I'm developing an online exam application.The questions contain just text or equations or both text and equations. The equations are displayed using Mathjax.There is a timer on the page. I want to start the timer only when the Mathjax equations are loaded completely.If the question doesn't contains any equation then the timer has to be started without waiting for Mathjax.How can this be done? The application is developed in PHP.
