回答by Naftali aka Neal
$(document).keydown(function(objEvent) {
if (objEvent.keyCode == 9) { //tab pressed
objEvent.preventDefault(); // stops its action
}
})

You can do it like this:
你可以这样做：
$(":input, a").attr("tabindex", "-1");
That will disable getting focus with tab in all links and form elements.
这将禁止在所有链接和表单元素中使用选项卡获得焦点。
Hope this helps

On Neal answer, I'd only add:
在尼尔的回答中，我只想补充：
if (objEvent.keyCode == 9) { //tab pressed
return;
}
Because when you finish typing CPF and press TAB, it counts as a character and changes to CNPJ mask.
因为当您完成输入 CPF 并按 TAB 时，它会被视为一个字符并更改为 CNPJ 掩码。
Complete code:
完整代码：
<script type="text/javascript">
$(document).ready(function() {
$("#cpfcnpj").keydown(function(objEvent){
if (objEvent.keyCode == 9) { //tab pressed
return;
}
try {
$("#cpfcnpj").unmask();
} catch (e) {}
var size= $("#cpfcnpj").val().length;
if(size < 11){
$("#cpfcnpj").mask("999.999.999-99");
} else {
$("#cpfcnpj").mask("99.999.999/9999-99");
}
});
});
</script>
