call an image from URL in Apps Script

问题

I programmed one that calls a Google Doc and in said Doc there is a variable called #Name# this is replaced by the name that is stored in a SpreadSheet.

My question is that to that Doc I want to add a variable called # Photo # and it is replaced by the photo stored in a Drive URL and this URL is in a SpreadSheet

How can I call that URL that is in Spreadsheet and be able to replace the field #photo#

With the name it does well with the function

body.replaceText ('#name#', name);

but with the image I don't know what to call it

回答1:

Since #Photo# is a paragraph of its own, you can do the following:

• Using the Document Body, find the text #Photo# via findText(searchPattern) and get the Element that corresponds to this text via getElement().
• Once you have retrieved this element, you can remove the text (#Photo#), since the element itself will exist even if the text is an empty string. You can use setText("") for that.
• Get the Blob from the image URL via UrlFetchApp.fetch(url) and getBlob().
• Get the retrieved element's parent, which is the paragraph #Photo# was part of, and use insertInlineImage to insert the retrieved image to the beginning of this paragraph.

Code sample:

function replaceTextWithImage() {
  var body = DocumentApp.getActiveDocument().getBody(); // Get current document's body
  var element = body.findText("#Photo#").getElement(); // Get element of #Photo#
  element.asText().setText(""); // Remove #Photo# placeholder
  var url = "YOUR_IMAGE_URL"; // Change this accordingly
  var blob = UrlFetchApp.fetch(url).getBlob(); // Get blob from image URL
  var image = element.getParent().asParagraph().insertInlineImage(0, blob); // Insert image
}

Notes:

• I'm assuming that your question was only about inserting the image to the Document, not about the previous steps of populating the spreadsheet, retrieving the image URL, etc.
• This sample refers to a script that is bound to the Google Doc (hence, it's using getActiveDocument() to retrieve the Doc). If that's not the case, you should retrieve the document via openById(id) or openByUrl(url).
