亲爱的
我正在努力解决以下问题。 我尝试在方法内部初始化数组（在全局范围内声明的userByWorkspaces []）。我在方法内部使用了胖箭头运算符。离开粗箭头的范围后，我立即松开数组的内容。
我知道这与上下文“在两者之间的某个地方”的传播有关，但是我找不到解决方法。
请在下面找到代码片段。
在此先感谢您的帮助。
refreshItems() {
console.log('home.component::refreshItems()--> Refreshing Todo list items');
// iterate through all the user workspaces
this.items = [];
JSON.parse(localStorage.getItem('didowi-user')).workspace.forEach((workspace) => {
console.log('home.componenet::refreshItems()--> ... from workspace: ' + workspace);
this.databaseService.fetchItems(workspace).then (result => {
for (let i = 0; i < result.rows.length; i++) {
// take documents whose type === 'item' @see workspace database structure
// if replaced by a mango query in database.service, filtering could be avoided here
if (result.rows[i].doc.type === 'item') {
this.items.push(result.rows[i].doc);
console.log('-------+++++--------- items: ' + this.items);
// this.urls[i] = URL.createObjectURL(result.rows[i].doc._attachments.file.data);
} else if (result.rows[i].doc.type === 'user') {
// take the opportunity to catch users registered in the workspaces (since it comes from the same database
this.usersByWorkspaces.push({'workspace': workspace, 'list': result.rows[i].doc.list});
console.log('-------+++++--------- userbyWorkspaces: ' + JSON.stringify(this.usersByWorkspaces));
}
}
// this.itemCounter = this.items.length;
}, error => {
console.log('home.component::refreshItems()--> Error while fetching data at startup ' + error);
});
console.log('-------OUTSIDE INNER FAT ARROW --------- userbyWorkspaces: ' + JSON.stringify(this.usersByWorkspaces));
});
this.itemCounter = this.items.length;
console.log('-------OUTSIDE--------- userbyWorkspaces: ' + JSON.stringify(this.usersByWorkspaces));
console.log('-------OUTSIDE--------- items: ' + this.items);
}
