How to make a similar filter with ember.js

Question

I have a simple ArrayController in ember pre 1.0 and found that I can slice the list down if the filter finds an exact match for this property, but what I cannot find is how to make a “similar” request with the filter.

What i have below if i am looking for an array with users ...

filtered = ['id', 'username'].map(function(property) { return self.get('content').filterProperty(property, filter); }); 

... and multiple users have the same username. For example => if I search / filter "blacksmith", it will return both records, since the "username" property has an exact match for "smith"

How can I change this map function to work with a similar style request, so when I type the word "cm", it still finds both of these entries

Here is jsfiddle showing the filter shown above in action http://jsfiddle.net/Rf3h8/

Thank you in advance

You can use the RegExp object to check for pieces of data for consistency. As you write your own filter logic, you will have to use the filter function. I updated your script to make this work: http://jsfiddle.net/Rf3h8/1/

Your violin contains a lot of code and can be difficult for others. Here is a very simple example of using RegExp to filter an array.

 var names = ['ryan', 'toran', 'steve', 'test']; var regex = new RegExp('ry'); var filtered = names.filter(function(person) { return regex.test(person); }); filtered // => ['ryan'] 

In fact, you can even reorganize it as

 var filtered = names.filter(regex.test, regex);
