How to prevent a form from being submitted in an onsubmit client script with a getXML() function?

[Johannes Mweli]

Hi ServiceNow Community Developers

I have the following use case: I am in a scoped application. I am using the onsubmit client script that has the getXML() function. There are fields on the form that I am submitting that needs to be populated by the response of the getXML() function before the form can be submitted. The issue I am running into though is that since getXML() is async it does not wait for the response to come back from the server, it issues a call to the server and then goes ahead and submit the form before the response comes back. As a result of this behavior some fields are submitted without getting populated.

Would you guys please advise if there is a way I can overcome this. In other words is there a way to pause the form submission until the fields that needs to populated by the response  from getXML() function have been populated.

Kindly advise please

Thanks,

Johannes

Hi @Johannes Mweli 

You can use getXMLWait() so that all fields get populated from the server. If you still want to use getXML() then you can put a condition that if required fields that needed to be populated form server if empty then use 'return false' to prevent the form submission.

Hi Sourabh,

getXMLWait() does not work in a scoped application, that's why I am using getXML().

Thanks,

@Johannes Mweli  SN has created a support article explaining this and how to make async call in onsubmit

NOTE: This does not work in catalog client script, as per my discussion with HI support.
