I'm using this currency mask, it works fine even though putting a maxlength
into input
does not limit the number of numbers.
<script language="javascript">
function MascaraMoeda(objTextBox, SeparadorMilesimo, SeparadorDecimal, e){
var sep = 0;
var key = '';
var i = j = 0;
var len = len2 = 0;
var strCheck = '0123456789';
var aux = aux2 = '';
var whichCode = (window.Event) ? e.which : e.keyCode;
if (whichCode == 13 || whichCode == 8) return true;
key = String.fromCharCode(whichCode); // Valor para o código da Chave
if (strCheck.indexOf(key) == -1) return false; // Chave inválida
len = objTextBox.value.length;
for(i = 0; i < len; i++)
if ((objTextBox.value.charAt(i) != '0') && (objTextBox.value.charAt(i) != SeparadorDecimal)) break;
aux = '';
for(; i < len; i++)
if (strCheck.indexOf(objTextBox.value.charAt(i))!=-1) aux += objTextBox.value.charAt(i);
aux += key;
len = aux.length;
if (len == 0) objTextBox.value = '';
if (len == 1) objTextBox.value = '0'+ SeparadorDecimal + '0' + aux;
if (len == 2) objTextBox.value = '0'+ SeparadorDecimal + aux;
if (len > 2) {
aux2 = '';
for (j = 0, i = len - 3; i >= 0; i--) {
if (j == 3) {
aux2 += SeparadorMilesimo;
j = 0;
}
aux2 += aux.charAt(i);
j++;
}
objTextBox.value = '';
len2 = aux2.length;
for (i = len2 - 1; i >= 0; i--)
objTextBox.value += aux2.charAt(i);
objTextBox.value += SeparadorDecimal + aux.substr(len - 2, len);
}
return false;
}
</script>
<input type="text" name="post_price" required="required" class="form-control form-control-md" maxlength="8" onKeyPress="return(MascaraMoeda(this,'.',',',event))" placeholder="<?php esc_html_e('Sale price', 'classiera') ?>">
One more thing (it does not bother much, but I find it annoying), tab does not work when I'm in this field.
