Question

我使用knockout js的示例，但它不起作用。我不知道为什么点击事件没有解雇。

HTML：

<div>
    You've clicked <span data-bind="text: numberOfClicks"></span> times
    <button data-bind="click: incrementClickCounter">Click me</button>
</div>

使用Javascript：

<script type="text/javascript">
    var viewModel = {
    numberOfClicks : ko.observable(0),
    incrementClickCounter : function() {
    alert("hi im click");
    var previousCount = this.numberOfClicks();
    this.numberOfClicks(previousCount + 1);
     }
    };
</script>
