Simulate pressing [enter] key on input text
<p>My code worked perfectly on changed the value of input automatic on page load with a delay between it. </p>

<p>But there's another problem, When I tried to simulate pressing the <code>[enter]</code> key on the input, it's no working, and it's submit the form and reload my page instead. </p>

<p>How I simulate pressing the <code>[enter]</code> key in the input without submit the form and without reload my page? I am use pure <code>javascript</code> without <code>jQuery</code></p>

<p><strong>This is my script :</strong> </p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var form   = document.querySelectorAll("._k3t69");
var input  = document.querySelectorAll("._7uiwk._qy55y");
var message = "Replacement..." ; 
var maxMsg  = 3 ;
var delay  = 2.5 * 1000 ; // 2.5 Seconds

var j = 0, k = 0;
function setValue(){
  if( j == maxMsg || j == input.length) {
   clearInterval(looping)
  } else {
  input[j++].value = message ;
    //And then simulate pressing enter key ON THE INPUT, not sumbit the form
    form[k++].submit();
  }
}

var looping = setInterval(setValue, delay);</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;form class="_k3t69"&gt;
    &lt;input type="text" class="_7uiwk _qy55y"&gt;
&lt;/form&gt;

&lt;form class="_k3t69"&gt;
    &lt;input type="text" class="_7uiwk _qy55y"&gt;
&lt;/form&gt;

&lt;form class="_k3t69"&gt;
    &lt;input type="text" class="_7uiwk _qy55y"&gt;
&lt;/form&gt;</code></pre>
</div>
