Description
A common requirement for a filterBy search in ... is to specify multiple keys to look, but not all of them (as that might produce false positives from fields irrelevant/invisible to the user).
Below is a crude modification of filterBy, dubbed filterByKeys. Usage example:
<li v-repeat="users | filterByKeys searchText in 'firstname' 'lastname'">{{username}}</li>Would it be possible to add this filter to the core (or perhaps replace filterBy with it, as it should be backwards compatible)?
Currently, keeping this in a separate custom filters file requires duplicating the contains function and pulling in the same requirements as for array-filters.js itself.
var filterByKeys = function(){
// Convert arguments to an actual Array
var args = [].slice.call(arguments)
var arr = args.shift()
var search = args.shift()
// cast to lowercase string
search = ('' + search).toLowerCase()
// strip optional 'in'
if (args[0] == 'in'){
delete args[0]
}
// if left with 0 keys, fall back to all keys
var keys = args.length > 0 ? args : Object.keys(args);
// filter input array
return arr.filter(function (item) {
var result = false
keys.forEach(function(datakey){
result = result || contains(Path.get(item, datakey), search)
})
return result;
})
}PS. Possible issues might arise from the arguments conversion as that is a bit funky and I'm not 100% sure of browser compatibility
