| <p>Math textbox with initial LaTeX: <span id="editable-math" class="mathquill-math-field">\frac{d}{dx}\sqrt{x}=</span></p> | |
| <p><small>Try typing <code>1/2\sqrt x</code> and using the arrow keys to move around. Shortcut: use the tab key instead of arrow keys to get "out" of a command, like <code>a_n<span>[tab]</span>x^n</code>. Many LaTeX-style symbols and commands preceded by a backslash are supported, such as <code>\forall</code> or <code>n\choose k</code>.</small></p> | |
| <p>Latex source: <textarea id="latex-source" style="width:80%;vertical-align:top"></textarea></p> | |
| <p><button id="codecogs">Render LaTeX as an image with Code Cogs</button> <a id="codecogslink"><img id="codecogsimg" alt="LaTeX rendered as an image"> <span>Link</span></a></p> | |
| <p><a href="javascript:;" id="show-html-source">Show Semantically Meaningful HTML Source</a></p> | |
| <pre id="html-source"></pre> | |
| <p>You could actually just copy-and-paste this HTML into any element with <code>class="mq-math-mode"</code> on a page that includes the <code>mathquill.css</code> and it would render beautifully, like this: <span class="mq-math-mode" id="html-transplant-example"></span></p> | |
| <p>Any element with <code>class="mathquill-static-math"</code> whose contents are LaTeX source will be rendered as static math: <span class="mathquill-static-math">e^{i\pi}+1=0</span>. Note that if you're only rendering static math, <a href="http://mathjax.org">MathJax</a> supports more of LaTeX and renders better.</p> | |
| <p>In many applications, such as a chat client, you probably type mostly normal text with some math interspersed, so there is also a MathQuill textbox that let's you type math between $'s: <span class="mathquill-text-field">The Quadratic Equation is $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$</span></p> | |
| <p>LaTeX math can also have textboxes inside: <span class="mathquill-static-math">\int\MathQuillMathField{}dx</span> or even <span class="mathquill-static-math">\sqrt{\MathQuillMathField{x^2+y^2}}</span></p> | |
| <p>This button runs the JavaScript code written on it to MathQuill-ify the following <code><span></code> element into an editable math textbox: <button onclick="$(this).text('MQ(this.nextSibling).revert()'); MQ.MathField(this.nextSibling); var orig = arguments.callee; this.onclick = function(){ $(this).text('MQ.MathField(this.nextSibling)'); MQ(this.nextSibling).revert(); this.onclick = orig; };">MQ.MathField(this.nextSibling)</button><span>\frac{d}{dx}\sqrt{x} = \frac{d}{dx}x^{\frac{1}{2}} = \frac{1}{2}x^{-\frac{1}{2}} = \frac{1}{2\sqrt{x}}</span></p> | |
