replacing strings

[Rydel]

I have a large VBScript script which extensively uses REPLACE function (to replace substring inside a string with some other substring). I am translating it into JavaScript, so that it could execute in Netscape as well (including older version like NN4 and maybe even NN3). What would you recommend? Is there sucha thing in JS?
Thanks in advance!

Rydel,

You can use the

String.replace

method. An example:

foo = "foo";           // a string literal
regexp = /foo/;        // a regexp literal
replacement = "bar";   // a string literal
alert( "Before: " + foo );
foo = foo.replace( regexp, replacement );
alert( "After: " + foo );

Hope this helps, cheers NEIL s-)

You could even write ur own replace function as follows

function replace(string,text,by) {
var strLength = string.length, txtLength = text.length;
if ((strLength == 0) || (txtLength == 0)) return string;

var i = string.indexOf(text);
if ((!i) && (text != string.substring(0,txtLength))) return string;
if (i == -1) return string;

var newstr = string.substring(0,i) + by;

if (i+txtLength < strLength)
newstr += replace(string.substring(i+txtLength,strLength),text,by);
return newstr;
}

Hope this helps
