I have a string that has some numbers in the middle of the string.

For example,

var str = "abcd-123456.com"

I want to remove the numbers like this

abcd.com

I am not trying to replace all numbers.
I have to replace only -*. expression with "".
How do I do this in JavaScript?

Your comments lead me to believe you want

var str = "abcd-123456.com";
var str1 = str.substring(0,str.indexOf("-"))+str.substring(str.indexOf("."))
console.log(str1);

//or with regex
  
// dasah plus 6 digits to nothing
var str2 = str.replace(/-\d{6}/,"")
console.log(str2);

// dash, digits and an dot to dot
var str3 = str.replace(/-\d+\./,".")
console.log(str3);

AS PER YOUR COMMENT

The answer of Shivaji Varma will nearly do the tricks.

var str = "abc5d-123456.c0om"  
str = str.replace(/-[0-9]*./g, "")
console.log(str)

Soooo,

Using the slash indicate a regular expression.
[0-9] indicate you want to replace all digit between 0 and 9 (included)
"*" to remove all digits
"-" and "." to delimite

Raising the post at same time, and just to show other solution he may use. I flagged the post, but I think people need to know why they are doing something useless.

str = str.replace(/-[0-9]*./g, "") seems to work. answer updated !
