问题描述
编写四个单选按钮的代码，希望它们居中对齐.html
Code that writes four radio buttons, would want them centre aligned on .html
public class ScanForWordsC {
private static final Scanner INPUT = new Scanner(System.in);
private static final String FILENAME = "F:/Android.html";
public static void main(String[] args) throws FileNotFoundException {
try (PrintStream output = new PrintStream(FILENAME)) {
readFromUser(output);
}
}
public static void readFromUser(PrintStream output) {
String wordA = readLine("Word (a)");
String wordB = readLine("Word (b)");
String wordC = readLine("Word (c)");
String wordD = readLine("Word (d)");
String answer = readLine("Correct letter");
output.println(radio("a", wordA, answer));
output.println(radio("b", wordB, answer));
output.println(radio("c", wordC, answer));
output.println(radio("d", wordD, answer));
}
private static String readLine(String prompt) {
System.out.print(prompt + ": ");
return INPUT.nextLine();
}
private static String radio(String letter, String word, String answer) {
String option = "(" + letter + ") " + word;
String is = letter.equals(answer) ? "is" : "is not";
return "<input type='radio' name='rbnNumber' value='You selected "
+ option + " which " + is + " the correct answer' />"
+ option + "<br/>";
}
}
我的尝试：
java类，集合和java文档
What I have tried:
java classes, collections and java docs
推荐答案
您可以使用CSS在父级上设置文本对齐方式：
You could use CSS to set the text alignment on the parent:
text-align:center
例如：
For example:
<!DOCTYPE html>
<html>
<body style="text-align:center">
<input type='radio'>First</input><br/>
<input type='radio'>Second</input><br/>
<input type='radio'>Third</input><br/>
</body>
</html>
这里的代码对齐两个单选按钮！但是其他的，有四个按钮对齐方式，css会增加更多的代码如果可以做表格对齐是好的
code here aligns two radio buttons !but others, is there way for four buttons alignment, css would increase more code if could do with table alignment is good
private static String radio(String letter, String word, String answer)
{
String option = "(" + letter + ") " + word;
String is = letter.equals(answer) ? "is" : "is not";
return "<html><table align = 'center'><tr><td>"
+ "<input type='radio' name='rbnNumber' value='You selected"
+ option + "which" + is + "the correct answer'/>"
+ option + "<br/>"
+ "</td></tr></html>";
}
