Disable CRM Form through JavaScript

I often get the question how to disable a form, so here it is:

The trick is to disable all the fields that are on the form. You can do this by using the following JavaScript:

if (crmForm.FormType == 2)
{
for( var i = 0 ; i < crmForm.all.length ; i++ )
{
if( crmForm.all[ i ].req)
crmForm.all[ i ].Disabled = true;
}
}

In the code I check if the form is in the update modus (FormType == 2), because I don't think that disabling a form while in create modus makes much sense. In the real world you'd probably disable a form depending on the value of another field.

Would you like to keep some fields editable, you can do the following:

if (crmForm.FormType == 2)
{
for( var i = 0 ; i < crmForm.all.length ; i++ )
{
if( crmForm.all[ i ].req && crmForm.all[i].id != "name")
crmForm.all[ i ].Disabled = true;
}
}

Here I disable all fields except the name field (crmForm.all[i].id != "name"). You can add other fields according to your needs. Just make sure you use the schema name of the fields you want to keep enabled.

Happy coding!
