Javascript Regex to convert dot notation to bracket notation
- by Tauren
Consider this javascript:
var joe = {
name: "Joe Smith",
location: {
city: "Los Angeles",
state: "California"
}
}
var string = "{name} is currently in {location.city}, {location.state}";
var out = string.replace(/{([\w\.]+)}/g, function(wholematch,firstmatch) {
return typeof values[firstmatch] !== 'undefined' ?
values[firstmatch] : wholematch;
});
This will output the following:
Joe Smith is currently in {location.city}, {location.state}
But I want to output the following:
Joe Smith is currently in Los Angeles, California
I'm looking for a good way to convert multiple levels of dot notation found between braces in the string into multiple parameters to be used with bracket notation, like this:
values[first][second][third][etc]
Essentially, for this example, I'm trying to figure out what regex string and function I would need to end up with the equivalent of:
out = values[name] + " is currently in " + values["location"]["city"] +
values["location"]["state"];
