I am trying to convert Knockout contacts example to Polymer just for reference and was wondering if there is an easier method to get the selected index of a row.
Here is the Knockout example I am converting http://jsfiddle.net/rniemeyer/gZC5k/ Here is what I am working on http://jsbin.com/yubigo/2/edit?html,output I know I can find the index by using something like this, this would be for deleting a contact removeContact: function(e, detail, sender){ var obj = e.target.templateInstance.model.row; var found_index = this.data.indexOf(obj); if (found_index !== -1) { this.data.splice(found_index,1); } } Or if I want to pass the index from the template I can do something like using the polymer index syntax and assigning it to a html5 data attribute such as data-idx <template repeat='{{c,idx in data}}'><tr> <td> <input value='{{idx}}' /> <input value='{{c.firstName}}' /> <div><a href='javascript:;' on-tap='{{removeContact}}' data-idx='{{idx}}'>Delete</a></div> </td> <td><input value='{{c.lastName}}' /></td> </tr> </template> But having to add the polymer index syntax and data- attribute or having to search for the index in js each time is a little bit of a pain especially since Polymer already has the index for the selected row. Is the selected index exposed in js somewhere that I am missing?
