Is there a way to do String.Format() in javascript?

Question

So I have a client who does not allow any server side coding, except in rare occurences classic asp, so everything is HTML and javascript.

So basically I need to build a URL from the form and then redirect. Javascript isn't necessarily my thing, but this would take me 5 minutes in asp.net using String.Format.

Is there a String.Format method in javascript?

Answer 1

Ouch, that sucks.

Stolen from another post:

String.format = function() {
  var s = arguments[0];
  for (var i = 0; i < arguments.length - 1; i++) {       
    var reg = new RegExp("\\{" + i + "\\}", "gm");             
    s = s.replace(reg, arguments[i + 1]);
  }

  return s;
}

Answer 2

no, there's no such thing in javascript, but some people have already written a printf for js

e.g JavaScript equivalent to printf/string.format

Answer 3

I was looking for a similar thing and settled on Prototype's "Template" object.

From the Prototype examples

// the template (our formatting expression)
var myTemplate = new Template(
 'The TV show #{title} was created by #{author}.');

// our data to be formatted by the template
var show = {
  title: 'The Simpsons',
  author: 'Matt Groening',
  network: 'FOX'
};

// let's format our data
myTemplate.evaluate(show);
// -> "The TV show The Simpsons was created by Matt Groening."
