【问题描述】:
我需要通过键盘控制行为页面......我正在尝试这样:
this.showSearcherCustomerKeyCommand = function (data, event) {
if (event.shiftKey && event.keyCode == 49) {
alert("Combination done !");
}
};
我在一个部分中设置了绑定,在我在一个div中设置了绑定之后,结果不成功......所以我需要的是我的页面的行为可以通过键盘控制......我的用户可以进行这种组合:Crtl + 1,ctrl + 2,通过淘汰赛我可以显示,隐藏(模态),应用或清理节点绑定以及其他东西......这可能吗?谢谢...
更新
这是我的视图模型:
Billing.BillingViewModel = function () {
this.billingDate = ko.observable();
this.billingCode = ko.observable();
this.billingId = ko.observable();
this.billingIva = ko.observable(0);
this.billingSubTotal = ko.observable(0);
this.billingTotal = ko.observable(0);
this.billingObservations = ko.observable("");
this.billingDetails = ko.observableArray();
this.billingState = ko.observable();
this.billingClient = new Billing.ClientViewModel();
this.billingCurrentProductSelected = new Billing.ProductViewModel();
this.showSearcherCustomerKeyCommand = function (data, event) {
if (event.shiftKey && event.keyCode == 49) {
alert("Combination done !");
}
};
};
这是应用绑定的时间:
Billing.SetViewModel = function () {
theMainViewModel = Billing.PrepareBilling();
theManagerViewModel = new Billing.ManagerBillingViewModel();
theGeneralViewModel = new Billing.GeneralViewModel();
ko.applyBindings(theMainViewModel.Billing, $("#" + Billing.BillingHeaderSecction)[0]);
ko.applyBindings(theMainViewModel.Billing, $("#" + Billing.BillFooterSecction)[0]);
ko.applyBindings(theMainViewModel.Billing, $("#" + Billing.BillProductChoosenSecction)[0]);
ko.applyBindings(theMainViewModel.Billing, $("#" + Billing.BillDetailsSecction)[0]);
ko.applyBindings(theMainViewModel.FinishBilling, $("#" + Billing.BillFinishSecction)[0]);
ko.applyBindings(theManagerViewModel, $("#" + Billing.ManagerSecction)[0]);
ko.applyBindings(theMainViewModel, $("#" + Billing.BillActionsSecction)[0]);
ko.applyBindings(theMainViewModel, $("#" + Billing.SelectorModalSearcherCustomerId)[0]);
ko.applyBindings(theMainViewModel, $("#" + Billing.SelectorModalSearcherProductId)[0]);
//ko.applyBindings(theGeneralViewModel, $("#" + Billing.BillGeneralSecction)[0]);
theManagerViewModel.theBillings.push(theMainViewModel);
Billing.SetMask();
};
这是我的部分标签控件(HTML):
<section id="BillHeaderSecction" **data-bind="event: { keypress: billingClient.showSearcherCustomerKeyCommand }, valueupdate: 'afterkeydown'"**>
<input type="hidden" id="hdfBillingId" name="BillingId" data-bind="value: billingId" />
<table style="width: 100%">
<tr>
<td style="width: 30%">
<label>Cliente</label>
<input style="width: 100%" type="text" readonly name="Client" id="txtClient" data-bind="value: billingClient.name" />
</td>
<td style="width: 5%"></td>
<td style="width: 30%">
<label>Fecha</label>
<input style="width: 100%" type="text" readonly name="CreationDate" id="txtCreationDate" data-bind="value: billingDate" />
</td>
<td style="width: 5%"></td>
<td style="width: 30%">
<label>Código</label>
<input style="width: 100%" type="text" readonly name="BillingCode" id="txtBillingCode" data-bind="value: billingCode" />
</td>
</tr>
</table>
</section>
PD:我已经将我希望被键盘控制的部分标记加粗
【问题讨论】:
-
是的,这是可能的。显示其余代码。事件监听器在哪里?
