Question

我有一个小的Javascript代码，我想在之后运行KaTeX完成页面上所有公式的解析。这一点非常重要，因为脚本使用HTML元素的绝对位置（并且在KaTeX渲染期间会发生变化）。我该怎么办？

在我的HTML头中，有

$(()=>{

    function checkAllDownloads() {
        // Ensure your namespace exists.
        window.mynamespace = window.mynamespace || {};

        // Have each of your scripts setup a variable in your namespace when the download has completed.
        // That way you can set async on all your scripts except jquery.
        // Use the document ready event - this code - to check if all your scripts have downloaded.
        if (window.mynamespace.script1 && window.mynamespace.script2){

          // Proceed with page initialisation now that all scripts have been downloaded.
          // [ Add your page initialisation code here ].
          return;
        } 
        // Not all downloads have completed.
        // Schedule another check to give the async downloads time to complete.
        setTimeout(checkAllDownloads, 500);
    }

    // check if it is safe to initialise the page by checking if all downloads have completed.
    checkAllDownloads();

    })

KaTeX完成后，我想运行

KaTex渲染数学后运行脚本
