Client script overriding the UI policy and making a field editable

[shany_b]

Hi,

I wrote an onload client script :

function onLoad() {

var isAdmin = g_user.hasRole('admin');

if (isAdmin){

g_form.setReadOnly('u_withdraw_credit_in_advance',false);

g_form.setReadOnly('u_deposit_real_money',false);

} }

but the fields stay readonly.

I saw with the debug that a ui policy occurs after the client script and changes the fields back to readonly.

How can I implement it so it will override the ui policy?

Thank you in advance,

Shany

Hello Shany,

Check out this

Use UI policy instead of a client script

[Rajesh Mushke]

Hello shany ben,

1). Don't use the UI Policy and client script for same field, better to use UI Policy because it is alternate to the client script to make field read only Mandatory and Hidden.

2). Client script:Client scripts are shipped to the client (the browser) and run there instead of on the server. Users who know JavaScript can define scripts to run in the client browser

      UI policy:UI policies offer an alternative to client scripts for dynamically changing information on a form. Administrators and users with the Personalize Rules [personalize_rules] or the UI policy administrator [ui_policy_admin] role can use UI policies to define custom process flows for tasks.

NOTE:As a best practice always use UI policy if you want to make field to be hidden,readonly,Mandatory

3). Basically UI Policy will run whenever condition is met i.e., onLoad and onChange. If you do not want UI Policy to run onLoad, you need to uncheck "On Load"   checkbox.

  Client Scripts runs onLoad, onChange, onSubmit & celledit.
