Remove spaces , dots and special chars from a string and replace with hyphen in jQuery
提问by user1831498
I have a string where there may be special characters, which I have to replace with hyphen
我有一个字符串，其中可能有特殊字符，我必须用连字符替换
var str="123.This is,, :ravi"
The above string should be converted like this
上面的字符串应该像这样转换
var newstr="123-This-is-ravi";
I have been trying this
我一直在尝试这个
function remove(str){ str.replace(/\./g, "-"); } //replaces only dots
function remove(str){ str.replace(/ /g, "-"); } //replaces only spaces
Can any one help me doing this? I need to replace special chars with hyphen.
任何人都可以帮助我这样做吗？我需要用连字符替换特殊字符。

You should do the regular expression all at once:
"123.This is,, :ravi".replace(/[\. ,:-]+/g, "-")
Working example:
工作示例：
$('p').html("123.This is,, :ravi".replace(/[\. ,:-]+/g, "-"));<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p></p>That way it will not double up on hyphens.
这样它就不会在连字符上加倍。
One thing to note is that if the value ends with a period (dot), or even any whitespace, then it will end with a hyphen.
需要注意的一件事是，如果值以句点（点）或任何空格结尾，那么它将以连字符结尾。

You could also try to globally replace any non-alphanumeric character and white space by using the function
您还可以尝试使用该函数全局替换任何非字母数字字符和空格
"123.This is,, :ravi".replace(/[\W_]/g, "-")
/[\W_]/g this globally eliminates any non alphanumeric characters and white spaces and can be replaced by anything you chose after the comma,
/[\W_]/g 这会在全局范围内消除任何非字母数字字符和空格，并且可以替换为您在逗号后选择的任何内容，
