Dynamic Action in Apex - Select list to Text field

Question

Hi,
I have two text items. Need to create dynamic action for the following,
1. Order_type - Drop down values having CONSUMER & WHOLESALE.
2. Order_number - Text field
When a user selects CONSUMER, order number should automatically change to '1-' and user can enter only 14 characters (1-236666666666).
When a user selects WHOLESALE, order number should automatically change to '2-' and user can enter only 12 characters (2-2155555555).
Can someone please help to resolve this issue.
Thanks in advance.

Thanks Kiran. Actually ,order number should be disabled. only on selection of  order type, order number should be enabled, how do I do that?can you please help
I can do fire on page load and disable order number .But how do i enable it again on selection of order number
    Let's say '1-' is prefix for Order Number when Order Type is 'CONSUMER' and '2-' is the prefix for Order Number when Order Type is 'WHOLESALE'.
    So a solution to your issue would be:
Go to Page Attributes -> CSS -> Inline CSS and add the following class:
.item_disabled {
  cursor: default;
  opacity: 0.5;
  filter: alpha(opacity=50);
  pointer-events: none;
Create three elements PXX_ORDERNUM_PRE, PXX_ORDERNUM_SUF(as text Items) and PXX_ORDER_NUMBER(as hidden. Set Value Protected -> No).
Arrange the PXX_ORDERNUM_PRE and PXX_ORDERNUM_SUF on one row.
Set the "HTML Form Element Attributes" for PXX_ORDERNUM_PRE to this:
readonly="true"
Set the "HTML Form Element CSS Classes" for PXX_ORDERNUM_PRE to this:
item_disabled
    NOTE : The above two points are to make the PXX_ORDERNUM_PRE element readonly, because if we disable the element we can't assign it a value.
On the change event of PXX_ORDER_TYPE select list create dynamic action to populate PXX_ORDERNUM_PRE (as mentioned earlier)
var ordertype = $('#P11_ORDER_TYPE').val();
if (ordertype === 'CONSUMER') {
  $('#P11_ORDER_NUMBER_PRE').val('1-');
} else if (ordertype === 'WHOLESALE') {
  $('#P11_ORDER_NUMBER_PRE').val('2-');
Create an on-submit computation to concatenate PXX_ORDERNUM_PRE and PXX_ORDERNUM_SUF into PXX_ORDER_NUMBER.
Create validation on PXX_ORDERNUM_SUF, if PXX_ORDER_TYPE is 'CONSUMER' the length should be 12 characters, if 'WHOLESALE' the length should be 10 characters.(excluding 2 characters of prefix).
     So this covers the following:
On change of Order Type, Order Number Prefix should be set.
Order Number Prefix should be not able to be modified, but the rest of Order Number should be able to be entered by user.
Order Number should be of specific length depending upon the Order Type.
     Hope this helps!

Kiran
