Prevent onchange script from running when onsubmit script runs

[chetan17421]

Hi All,

I have written a onchange client script and a onsubmit client script. When onsubmit script is running it is triggering the onchange script. But during onsubmit I dont want to run the onchange script. How can I prevent onchange script from running when onsubmit script runs?

Hi @chetan17421,

In ServiceNow, the behavior you're describing is expected, as the `onSubmit` client script triggers field changes, which, in turn, can invoke the `onChange` client script. To prevent the `onChange` script from running during the `onSubmit` process, you can introduce a mechanism to check and skip the `onChange` logic when it's invoked during the `onSubmit`. Here's how you can approach this:

1. Check for onSubmit flag in onChange script:
- In your `onChange` client script, introduce a check to see if the script is running as part of the `onSubmit` process. You can use a flag or a condition related to the `onSubmit` event.

// onChange client script
function onChange() {
if (!g_form.submitted) {
// Your existing onChange logic here
// ...
}
}

In this example, `g_form.submitted` is a flag that indicates whether the form is in the process of being submitted. If it's `true`, it means the `onSubmit` script is running, and the `onChange` logic is skipped.

2. Set the onSubmit flag in onSubmit script:
- In your `onSubmit` client script, set the flag to indicate that the form is being submitted.

// onSubmit client script
function onSubmit() {
g_form.submitted = true;

// Your existing onSubmit logic here
// ...
}

By setting `g_form.submitted` to `true`, you're signaling to the `onChange` script that it should skip its logic during the `onSubmit` process.

This way, you can control the execution of the `onChange` logic based on whether the form is currently being submitted. Always test your scripts thoroughly to ensure they behave as expected in different scenarios.
