Remove Symbols From String But Keep Numbers?

Jul 7, 2011

I want to remove all symbols of an input string, so I have this javascript command:

Code:
this.value=this.value.replace(/[,.s;/\:{}[]<>?`~!@#$%^&*()_+-=]/g,"");

But, this command removes also the numbers. How can I keep the numbers but remove the symbols?

Compare String With Numbers In Javascript

Jul 23, 2005

if (123 > 33) will return true

and

if ("123" > 33) will return true

So my question is, if the above behaviors are the same?? If string is
a number, and compare with another number, it will be the same behavior as compare 2 numbers?

In this case, it is comparing 2 strings that are numbers, so they are
string comparisons here. correct?

if ("123" > "33") will return true

In this case, "33a" is not a number, that's why when it compare with
another number, it always return false. correct?

if ("33a" > 33) will return false...
