Question

I want to write ternary conditional operator in jquery where condition set by jquery variable. My script toggle's class for particular condition only.In my script variable comes from other settings.

jquery:

<script type="text/javascript">
$(document).ready(function() {
  $("#my_div")
    .removeClass("horizontal vertical")
    .addClass( my_color == 'red'  ? 'horizontal' : 'vertical');
});
</script>

my_color is jquery variable which may have one value at a time from red,green,blue,black,white or silver .

I want to set class horizontal if my_color is red, blue or green and class vertical for other three values. can anyone help me write simplified ternary operator for above jquery?

Answer 1

Use or operator in the condition part of the operator. You your would be

<script type="text/javascript">
  $(document).ready(function() {
    $("#my_div")
        .removeClass("horizontal vertical")
        .addClass( my_color == 'red' ||  my_color == 'blue' ||  my_color == 'green'  ? 'horizontal' : 'vertical');
  });
</script>
 $("#my_div")

If you have many color you can put them array and use that in condition.

 $("#my_div")
 .removeClass("horizontal vertical")
 .addClass( ['red', 'blue', 'green', 'gray'].indexOf(my_color) != -1 ? 'horizontal' : 'vertical');
