Removing Numbers from a String using Javascript
提问by Abs
How do I remove numbers from a string using Javascript?
如何使用 Javascript 从字符串中删除数字？
I am not very good with regex at all but I think I can use with replace to achieve the above?
我对正则表达式不太好，但我认为我可以使用替换来实现上述目的？
It would actually be great if there was something JQuery offered already to do this?
如果 JQuery 已经提供了一些东西来做到这一点，那实际上会很棒吗？
//Something Like this??
var string = 'All23';
string.replace('REGEX', '');
I appreciate any help on this.
我很感激这方面的任何帮助。

\dmatches any number, so you want to replace them with an empty string:
\d匹配任何数字，因此您想用空字符串替换它们：
string.replace(/\d+/g, '')
I've used the +modifier here so that it will match all adjacent numbers in one go, and hence require less replacing. The gat the end is a flag which means "global" and it means that it will replace ALL matches it finds, not just the first one.
我在+这里使用了修饰符，以便它一次性匹配所有相邻的数字，因此需要较少的替换。将g在年底是一个标志，它意味着“全球”，这意味着它将取代所有匹配发现，不只是第一个。

Just paste this into your address bar to try it out:
只需将其粘贴到您的地址栏中即可试用：
javascript:alert('abc123def456ghi'.replace(/\d+/g,''))
\dindicates a character in the range 0-9, and the +indicates one or more; so \d+matches one or more digits. The gis necessary to indicate globalmatching, as opposed to quitting after the first match (the default behavior).
\d表示0-9范围内的一个字符，+表示一个或多个；所以\d+匹配一位或多位数字。该g指示是必要的全球性的匹配，而不是在第一场比赛（默认行为）后退出。
