To help avoid end-user confusion, I want to add an alert message that pops up if/when the user clicks any other key ["alert('Only Numerical data allowed')"]. So if they press the 'k' the above message will pop up. Can anyone see how to set this code within this code base
jquery :
$('input.numberinput').bind('keypress', function (e) {
var w = e.which;
return (w != 8 && w != 0 && (w < 48 || w > 57) && w != 46) ? false : true;
});
html
<div class="containercontent">
<div class="label">Enter a number:</div>
<input type="text" name="txtNumber1" id="txtNumber1" value="" class="numberinput" />
<div class="label">Enter a number:</div>
<input type="text" name="txtNumber2" id="txtNumber2" value="" class="numberinput" />
</div>
Simple :
$(document).ready(function () {
$('input.numberinput').bind('keypress', function (e) {
if((e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57) && e.which != 46) )
{
alert('Only Numbers');
return false;
}
else{
return true;
}
});
});
Hello again :) I can help you out with this as well:
$(document).ready(function () {
$('input.numberinput').bind('keypress', function (e) {
var allow = (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57) && e.which != 46) ? false : true;
if (!allow) {
alert('Only Numerical data allowed');
}
return allow;
});
});?
