Question

I am looking for something like:(我正在寻找类似的东西：)

getElementByXpath(//html[1]/body[1]/div[1]).innerHTML I need to get the innerHTML of elements using JS (to use that in Selenium WebDriver/Java, since WebDriver can't find it itself), but how?(我需要使用JS获取元素的innerHTML（要在Selenium WebDriver / Java中使用它，因为WebDriver本身无法找到它），但是如何？) I could use ID attribute, but not all elements have ID attribute.(我可以使用ID属性，但并非所有元素都具有ID属性。) [FIXED]([固定]) I am using jsoup to get it done in Java.(我正在使用jsoup在Java中完成它。) That works for my needs.(这符合我的需求。)   ask by pMan translate from so

You can use document.evaluate :(您可以使用document.evaluate ：)

Evaluates an XPath expression string and returns a result of the specified type if possible.(计算XPath表达式字符串，并在可能的情况下返回指定类型的结果。) It is w3-standardized and whole documented: https://developer.mozilla.org/en-US/docs/Web/API/Document.evaluate(它是W3标准化的，并且完整记录在案： https : //developer.mozilla.org/zh-CN/docs/Web/API/Document.evaluate) function getElementByXpath(path) { return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue; } console.log( getElementByXpath("//html[1]/body[1]/div[1]") ); <div>foo</div> https://gist.github.com/yckart/6351935(https://gist.github.com/yckart/6351935) There's also a great introduction on mozilla developer network: https://developer.mozilla.org/en-US/docs/Introduction_to_using_XPath_in_JavaScript#document.evaluate(Mozilla开发人员网络上也有出色的介绍： https : //developer.mozilla.org/en-US/docs/Introduction_to_using_XPath_in_JavaScript#document.evaluate) Alternative version, using XPathEvaluator :(使用XPathEvaluator替代版本：) function getElementByXPath(xpath) { return new XPathEvaluator() .createExpression(xpath) .evaluate(document, XPathResult.FIRST_ORDERED_NODE_TYPE) .singleNodeValue } console.log( getElementByXPath("//html[1]/body[1]/div[1]") ); <div>foo/bar</div>
