Need to restrict entering alphabets and special characters in a textbox using jquery. Need to enter only numbers. How to implement using keypress() functionality in jquery for a text box in jsf?.
Code :
<table>
<tr>
<h:inputlabel value="Actual"></h:inputlabel>
<td>
<h:inputtext id="Actual" styleClass="input-tex" value="#bean.customer"></h:inputtext>
<td>
</tr>
<table>
Any help is appreciated.
you can try this in onkeypress function
function validateDigits(){
var str = "54665";
var re = /^\d+$/;
alert(str.match(re)!=null);
}
it returns true in case it validate successfully otherwise returns false
I'm sure there's a more elegant way, but I use:
$('#parentobject').on('keypress', '#inputid', function (e) {
if (isNaN(e.currentTarget.value) == true) {
var textlen = $(this).val().length;
$(this).val($(this).val().substring(0, (textlen - 1)));
return false;
}
});
