string dot notation to brackets

I have a string e.g.

 

products.0.name

 

and I want to change the string to;

 

products[0][name]

 

I have come up with some code that works but is a bit of a hack, my code is below;

var array = field.split(".");
field = array[0]+'['+array[1]+']['+array[2]+']';

Is there a better way, I am sure there is using regex?

 

 

Thanks

Your question is not clear are you wanting convert the string 'products.0.name' to the string 'products[0][name]' or are wanting to convert it to array notation so you can return the name item from the array at index 0 of the variable named products?

 

sorry, yes, i would like the string 'products.0.name' converted to string 'products[0][name]'

Your way words just fine. The other way would be to use regex

field = field.replace(/(\w+)\.(\d+)\.(\w+)/g, '$1[$2][$3]');

 

Thanks, I knew there would be a regex way, I am just useless when it comes to regex!
 
I am guessing the .replace is quicker as it is done with one function?
