<title>click Binding</title>
<meta charset="UTF-8"/>
<style>
*{
margin: 0px 0px 0px 0px;

font-size: 2em;
font-weight: bold; /*粗體*/
}
</style>
</head>
<body>
<script src="../lib/knockout-2.1.0.js"></script>
<script>
(function(window , undefined ){
var ko = window.ko,
manager = window.manager || {};
manager.viewModel = {
colors:ko.observableArray(['darkgreen','darkgrey','darkmagenta','darkorange']),
colorIndex:-1,
changeColor:function(data , event){
//被點擊的項目可由event取回
//若需改變其他DOM，則需在init時將需改變的DOM參照記錄於viewModel中
(data.colorIndex >= data.colors().length-1 && (data.colorIndex = -1));
event.srcElement.style.backgroundColor = data.colors()[++data.colorIndex] ;
},
controlName:'Click Me'
};
window.manager = manager;
})(window);
window.onload = function(){
ko.applyBindings( manager.viewModel);
};
</script>
<div class="cube" id="myCube" data-bind="click:changeColor , text:controlName"></div>
