我正在使用来自Knockout.JS网站(http://jsfiddle.net/rniemeyer/QSRBR/)的分页网格示例来构建网格。我在网格模板中声明了一个click事件,如下所示(click:goBackward): -
templateEngine.addTemplate("ko_negrid_navigation", "\
<div class=\"ko-grid-pageLinks\">\
<br/>\
<span><img src=\"/OCSENET/images/bluLeftNew.gif\" style=\"cursor:hand;\" alt=\"Backward\" data-bind='click: goBackward, visible: shouldShowBack' /></span>\
<span> </span>\
<span><img src=\"/OCSENET/images/bluRightNew.gif\" style=\"cursor:hand;\" alt=\"Forward\" data-bind='click: goForward, visible: shouldShowFwd' /></span>\
</div>");
现在我需要在调用此Grid ViewModel的ViewModel中定义此goBackward方法,而不是在此Grid View模型中调用它自己。当我这样做时,事件不会触发goBackward()。我从另一个TestViewModel调用Grid,如下所示:
/*----------------------------------------------------------------------*/
/* TEST View Model
/*----------------------------------------------------------------------*/
function TESTViewModel() {
var self = this;
self.iRowFrom = ko.observable(1);
self.iRowTo = ko.observable(5);
self.gridRowCount = ko.observable(5);
self.VM_AHISGrid;
self.GridItems = ko.observableArray([]);
//fnDesignGrid
self.fnDesignGrid = function () {
self.VM_AHISGrid = new ko.NEGrid.viewModel({
data: self.GridItems,
columns: [
{ headerText: "Address", rowText: "AHIS_Address" },
{ headerText: "City", rowText: "AHIS_Addr_City" },
{ headerText: "State", rowText: "AHIS_Addr_State" },
{ headerText: "Zip", rowText: "AHIS_Addr_Zip" }
],
pageSize: self.gridRowCount(),
gridName: 'ALST_NE_GRID'
});
}
// I want this method to be triggered.
self.goBackward = function () {
alert('I m Backward')
};
}

好的,我修好了。非常简单,只需在调用viewmodel中定义方法,如下所示,它就像魅力一样。
self.NEGridViewModel.goBackward = function () {
alert('I m Backward')
};

如果您的网格是视图模型的子网,那么在您的寻呼机模板中,您需要执行类似click: $parent.goBackward
或click: $root.goBackward
的操作来绑定生活在更高范围级别的函数
