我需要 Selenium JavascriptExecutor 通过 jquery 返回一个元素 [英] I need Selenium JavascriptExecutor to return an element via jquery

问题描述

我对此不知所措，我确信答案很简单，但我就是想不通.

I am at my wits end with this and I'm sure the answer is simple but I just can't figure it out.

我有一个 jquery 选择器，当我把它放在谷歌浏览器的控制台中时，它可以完美地找到和元素:

I've got a jquery selector that finds and element perfectly when I put this in the console of google Chrome:

$(".answer__label:contains('Yes')")

现在我想用它来检索 WebDriver 测试中的一个元素，所以我以下列方式使用 JavascriptExecutor:

Now I want to use this to retrieve an element in a WebDriver test, so I'm using JavascriptExecutor in the following way:

private WebElement findByJSText(String text) {
    String script = String.format("return ('.answer__label:contains('%s')')", text);
    WebElement element = (WebElement) ((JavascriptExecutor)driver).executeScript(script);
    return element;
}

这给出了错误，括号中缺少 )".我到处都看到了对这个错误的引用，但似乎没有一个适用于我的情况.

This gives the error, "missing ) in parenthetical". I've seen references to this error all over, but none that seem to apply to my situation.

我如何按摩它以正确返回元素?

How do I massage this to return the element properly?

(请不要回复告诉我使用 driver.findElement(By.linkText)，谢谢)

(please don't respond telling me to use driver.findElement(By.linkText), thanks)

附录

这是我最终的工作方法:

Here's what my final working method looks like:

private WebElement findByJSText(String text) {
    //String script = String.format("return $('.answer__label:contains('%s')')", text);
    String script = String.format("return $(\".answer__label:contains('%s')\")[0]", text);
    WebElement element = (WebElement) ((JavascriptExecutor)driver).executeScript(script);
    return element;
}

我可以为 css 字符串添加第二个参数以使其更灵活.

I may add a 2nd parameter for a css string to make this more flexible.

感谢大家的帮助！

推荐答案

在这一行:

String script = String.format("return ('.answer__label:contains('%s')')", text);

你的javascript代码出错了，jquery的$函数在哪里?正确的js代码应该是:

Your javascript code is error, where is the jquery $ function? Correct js code should be:

String script = String.format("return $('.answer__label:contains('%s')')", text);

您在另一个 ' 中有 '.这就是问题所在，我尝试了以下 js 代码并且对我来说效果很好:

You have the ' within another '. Thats the problem, I tried the following js code and its working fine for me:

String script = String.format("return $(\".answer__label:contains('%s')\")", text);
