iPad and iPhone – Installing ChatJax Bookmark

bookmarksiosipadiphonesafari

I have a 16 GB Apple Mini iPad using iOS 8.1.2 and am unable to install the bookmark found here that renders LaTeX in the Math Stack Exchange chat room. I can't find a browser with a bookmark bar to drag the given link to.

Other users in the room have also been unable to render LaTeX with their iPad and iPhones. Could you provide instructions that someone who is new to Apple products could follow?

Using Safari:

  1. Copy this in its entirety to your clipboard on your iOS device:

    javascript:(function(){if(window.MathJax===undefined){var%20script%20=%20document.createElement("script");script.type%20=%20"text/javascript";script.src%20=%20"http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML%22;var%20config%20=%20%27MathJax.Hub.Config({%27%20+%20%27extensions:%20[%22tex2jax.js%22],%27%20+%20%27tex2jax:%20{%20inlineMath:%20[[%22$%22,%22$%22],[%22\\\\\\\\\\\\(%22,%22\\\\\\\\\\\\)%22]],%20displayMath:%20[[%22$$%22,%22$$%22],[%22\\\\[%22,%22\\\\]%22]],%20processEscapes:%20true%20},%27%20+%20%27jax:%20[%22input/TeX%22,%22output/HTML-CSS%22]%27%20+%20%27});%27%20+%20%27MathJax.Hub.Startup.onload();%27;if%20(window.opera)%20{script.innerHTML%20=%20config}%20else%20{script.text%20=%20config}%20document.getElementsByTagName(%22head%22)[0].appendChild(script);(doChatJax=function(){window.setTimeout(doChatJax,1000);MathJax.Hub.Queue([%22Typeset%22,MathJax.Hub]);})();}else{MathJax.Hub.Queue([%22Typeset%22,MathJax.Hub]);}})();
