量角器：getText() 不起作用 [无法从标题中的 Span 获取文本]

Question

AngularJS： Alert Popup

<div class="modal-header">
<h3>
<span class="firefinder-match" data-ng-show="dialog.stopOrService === 'STOP'" data-translate-values="{"days":"ALL_DAYS","time":"2015-06-20T08:39:46.654Z","stopOrService":"STOP","stopName":"Fairbairn Av after War Memorial Service [3473]","serviceList":[{"serviceNumber":"910","id":"6350571294206984726","name":"910 City via Majura Business Park(Net14NoAir"}],"selectedService":null,"receiveSituations":false,"processing":false}" data-translate="liveDepartures.alerts.addModal.stopHeader">Add a regular alert for upcoming buses at Fairbairn Av after War Memorial Service [3473]</span>
<span class="firefinder-match ng-hide" data-ng-show="dialog.stopOrService === 'SERVICE'" data-translate-values="{"days":"ALL_DAYS","time":"2015-06-20T08:39:46.654Z","stopOrService":"STOP","stopName":"Fairbairn Av after War Memorial Service [3473]","serviceList":[{"serviceNumber":"910","id":"6350571294206984726","name":"910 City via Majura Business Park(Net14NoAir"}],"selectedService":null,"receiveSituations":false,"processing":false}" data-translate="liveDepartures.alerts.addModal.serviceHeader">Add a regular alert for route </span>
</h3>
</div>

断言：使用 getText（）

        var pageHeader = element(by.css('.modal-header > h3 > span'))
        expect(pageHeader.getText()).toContain('Add a regular alert');
        pageHeader.getText().then(function(text){
            console.log("++++++++++++++++++++++++++++++++++++++" +text);
        });

问题：无法从元素获取文本我已经尝试了多种方法来识别模型标题上的"文本"，但无法成功从元素中获取文本。问题似乎未被识别。有人可以帮我解决这个问题吗？

Answer 1

正如错误所确认的那样，您的选择器在 .modal-header 中返回两个跨度。您可以尝试同时捕获它们并指定一个（注意：我没有测试过这些）：

var pageHeader = $$('.modal-header > h3 > span');
expect(pageHeader.get(0).getText()).toContain('Add a regular alert');

或者在选择器上尝试另一种方法。也许尝试:not只返回可见的跨度：

var pageHeader = $('.modal-header span:not(.ng-hide)'); 

Answer 2

正如警告所述，定位器找到多个元素（数组），因此需要get(n)。 你可以等到getText()承诺解决，最后去断言/期望。

var spansInPageHeader = element.all(by.css('.modal-header > h3 > span'));
spansInPageHeader.get(1).getText().then(function(text){
    expect(text).toContain('Add a regular alert');
});
