问题描述
我正在使用nightwatch.js，我对这个自动化测试很新，我想通过nightwatch.js将值设置为元素的style属性，所以我想问，是否可能？如果有可能那么我们如何实现它。
I am working with nightwatch.js and i am quite new into this automation testing, i want to set the value into the style property of an element by nightwatch.js, so i am asking, is it possible ? if it is possible then how can we implement it.
我可以访问样式属性值并可以通过以下nightwatch api命令检查但我找不到任何方法使用nightwatch.js将样式的值设置为元素
I can access the style property values and can check by following nightwatch api command but i couldn't find any way to set the style's value to an element using nightwatch.js
browser.expect.element('#main').to.have.css('display').which.equals('block');
推荐答案
您可以使用以更改元素的样式属性。使用Selenium执行协议，您可以在要测试的站点上执行任意javascript。
You can use the Nightwatch Selenium execute protocol to change the style property of an element. With the Selenium execute protocol you can execute arbitrary javascript on the site to be tested.
例如你可以像这样使用它：
For example you can use it like this:
browser
.execute("document.getElementById('main').style.display = 'block';")
.expect.element('#main').to.have.css('display').which.equals('block');
