使用量角器获得背景颜色

我是量角器的新手,我想做的是获取元素的背景颜色.

到目前为止,我有:

var colour = element(by.css("div[class='ng-isolate-scope my-form']")).getCssValue('background-color');
console.log(colour);

我试过'background-color'和'background-color'.

所有我追求的是元素背景颜色,然后我将与我认为它应该是比较.

任何有关这方面的帮助将非常感谢.

您需要解决获得价值的承诺.如果要使用console.log打印它,请执行以下操作:

$('div.my-form').getCssValue('background-color').then(function(bgColor) {
  console.log(bgColor);
});
