如何将json对象下载为文件 [英] how to download json object as a file

问题描述

我可以使用以下代码将canvas导出到JSON

 var canvas = new fabric.Canvas（'c'）; 
 data = JSON.stringify（canvas）

并且可以使用此电话加载

 canvas.loadFromJSON（data，canvas.renderAll.bind（canvas））; 

我想要的是将数据保存为客户端的文件，为客户端提供将其工作保存在自己机器上的功能，并在需要继续时加载它。



所以如何将JSON对象下载为文件并使用javascript重新加载

i can export canvas to JSON using the following code

var canvas = new fabric.Canvas('c');
data = JSON.stringify(canvas)

and can load back using this call

canvas.loadFromJSON(data, canvas.renderAll.bind(canvas));

what i want is to save the "data" as a file on client side, giving the client the functionality to save his work on his machine and load it whenever he wants to continue

so how to download the JSON object as a file and reload it just using javascript
