  8. Within that we defined json array ‘jsarr’ with three properties ‘{"Name":"Prawin","Age":25,"City":"Kangayam"}’. To parse json array we specified ‘jsarr’ with each() loop.
  9. Now you can iterates json array values, in each loop ‘ind-pointing index value, item-pointing iteration value’. There we displaying first property ‘Name’ value by appending variable ‘item’ with array property ‘Name’.
  10. In html block we defined button element ‘Display’ with attribute ‘class’ respective value ‘btn’ and h4 for display final result.
