從文件的身體得到文本字符串，並保留換行符

Question

我有一個谷歌文檔具有文檔中的以下內容：

Hello 
Replace me 
Line 2 

我試圖取代「代替我」，包括換行符，以「我所取代\ n使用2線」，使最終文件的內容等於：

Hello 
I am replaced 
with 2 linesLine 2 

我的我的代碼。只不過：

function myFunction() { 
    var searchString = 'Replace me\n'; 
    var newString = 'I am replaced\nwith 2 lines'; 
    var stringData = DocumentApp.getActiveDocument().getBody(); 
    stringData.replaceText(searchString, newString); 
} 

我試圖改變搜索字符串使用\\n，\v，<br>，<br/>，也許一些其他物品。

我需要什麼searchString來包含還包括換行符？

這裏是sample file with script

Answer 1

function myFunction() { 
    var searchStringNoLineBreak = 'Replace me'; 
    var searchStringRegex = "Replace me\\v"; 
    var substring = "I am replaced\nwith 2 lines"; 

    var body = DocumentApp.getActiveDocument().getBody(); 

    // get all paragraphs 
    var paragraphs = body.getParagraphs(); 

    // loop paragraphs 
    for (var i = 0; i < paragraphs.length; i++) 
    { 
    // current paragraph 
    var p = paragraphs[i]; 

    // if found text with soft return, replace it 
    if (p.findText(searchStringRegex)) 
    { 
     p.replaceText(searchStringRegex, substring); 
    } 

    var isAtTheEnd = p.findText(searchStringNoLineBreak); 

    // if text without newline was found but at the end of paragraph, we need to replace it too 
    if (isAtTheEnd) 
    { 
     // replace text without new line character 
     p.replaceText(searchStringNoLineBreak, substring); 

     // then merge next paragraph with current to remove that new line between them 
     if (i+1 < paragraphs.length) 
     { 
     var nextP = paragraphs[i+1]; 
     nextP.merge(); 
     } 
    } 
    } 
} 

輸入：

結果：
