Java API Sorting Bookmarklet

readable.js

/*
  For sorting the method tables by return type in the Java API.

  To use: make a bookmarklet whose URL is exactly the following:
    javascript:(function(){const%20TABLE_CLASS=".memberSummary";const%20ROWS_OTHER_THAN_FIRST_SELECTOR="tr:not(:first-child)";const%20methodTable=document.querySelector(TABLE_CLASS);const%20tbody=methodTable.querySelector("tbody");const%20allRows=tbody.querySelectorAll(ROWS_OTHER_THAN_FIRST_SELECTOR);const%20sortAlphabetically=(firstString,secondString)=>{if(firstString===secondString){return%200;}if(firstString<secondString){return-1;}if(firstString>secondString){return%201;}};const%20sortByInnerText=(firstHtmlElement,secondHtmlElement)=>{const%20firstText=firstHtmlElement.innerText;const%20secondText=secondHtmlElement.innerText;return%20sortAlphabetically(firstText,secondText);};const%20sortRowByFirstColumn=(firstRow,secondRow)=>{return%20sortByInnerText(firstRow.querySelector("td"),secondRow.querySelector("td"));};const%20sortByJdocRowId=(firstJavadocRow,secondJavadocRow)=>{const%20firstId=firstJavadocRow.id;const%20secondId=secondJavadocRow.id;return%20sortAlphabetically(firstId,secondId);};const%20removeTableRows=()=>{allRows.forEach(element=>element.remove());};const%20replaceRowsWith=(collectionToReplaceWith)=>{removeTableRows();collectionToReplaceWith.forEach(element=>tbody.appendChild(element));};const%20rowsSortedByJdocRowId=Array.from(allRows).sort(sortByJdocRowId);const%20rowsSortedByType=Array.from(allRows).sort(sortRowByFirstColumn);if(methodTable.classList.contains("bookmarkletSortedAsc")){replaceRowsWith(rowsSortedByType.reverse());methodTable.classList.add("bookmarkletSortedDesc");methodTable.classList.remove("bookmarkletSortedAsc");}else%20if(methodTable.classList.contains("bookmarkletSortedDesc")){replaceRowsWith(rowsSortedByType);methodTable.classList.remove("bookmarkletSortedDesc");}else{replaceRowsWith(rowsSortedByJdocRowId);methodTable.classList.add("bookmarkletSortedAsc");}})();

  (The above is just `javascript:` plus everything below, but with spaces and linebreaks removed.)
