Angular2 encountered a TypeError stating that self._el_11 is not a valid function

Looking to attach an event listener to an input field? Check out the code snippet below:

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

Here is the corresponding search method:

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

When entering text, you might encounter this error message in the browser console:

TypeError: self._el_11 is not a function
at AppView._View_YwCoffeeListComponent0._handle_click_11_0 (YwCoffeeListComponent.ngfactory.js:217)
at platform-browser.umd.js:1854
at platform-browser.umd.js:1967
at ZoneDelegate.invoke (zone.js:192)

at NgZone.runGuarded (core.umd.js:9038)
at HTMLInputElement.i (platform-browser.umd.js:1967)

The code at YwCoffeeListComponent.ngfactory.js:217 looks like this:

_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

The reason for this issue is that you have used the same name for your template reference variable as your method.

To resolve this, update it to:

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