I tried to replace with your suggest coded too but it still doesnt work. I check using inspect element and it shows the id of the price listing field is "sf_field_price" so I changed using the code

<script type="text/javascript">
{literal}
$(document).ready(function(){
$('#sf_field_price').priceFormat({
prefix: '',
thousandsSeparator: ',',
limit: false,
centsLimit: 0,
centsSeparator: ''
});
})
{/literal}
</script>
But it still doesnt work
