谷歌Apps脚本：复制页眉/页脚

Question

我试图将文件的元数据复制在我的谷歌开车到另一个。像页面尺寸，查看器，编辑器和页眉/页脚的内容。但标题不会被复制。任何人都知道为什么？

Addtional信息： appendElementToDoc仅搜索追加方法的调用它们，例如appendParagraph。这非常适合复制文档的内容。

/** 
* Copy elements to new doc 
*/ 
function appendElementToDoc(bulk, element) { 

    var tName = underscoreToCamelCase(element.getType() + ""); 
    Logger.log(tName + ""); 
    try { 
    bulk["append" + tName](element); 
    } 
    catch(err) {  
    Logger.log(err + ""); 
    } 
    return bulk; 
} 

/** 
* Transform typename to functio name 
*/ 
function underscoreToCamelCase(type) { 

    type = type.toLowerCase(); 
    var tName = type.charAt(0).toUpperCase() + type.slice(1); 

    var parts = tName.split("_"); 
    if(parts.length == 2) { 
    tName = parts[0] + parts[1].charAt(0).toUpperCase() + parts[1].slice(1); 
    } 

    return tName; 
} 

/** 
* Getting bulk document to insert content 
* 
* @param Document 
* @return Document 
*/ 
function getBulkDocument(template) { 

    var bulk = DocumentApp.create("Bulk Letter"); 
    bulk.setMarginBottom(template.getMarginBottom()); 
    bulk.setMarginLeft(template.getMarginLeft()); 
    bulk.setMarginRight(template.getMarginRight()); 
    bulk.setMarginTop(template.getMarginTop()); 

    bulk.setPageHeight(template.getPageHeight()); 
    bulk.setPageWidth(template.getPageWidth()); 

    var header = bulk.addHeader(); 
    for (var i = 0; i < template.getHeader().getNumChildren(); i++) { 
     appendElementToDoc(header, template.getHeader().getChild(i).copy()); 
    } 

    var footer = bulk.addFooter(); 
    for (var i = 0; i < template.getFooter().getNumChildren(); i++) { 
     appendElementsToDoc(footer, template.getFooter().getChild(i).copy()); 
    } 

    var editors = template.getEditors(); 
    for (var i = 0; i < editors.length; i++) { 
    bulk.addEditor(editors[i]) 
    } 

    var viewers = template.getViewers(); 
    for (var i = 0; i < editors.length; i++) { 
    bulk.addViewer(viewers[i]) 
    } 

    //move to folder 
    DocsList.getFileById(bulk.getId()).addToFolder(DocsList.getFolder("tmp")); 

    return bulk; 
} 

Answer 1

在调用getBulkDocument之后，我确实调用了带有固定documentID的函数，它的工作方式正确。不过还好之前使用：

if(!bulk.getFooter()) { 
    var footer = bulk.addFooter(); 
} else { 
    var footer = bulk.getFooter(); 
} 

完整的例子，复制将跟随我的博客上...
