如何格式化我在Google App Script中从Google文档复制的文字？ [英] How do I format text I am copying from Google Document in Google App Script?
问题描述
我试图从一个文档复制格式化文本并将其粘贴到另一个文档中。我想通过Google应用程序脚本获取整个文档并将其添加到另一个文档。
$ b
调用 body.getText（）满足我的用例，但将文本作为字符串获取，未格式化。
能够将格式化文本从一个文档复制到另一个文档是非常棒的。
编辑：
接受建议我目前写了更多的代码。几乎完全遵循另一个答案，我仍然只获取文本而不是格式化。
for（var i = 0; i< numElements; ++ i）{
var element = copyBody。 getChild（i）
var type = element.getType（）;
if（type == DocumentApp.ElementType.PARAGRAPH）
{
var newElement = element.copy（）。asParagraph（）;
newBody.appendParagraph（newElement）;
else if（type == DocumentApp.ElementType.TABLE）
{
var newElement = element.copy（）。asTable（）;
newBody.appendTable（newElement）;
}
else if（type == DocumentApp.ElementType.LIST_ITEM）
{
var newElement = element.copy（）。asListItem（）;
newBody.appendListItem（newElement）;
}
其他{
Logger.log（WRONG ELEMENT）
}
}
这个答案涵盖它。
您需要遍历源文档的元素，将每个元素附加到目标文档。您不要复制文本版本的段落等，而是复制整个元素，包括格式等。
脚本
由于文档现在支持可编程UI元素，因此这里是一个基于Henrique以前答案的脚本（上面），其中包括一个用于驱动文档合并的自定义菜单。您可以选择包含附加文档之间的分页符 - 如果您正在尝试创建多分章文档，则很有用。
此脚本必须包含在文档中（或者没有UI

编辑：通过处理来自Serge's回答，处理图像大小属性。正如注释所表明的那样，在append中存在一些属性被阻塞的问题，因此引入了 clean（）辅助函数并使用了 .setAttributes（）。 然而，你会注意到对 .setAttributes（）的调用被注释掉了;这是因为它也有一个副作用，会删除一些格式。这是你想要处理的烦恼的选择。
I am trying to copy formatted text from one document and paste it into another. I want to take the entirety of one document and add it to another via Google App Script.
The call body.getText() satisfies my use case but gets the text as a string, not formatted.
It would be great to be able to copy formatted text from one document to another.
EDIT: Taking the advice I currently wrote some more code. Following the other answer almost exactly, I am still only getting the text and not the formatting too.
for(var i = 0; i < numElements; ++i) {
var element = copyBody.getChild(i)
var type = element.getType();
if (type == DocumentApp.ElementType.PARAGRAPH)
{
var newElement = element.copy().asParagraph();
newBody.appendParagraph(newElement);
}
else if(type == DocumentApp.ElementType.TABLE)
{
var newElement = element.copy().asTable();
newBody.appendTable(newElement);
}
else if(type == DocumentApp.ElementType.LIST_ITEM)
{
var newElement = element.copy().asListItem();
newBody.appendListItem(newElement);
}
else{
Logger.log("WRONG ELEMENT")
}
}
This answer covers it.
You need to iterate through the elements of the source document, appending each to the destination doc. You don't copy Text versions of paragraphs, etc., instead you copy the whole element including formatting etc.
Script
Since Documents now support programmable UI elements, here's a script based on Henrique's previous answer (above), that includes a Custom Menu to drive the merge of documents. You may optionally include page breaks between appended documents - useful if you are trying to create a multi-chapter document.
This script must be contained in a Document (or no UI for you)!
/**
* The onOpen function runs automatically when the Google Docs document is
* opened.
*/
function onOpen() {
DocumentApp.getUi().createMenu('Custom Menu')
.addItem('Append Document','appendDoc')
.addToUi();
}
/**
* Shows a custom HTML user interface in a dialog above the Google Docs editor.
