I am new to knockout.js
. I am following this tutorial. It is working fine on knockout site but not for me. Error console is also not showing any error.
Below is my code
View:
Tasks
<form data-bind="submit: addTask">
Add task: <input data-bind="value: newTaskText" placeholder="What needs to be done?" />
<button type="submit">Add</button>
</form>
<div >
<ul data-bind="foreach: tasks, visible: tasks().length > 0" id="testing">
<li>
<input type="checkbox" data-bind="checked: isDone" />
<input data-bind="value: title, disable: isDone" />
<a href="#" data-bind="click: $parent.removeTask">Delete</a>
</li>
</ul>
</div>
View Model:
<script>
function Task(data) {
this.title = ko.observable(data.title);
this.isDone = ko.observable(data.isDone);
}
function TaskListViewModel() {
// Data
var self = this;
self.tasks = ko.observableArray([]);
self.newTaskText = ko.observable();
self.incompleteTasks = ko.computed(function() {
return ko.utils.arrayFilter(self.tasks(), function(task) { return !task.isDone() });
});
// Operations
self.addTask = function() {
self.tasks.push(new Task({ title: this.newTaskText() }));
self.newTaskText("");
};
self.removeTask = function(task) { self.tasks.remove(task) };
}
ko.applyBindings(new TaskListViewModel(),document.getElementById("testing"));
</script>
