I am building a template tool with Fabric.JS
. I have been able to successful serialize a canvas into DatalessJSON
, and then deserialize the DatalessJSON
back onto the canvas. However, I am having an issue trying to work with the objects once the JSON
has been loaded.
function loadTemplate() {
var template = $('#JSONserial').val();
canvas.clear();
canvas.loadFromDatalessJSON(template);
canvas.renderAll();
var allObjects = canvas.getObjects();
console.log(allObjects);
So here, The canvas is definitely loaded with the JSON
successfully, and all of the objects appear no problem. However, when I try the getObjects
function, the console.log
statement returns "[]"
I have extended the toObjects
function with the 'name'
attribute so that I can identify each of the JSON
loaded objects, but I can't even get that far as I am unable to pull the objects at all.
Any ideas?
loadFromDatalessJson is asyncronous.
loadFromDatalessJSON(json, callback, reviver)
Use the callback to run code at the end of object loading.
function loadTemplate() {
var template = $('#JSONserial').val();
canvas.clear();
var allObjects = [];
canvas.loadFromDatalessJSON(template, function(){
allObjects = canvas.getObjects();
console.log(allObjects);
canvas.renderAll();
});
}
