Conditional mandatory field

[Riya17]

Hi,

I have to make 'justification' mandatory if the 'planned_start_time' is less than 3 hours from the change is requested.  I've tried with business rule, it didn't work.  What is the best way to achieve this.

Thanks

Riya

Think you'll need to use an onChange client script on the planned start date field. You'll need to make an ajax call to the server to do the time calculation and return a true or false, you can then use g_form.setMandatory() to make the justification field mandatory.

Hi,

To meets this:

1. Create a Ajax Client Script.

2. Call on form load and Planed Date change

var end=g_form.getValue('u_planned_start_time');
var start=g_form.getValue('opened_at');
var answer;
var ga=new GlideAjax('GetDateDifference');
ga.addParam('sysparm_name','hours');
ga.addParam('sysparm_start',start);
ga.addParam('sysparm_end',end);
ga.getXMLWait();
answer=ga.getAnswer();
if(answer<3)
g_form.setMandatory('u_justification',true);

thanks

Hope this will help you

Hi Upender,

Could you please copy and paste the client script, I can't see anything from the screenshot.

Thank you
