function ViewModel() {
var self = this;
//data
self.stories = ko.observableArray([
{title: "story", inside: "some story", rait: -1},
{title: "story", inside: "Koko jambo", rait: -1},
{title: "story", inside: "trali vali ", rait: -1},
{title: "4 story", inside: "some text": -1},
{title: "5 story", inside: "yo", rait: -1}]),
Rait ++和Rait--必须增加和删除rait。它可以工作但只是在重新加载后。我可以只刷新这篇文章<label data-bind="text: rait"></label>
或我该如何解决这个问题?此外,我尝试使rait属性可观察rait: ko.observable(-1)
,但点击并刷新所有模板后,它返回NaN。
答案 0 :(得分:0)
这只是猜测,但请试试这个:
<button class="plus_btn" data-bind="click:function(){ rait++;rait.valueHasMutated();}">plus</button>