*/
function appendDoc() {
// HTML for form is rendered inline here.
var html =
'<script>'
+ 'function showOutput(message) {'
+ 'var div = document.getElementById("output");'
+ 'div.innerHTML = message;'
+ '}'
+ '</script>'
+ '<form id="appendDoc">'
+ 'Source Document ID: <input type="text" size=60 name="docID"><br>'
+ 'Insert Page Break: <input type="checkbox" name="pagebreak" value="pagebreak">'
+ '<input type="button" value="Begin" '
+ 'onclick="google.script.run.withSuccessHandler(showOutput).processAppendDocForm(this.parentNode)" />'
+ '</form>'
+ '<br>'
+ '<div id="output"></div>'
DocumentApp.getUi().showDialog(
HtmlService.createHtmlOutput(html)
.setTitle('Append Document')
.setWidth(400 /* pixels */)
.setHeight(150 /* pixels */));
}
/**
* Handler called when appendDoc form submitted.
*/
function processAppendDocForm(formObject) {
Logger.log(JSON.stringify(formObject));
var pagebreak = (formObject.pagebreak == 'pagebreak');
mergeDocs([DocumentApp.getActiveDocument().getId(),formObject.docID],pagebreak);
return "Document appended.";
}
/**
* Updates first document in list by appending all others.
*
* Modified version of Henrique's mergeDocs().
* https://stackoverflow.com/a/10833393/1677912
*
* @param {Array} docIDs Array of documents to merge.
* @param {Boolean} pagebreak Set true if a page break is desired
* between appended documents.
*/
function mergeDocs(docIDs,pagebreak) {
var baseDoc = DocumentApp.openById(docIDs[0]);
var body = baseDoc.getBody();
for( var i = 1; i < docIDs.length; ++i ) {
if (pagebreak) body.appendPageBreak();
var otherBody = DocumentApp.openById(docIDs[i]).getBody();
Logger.log(otherBody.getAttributes());
var totalElements = otherBody.getNumChildren();
var latestElement;
for( var j = 0; j < totalElements; ++j ) {
var element = otherBody.getChild(j).copy();
var attributes = otherBody.getChild(j).getAttributes();
// Log attributes for comparison
Logger.log(attributes);
Logger.log(element.getAttributes());
var type = element.getType();
if (type == DocumentApp.ElementType.PARAGRAPH) {
if (element.asParagraph().getNumChildren() != 0 && element.asParagraph().getChild(0).getType() == DocumentApp.ElementType.INLINE_IMAGE) {
var pictattr = element.asParagraph().getChild(0).asInlineImage().getAttributes();
var blob = element.asParagraph().getChild(0).asInlineImage().getBlob();
// Image attributes, e.g. size, do not survive the copy, and need to be applied separately
latestElement = body.appendImage(blob);
latestElement.setAttributes(clean(pictattr));
}
else latestElement = body.appendParagraph(element);
}
else if( type == DocumentApp.ElementType.TABLE )
latestElement = body.appendTable(element);
else if( type == DocumentApp.ElementType.LIST_ITEM )
latestElement = body.appendListItem(element);
else
throw new Error("Unsupported element type: "+type);
// If you find that element attributes are not coming through, uncomment the following
// line to explicitly copy the element attributes from the original doc.
//latestElement.setAttributes(clean(attributes));
}
}
}
/**
* Remove null attributes in style object, obtained by call to
* .getAttributes().
* https://code.google.com/p/google-apps-script-issues/issues/detail?id=2899
*/
function clean(style) {
for (var attr in style) {
if (style[attr] == null) delete style[attr];
}
return style;
}
Edit: Adopted handling of inline images from Serge's answer, with handling of image size attributes. As the comments indicate, there have been problems with some attributes being snarfed in the append, thus the introduction of the clean() helper function and use of .setAttributes(). However, you'll note that the call to .setAttributes() is commented out; that's because it too has a side-effect that will remove some formatting. It's your choice about which annoyance you'd rather deal with.
