Simple javascript template system

If you want to use strings as simple templates in javascript, you might want to use my template script. You can do stuff like this:

var template = “Hello my name is {person.name}, I’m {person.age} years old, I like {person.favorites.fruit}, but at most I like {person.favorites.fruit[2]}”;

var replaceVars = {person:{name:”Mark”, age:27, favorites:{fruit:[“apples”,”oranges”, “bananas”] }}};

alert( stroep.core.StringUtil.replaceVars(template , replaceVars) );

// output: Hello my name is Mark, I’m 27 years old, I like apples, oranges, bananas, but at most I like bananas.

You can also use a function inside the template.

var template = “I’m {person.age} years, I feel {customFunction(person.age)}”;

function customFunction(age) {
return age > 50 ? “old” : “young”;
}

alert(  stroep.core.StringUtil.replaceVars(template, {person:{age:27}})  );

// output: I’m 27 years, I feel young

If nothing is found, the variables inside the templates are not going to be replaced.
Alright, here is the javascript util class. Have fun!
