angular2類型錯誤：self._el_11不是一個函數

Question

我想事件偵聽器添加到輸入，這裏是我的代碼

<input ref-search (keyup)="search(search.value)"> 

和搜索方法是

search(condition: string){ 
    console.log(condition); 
} 

然後當我輸入的東西，瀏覽器控制檯日誌

TypeError: self._el_11 is not a function 
at AppView._View_YwCoffeeListComponent0._handle_click_11_0 (YwCoffeeListComponent.ngfactory.js:217)

和YwCoffeeListComponent.ngfactory.js：217碼

_View_YwCoffeeListComponent0.prototype._handle_click_11_0 = function($event) {var self = this;self.markPathToRootAsCheckOnce();var pd_0 = (self._el_11(self._el_11.value) !== false);return (true && pd_0);};

這是因爲您定義了模板引用變量，其名稱與您的方法相同。

因此，與改變：

<input ref-searchInput (keyup)="search(searchInput.value)">
