如何使用 JavaScript 在 InDesign 中為字符下划線？

Question

我開始為 InDesign 編寫這段代碼，為所有字母添加下划線，除了帶有后代的字母，並添加了一個對話框 window 來選擇線條的筆划和偏移量。 現在我有兩個問題：

1. 該程序強調所有字母
2. 行程和偏移量不會改變

我是 Javascript 的初學者，這是第一次為 InDesign 編碼。 有人有線索嗎？ 謝謝！

 // UNDERLINE ALL BUT NO DESCENDANTS



//Make certain that user interaction (display of dialogs, etc.) is turned on.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;

if (app.documents.length != 0){
    try {
      // Run script with single undo if supported
      if (parseFloat(app.version) < 6) {
        main();
      } else {
        app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Expand State Abbreviations");
      }
      // Global error reporting
    } catch ( error ) {
      alert( error + " (Line " + error.line + " in file " + error.fileName + ")");
    }
}else{
    alert("Open a document first before running this script.");
}

在 function underline()中嘗試這些更改：

//REAL FUNCTION
function underline(words,stroke, offset) {  // <------ here 'words' instead of 'charList'
    var charList = words[0].characters;     // <------ here get 'characters' of the 'words'
    var len = charList.length;

    const doNotUnderline = ['g','j','p','q','y'].join(); // <------- here '.join()'
    for (var i=0; i < len; i++){
         try{
            var myChar = charList[i];
            // if (includes(myChar, doNotUnderline) == false) // <----- no need 
            if (doNotUnderline.indexOf(myChar.contents) < 0) // <------ 'indexOf()' instead of 'includes()' 
            {
                myChar.underline = true;
                myChar.underlineWeight = stroke; // <------- here '=' instead of '=='
                myChar.underlineOffset = offset; // <------- here '=' instead of '=='

            } else {
                myChar.underline = false;
            }

         }catch(r){
            alert(r.description);
            break;
        }
    }
}

可能還有其他改進。 它需要額外的研究。 但是，如果您更改這些行，它應該在一定程度上起作用。

還有一件小事可以極大地改善用戶體驗：在輸入字段中保留上次使用的值。 它可以很容易地完成，讓我知道你需要它。
