How to reference parent field in child client script

[Elizabeth26]

I need to reference a parent field on a child client script.

It is not working.

var category = g_form.getValue('x_table_name.parent_case.field_name');

Not getting the statement completely!

Still let me try to answer it, if you want to get parent field in child table client script, please try:

g_form.getValue("NAME_OF_THE_FIELD_IN_PARENT_TABLE");

because that field is the part of child table also!

If it has not answered your query please take a look at THIS

I have tried using as you suggested above - which isn't working.

I have tried the example I put in a different script which does work but not sure why it won't work here.

I am currently looking at that other article.

Hi,

'x_table_name.parent_case.field_name' is not a form field I guess.  You can use GlideAJax in the client script, along with a script include, to get the value.

Have you tried a "getReference" script function yet?

I recently used the following script in an onChange Client Script for when the Category field is changed and it then checks values on the Category record. Actually this one runs two separate getReference lookups on two different tables.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
       return;
    }
 
    if (newValue && g_form.getValue('proposal_type', 2)) {
        checkIfEpic();
    }

    function checkIfEpic() { //* first reference lookup
        g_form.getReference('category', doAlert);
    }
    
    function doAlert(getCat) {
        if (getCat.getValue('parent') == '04982248db357680ec5c3c00ad961962' || getCat.getValue('parent') == '93b2fe57db55b280deda327e9d961997') {
            g_form.setReadOnly('category', true);
            g_form.setReadOnly('template_name', true);
            getDesc();
        }
    }
    
    function getDesc() { //* second reference lookup
        g_form.getReference('std_change_producer', doAlert2);
    }

    function doAlert2(getDesc) {
        g_form.setValue('short_description', getDesc.short_description);
        g_form.setReadOnly('short_description', true);
    }
 }
