Accept hash function as an argument #21

axelhzf-tuguu · 2015-12-14T12:53:13Z

I'm having problems with the hash function and complex models

var options = [
{id: 1, comments: [1, 2, 3]},
{id: 2, comments: [4, 5, 6]}
];

var selected = {id : 1, comments: [3, 2, 1]}

The problems here is the order of the comments array. The hash function thinks they are different values.

I think a good solution could be a new parameter to pass the hash function. In my case the hash function should compare only by id

… allow tracking of specific property instead of hole object working examples: * ```option.value as option.label for option in options.data track by option.value``` default: track by 'value' part, same as without track by part * ```option as option.label for option in options.data track by option.id``` hole option item as value, id property for tracking * ```option.value as option.label for option in options.data track by option.value.id``` only value of option as value, id of value for tracking * ```option as option.comments for option in options.data track by option.id``` non working examples: * ```option.value as option.label for option in options.data track by option.id``` tracking property is sibling to value, not the value itself neither a child Closes #21

I implemented it with the 'track by' syntax known from ngRepeat. Please see comment of e7db96e to see some examples

Hi @axelhzf-tuguu ,

If you're using w11k-select and like it, please think about giving an 'I use it' at ngmodules.org
http://ngmodules.org/modules/w11k-select

Thanks & regards,
Philipp
