I need you to only receive values with this formatting (20.00)
Resolved
<!-- apenas números-->
<script>
function somenteNumeros(num) {
var er = /[^0-9.]/;
er.lastIndex = 0;
var campo = num;
if (er.test(campo.value)) {
campo.value = "";
}
}
</script>
<input class="form-control input-sm" onkeyup="somenteNumeros(this);" placeholder="valor" maxlength="5" type="text" ng-model="numero.valor" />
The expression to validate this formatting is /\d*(\.\d\d)$/
Try something like this:
function somenteNumeros() {
var er = /\d*(\.\d\d)$/;
var valCampo = document.getElementById('campo').value;
if (!er.test(valCampo)) {
document.getElementById('campo').value='';
}
}
To allow only numbers, you can do something like this:
add a function similar to this:
function apenasNum(){
var kc = event.keyCode;
if(kc >= 48 && kc <= 57){
return true;
}else{
return false;
}
}
In the form field you add the onKeypress event by calling the function you created:
<input type="text" onKeypress="return apenasNum();">
