Google App腳本文檔應用程序獲取選定的行或詞嗎？

Question

我想選擇單詞或行通過鼠標從Google文檔和腳本我得到這個選定的單詞或行。

var doc=DocumentApp.getActiveDocument(); 
    var docText = doc.editAsText(); 
    var text=docText.getSelection(); 

我試過，但我沒有找到任何選擇的方法，如在VBA

Answer 1

昨天增加了使用光標位置和選定文本的能力，地址爲Issue 2865: Get current user location & state information in Document。請參閱blog post。

事實證明，有一些技巧來處理選擇。我試圖在這裏展示他們 - 請添加評論，如果你找到其他人，我會很樂意更新。

function onOpen() { 
    DocumentApp.getUi().createMenu('Selection') 
    .addItem("Report Selection", 'reportSelection') 
    .addToUi(); 
} 

function reportSelection() { 
    var doc = DocumentApp.getActiveDocument(); 
    var selection = doc.getSelection(); 
    var ui = DocumentApp.getUi(); 

    var report = "Your Selection: "; 

    if (!selection) { 
    report += " No current selection "; 
    } 
    else { 
    var elements = selection.getSelectedElements(); 
    // Report # elements. For simplicity, assume elements are paragraphs 
    report += " Paragraphs selected: " + elements.length + ". "; 
    if (elements.length > 1) { 
    } 
    else { 
     var element = elements[0].getElement(); 
     var startOffset = elements[0].getStartOffset();  // -1 if whole element 
     var endOffset = elements[0].getEndOffsetInclusive(); // -1 if whole element 
     var selectedText = element.asText().getText();  // All text from element 
     // Is only part of the element selected? 
     if (elements[0].isPartial()) 
     selectedText = selectedText.substring(startOffset,endOffset+1); 

     // Google Doc UI "word selection" (double click) 
     // selects trailing spaces - trim them 
     selectedText = selectedText.trim(); 
     endOffset = startOffset + selectedText.length - 1; 

     // Now ready to hand off to format, setLinkUrl, etc. 

     report += " Selected text is: '" + selectedText + "', "; 
     report += " and is " + (elements[0].isPartial() ? "part" : "all") + " of the paragraph." 
    } 
    } 
    ui.alert(report); 
}

你接近。我想你想要findText() method。

var text = docText.findText("some string of text in the document") // for example 

我對VBA並不熟悉，但是這會在文檔中選擇文本。

如果你想找回你選中的文本，可以試試...

function findHighlighted() { 
    var body = DocumentApp.getActiveDocument().getBody(), 
     bodyTextElement = body.editAsText(), 
     bodyString = bodyTextElement.getText(), 
     char, len; 

    for (char = 0, len = bodyString.length; char < len; char++) { 
    if (bodyTextElement.getBackgroundColor(char) == '#ffff00') // Yellow 
     Logger.log(bodyString.charAt(char))} 
} 

從Jonathan's I/O example派生。 但是，請注意，working with cursor position and selections在撰寫本文時尚未提供。

UPDATE： 光標選擇已經上市，見docs。

要添加到Bryan的答案，我寫了這個轉換單個字符以返回已突出顯示的單詞或短語數組。

function findHighlighted() { 
    var results = []; 
    var body = DocumentApp.getActiveDocument().getBody(), 
      bodyTextElement = body.editAsText(), 
      bodyString = bodyTextElement.getText(), 
      char, len; 
    for (char = 0, len = bodyString.length; char < len; char++) { 
      if (bodyTextElement.getBackgroundColor(char) !== null) 
        results.push([char, bodyString.charAt(char)]); 
    } 
    return results; 
} 

function getWords() { 
    var arr = findHighlighted(); 
    var wordList = []; 
    var holding = []; 
    var nextNum, sum; 
    for (var i = 0; i < arr.length; i++) { 
      if (arr[i + 1] === undefined) { 
        nextNum = 0; 
      } else { 
        nextNum = arr[i + 1][0]; 
      } 
      sum = (Number(arr[i][0]) + 1); 
      if (nextNum === sum) { 
        holding.push(arr[i][1]); 
      } else { 
        holding.push(arr[i][1]); 
        wordList.push(holding.join("")); 
        holding = []; 
      } 
    } 
    Logger.log(wordList); 
}
