How can I replace values in an array of variables with jQuery

Question

I have this code

newRow =  "<tr><td>[[var1]]</td><td>[[var2]]</td><td>[[var3]]</td></tr>"

Now i have this array

data['var1'] ='test1';
data['var2'] ='test2';
data['var3'] ='test3';

I want to replace the above data in newRow in simplest possible way. How can I do that?

its a bit unclear, can you provide more details of what you're trying to do. — Wern Ancheta

$.each(data, function(key, item) {
    newRow = newRow.replace('[[' + key + ']]', item);
});

thank sbuddy , that was good. One thing more , will it work if i have multiple instances of [[var1]] in the same variable. i think it will stop after replacing the first one

No need for jQuery:

newRow = newRow.replace(/\[\[(\w+)\]\]/g, function($0, $1) {
  return ($1 in data ? data[$1] : '');
  // empty string as fallback, if not available in data
});
