[FIXED] How to create listener on document.createElement?

Issue

How to create listener on document.createElement func?

For example, after

var canvas = document.createElement("canvas");

it was done automatically

console.log("createElement worked")

P.S. how to do the same but with different functions, for example toDataURL

var str = canvas.toDataURL("image/png");

it was done automatically

console.log("toDataURL worked")

Solution

You can override the original function and add your desired code extension at the beginning.

document.createElement = function (create) {
    return function() {
        console.log ('element created');
        return create.apply (this, arguments);
    };
}(document.createElement)

Example adapted from Hooking document.createElement using function prototype

[FIXED] How to get the Google doc drawings through Document api or appscript

Issue

Hi I have a Google Document that has a Drawing inserted in it, Now I want to get the link of the drawing or get the blob out of the drawing and show

As I use the Document API I was not able to get its properties as is was just empty objects

can someone let me know whether it is feasible or not , If feasible can someone let me know how to fetch the info

Solution

Answer:

It's currently not possible no handle drawings programmatically.

Feature requests:

There's a somewhat related feature request in Issue Tracker:

• Add ability to create and modify drawings

This is reported in the context of Google Apps Script, though, and since the FR is quite old, I'd suggest you to file a new one for Docs API, using this template.
