autopopulate field depending on another field

[BenjaminY]

Hello,

I am tasked to fix a bug on a client script that when the field "please_provide_a_number" is inputted, the field "a_number" should be auto populated with the same input. I created a client script, but I believe it is not triggering due to Initial script. Should i add a default value on the table to autopopulate the field from the app studio? If so what would be the best way of going about this. Below is scripts:

initial script: 

variable name: please_provide_a_number

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    //Type appropriate comment here, and begin script below

        //Type appropriate comment here, and begin script below

        var recordNum = g_form.getValue('please_provide_a_number');

        var ajax = new GlideAjax('alienNumCCHT');

        ajax.addParam('sysparm_name', 'alienNumCCHT');

        ajax.addParam('sysparm_record_num', recordNum);

        ajax.getXMLAnswer(populateCpRecord);

        function populateCpRecord(response){

            var ans = JSON.parse(response);

            g_form.setValue('extention_victim_last_name', ans.lastName);

            g_form.setValue('extention_victim_first_name', ans.firstName);

            g_form.setValue('extention_victim_middle_name', ans.middleName);

            g_form.setValue('address_line_1', ans.addressOne);

            g_form.setValue('ext_victim_address_line_2', ans.addressTwo);

            g_form.setValue('extention_victim_alies', ans.alias);

            g_form.setValue('ext_victim_city', ans.city);

            g_form.setValue('ext_victim_state', ans.state);

            g_form.setValue('ext_social_security_number', ans.social);

            g_form.setValue('ext_date_of_birth', ans.dob);

            g_form.setValue('ext_country_of_citizenship', ans.coc);

            g_form.setValue('ext_country_of_birth', ans.cob);

            g_form.setValue('ext_gender', ans.gender);

            g_form.setValue('lead_case_last_name', ans.leadLast);

            g_form.setValue('lead_case_email_address', ans.leadEmail);

            g_form.setValue('lead_case_first_name', ans.leadFirst);

            g_form.setValue('lead_case_phone_number', ans.leadNum);

            g_form.setValue('lead_case_middle_name', ans.leadMiddle);

            g_form.setValue('lead_case_ext', ans.leadExt);

            g_form.setValue('wc_ext_last_name', ans.vwLast);

            g_form.setValue('wc_ext_first_name', ans.vwFirst);

            g_form.setValue('wc_ext_middle_name', ans.vwMiddle);

            g_form.setValue('wc_ext_phone_number', ans.vwNum);

            g_form.setValue('wc_ext_email', ans.vwEmail);

            g_form.setValue('vw_ext_officer', ans.vwExt);

            g_form.setValue('ext_case_agent_last_name', ans.mLast);

            g_form.setValue('ext_case_agent_last_name_first_name', ans.mFirst);

            g_form.setValue('ext_case_agent_middle_name', ans.mMiddle);

            g_form.setValue('ext_case_agent_phone_number', ans.mNum);

            g_form.setValue('ext_case_email', ans.mEmail);

            g_form.setValue('ext_lead_case', ans.mExt);

            g_form.setValue('a_number', ans.aNum);

            g_form.setValue('lead_case_agency_office', ans.lea);

            g_form.setValue('ead_expiration_date', ans.exp);

            // alert("CP Record Num is " + ans);

        }

}

second script to check if a_number field has been filled, if not populate...
variable name: please_provide_a_number

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    // Get input from "please_provide_a_number" field

    var numberValue = g_form.getValue('please_provide_a_number');

    // Only populate the "a_number" field if not already populated (to avoid overwriting other client scirpt)

    if (!g_form.getValue('a_number')) {

        g_form.setValue('a_number', numberValue);

    }

My guess, without seeing your Script Include script from your Ajax call, is that you are having a script order issue. You have two onChange client scripts running onChange on the same field. So you don't know which one will run first unless one has a higher order to run later. Can you post a screenshot of your script include method you are calling, the one named ,alienNumCCHT?

Instead of a second onChange script on the same field, just replace the setValue line for 'a_number' in the 'initial script':

if (ans.aNum) {
    g_form.setValue('a_number', ans.aNum);
} else {
    g_form.setValue('a_number', newValue);
}
