*********************************************************************/ 一、参考文档:
. Access class member within callback when inside ES6 class statement
https://*.com/questions/39564038/access-class-member-within-callback-when-inside-es6-class-statement/39564078#39564078 二、解决方法:
. 换别名:
Load() {
const that = this; chrome.storage.sync.get('somesetting',
function (setting) {
console.log(that.Object);
}
);
}
. 采用=>进行处理:
Load() {
chrome.storage.sync.get('somesetting',
setting => {
console.log(this.Object);
}
);
}
