Match/Case Else?

How-to Discussions

Hi,

I am working on some code that “gets” the first item in an Each loop and prints a special UI for it, using <Each Items="{downloadItems}"><Match Items="{index}"><Case Number="0"> ... </Case></Match></Each>.

However for all the other items in the Each loop I would like to print a different UI. How can I “else” this Match/Case block?

Something equivalent to the code below, but in UX?:

if (index == 1)
{
    printSpecialUI();
}
else
{
    printRegularUI();
}

Match/Case would be like the switch statement so:

<Each>
  <Match Value="{index}">
    <Case Number="0">
      // special ui
    </Case>
    <Case Number="1">
      // special ui
    </Case>
  </Match>
</Each>

Actually I just figured it out. You can use any other value and set it as the default, so if no other matches are found it will fall in that case.

<Case Number="0"> ... </Case>
<Case Number="100" IsDefault="true"> ... </Case>

Thanks!

Interesting I see its just like switch statements then where you have default::


switch(someVal) {
  case 1:
      doSomething();
  case 2:
      doSomethingElse();
  default:
      doDefault();
}
