I want to know the index number of the item selected in the Selection of ux in js.

I want to get the index of Selection from js and create a function.

I can not know the index number currently selected in the SelectionChanged event handler of the Selection.

I used the event handler’s data.current._values[0] in Fuse 0.36.0. But not in Fuse 1.0.0.

Is there any other way to use it?

Hi park,

if you need an explicit index, you have to make sure your data context contains one. So either add it in your original data collection, like so:

var list = [
    {index: 0, title: "some title"},
    {index: 1, title: "some other title"},
    {index: 2, title: "some other title 2"}
];

or if you use Observables, you can make an auto-indexing reactive map for the collection:

var list = Observable();
var indexed = list.map(function(item, index) {
    return {index: index, item: item};
});

Hope this helps!

Would below code help?

 function Select(arg){
	clicked.value=arg.data;
}   

var index = clicked.map(function(x){return Selection.indexOf(x)});
