量角器JavaScript获取文本标签h1

如何解决量角器JavaScript获取文本标签h1

我正在努力从Web元素获取文本。我想将文本返回给函数调用者，但它始终返回null。

function loadWebsite(url)
{
  try{
    var retText = null;
    browser.get(url);
    browser.sleep(5000);
    browser.ignoreSynchronization = true;

    var eleWelcomeTxt = element(by.css(".intro-content"));
    browser.wait(EC.textToBePresentInElement(eleWelcomeTxt),5000);

    eleWelcomeTxt.getText().then(function(text){
      retText = text;
    });
  }catch(err){
    console.log("exception error: " + err.message);
  }

  return retText;
}

然后我正试图在标签h1处获取文本

public class Levels {

    @SerializedName("game")
    public List<Game> game;

    /**
     * No args constructor for use in serialization
     *
     */
    public Levels() {
    }

    /**
     *
     * @param game
     */
    public Levels(List<Game> game) {
        super();
        this.game = game;
    }

    public List<Game> getGame() {
        return game;
    }

    public void setGame(List<Game> game) {
        this.game = game;
    }

    public Levels withGame(List<Game> game) {
        this.game = game;
        return this;
    }

}

该函数始终返回null;

解决方法

问题1.更改CSS选择器 element（by.css（“。intro-content h1”））;

问题2。答应包装您的代码

async function loadWebsite(url)
{
return new Promise(async(resolve,reject)=>{

try{
       await browser.get(url);
       await browser.sleep(5000);
       browser.ignoreSynchronization = true;
       let eleWelcomeTxt = element(by.css(".intro-content h1"));
       await browser.wait(EC.textToBePresentInElement(eleWelcomeTxt),5000);
       let text = await eleWelcomeTxt.getText();
       return resolve(text);
       }catch(err){
        console.log("exception error: " + err.message);
        return reject();
      } 
})
}

,

根据doc，EC.textToBePresentInElement方法接受2个参数

EC.textToBePresentInElement(element,elementText)

实际上并不是很确定要执行的操作，仅举一个如何验证元素中文本的示例：

/*
 * get element Text
 * @param container - the container of the desired element
 * @param elementToGet - the class name of the element to get
 * @param value - value to check
 */
expectElementTextToEqual: function (container,elementName,expectedVal) {
    ptor.ignoreSynchronization = true;
    this.elementloadedInDOM(container);
    let cont = element.all(by.className(container)).first();
    cont.isDisplayed();
    let el = cont.all(by.className(elementName)).first();
    el.isEnabled();
    el.isDisplayed();
    expect(el.getText()).toEqual(expectedVal);
},
