getCssValue (Color) in Hex format in Selenium WebDriver
提问by user2410266
In the following code I need to print the colorin Hex format.
在下面的代码中，我需要打印colorin Hex format。
FirstPrint statement is showing value in RGBformat which is rgb(102,102,102).
首先打印语句显示值RGB的格式是rgb(102,102,102)。
The Secondstatement is showing value in Hexwhich is #666666
在第二个语句显示值在Hex其中#666666
But I am manually entering the value into the second print statement which is 102,102,102.
但是我手动将值输入到第二个打印语句中，即102,102,102.
Is there any way to pass the value which I got from the 1st statement (Color) into the second print statement and get result?
有什么方法可以将我从第一个语句（颜色）获得的值传递到第二个打印语句中并获得结果？
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);
}
}

Way 1: Using StringTokenizer:
方式 1：使用 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);
Way 2:
方式二：
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);

First a quote from Selenium's documentation.
首先引用 Selenium 的文档。
Get the value of a given CSS property. Color values should be returned as rgba strings, so, for example if the "background-color" property is set as "green" in the HTML source, the returned value will be "rgba(0, 255, 0, 1)". Note that shorthand CSS properties (e.g. background, font, border, border-top, margin, margin-top, padding, padding-top, list-style, outline, pause, cue) are not returned, in accordance with the DOM CSS2 specification - you should directly access the longhand properties (e.g. background-color) to access the desired values.
获取给定 CSS 属性的值。颜色值应作为 rgba 字符串返回，因此，例如，如果在 HTML 源代码中将“background-color”属性设置为“green”，则返回值将为“rgba(0, 255, 0, 1)”。请注意，根据 DOM CSS2 规范，不会返回速记 CSS 属性（例如背景、字体、边框、边框顶部、边距、边距顶部、填充、填充顶部、列表样式、轮廓、暂停、提示） - 您应该直接访问普通属性（例如背景颜色）以访问所需的值。
Then this is not a Selenium specific question, this is just a general programming question about how to parse string rgba(102,102,102)to three number.
那么这不是一个 Selenium 特定的问题，这只是一个关于如何将字符串解析rgba(102,102,102)为三个数字的一般编程问题。
// Originally untested code, just the logic.
// Thanks for Ripon Al Wasim's correction.
String color = driver.findElement(By.xpath("//div[@class='gb_e gb_f gb_g gb_xb']/a")).getCssValue("color");
String[] numbers = color.replace("rgba(", "").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);

I know this is rather old, but you can get a simpler solution by using org.openqa.selenium.support.Color:
我知道这已经很老了，但是您可以使用org.openqa.selenium.support.Color以下方法获得更简单的解决方案：
import org.openqa.selenium.support.Color;
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 = Color.fromString(color).asHex();
System.out.println(hex);
It gives you a single line solution and even adds leading zeroes when required (something that the previous answers aren't accounting for)
它为您提供单行解决方案，甚至在需要时添加前导零（以前的答案没有考虑到这一点）

The code works, but just a little typo. The Color.fromString would be upper case C
该代码有效，但只是一个小错误。Color.fromString 将是大写 C
import org.openqa.selenium.support.Color;
String color = driver.findElement(By.xpath("xpath_value")).getCssValue("color");
System.out.println(color);
String hex = Color.fromString(color).asHex();
System.out.println(hex);
