get input value and change div

Question

I am trying to change the span with the input value what is the error on my code.

$(document).ready(function(){
  if ($('#tnx-status').val() = 'publish'){
    $("#status-p").html("Complited")
  }
   });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="tnxst" type="hidden" id="tnx-status" value="publish" />
<span id="status-p"></span>

Look at your browser's debugging console. It's telling you exactly what the problem is. Or even just click "Run code snippet" in your own question. — David, Sep 16 '17 at 20:27
When you were trying, what was the error message? What line of code did it refer to? What is the error message telling you and how are you trying to apply that information to your code? — David, Sep 16 '17 at 20:30
"ReferenceError: invalid assignment left-hand side", "lineno": 16, "colno": 7 but as a new on jquery I can't understand this . — Utpal Sarkar, Sep 16 '17 at 20:32
The problem is that you have a typo in your code. You're using `=` instead of `==` (or `===`). — David, Sep 16 '17 at 20:34

use comparison operator === instead of assignment operator =

$(document).ready(function(){
  if ($('#tnx-status').val() === 'publish'){
    $("#status-p").html("Complited")
  }
   });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="tnxst" type="hidden" id="tnx-status" value="publish" />
<span id="status-p"></span>
