推荐答案

从1.7.0版开始，levon的代码停止工作.您所需要做的就是修复如下:

As of version 1.7.0 levon's code stopped working. All you need to do is to fix as follows:

// Save additional attributes in Serialization
fabric.Object.prototype.toObject = (function (toObject) {
    return function (properties) {
        return fabric.util.object.extend(toObject.call(this, properties), {
            textID: this.textID
        });
    };
})(fabric.Object.prototype.toObject);

您必须接收properties参数并将其传递给toObject.

You have to receive properties argument and pass it on to toObject.
