填充固定长度的字符串

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？

var lengthRequired = 12

var testString =" test"

while（testString.length< lengthRequired ）{

testString + =" " ;;

}

提醒（">" + testString +"<"）

好​​吧，嗯，引用你的话，你测试过了吗？ ：）

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

var lengthRequired = 12
var testString = "test"
while (testString.length<lengthRequired){
testString += " ";
}
alert(">" + testString + "<")

Well, um, to quote you, "Did you test that?" : )
