以 ASCII 模式显示字符
Displaying characters in pattern from ASCII
就像标题所说的那样,我们想要以 ASCII 值的模式显示一组字符。我们想出了这个代码,但它不起作用...
for (var i = 1; i < 7; i++) {
for (var j = 46; j < i + 1; j++) {
document.write(String.fromCharCode(j));
}
document.write("<br>");
}
for(var k = 8; k > 1; k--) {
for(var l = 97; l < k - 1; l++){
document.write(String.fromCharCode(l));
}
document.write("<br>");
}
输出应该是这样的:
一个
AB
ABC
ABCD
ABCDE
ABCDEF
ABCDEFG
ABCDEFGH
ABCDEFGHI
abcdefgh
abcdefg
abcdef
abcde
abcd
abc
ab
一个
试试这个..
for (var i = 1; i < 10; i++) {
for (var j = 65; j < 65+i; j++) {
document.write(String.fromCharCode(j));
}
document.write("<br>");
}
for(var k = 10; k > 1; k--) {
for(var l = 97; l < 96+k; l++){
document.write(String.fromCharCode(l));
}
document.write("<br>");
}
结果:
A
AB
ABC
ABCD
ABCDE
ABCDEF
ABCDEFG
ABCDEFGH
ABCDEFGHI
abcdefghi
abcdefgh
abcdefg
abcdef
abcde
abcd
abc
ab
a
