为了让附加的代码正常工作,我几乎整天都在沮丧地玩耍。代码或多或少取自http://jsfiddle.net/rniemeyer/5Xr2X/。我的版本显示第一页,IE,前 10 行。单击下一步会触发 pagedRows 函数,但不会在我的一生中显示下一页数据。嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻嘻
附上代码
<table>
<tr>
<th>Id</th>
<th>Type</th>
<th>Name</th>
</tr>
<tbody data-bind='template: { name: "fieldTemplate", foreach: pagedRows }'></tbody>
</table>
<a href="#" data-bind="click: previous, visible: pageIndex() > 0">Previous</a>
<a href="#" data-bind="click: next, visible: pageIndex() < maxPageIndex()">Next</a>
<script type="text/html" id="fieldTemplate">
<tr>
<td><span data-bind="text:FieldId" /></td>
<td><span data-bind="text:Type" /></td>
<td><span data-bind="text:Description" /></td>
</tr>
</script>
<script>
function ViewModel(jsondata) {
var self = this;
self.fields = ko.observableArray(jsondata);
self.pageIndex = ko.observable(0);
self.pageSize = ko.observable(10);
self.pagedRows = ko.computed(function () {
var size = self.pageSize();
var start = self.pageIndex() * size;
return self.fields.slice(start, start + size);
});
self.maxPageIndex = ko.computed(function () {
return Math.ceil(self.fields().length / self.pageSize()) - 1;
});
self.next = function () {
self.pageIndex(self.pageIndex + 1);
}
self.previous = function () {
self.pageIndex(self.pageIndex - 1);
}
}
$(function () {
var data = [];
for (var i = 0; i < 100; i++) {
data.push({
FieldId: i,
Type: "Type" + i,
Name: "Name" + i,
Description: "Description" + i
})
}
ko.applyBindings(new ViewModel(data));
});
</script>
看起来非常直截了当,但我就是不明白。任何帮助将不胜感激。
谢谢
