In the previous example, the HTML form contains a
select control that allows you to choose a country among several values in a country list. If you configure the
country parameter using the same procedure as for the
dynamicID parameter, NeoLoad will randomly select one of the possible country values and re-inject it.
You could have used a variable listing all the country options to obtain a similar behavior by setting the parameter value field to a variable. However, by using data extraction, you avoid having to keep variables synchronized with your application. Also, if other country options are added, you do not have to change the configuration or definition.
For more information about the various options and panes, see Submit a form from the previous request<in_pdf_design>.
