This is MooTools code:
var myString = "{subject} is {property_1} and {property_2}.";
var myObject = {subject: 'Jack Bauer', property_1: 'our lord', property_2: 'savior'};
myString.substitute(myObject);
Does jQuery has this method or similar?
No, but there's nothing preventing you from adding it yourself:
jQuery.substitute = function(str, sub) {
return str.replace(/\{(.+?)\}/g, function($0, $1) {
return $1 in sub ? sub[$1] : $0;
});
};
// usage:
jQuery.substitute('{foo}', {foo:'123'});
