document.getElementById replacement in angular4 / typescript? : <p>So, im working with angular4 in my practice work and this is new for me.
Luckyly, in order to get html elements and its values i used 
<code>&lt;HTMLInputElement&gt; document.getElementById</code> or 
<code>&lt;HTMLSelectElement&gt; document.getElementById</code></p>

<p>Im wondering if there is any replacement for this in angular</p>
