如何在Javascript中从foreach访问类变量

我想将数据推送到

this.organizationIDList

。我推的时候出错了。如何将数据推送到该变量

 class NewsScreen extends React.Component {
     render() {
         this.organizationIDList = [];

         this.organizations.forEach(function (organization) {
             this.organizationIDList.push(organization.id);
         });
     }
 }

使用

或者将

this

传递给接受

thisArg

            this.organizations.forEach(function (organization) {
                this.organizationIDList.push(organization.id);
            }, this);

上述代码也可以写成：

this.organizationIdList = this.organizations.map(organization =>organization.id);

使用箭头函数，如下所示

this.organizations.forEach((organization) => {
   this.organizationIDList.push(organization.id);
});
