I am new to jQuery and I am using jQuery 1.7.1 to learn Knockout JS, I was following a video demo by the author. In his example he has a tag something like
<a href="#" class="button-delete">Delete</a>
and in the viewmodel he has something like
$(document).on("click", ".button-delete", function() { console.log("inside"); });
When I tried in my side when I click on the delete button I never see the console.log show up on the console window of the Chrome F12 screen. I have two part question here
- Is there something I am doing wrong which is preventing the console message to show up?
- If I do not have a class to do css, is there any other way to perform the same task in the viewmodel?
edit: I corrected my typo, the code has proper parenthesis (I use web matrix so it take care of those issues). Here is my html
<!DOCTYPE html>
<script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script>
<script src="Scripts/knockout-2.0.0.js" type="text/javascript"></script>
<script src="Scripts/ViewModel.js" type="text/javascript"></script>

<body onload="init()">
<input data-bind="value: tagsToAdd"/>
<button data-bind="click: addTag">Add</button>
<ul data-bind="foreach: tags">
<li>
<span data-bind="text: Name"></span>
<div>
<a href="#" class="btn btn-danger" >Delete</a>
</div>
</li>
</ul>
</body>
</html>
Here is my knockout viewmodel
/// <reference file="jquery-1.7.1.js" />
/// <reference file="knockout-2.0.0.js" />
var data = [
{Id: 1, Name: "Ball Handling" },
{Id: 2, Name: "Shooting" },
{Id: 3, Name: "Rebounding" }
];
function viewModel()
{
var self = this;
self.tags = ko.observableArray(data);
self.tagsToAdd = ko.observable("");
self.addTag = function() {
self.tags.push({ Name: this.tagsToAdd() });
self.tagsToAdd("");
}
}
$(document).on("click", ".btn-danger", function() {
console.log("inside");
});
var viewModelInstance;
function init(){
this.viewModelInstance = new viewModel();
ko.applyBindings(viewModelInstance);
}

जब मैंने कोड को कॉपी करने के बजाय प्रश्न बनाया, मैंने इसे टाइप किया, जबकि मैंने इसे टाइप किया, मैंने टाइपो को प्रश्न में बनाया लेकिन कोड में उचित खुलने और समापन पैराथेसिस था। – Nair
