I have got a task to prevent keypress two digits after a decimal number. My jquery file is
$(function(){
$('#name').bind('paste', function(){
var self = this;
setTimeout(function() {
if(!/^[a-zA-Z]+$/.test($(self).val()))
$(self).val('');
}, 0);
});
$('#salary').bind('paste', function(){
var self = this;
setTimeout(function() {
if(!/^d*(.d{1,2})+$/.test($(self).val()))
$(self).val('');
}, 0);
});
$('.decimal').keyup(function(){
var val = $(this).val();
if(isNaN(val)){
val = val.replace(/[^0-9]./g,'');
if(val.split('.').length>2)
val =val.replace(/.+$/,"");
}
$(this).val(val);
});
});
My html page is
<b>Name</b>
<input type="text" id="name" /><br/>
<b>Salary</b>
<input type="text" id="salary" class="decimal" />
here i want only write 2 digits after decimal,how can i do this? You can see my code in http://jsfiddle.net/V6s4B/
