Certainly! To achieve this behavior, you can use a client script in ServiceNow. Here's the client script code that you can use to handle the onChange and onLoad events for the "agreement" field:
function onLoad() {
checkAgreement();
}
function onChange(control, oldValue, newValue, isLoading) {
if (!isLoading) {
checkAgreement();
}
}
function checkAgreement() {
var agreementField = g_form.getControl('agreement');
var agreementValue = agreementField.value;
var message1 = g_form.getMessages('message1');
var message2 = g_form.getMessages('message2');
if (agreementValue === 'none') {
if (message1.length === 0) {
g_form.addInfoMessage('message1');
}
if (message2.length > 0) {
g_form.removeMessage('message2');
}
} else if (agreementValue === 'yes') {
if (message2.length === 0) {
g_form.addInfoMessage('message2');
}
if (message1.length > 0) {
g_form.removeMessage('message1');
}
} else if (agreementValue === 'no') {
// If 'no' is chosen, no message is shown
if (message1.length > 0) {
g_form.removeMessage('message1');
}
if (message2.length > 0) {
g_form.removeMessage('message2');
}
}
}
In this script:
- The `onLoad` function is triggered when the form is loaded.
- The `onChange` function is triggered whenever the "agreement" field value changes.
- The `checkAgreement` function checks the value of the "agreement" field and shows/removes messages accordingly.
Make sure to replace `'agreement'` with the actual name of your field in ServiceNow. Also, replace `'message1'` and `'message2'` with the actual names of your sys_ui_message records.
This script should cover the behavior you described: showing specific messages based on the selected value of the "agreement" field. Remember to test the script thoroughly in your ServiceNow instance to ensure it behaves as expected.
