jQuery remove special characters from string and more
提问by Roel
I have a string like this:
我有一个这样的字符串：
var str = "I'm a very^ we!rd* Str!ng.";
What I would like to do is removing all special characters from the above string and replace spaces and in case they are being typed, underscores, with a - character.
我想要做的是从上面的字符串中删除所有特殊字符并替换空格，如果它们被键入，下划线，带有 - 字符。
The above string would look like this after the "transformation":
上面的字符串在“转换”之后看起来像这样：
var str = 'im-a-very-werd-strng';

replace(/[^a-z0-9\s]/gi, '')will filter the string down to just alphanumeric values and replace(/[_\s]/g, '-')will replace underscores and spaces with hyphens:
replace(/[^a-z0-9\s]/gi, '')将字符串过滤为仅字母数字值，replace(/[_\s]/g, '-')并将用连字符替换下划线和空格：
str.replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '-')

Assuming by "special" you mean non-word characters, then that is pretty easy.
假设“特殊”是指非单词字符，那么这很容易。
str = str.replace(/[_\W]+/g, "-")

str.toLowerCase().replace(/[\*\^\'\!]/g, '').split(' ').join('-')

Since I can't comment on Jasper's answer, I'd like to point out a small bug in his solution:
由于我无法评论 Jasper 的回答，我想指出他的解决方案中的一个小错误：
str.replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '-');
The problem is that first code removes all the hyphens and then tries to replace them :) You should reverse the replace calls and also add hyphen to second replace regex. Like this:
问题是第一个代码删除了所有连字符，然后尝试替换它们:) 您应该反转替换调用并将连字符添加到第二个替换正则表达式。像这样：
str.replace(/[_\s]/g, '-').replace(/[^a-z0-9-\s]/gi, '');

Remove/Replace all special chars in Jquery :
删除/替换 Jquery 中的所有特殊字符：
If str = My name is "Ghanshyam" and from "java" background
如果str = 我的名字是“Ghanshyam”并且来自“java”背景
and want to remove all special chars (") then use it
并想删除所有特殊字符 (") 然后使用它
str=str.replace(/"/g,' ')
str=str.replace(/"/g,' ')
result: My name is Ghanshyam and from java background
结果：我的名字是 Ghanshyam，来自 Java 背景
