遍历段落中的单词 [英] Iterating through words in a paragraph

问题描述

所以基本上，我的段落中有一些带下划线的文本，但并非所有文本都有下划线.我希望能够遍历所选文本并更改带有联合国下划线的文本的文本大小.

So basically I have a paragraph with some text underlined, but not all text is underlined. I want to be able to iterate through the selected text and change the text size of the UN-underlined text.

基本上，我希望带下划线的文字更加突出.有没有办法遍历该段落并检查每个单词是否带下划线? GAS中的text元素具有isUnderlined()函数，但这对我没有任何帮助，因为我只知道如何获取整个元素.

Essentially I want the underlined text to stick out more. Is there a way to iterate through the paragraph and check if each word is underlined? The text element in GAS has a isUnderlined() function but that doesn't do me any good since I only know how to grab the entire element.

推荐答案

以下是一些代码，用于评估段落中的每个单词.它将第三段中未加下划线的所有单词加粗.例如，代码获取第3段.您将需要根据您的标准调整代码.该代码假定如果单词的第一个字母带有下划线，则整个单词都带有下划线.每个单词都设置为带有起始索引和结束索引的粗体.

Here is some code that evaluates each word in a paragraph. It bolds every word in the third paragraph that is not underlined. As an example, the code is getting the 3rd paragraph. You will need to adjust the code to your criteria. The code assumes that if the first letter of the word is underlined, that the entire word is underlined. Each word is set to bold with a beginning and ending index.

function findAndBold() {
  var allParagraphs,bodyElement,endPosition,lengthOfThisWord ,numberOfWordsInPara ,
      paragraphAsString,remainingTxtInParagraph,startPosition,text ,theParagraph;

  bodyElement = DocumentApp.getActiveDocument().getBody();
  allParagraphs = bodyElement.getParagraphs();

  //Get a paragraph by index number  E.g. 2 Gets the third paragraph
  theParagraph = allParagraphs[2];
  //Logger.log("theParagraph: " + theParagraph);

  // Only modify elements that can be edited as text; skip images and other
  // non-text elements.
  text = theParagraph.editAsText();
  paragraphAsString = text.getText();
  //Logger.log("paragraphAsString: " + paragraphAsString);

  startPosition = 0;
  endPosition = 0;
  remainingTxtInParagraph = paragraphAsString;
  lengthOfThisWord = 0;
  numberOfWordsInPara = 0;//Initialize with a value of zero

  while (remainingTxtInParagraph.length > 0) {
    Logger.log("remainingTxtInParagraph: " + remainingTxtInParagraph.length);
    numberOfWordsInPara ++;

    lengthOfThisWord = remainingTxtInParagraph.indexOf(" ");
    Logger.log("lengthOfThisWord: " + lengthOfThisWord);

    if (lengthOfThisWord > -1) {
      endPosition = startPosition + lengthOfThisWord;
      Logger.log("startPosition: " + startPosition);
      Logger.log("endPosition: " + endPosition);
    } else {
      lengthOfThisWord = remainingTxtInParagraph.length;
      Logger.log("lengthOfThisWord: " + lengthOfThisWord);
      endPosition = startPosition + lengthOfThisWord - 1;
      Logger.log("final end position: " + endPosition);
      Logger.log("startPosition: " + startPosition);
    };

    remainingTxtInParagraph = remainingTxtInParagraph.substr(lengthOfThisWord + 1); //length is omitted.  Extracts characters to the end
    Logger.log("remainingTxtInParagraph: " + remainingTxtInParagraph.length);

    if (!text.isUnderline(startPosition)) {
      text.setBold(startPosition, endPosition, true);
    };

    startPosition = startPosition + lengthOfThisWord + 1;
    Logger.log("next iteration startPosition: " + startPosition);
    Logger.log(" ");
  };

  Logger.log("numberOfWordsInPara: " + numberOfWordsInPara);
}

该代码结合使用了JavaScript字符串方法，JavaScript字符串length属性以及Apps脚本文本类方法.

The code uses a combination of JavaScript string methods, the JavaScript string length property, along with the Apps Script Text Class methods.
