How to access size of 'foreach:' binding in knockout js >

javascript, jquery, knockout.js

Solution

Do you mean within the foreach itself? You can call the parent in the loop, then access the observable array again:

$parent.people().length

Or anywhere you have bound your view model, you can call:

people().length

Or you can add a computed observable to your view model. Inside your view model code, assign this to a var named self, then:

var peopleCount = ko.computed(function()
{
    return self.people().length;
}

Problem

In this doc : http://knockoutjs.com/documentation/foreach-binding.html iteration is achieved using the 'foreach' binding : ``` <tbody data-bind="foreach: people"> ``` Is it possible to access the size of this binding via javascript/jquery ? Something like : `alert('People size is '+people.size);` I need to access the size in order to do a simple validation check.
