让PageDown和MathJax一起工作 [英] let PageDown and MathJax work together
问题描述
我正在实现一个UI，该UI看起来很像 math.stackexchange.com 上的UI:
I am implementing a UI which is supposed to look pretty much like the one on math.stackexchange.com:
- 像以前一样使用花式Markdown来进行 stackoverflow
- 在
$...$-符号之间使用MathJax解析公式.
- Using fancy Markdown like you are used to on stackoverflow
- Parsing formulars using MathJax between
$...$-signs.
因此，我下载了PageDown演示并进行了设置，效果很好.现在，我尝试让每次<textarea>更改时都动态加载MathJax.
So I downloaded the PageDown demo and set it up, which works pretty well. Now I try to let MathJax being loaded dynamically everytime the <textarea>changes.
MathJax为此方法提供了示例，但我不是能够使其运行.这是我的"代码的样子:
MathJax got an example for this approach but I'm not able to get it running. This is what 'my' code looks like:
<link rel="stylesheet" type="text/css" href="demo.css" />
<script type="text/javascript" src="../../Markdown.Converter.js"></script>
<script type="text/javascript" src="../../Markdown.Sanitizer.js"></script>
<script type="text/javascript" src="../../Markdown.Editor.js"></script>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.js"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {
inlineMath: [["$","$"],["\\(","\\)"]]
}
});
$("#wmd-input").keypress(function(event){
UpdateMath($(this).val());
});
</script>
<script type="text/javascript" src="../../../mathjax-MathJax-07669ac/MathJax.js?config=TeX-AMS_HTML-full">
</script>
</head>
<body>
<script>
(function () {
var QUEUE = MathJax.Hub.queue; // shorthand for the queue
var math = null; // the element jax for the math output.
QUEUE.Push(function () {
math = MathJax.Hub.getAllJax("#wmd-preview")[0];
});
window.UpdateMath = function (TeX) {
QUEUE.Push(["Text",math,"\\displaystyle{"+TeX+"}"]);
}
})();
</script>
<div class="wmd-panel">
<div id="wmd-button-bar"></div>
<textarea class="wmd-input" id="wmd-input" value=""/>
</textarea>
</div>
<div id="wmd-preview" class="wmd-panel wmd-preview"></div>
<br /> <br />
<script type="text/javascript">(function () {
var converter1 = Markdown.getSanitizingConverter();
var editor1 = new Markdown.Editor(converter1);
editor1.run();
})();
</script>
</body>
每次触发keypress事件时，此代码段都应更新预览.取而代之的是，在页面上加载时，tex可以很好地呈现，但是一旦我开始输入$ ... $代码，就会在预览框中打印出
This snippet should update the preview everytime the keypress event is fired. Instead on page onload the tex is rendered fine but as soon as I start typing the $...$code is printed in the preview box.
推荐答案
I've created a basic example for how to get Pagedown and MathJax working together using a slight modification of Stack Exchange's mathjax-editing.js.
Stack Exchange的代码基于Davide Cervone的代码，请参阅他的评论另一个答案.
Stack Exchange's code is based on Davide Cervone's, see his comment on another answer.
可以在 github 上查看示例代码.
The code for the example can be viewed on github.
