以下是我的代码:
var me = this;
gapi.auth.authorize({ client_id: client, scope: scope, immediate: true }, function (authResult: any) {
if (authResult && !authResult.error) {
me.accessToken = authResult.access_token;
} else {
//TODO : show error in front end
}
});
当我像这样使用回调函数时。
gapi.auth.authorize({ client_id: client, scope: scope, immediate: true }, AuthResult);
function AuthResult(authResult: any) {
if (authResult && !authResult.error) {
me.accessToken = authResult.access_token;
} else {
//TODO : show error in front end
}
我没有在回调函数中得到me属性
如何将回调函数包装到其他回调函数中,以便在js中也获得作用域
最佳答案
使用粗箭头:
gapi.auth.authorize({ client_id: client, scope: scope, immediate: true },AuthResult);
const AuthResult = (authResult: any) => {
if (authResult && !authResult.error) {
this.accessToken = authResult.access_token;
} else {
//TODO : show error in front end
}
