属性获取会调用的是 find_own_property 函数,设置属性会在调用属性基础上多调用 set_value 函数对属性值进行设置,定义会多调用 add_property 函数,add_property 函数会先检查是否先前已经定义过,如果没有就会调用 add_shape_property 函数新建属性。删除属性会调用 delete_property 函数。 私有符号 private symbol 对应...

hasOwnProperty(propertyName):用于检查给定的属性在当前对象实例中(而不是在实例的原型中)是否存在。比如:hasOwnProperty("name")。 isPrototypeOf(object):用于检查传入的对象是否是另一个对象的原型。 PropertyIsEnumerable(propertyName):用于检查给定的属性是否能够使用for-in语句来枚举。
Datalize will then create an object (available as.formin the wider context object) with just the fields you have specified, so you don’t have to list them again. The.form.isValidproperty tells you whether validation was successful or not. ...
