check string interpolation is empty or not in vuejs

Question

I want to check if the value is empty or not.

Paid :  <h6 v-for="pai in PaidAmount">
             <b v-if="pai.billno==report.bill_no" >
             {{pai.paid + report.paid}}</b>                                       
         </h6>

if {{pai.paid + report.paid}} is empty then i want to print only {{report.paid}}

pai.paid + report.paid == '' ? report.paid : 'something else' — Wild Beard

I you are always going to display the report.paid, wouldn't the test really just be if pai.paid is empty? — Taplar

if {{pai.paid + report.paid}} is empty then {{report.paid}} has to be empty as well - what do you want to print ? — birdspider

Check this

   <h6 v-for="pai in PaidAmount">
                 <b v-if="pai.billno==report.bill_no" >
                 {{ (pai.paid + report.paid) ? (pai.paid + report.paid) : report.paid  }}
                 </b>            
             </h6>
