我正在使用以下脚本来验证表单，并希望能够确保输入器在最后一个字段(金额)上正确输入带小数位的数值。
有人可以帮忙吗？
<script type="text/javascript">
<!--
function validate()
{
if( document.create_invoice.job_no.value == "" )
{
alert( "Please provide a Job No" );
document.create_invoice.job_no.focus() ;
return false;
}
if( document.create_invoice.contact.value == "-1" )
{
alert( "Please provide a Customer Contact" );
return false;
}
if( document.create_invoice.employee.value == "-1" )
{
alert( "Please provide an Employee" );
return false;
}
if( document.create_invoice.invoice_no.value == "" )
{
alert( "Please provide an Invoice No" );
document.create_invoice.invoice_no.focus() ;
return false;
}
if( document.create_invoice.address.value == "" )
{
alert( "Please provide an Address" );
document.create_invoice.address.focus() ;
return false;
}
if( document.create_invoice.amount.value == "" )
{
alert( "Please provide an Amount" );
document.create_invoice.amount.focus() ;
return false;
}
}
//-->
</script>
谢谢，
