Extract inner from a span element in selenium/protractor javascript
提问by William Roberts
I have a span element on my page. I was wondering how I could extract the text in between the span opening tag and span closing tag. I'm using selenium with protractor in javascript.
我的页面上有一个 span 元素。我想知道如何提取跨度开始标记和跨度结束标记之间的文本。我在 javascript 中使用 selenium 和量角器。
<span....>
Inner text
</span>

It is actually called a text of an element. Use getText():
它实际上被称为元素的文本。使用getText()：
var elm = element(by.id("myid"));
expect(elm.getText()).toEqual("My Text");
Note that getText()as many other methods in protractor returns a promise. expect()"knows" how to resolve the promise - it would wait until the real text value would be retrieved and only then perform an assertion.
请注意，getText()量角器中的许多其他方法都会返回一个承诺。expect()“知道”如何解决承诺——它会等到真正的文本值被检索到，然后才执行断言。
If you want to see an actual text value on the console, resolve the promise with then():
如果您想在控制台上看到实际的文本值，请使用以下命令解决承诺then()：
elm.getText().then(function (text) {
console.log(text);
});

To find elements on a web page, Protractor uses locators. Read up on them here: https://github.com/angular/protractor/blob/master/docs/locators.mdSince you haven't posted any code, this may differ from the solution you need. The locator I'll use is by using its ID.
为了在网页上查找元素，Protractor 使用定位器。在此处阅读它们：https: //github.com/angular/protractor/blob/master/docs/locators.md由于您尚未发布任何代码，因此这可能与您需要的解决方案不同。我将使用的定位器是使用它的 ID。
var foo = element(by.id('yourspanID')).getText();
