Add striped styling to a list of items

Question

What would be the best way to stripe a list with KnockoutJS? The class on the div below should be even or odd depending where it is in the list, and update when adding or removi

Answer 1

One easy way to do this is to add a computed observable that adds an index to each element, e.g.

    self.logLines = ko.observable(logLinesInput);

    self.enhancedLogLines = ko.computed(function() {
        var res = [];
        $.each(self.logLines(), function(index, ll) { 
             res.push(new LogLine(index, ll)); 
        });
        return res;
    }, self);

In my case LogLine() creates an object with an index field and the other fields that were in the original object.

Now you can easily add zebra stripes to your output:
