如何知道多次调用视图？

Question

I'm using laravel 5.2. In a current view, how can I know if this view is called before? Any suggestions?

Update:

Here's the scenario, I have a script in a view, and I want to run it once: the first time the view got called.

Answer 1

Ok, I managed to solved this by myself. This javascript code will run once the first time the view got called:

@if (! $__env->yieldContent('some_section_script'))
    @section ('some_section_script')
        <script type="text/javascript">
            console.log('Hello world');
        </script>
    @stop

    @yield('some_section_script')
@endif
