我已经设法在网上找到单个计算项的示例,但是有没有人有一个简单的剔除网格的示例,其中一个字段是根据其他字段的值计算的?
编辑:这是我编写的一些代码,但我很确定到目前为止我的做法是错误的:
<script type="text/javascript" src="@Url.Content("~/Scripts/knockout-2.1.0.js")"></script>
<script type="text/javascript">
function QBRatingsViewModel() {
var self = this;
var baseUri = '@ViewBag.ApiUrl';
self.qbratings = ko.observableArray();
this.Interception = ko.observable();
this.Gain = ko.observable();
this.CalculatedRating = ko.computed(function() {
return this.Interception() * this.Gain();
}, this);
$.getJSON("/api/qbrating", self.qbratings);
}
$(document).ready(function () {
ko.applyBindings(new QBRatingsViewModel());
});
</script>
<div style="padding-left: 10px;">
<div id="divQBRatings" style="padding-left: 3px; width: 750px;">
<table class="grid" cellspacing="0" cellpadding="0" id="QBRatingsGrid">
<tr class="gridheader"><td style="width: 30px;">Id</td><td width="10" /><td style="width: 40px;">Season</td><td width="10" /><td style="width: 70px;">Team </td><td width="10" /><td style="width: 130px;">Completion </td><td width="10" /><td style="width: 190px;">Gain </td><td width="10" /><td style="width: 30px;">Touchdown </td><td width="10" /><td style="width: 30px;">Interception </td><td width="10" /><td style="width: 30px;">Rating</td><td width="10" /><td></td></tr>
<tbody data-bind="foreach: qbratings" class="grid">
<tr>
