<h3>MathQuill Editables</h3>
<p>In all editable fields, the selection should clear and ghost parens should solidify if you click outside, but not if you switch tabs/windows and switch back to this page.
<table id="editables">
<tr><th colspan=3>Initial LaTeX
<tr>
<td><span class="mathquill-math-field">\frac{d}{dx}\sqrt{x}=\frac{1}{2\sqrt{x}}</span>
<td><span class="mathquill-text-field">lolwut $a^2 + b^2 = c^2$. Also, awesomesauce: $\int_0^1 \sin x dx.</span>
<td><span class="mathquill-static-math">\sqrt{\MathQuillMathField{x^2+y^2}}</span>
</table>
<p>Touch taps/clicks/mousedown to drag should work anywhere in the blue box: <div class="math-container" style="border: solid 1px lightblue; height: 5em; width: 15em; line-height: 5em; text-align: center; -webkit-tap-highlight-color: rgba(0,0,0,0)"><span class="mathquill-math-field">x_{very\ long\ thing}^2 + a_0 = 0</span></div>
<h3>Redrawing</h3>
<p>
<span id="reflowing-test">\sqrt{}</span>
should look the same as
<span class="mathquill-static-math">
\sqrt{\pi\sqrt\sqrt\frac12}
</span>
</p>
<script type="text/javascript">
$(function() {
var count = 0;
MQ.MathField($('#reflowing-test')[0], {
handlers: { edit: function() { count += 1; } }, // also test 'edit' hook
}).focus().moveToLeftEnd().keystroke('Right');
var textarea = $('#reflowing-test textarea');
// paste some stuff that needs resizing
textarea.trigger('paste');
textarea.val('\\pi\\sqrt{\\sqrt{\\frac12}}');
setTimeout(function() { if (count !== 1) throw 'reflow not called'; });
});
</script>
<h3>Behavior Options</h3>
<p><span id="custom-behavior">x_a^b + \frac{\sqrt[n]{x}}{\frac{1}{2}}</span></p>
<p>Space should behave like Tab, left and right should go through the upper block, sums should start with <code>n=</code>, exponents should require an base, any of <code>+-=&lt;&gt;</code> should break out of an exponent, <code>pi</code>, <code>theta</code>, <code>sqrt</code>, and <code>sum</code> should all be auto-commands, but <code>only</code> should be the only auto-operator name (so <code>sin</code> etc. shouldn't automatically become non-italicized).</p>
<script>
$(function() {
MQ.MathField($('#custom-behavior')[0], {
spaceBehavesLikeTab: true,
leftRightIntoCmdGoes: 'up',
restrictMismatchedBrackets: true,
sumStartsWithNEquals: true,
supSubsRequireOperand: true,
charsThatBreakOutOfSupSub: '+-=<>',
autoSubscriptNumerals: true,
autoCommands: 'pi theta sqrt sum',
autoOperatorNames: 'only'
});
});
</script>
<h3>Up/Down seeking and caching</h3>
<p>
<span id="seek-test" class="mathquill-math-field">
\frac{1}{\sqrt \sqrt \sqrt \sqrt \sqrt \sqrt x}
</span>
</p>
<p>
&uarr; If you hit down from next to the 1, you should end up inside one of the square roots. If you hit up from the right of the x and then hit down again, you should end up where you were.
</p>
<h3>Horizontal overflow</h3>
<p>
<span id="overflow-test">
\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>
(for comparison: <input value="\frac{d}{dx}\sqrt{x}=\frac{d}{dx}x^{\frac{1}{2}}=\frac{1}{2}x^{-\frac{1}{2}}=\frac{1}{2\sqrt{x}}"/>)
</p>
<script>
$(function() {
var overflowTest = $('#overflow-test');
MQ.MathField(overflowTest[0]);
var width = overflowTest.outerWidth(true);
if (width !== 102) {
throw 'math field '+width+'px wide instead of 102px';
}
});
</script>
<h3>Selection Tests</h3>
<p id="selection-tests"><span class="mathquill-text-field different-bgcolor">lolwut $a^2 + b^2 = c^2$. $\sqrt{ \left( \frac{1}{2} \right) }$. Also, awesomesauce: $\int_0^1 \sin x dx.</span>
<p>Even in IE&lt;9, the background color of the parens and square root radical should be the background color of the selection.

<h3>Dynamic rendering performance</h3>

<p id="html-render-perf">HTML: <textarea></textarea> <button>&rarr;</button> <span class="mq-math-mode"></span></p>
<p>There should be no space between here <span class="mathquill-static-math"> </span>and here, even in IE8</p>
<h3>Textcolor</h3>
<p>Colors should match their names:
<span class="mathquill-static-math">
\textcolor{#0000FF}{blue} + \textcolor{red}{red}
= \textcolor { rgb(255, -10, 255) } {magenta}
</span>
</p>
<p>Nested <code>\textcolor</code>: the 2 should be red, the "a+" green, the 4 blue, and the "+b" green again.
<span class="mathquill-static-math">
e^{\textcolor{#FF0000}{2}}\sin(x^\textcolor{#00FF00}{{a+\textcolor{blue}{4}+b}})
</span>
</p>
<h3>Adding CSS class</h3>
<style type="text/css">
.testclass { background-color: #5A8; border-radius: 5px; padding: 4px; font-weight:bold;color:gold;}
</style>
<p>Second term should be styled like <span class='testclass'>this</span>:
<span class="mathquill-static-math">
x+\class{testclass}{y}+z
</span>
</p>
<h3>substituteTextarea</h3>
<p>In Safari on iOS, this should be focusable but not bring up the on-screen keyboard; to test, try focusing anything else and confirm this blurs: <span id="no-kbd-math"></span> (confirmed working on iOS 6.1.3)</p>
