tammax && tecla != 8){ tam = vr.length + 1; }

if (tecla == 8 ){ tam = tam - 1; }

if ( tecla == 8 || tecla >= 48 && tecla <= 57 || tecla >= 96 && tecla <= 105 ){
if ( tam <= 2 ){
document.getElementById(id).value = vr; }
if ( (tam > 2) && (tam <= 5) ){
document.getElementById(id).value = vr.substr( 0, tam - 2 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 6) && (tam <= 8) ){
document.getElementById(id).value = vr.substr( 0, tam - 5 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 9) && (tam <= 11) ){
document.getElementById(id).value = vr.substr( 0, tam - 8 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 12) && (tam <= 14) ){
document.getElementById(id).value = vr.substr( 0, tam - 11 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam ); }
if ( (tam >= 15) && (tam <= 17) ){
document.getElementById(id).value = vr.substr( 0, tam - 14 ) + '.' + vr.substr( tam - 14, 3 ) + '.' + vr.substr( tam - 11, 3 ) + '.' + vr.substr( tam - 8, 3 ) + '.' + vr.substr( tam - 5, 3 ) + ',' + vr.substr( tam - 2, tam );}
}
}

pra chamar a função

<input type="text" name="campo" id="campo" onkeypress="return FormataValor(this.id , 10 , event )" maxlength="10" />
