<span id="jsmath-support"></span><h1>Converting to MathJax from jsMath<a class="headerlink" href="#converting-to-mathjax-from-jsmath" title="Permalink to this headline">ΒΆ</a></h1>
<p>MathJax is the successor to the popular <a class="reference external" href="http://www.math.union.edu/locate/jsMath/">jsMath</a> package for rendering
mathematics in web pages. Like jsMath, MathJax works by locating and
processing the mathematics within the webpage once it has been loaded
in the browser by a user viewing your web pages. If you are using
jsMath with its <tt class="docutils literal"><span class="pre">tex2math</span></tt> preprocessor, then switching to MathJax
should be easy, and is simply a matter of configuring MathJax
appropriately. See the section on <a class="reference internal" href="configuration.html#loading"><em>Loading and Configuring MathJax</em></a> for details.</p>
<p>On the other hand, if you are using jsMath’s <tt class="docutils literal"><span class="pre"><span</span>
<span class="pre">class="math">...</span></span></tt> and <tt class="docutils literal"><span class="pre"><div</span> <span class="pre">class="math">...</div></span></tt> tags to
mark the mathematics in your document, then you should use MathJax’s
<tt class="docutils literal"><span class="pre">jsMath2jax</span></tt> preprocessor when you switch to MathJax. To do this,
include <tt class="docutils literal"><span class="pre">"jsMath2jax.js"</span></tt> in the <cite>extensions</cite> array of your
configuration, with the <cite>jax</cite> array set to include <tt class="docutils literal"><span class="pre">"input/TeX"</span></tt>. For
example,</p>
<div class="highlight-html"><div class="highlight"><pre><span class="nt"><script </span><span class="na">type=</span><span class="s">"text/x-mathjax-config"</span><span class="nt">></span>
<span class="nx">MathJax</span><span class="p">.</span><span class="nx">Hub</span><span class="p">.</span><span class="nx">Config</span><span class="p">({</span>
<span class="nx">extensions</span><span class="o">:</span> <span class="p">[</span><span class="s2">"jsMath2jax.js"</span><span class="p">]</span>
<span class="p">});</span>
<span class="nt"></script></span>
<span class="nt"><script</span>
<span class="nt"> </span><span class="na">src=</span><span class="s">"http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"</span><span class="nt">></span>
<span class="nt"></script></span>
</pre></div>
</div>
<p>would load the <tt class="docutils literal"><span class="pre">jsMath2jax</span></tt> preprocessor, along with a configuration
file that processes TeX input and produces HTML-with-CSS output.</p>
<p>There are a few configuration options for <tt class="docutils literal"><span class="pre">jsMath2jax</span></tt>, which you
can find in the <tt class="docutils literal"><span class="pre">config/default.js</span></tt> file, or in the <a class="reference internal" href="options/jsMath2jax.html#configure-jsmath2jax"><em>jsMath
configuration options</em></a> section.</p>
<p>If you are generating your jsMath documents programmatically, it would be
better to convert from generating the jsMath <tt class="docutils literal"><span class="pre"><span></span></tt> and <tt class="docutils literal"><span class="pre"><div></span></tt> tags
to producing the corresponding MathJax <tt class="docutils literal"><span class="pre"><script></span></tt> tags. You would use
<tt class="docutils literal"><span class="pre"><script</span> <span class="pre">type="math/tex"></span></tt> in place of <tt class="docutils literal"><span class="pre"><span</span> <span class="pre">class="math"></span></tt> and
<tt class="docutils literal"><span class="pre"><script</span> <span class="pre">type="math/tex;</span> <span class="pre">mode=display"></span></tt> in place of <tt class="docutils literal"><span class="pre"><div</span>
<span class="pre">class="math"></span></tt>. See the section on <a class="reference internal" href="model.html#mathjax-script-tags"><em>How mathematics is stored in the
page</em></a> for more details.</p>
