Selenium WebDriver中以十六进制格式的getCssValue（Color） [英] getCssValue (Color) in Hex format in Selenium WebDriver

问题描述

在下面的代码中，我需要以 Hex格式打印颜色。

In the following code I need to print the color in Hex format.

第一个 Print语句以 RGB 格式显示值 rgb（102,102,102）。

First Print statement is showing value in RGB format which is rgb(102,102,102).

Second 语句显示 Hex中的值这是＃666666

但我手动输入第二次打印的值语句 102,102,102 。

But I am manually entering the value into the second print statement which is 102,102,102.

有没有办法传递我从第一个语句中获得的值（颜色） ）进入第二个print语句并得到结果？

Is there any way to pass the value which I got from the 1st statement (Color) into the second print statement and get result?

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

public class Google {

    public static void main(String[] args) throws Exception {

        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.google.com/");
        String Color = driver.findElement(By.xpath("//div[@class='gb_e gb_f gb_g gb_xb']/a")).getCssValue("color");
        System.out.println(Color);
        String hex = String.format("#%02x%02x%02x", 102,102,102);
        System.out.println(hex);
    }
}

推荐答案

方式1：使用StringTokenizer：

Way 1: Using StringTokenizer:

String color = driver.findElement(By.xpath("//div[@class='gb_e gb_f gb_g gb_xb']/a")).getCssValue("color");
String s1 = color.substring(4);
color = s1.replace(')', ' ');
StringTokenizer st = new StringTokenizer(color);
int r = Integer.parseInt(st.nextToken(",").trim());
int g = Integer.parseInt(st.nextToken(",").trim());
int b = Integer.parseInt(st.nextToken(",").trim());
Color c = new Color(r, g, b);
String hex = "#"+Integer.toHexString(c.getRGB()).substring(2);
System.out.println(hex);

方式2：

String color = driver.findElement(By.xpath("//div[@class='gb_e gb_f gb_g gb_xb']/a")).getCssValue("color");
String[] numbers = color.replace("rgb(", "").replace(")", "").split(",");
int r = Integer.parseInt(numbers[0].trim());
int g = Integer.parseInt(numbers[1].trim());
int b = Integer.parseInt(numbers[2].trim());
System.out.println("r: " + r + "g: " + g + "b: " + b);
String hex = "#" + Integer.toHexString(r) + Integer.toHexString(g) + Integer.toHexString(b);
System.out.println(hex);
