Question

using jquery I need to recognize sequences of characters in a string and replace them with different strings.

starting from this:

    var data = {
       name    : 'Brian',
       surname : 'Logan',
       city    : 'London'
    }

var msg = ' hello <name> <surname> from <city>! '

I need to process the string ‘msg’ to get this:

“Hello Brian Logan from London!”

I used a similar method when I worked in visual foxpro called ‘textmerge’, but I can not find a jquery function which does the same things.

Answer 1

Just pass a replacement function to replace:

String.prototype.format = function(mapping) {
    return this.replace(/<(.*?)>/g, function(match, name) {
        return mapping[name];
    });
};

You can call it like msg.format(data).
