On Change Client script error.

[Lucky1]

Hi all,

I have created an On change Client script on Incident form, on the field 'Severity'.

I have just written alert(cmdb_ci');

So, on change of Severity field, it should show me alert. Right?

But it is showing error like below: 

Please help

Regards,

Lucky

Hi,

If you want to display the value of the cmdb_ci field please try

alert(g_form.getValue('cmdb_ci'));

Hi @Lucky1,

There's a few things going on under the scenes that you may not be aware of.

First, to retrieve a field value in a Client script you need to leverage the g_form API such as g_form.getValue('field_name'). In addition, when you're trying to retrieve a reference field (which CI is), you need a further step as below - g_form.getDisplayBox('field_name').value - see below as to how to use this.

Use the below onChange Client Script.

Thanks, Robbie

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

    var ciDisplayVal = g_form.getDisplayBox('cmdb_ci').value;
    alert('Ci val: ' + ciDisplayVal);

}

Hi @Lucky1,

Can you remove the brackets at the end of the string 'value' as shown below.

It should end with .value;

It should not end with .value() 

It's a subtle difference but make the difference. See my screen shot and initial response again.
