Bind object in attr binding - KnockoutJs
Have a requirement where in I need to bind object in the value attribute, because KnockoutJs send value as first parameter in checkbox event.
When passed as single value, things are fine.
<div data-bind="foreach: Items">
<input type="checkbox" value data-bind="attr: { value: id }, checked: selectedVal">
this.selectedVal.subscribe((newVal: any) => {
alert(newVal);
});
I want to pass the iterated item object itself, rather than one property of the iterated item.
Items = [
{
id: 1,
name: 'Adam',
},
{
id: 2,
name: 'Bailey',
},
{
id: 3,
name: 'Cathy',
},
]
On subscribe I want entire object with id and name, let me know how I can do that?

You can use checkedValue: $data to tell the checkbox to write the whole object. For example:
const items = [
{
id: 1,
name: 'Adam',
},
{
id: 2,
name: 'Bailey',
},
{
id: 3,
name: 'Cathy',
},
];
const selected = ko.observableArray();
selected.subscribe(console.log);
ko.applyBindings({ items, selected });<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.2/knockout-min.js"></script>
<div data-bind="foreach: items">
<label>
<input type="checkbox" data-bind="checkedValue: $data, checked: selected">
<span data-bind="text: name"></span>
</label>
