Javascript alternative to @ReplaceSubstring

When pushing values in and out of the Query_String I often have to replace spaces with "+" symbols. This is a very simple method for doing this.

string.replace is standard within javascript 1.2
according to Netscape:- (JavaScript 1.3: supports the nesting of a function in place of the second argument)

the string to replace is enclosed within the slashes (/ /) the subsequent g means globally replace (i.e replace all spaces)

, "+" is the character to replace with

Note: as well as the g you can add i which means ignore case.

		Code: function ReplaceSubstring(string){
   //String is of the form "hi to the world"
   var sNewString=string.replace(/ /g, "+")
   //sNewString is of the form "hi+to+the+world"
   return sNewString
}

In the onLoad event add this 
alert(ReplaceSubstring('hi to the world'))
