angular2 TypeError: self._el_11 is not a function

Question

我想为输入添加事件侦听器，这是我的代码

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

搜索方法是

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

然后当我输入一些东西时，浏览器控制台日志是

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代码是

_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);};

Answer 1

那是因为您定义了与您的方法同名的模板引用变量。

因此将其更改为：

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