[英]knockout js: data-bind click not working
我無法通過簡單的按鈕單擊來在我的網站上觸發logMyStuff
淘汰賽功能。 注意,我添加了<button>
, <a>
和<div>
來嘗試使其工作。 我做了一個JS提琴,但JS提琴奏效了。
這是我的代碼:
var SearchFilterViewModel = (function () {
function SearchFilterViewModel() {
this.logMyStuff = function () {
console.log("stuff");
};
this._categoryID = 1;
this._categories = ko.observableArray([
new Category("Vegan Meat", 1),
new Category("Vegan Dairy", 2),
new Category("Confectionary", 3),
new Category("Baking", 4),
new Category("Restaurants", 5),
new Category("Fashion", 6)
]);
this._regionGetter = new AreaGetter();
this._townGetter = new AreaGetter();
this._regionGetter.getAreas("2186224");
this._regionGetter._selectedArea.subscribe(this._townGetter.getAreas.bind(this._townGetter));
}
return SearchFilterViewModel;
})();
$(document).ready(function () {
var _searchFilterViewModel = new SearchFilterViewModel();
var _searchFilterForm = $("#find-vegan-products-page").find("form")[0];
ko.applyBindings(_searchFilterViewModel, _searchFilterForm);
});
HTML:
<div id="find-vegan-products-page" class="full-size container-fluid" style="height:900px; padding: 70px 40px 40px 40px;">
<!-- TODO: Make blackand white video section a bit shorter -->
<h1 style="margin:0px 0px 20px 0px; color: dimgray;">FILTER YOUR SEARCH</h1>
<button style="width:100px;height:100px;" data-bind="click: logMyStuff"></button>
<a style="width:100px;height:100px;" data-bind="click: logMyStuff"></a>
<div style="width:100px;height:100px;" data-bind="click: logMyStuff"></div>
<form role="form">
<div class="row">
<?
echo RegionSelect::display();
echo TownSelect::display();
//echo CategorySelect::display();
?>
</div>
<div class="row">
<div class="col-sm-12">
<div id="go-button"
class="with-border clickable"
href="#find-vegan-products-page" >
<h5 class=" text-center medium-text">GO</h5>
</div>
</div>
</div>
</form>
</div>
這是因為您在applyBinding()
定義的applyBinding()
是<form>
,而調用logMyStuff()
的<button>
, <a>
和<div>
不在該表單之外。
嘗試以下方法:
var _searchFilterRoot = $("#find-vegan-products-page")[0];
ko.applyBindings(_searchFilterViewModel, _searchFilterRoot);
