javascript string remove white spaces and hyphens
提问by Alon
I would like to remove white spaces and hyphens from a given string.
我想从给定的字符串中删除空格和连字符。
var string = "john-doe alejnadro";
var new_string = string.replace(/-\s/g,"")
Doesn't work, but this next line works for me:
不起作用，但下一行对我有用：
var new_string = string.replace(/-/g,"").replace(/ /g, "")
How do I do it in one go ?
如何一次性完成？
回答by Michael Homer
Use alternation:
使用交替：
var new_string = string.replace(/-|\s/g,"");
a|bwill match eitheraor b, so this matches both hyphens and whitespace.
a|b将匹配任何a或b，所以这两个连字符和空格相匹配。
Example:
例子：
> "hyphen-containing string".replace(/-|\s/g,"")
'hyphencontainingstring'

You have to use:
你必须使用：
var new_string = string.replace(/[-\s]/g,"")
/-\s/means hyphen followed by white space.
/-\s/表示连字符后跟空格。

Use This for Hyphens
将其用于连字符
var str="185-51-671";
var newStr = str.replace(/-/g, "");
White Space
空白
var Actuly = newStr.trim();
