Restrict additional comments field to accept only 4000 characters

[Pandu3]

Hi Team,

The requirement is to restrict the additional comments(Journal Input - field type) field to accept only 4000 characters on case record. Can anyone please help me how to achieve this requirement. Thanks in advance. I have written onChange client script on case table,

Script:  //testing purpose I'm trying to restrict 4 characters only

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

var v_comments = g_form.getValue('comments');
var count = v_comments.length;
if (count > 5) {
alert("No.of characters " + count);
g_form.setValue('comments', v_comments.substring(0, 4));
}

}

still it is allowing to enter 5th character but the requirement is to stop allowing the 5th character.

Thanks!

HI @Jaspal Singh ,

1)After entering 5th character , If I click on post option the comments are posting - need to restrict this

2) but if I enter 6th character then 5th & 6th characters are deleting and showing 4 characters only in target field.

Thanks!

In that case, you need a Before Insert BR on the sys_journal_field table.

(function executeRule(current, previous /*null when async*/ ) {

    var v_comments = current.comments;
    var count = v_comments.length;
    if (count > 5) {
        gs.addErrorMessage("No.of characters " + count);
        current.comments=v_comments.substring(0, 4);
    }

})(current, previous);
