我有一些东西只需要在加载控制器时完成一次.最好的方法是什么?我已经阅读了一些关于"运行块"但我真的不明白它是如何工作的.
一些伪代码:
when /app
resolove some stuff
load a view
controllerA
ControllerA:
Some-magic-piece-of-code-only-run-once{

我想要我的copyCalculation功能.首先,我想检查一下我的数组长度:
var nrOfCalc = browser.element.all(by.repeater('calc in calculations')).count();

我想按下表格中的第一项,然后检查我的数组中是否还有一项.
如何点击表格中的第一项?
我试过这样的事情但是我被卡住了.
var firstRowIn;
browser.findElements(protractor.By.tagName('tr')).then(function(rows){
firstRow = rows[0];

据我了解,这是不可能修复的。React 中的 Typescript 真的很麻烦!
是否可以在 tsx 渲染方法中添加 ts ignore 注释?

无法调用脚本,因为我有 type="module"。如果我没有模块,我将无法访问 Dog 类。如何将 html 事件与模块连接起来?

试图使用async/await.从auth0管理API,你每页只能获得100个用户,所以我要多次请求,直到我拥有所有用户.

我认为重命名的键是在一个对象中定义的(但如果有更好的映射方法就可以了):
