Google Docs Apps Script 获取列数

Question

On a Google Doc you can set columns from Format > Columns. Now, though, I want to access those columns from Apps Script to confirm the number of columns. I don't even need to modify them, just access. I haven't found anything that jumps out at me from the documentation, so I didn't know if there's an extension of the Document service that would allow for such. I'm sorry not to include any code, but I have no code obvious to show. I did create a document with 2 columns to see exactly what I'm talking about. https://docs.google.com/document/d/1MyttroeN4kPUm9PfYZnTe_gJqstM3Gb5q3vS3c84dNw/edit

Answer 1

Answer

It is possible using the get method of the Google Docs API

How to do it

1. In Apps Script, enable the Advanced Docs Service .
2. Use the method get .
3. Check the array called content .
4. Search an object called sectionBreak in each element of content .
5. Check that the object has the following data: sectionBreak>sectionStyle>columnProperties .
6. Take the length of the array columnProperties .
7. (keep in mind that the first occurrence of columnProperties is in the first element of content , skip it and start the loop from the second one.

Code

function myFunction() {
  var id = DocumentApp.getActiveDocument().getId()
  var result = Docs.Documents.get(id)
  var content = result["body"]["content"]
  for (var i = 1; i < 20; i++) {
    try {
      var cols = content[i]["sectionBreak"]["sectionStyle"]["columnProperties"]
      console.log('number of columns: ' + cols.length)
    } catch (error) {
    }

  }
}
