问题描述

我带着更多量角器问答回来了.因此，在尝试查找滑出菜单内的元素时，我遇到了一个问题.

I'm back with more Protractor Q&A. So, I am coming across an issue when trying for find an element that is inside a slide out menu.

html片段:

<div class="ng-scope" ui-view="navmenu">
<nav class="menu slide-menu-left ng-scope">
  <md-content class="md-default-theme" style="display: table" ng-click="slideMenuLeft()" tabindex="0">
    <button class="md-button md-default-theme" ng-transclude="" 
            style="width:50%;height:72px;border-right:1px solid #ddd;border-bottom:1px solid #ddd" 
            ng-click="checkmap()" tabindex="0">

以下是我尝试从该菜单中获取按钮的方法:

Here are the ways I have tried to grab the the button out of this menu:

element(by.css('Button[ng-click="logoff()"]'));
element(by.xpath('/html/body/section/div[@class="ng-scope"]/nav[@class="menu slide-menu-left ng-scope"]/md-content/button[@ng-click="logoff()"]'));

量角器不喜欢并继续告诉我:

Protractor does not like and proceeds to tell me this:

Stacktrace:
  ElementNotVisibleError: element not visible
  (Session info: chrome=40.0.2214.115)
  (Driver info: chromedriver=2.14.313457 (3d645c400edf2e2c500566c9aa096063e707c9cf),platform=Windows NT 6.3 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 31 milliseconds
Build info: version: '2.45.0', revision: '5017cb8', time: '2015-02-26 23:59:50'

任何人都可以就我可能做错的事情向我提出建议吗?

Can anyone throw me suggestions as to what I may be doing wrong?

推荐答案

在定位并点击子菜单之前需要打开菜单:

You need to open up the menu before locating and clicking the submenu:

element(by.css('nav.menu > md-content')).click();
element(by.css('nav.menu > md-content > button[ng-click="logoff()"]')).click();

您可能还需要使用 elementToBeClickable 预期条件等待子菜单变为可点击(需要量角器 1.7 或更高版本):

You may also need to use a elementToBeClickable expected condition to wait for the submenu to become clickable (needs protractor 1.7 or above):

var EC = protractor.ExpectedConditions;
var logoff = element(by.css('nav.menu > md-content > button[ng-click="logoff()"]'));

browser.wait(EC.elementToBeClickable(logoff), 10000);
logoff.click();
