填充固定长度的字符串 [英] Padding fixed-length strings
问题描述
任何人都可以告诉我一个正则表达式（或函数或其他）
将字符串填充到固定的字节数？
目前我已经将一个var初始化为N个空格，其中N是
最大字符串我必须填充out，然后我将
的子字符串连接到我的源字符串，以便它以正确的大小结束。这一切都运行良好
但是，如果可能的话，我想要一个更通用/更优雅的制造方法
N个空格。是返回{N} * aString的正则表达式吗？

testString + =" " ;;

到我的源字符串，以便它的大小合适。这一切都很好
但是，如果可能的话，我想要一个更通用/更优雅的方法来制造N个空间。是返回{N} * aString的正则表达式吗？
var lengthRequired = 12
var testString =" test"
while（testString.length< lengthRequired ）{
testString + =" " ;;
}
alert（">" + testString +"<"）
好吧，嗯，引用你的话，你测试过了吗？ ：）

你呢？它看起来有什么问题？

Hi,
Can anyone please show me a regular expression (or function or other) for
padding out a string to a fixed number of bytes?
At the moment I''ve got a var initialized to N spaces, where ''N'' is the
largest string I have to pad out, and then I concatenate a substring of that
to my source string so that it ends up the right size. This all works well
but, if possible, I''d like a more generic/elegant approach to manufacturing
N spaces. Is the a regular expression to returning {N}*aString?
Cheers Richard Maher
