Question

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class FindElementsUsingJS {

    static WebDriver driver= new FirefoxDriver();


    public static void main(String[] args) {
        driver.get("http://scripting.jdpoweronline.com/mrIWeb/mrIWeb.dll?I.Project=T1_QTYPE&i.test=1");
        // get HTML of above URL
        String scriptContents = "return '<html>'+$( 'html' ).html()+'</html>'";
        String contentss = (String) ((JavascriptExecutor) driver).executeScript(scriptContents);

        // get DOM obj
        String content="return $.parseHTML('"+contentss+"')";
        System.out.println(((JavascriptExecutor) driver).executeScript(content));
        //System.out.println(contentss);
    }
}

嗨，我想做以下事情 1.使用JavascriptExecutor在contentss var中获取HTML文档（正常工作） 2.创建收集的HTML的DOM对象（不工作EXCEPTION）。 3.使用预定义的方法获取DOM的元素。

我遇到了异常

Answer 1

您对scriptContents的字符串文字看起来不对。您在'之前而不是在+之后有+。

这是正确的：

String scriptContents = "'<html>'+$( 'html' ).html()+'<html>'";

希望它有所帮助。
