object to json output [Solved]

[arun]

Hi,
I have an object that I would need to write to a json file.

code is mentioned below

Code: Select all

const doc = getDocument();

var layerName = getText()
var entitiesIds = doc.queryLayerEntities(doc.getLayerId(layerName));

const entitiesBBox = []
for (var i = 0; i<entitiesIds.length; ++i) {
    const entityId = entitiesIds[i];
    const bbox = {}
    bbox.id = entityId
    const entity = doc.queryEntity(entityId);
    const box = entity.getBoundingBox()
    bbox.props = {x: box.getMinimum().x, y: box.getMinimum().y, width: box.getWidth(), height: box.getHeight()}
    entitiesBBox.push(bbox)
}

How do I export/write entitiesBBox to a json file

I am using windows/linux and on qcad 3.28.1

Thanks,
Arun

Arun,

First, I don't think you need constants, mostly variables are created with 'var'.

How to create a JSON string from an object:
var exportString = JSON.stringify(object);
https://www.w3schools.com/js/js_json_intro.asp

How to export textual information to a file is something else.
For one, you probably need a file dialog to indicate how the file should be called and where to put it.

Maybe this example can show you how:

Thanks CVH for pointing out on json creation and export.

First, I don't think you need constants, mostly variables are created with 'var'

I guess I have only come across variable declaration using only 'var' in qcad. But, isn't 'const' and 'let' a preferred way of declaring variables than 'var' since ECMA6.

I am still new to js and excuse my questions if they are stupid.

Thanks,
Arun

But, isn't 'const' and 'let' a preferred way of declaring variables than 'var' since ECMA6.

I am convinced that the ECMAScript under QCAD is an early adoption.
On GitHub 'const' returns but 3 hits if we filter on 'JavaScript', all 3 are user contributions.
And none in code for the search term 'let'.

This is another example to export to a text file:
