                        elem.click();
                        browser.sleep(5000);
                       quizPageElements.clickNextQn();
                        // browser.sleep(15000);
                        browser.waitForAngular();

尝试将每个元素放入<ul>标记内，并使用量角器中的evaluate函数获取范围变量的id并检查条件，然后单击选项元素，然后单击下一步按钮。有时会在evaluate函数中出现此错误。

Answer 1

由于无法避免陈旧错误，我只是尝试在evaluate函数中捕获错误，并在发生错误时继续单击元素。赞，

element.all(by.css('#options-ul li')).each(function (elem, index) {
                return elem.evaluate('option').then(function (value) {
                    if (correctAns.indexOf(value.Id)!==-1) {
                        elem.click();
                        browser.sleep(5000);
                       quizPageElements.clickNextQn();
                        // browser.sleep(15000);
                        browser.waitForAngular();
                    }
                },function(err){
             //do operation to click a button
             });
         });

失败：量角器中的陈旧元素引用
