scripts to check variable is empty or not

[TMKAM]

I have create 2 variable as per below

variable A = multiline text

variable B - attachment

the above variable is not set as mandatory field and I would like to create a on submit scripts to check base on the below scenario

Scenario 1

Variable A = empty

Variable B = empty meaning no attachment

the script should alert with message when requester press order now button

Scenario 2

Variable A = not empty

Variable B = empty meaning no attachment

the script is not alert with message and requester can press order now button

Scenario 3

Variable A = empty

Variable B = not empty meaning got attachment inside

the script is not alert with message and requester can press order now button

thank you

Hi @TMKAM ,

You can create onSubmit client script with script as below:

function onSubmit() {
    var itemA = g_form.getValue('variable_a');
    var itemB = g_form.getValue('variable_b');
    if (!itemA && !itemB) {
        g_form.addErrorMessage('Please fill out both variables');
        return false;
    }
}

Hi there,

The script above only prevent submitting when both are empty. Can I have the screenshot of your script? and also is there any other onSubmit client script run along with it?
