rivets with backbone: calling method (function) on href/onclick attribute
Question
what i'm trying to do is call a funcation like below, further i want to pass current element (item) to function as parameter.
<tr rv-each-item="items:models">
<td><a href="javascript:selectedItem(item);">{ item:Name }</a></td>
</tr>
var selectedItem = function (item)
{
console.log(item);
}
while searching around i found below discussion helpful but could not solve my problem as it does not implement backbone

While working around i found different approaches that can help, posting here if someone can get help or improve if there is any thing needs to.
Option 1
<body>
<div rv-each-book="model.books">
<button rv-on-click="model.selectedBook | args book">
Read the book {book}
</button>
</div>
</body>
<script type="text/javascript">
rivets.formatters["args"] = function (fn) {
var args = Array.prototype.slice.call(arguments, 1);
return function () {
return fn.apply(null, args);
};
};
rvBinder = rivets.bind(document.body, {
model: {
selectedBook: function (book) {
alert("Selected book is " + book);
},
books: ["Asp.Net", "Javascript"]
}
});
</script>
Option 2 Create a custom binder
<body>
<div rv-each-book="books">
<a rv-cust-href="book">
Read the book {book}
</a>
</div>
</body>
<script type="text/javascript">
rivets.binders['cust-href'] = function (el, value) {
//el.href = '/Books/Find/' + value;
//OR
el.onclick = function() { alert(value);};
}
rvBinder = rivets.bind(document.body, {
books: ["Asp.Net", "Javascript"]
});
</script>
Option 3 As I was using rivetsjs with backbone, i can also get advantage of events on backbone view
// backbone view
events: {
'click #linkid': 'linkclicked'
},
linkclicked: function (e){
console.log(this.model.get("Name"));
},
<td><a id="linkid" href="#">{ item:Name }</a></td>
