catalog client script to prevent the submission of the catalog form.

[phr]

Hi All,

I have a requirement when the below option is selected i need to present the error message on the catalog item that should present the user from submitting it.

Below is the script that i wrote:-

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var sn = g_form.getValue("do_you_already_have_visual_studio_license");
if (newValue == "no" || sn == 'no') {

g_form.addErrorMessage("Please add GitHub Enterprise license to the service required field in this form");("Please add GitHub Enterprise license to the service required field in this form");
}
}

Its throwing the error message . But i am able to submit the catalog item. 

How to prevent the submission of the catalog item when the error message is presented.

How to achieve this?

(Note: I did use the OnSubmit as well, still i am able to submit the form)

To achieve this requirement please use the on submit client script. 
Check the variable and add the error message 

var sn = g_form.getValue("do_you_already_have_visual_studio_license");

    // alert(sn);

    if (sn == "no") {

        g_form.addErrorMessage(getMessage("Please add GitHub Enterprise license to the service required field in this form"));

        return false;

    } else {

        return true;

    }
