mathjax-node：格式化在网页上的输出与在节点项目中

时间：2018-07-13 05:00:29

标签： mathjax

我在网页上的mathjax和mathjax-node之间得到了不同的行为。当我将其加载到网页上时，会得到所需的正确输出。例如，我有一个line = $_{a} ^{x} A $，我希望上标和下标彼此上下。如果我在网页上进行转换，则效果很好，但是当我尝试通过mathjax-node运行它时，会得到类似_{ax}A的内容。这是我代码中与mathjax相关的所有内容：

var mathjax = require('mathjax-node');

mathjax.config({   MathJax: {   } });

mathjax.start();

async function formatMath(line) {
try{
  var line;
  if(line.indexOf('$')==-1)
    return line;

  while(line.indexOf('$') > -1){
    var re = /\$(.*?)\$/;
    var match = re.exec(line)[0];
    var math = match.slice(1, -1);


    let result = await mathjax.typeset({
      math: math,
      format: "inline-TeX",
      html: true
    });

    line = line.replace(match, result.html);
    if(line=="$_{a} ^{x} A $"){
      console.log(line);
      console.log(match);
      console.log(math);
    }


  }
  return line;
} catch(err) {
    if(err) {
      return Error(`Error at formMath(): ${err}`);
    }
  }
}

Example of what I am getting using the above function with '$_{a} ^{x} A $'

Example of what I want when I just add html = "\\(_{a} ^{x} A \\)"; directly into the webpage

这是我上面的确切输出：

<span class="mjx-chtml"><span class="mjx-math" aria-label="_{a} ^{x} A "><span c
lass="mjx-mrow" aria-hidden="true"><span class="mjx-msubsup"><span class="mjx-ba
se"><span class="mjx-mi"><span class="mjx-char"></span></span></span><span class
="mjx-stack" style="vertical-align: -0.156em;"><span class="mjx-sup" style="font
-size: 70.7%; padding-bottom: 0.255em; padding-left: 0px; padding-right: 0.071em
;"><span class="mjx-texatom" style=""><span class="mjx-mrow"><span class="mjx-mi
"><span class="mjx-char MJXc-TeX-math-I" style="padding-top: 0.225em; padding-bo
ttom: 0.298em;">x</span></span></span></span></span><span class="mjx-sub" style=
"font-size: 70.7%; padding-right: 0.071em;"><span class="mjx-texatom" style=""><
span class="mjx-mrow"><span class="mjx-mi"><span class="mjx-char MJXc-TeX-math-I
" style="padding-top: 0.225em; padding-bottom: 0.298em;">a</span></span></span><
/span></span></span></span><span class="mjx-mi"><span class="mjx-char MJXc-TeX-m
ath-I" style="padding-top: 0.519em; padding-bottom: 0.298em;">A</span></span></s
pan></span></span>
$_{a} ^{x} A $
_{a} ^{x} A

请注意，我已经尝试过将正则表达式转换为\\((.*)\\)。

我尝试过useGlobalCache和其他选项，但是没有运气。我不明白为什么会这样，或者是否与我的公式设置格式有关。我正在使用“ mathjax-node”：“ 2.1.1” 。预先感谢。

HTML示例实际上是可以的。

我猜您不是在生成和应用CSS。这是一项一次性的工作，因此是服务器端处理的单独步骤。

您需要使用typeset选项运行css，以使mathjax-node将CSS声明添加到结果对象cf中。 https://github.com/mathjax/MathJax-node#typesetoptions-callback。

这是您的OP中应用了CSS的HTML。
