Question

With the following knockout.js code, I’d like to set a flag within an inner loop and then use the flag outside of the loop. What’s the best way to do this?

<!-- there is an ASP.NET outer loop here -->

<!-- initialize variable 'myFlag = true' here -->
<div data-bind="foreach: jobs">                             
  <!-- ko if: industry == 'tech' --> 
    <!-- set myFlag to false here -->
    <!-- display job info here -->
  <!-- /ko -->                

  <!-- ko if: myFlag == true -->
    <!-- display 'no jobs for industry' message here -->
  <!-- /ko -->
</div>   

<!-- end outer ASP.NET outer loop -->

You can try the afterRender property of the foreach binding:

<div data-bind="foreach: { data: jobs, afterRender: doSomething }">

This will call doSomething for each iteration of jobs.
