• 1 What have you tried? Also, you should take a look at existing JS template engines. – Florian Margaine Commented Apr 25, 2012 at 20:48

Quick & dirty JS template engine:

// Create a matching object for each of your replacement
var matches = {
    "[firstname]": "fred",
    "[lastname]": "smith",
    "[tel]": "123456789"
}

// Loop through the keys of the object
Object.keys( matches ).forEach( function( key ) {
    // Replace every key with its value
    temp = temp.replace( key, matches[ key ] )
} )

Have you tried .replace() ?

You could simply replace them.

temp.replace("[firstname]", "fred").replace("[lastname]", "smith").replace("[tel]", "123456789");

Not sure if you are using jQuery Templates or not.

Try something like this, very basic

function replaceall(tpl, o, _p, p_) {
    var pre = _p || '%',
        post = p_ || '%',
       reg = new RegExp(pre + '([A-z0-9]*)' + post, 'g'),
        str;
    return tpl.replace(reg, function (str, $1) {
        return o[$1];
    });
};
var temp = '<div class="persons">'+
        '<p> <span class="firstname">First Name :</span> <span> [firstname]</span> </p>'+
        '<p> <span class="lastname">Last Name :</span> <span> [lastname]</span> </p>'+
        '<p> <span class="tel">Telephone :</span> <span> [tel]</span> </p>'+
    '</div>',
    data = {
        'firstname':'Fede',
        'lastname':'Ghe',
        'tel' : '+00 012 3456789' 
    };
alert(replaceall(temp, data, '\\\[', '\\\]'));

be cafeful to escape Placeholders bounds and adjust inner regexp if needed hope it helps
