You can access the current URL parameters via this.param and it returns a PHP array.
This example demonstrates how to access the tab URL parameter in a page.
url = "/account/:tab"{% if this.param.tab == 'details' %}
<p>Here are all your details</p>
{% elseif this.param.tab == 'history' %}
<p>You are viewing a blast from the past</p>
{% endif %}If the parameter name is also a variable, then array syntax can be used.
url = "/account/:post_id"{% set name = 'post_id' %}
<p>The post ID is: {{ this.param[name] }}</p>
