I have the following table row as a script template in KnockoutJs:
<script id="inboxTemplate" type="text/html"> <tr data-bind="click: function() { viewInboxModel.selectAction($data); }"> <td>...</td> <td>${ CreateDate }</td> <td data-bind="click: function(e){ e.preventDefault();viewInboxModel.clearAction($data); }"><img src="/Content/images/delete.png" height="16px" width="16px"> </td> </tr> </script>
The problem is when I click the delete button, it is also running the selectAction() method. I've tried using e.preventDefault() in both selectAction click handler and the clearAction() clicker handler to no avail. Is there anyway KnockoutJs can prevent the underlying row from now being clicked if the delete button is clicked?
Note: The preventDefault() method does not prevent further propagation of an event through the DOM. Use the stopPropagation() method to handle this.
KnockoutJS is basically a library written in JavaScript, based on MVVM pattern that helps developers build rich and responsive websites.
The function you want to bind to the element's click event. You can reference any JavaScript function - it doesn't have to be a function on your view model. You can reference a function on any object by writing click: someObject. someFunction .
$parent : This is the view model object in the parent context, the one immeditely outside the current context. $root : This is the main view model object in the root context, i.e., the topmost parent context. It's usually the object that was passed to ko.
If you have jQuery referenced, then you can safely call e.stopImmediatePropagation();
in your handler, as it is passed the jQuery event object. If you are not using jQuery, then you could still do something like:
e.cancelBubble = true; if (e.stopPropagation) e.stopPropagation();

As per @Benoit Drapeau's comment:
In more recent versions of Knockout you use clickBubble: false. e.g.
<td data-bind="click: myFunction, clickBubble: false"> </td>
