Question

我有以下标记，我正在尝试访问// Get the karma value for nick from the database. func getKarma(nick string, db *sql.DB) string { var karma int rows, err := db.Query("SELECT SUM(delta) FROM karma WHERE nick = $1", nick) if err != nil { log.Fatal(err) } defer rows.Close() karmaStr := fmt.Sprintf("%s has no karma.", nick) if rows.Next() { rows.Scan(&karma) karmaStr = fmt.Sprintf("Karma for %s is %d.", nick, karma) } return karmaStr }

<button />

我有以下内容：

<ul class="flower-list">
  <li ng-repeat="flower in model.flowers">
    <img ng-src="flower.imgUrl">
    <button ng-click="model.addToFlowerPot(flower)">Add</button>
  </li>
</ul>

Answer 1

如果数据来自服务，请检查是否存在延迟。您可以等到

获取数据

browser.waitForAngular()

Answer 2

browser.waitForAngular()不是处理此类案件的理想方式。量角器在内部等待角度事件循环。在这些情况下应该使用Expected Conditions。

 var EC = protractor.ExpectedConditions;
 var flower = element.all(by.repeater('flower in model.flower')).first();
 var addButton = flower.element(by.buttonText("Add"));
 browser.wait(EC.visibilityOf(addButton), 5000); //wait for the button to become visible in dom
 addButton.click();

或直接使用有效的承诺：

  var flower = element.all(by.repeater('flower in model.flower')).first();
  flower.then(function() {
  return flower.element(by.buttonText("Add")).click();
  });

如何让量角器点击我的按钮？我不断得到一个元素是不可见的
