當我有輸入和按鈕時,我有頁面。覆蓋輸入時更新值按
<div>
<div class="input-group">
<span class="input-group-addon">Enter test</span>
<input type="Text" class="form-control" data-bind="value:Test, event: { keypress: searchKeyboardCmd}" required />
</div>
</div>
<button data-bind=' event:{click:foo}' class="btn btn-default">Submit</button>
和我的代碼:
var ViewModel = function() {
var self = this;
self.Test = ko.observable();
self.data = ko.observableArray([]);
self.DeviceId = ko.observable();
self.number = ko.observable(1);
self.MeUser = ko.observable(true);
self.searchKeyboardCmd = function (data, event) {
if (event.keyCode == 13)
alert("Znalazlem enter " + ko.toJSON(self));
return true;
};
self.foo = function() {
alert("foo");
}
};
ko.applyBindings(new ViewModel());
});
我的代碼有問題。我用這個代碼捕獲輸入:
self.searchKeyboardCmd = function (data, event) {
if (event.keyCode == 13)
alert("Znalazlem enter " + ko.toJSON(self));
return true;
};
它完美地捕獲,但綁定的對象在調用alert後更新。所以在第一次輸入值爲Test時爲null。第二次輸入後,我有第一個值,等等。任何人都可以建議我如何修改此代碼?
