I'm trying to generate a text-box after a button click event. The code is as follows. 

<div id="welcomeDiv"  class="answer_list" > WELCOME </div>
<input type="button" name="answer" value="Show Div" onclick="showDiv()" />
</div>
<?php if(isset($_POST['button'])) { ?>
<?php echo "<script type=\"text/javascript\">
   function showDiv() {

   <input type="text" id="textInput" value="..." />
   document.getElementById('welcomeDiv').style.display = "block"; </script> ";
   }
   </script>" ?> ;
<?php } ?>

But the button click event function is not working properly. Any thoughts?

You can also create css and make visible textfield on button click

Hope below example will help you

function onButtonClick(){
  document.getElementById('textInput').className="show";
}
.hide{
  display:none;
}
.show{
  display:block;
}
<div class="answer_list" > WELCOME </div>
<input type="button" name="answer" value="Show Text Field" onclick="onButtonClick()" />
<input class="hide" type="text" id="textInput" value="..." />

Using JQuery you can do it like, here's a FIDDLE

<div id="welcomeDiv" class="answer_list"> WELCOME </div>
<br>
<input type="button" id="myButton" name="answer" value="Show Div" />
<br>
<br>
<input type="text" id="textInput" value="" hidden/>

$(document).ready(function() {
  $("#myButton").click(function() {
    $("#textInput").show();
  });
});

Using Plain JavaScript, here's a FIDDLE

<div id="welcomeDiv" class="answer_list"> WELCOME </div>
<br>
<input type="button" id="myButton" name="answer" value="Show Div" onclick="showInputBox()" />
<br>
<br>
<input type="text" id="textInput" value="" hidden/>

<script>
  function showInputBox() {
    if (document.getElementById("textInput")) {
      document.getElementById("textInput").style.display = 'block';
      alert("Yes");
    } else {
      //IF INPUT BOX DOES NOT EXIST
      var inputBox = document.createElement("INPUT");
      inputBox.setAttribute("type", "text");
      inputBox.setAttribute("id", "dynamicTextInput");
      document.body.appendChild(inputBox);
      alert("No");
    }
  }
</script>

You don't need use PHP! Is better to use Jquery for this action.

$(document).ready(function() {
  $("#myButton").click(function() {
    $("#myButton").after('<input type="text" id="textInput" value="">');
  });
});
input{
  display:block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="welcomeDiv" class="answer_list"> WELCOME </div>
<br>
<input type="button" id="myButton" name="answer" value="Show Div" />

Hi Ryan please check this code it will create a text box and add it before button.

 <div id="welcomeDiv"  class="answer_list" > WELCOME </div>
 <div id="tbox_div">
 </div>
 <input type="button" name="answer" value="Show Div" onclick="showDiv()" />
 <script>
 function showDiv(){
var newtextbox ='';
if (!document.getElementById("textInput")) {
 newtextbox += '<input type="text" id="textInput" value="..." />'; 
    document.getElementById('tbox_div').innerHTML+=newtextbox;
  }
  }

if you want to add more that one text boxes then remove this if condition.

if (!document.getElementById("textInput"))
