    document.getElementById("theForm").style.display="block";
}

html :

<button id="search" onclick="show()">show</button>
</form>
<form class="form-horizontal" action="FormController/save" method = "POST" id="theForm" style="display: none">

Answer 1

Default behavior of button is submit , hence the form is submitted. You can use type="button" which doesn't have default behavior, thus it can be associated with client-side event handlers.

<button type="button" id="search" onclick="show()">show</button>

---

Additionally, I would recommend you do get rid of of ugly inline click handlers and bind event handler using addEventListener()

 document.querySelector('#search').addEventListener("click", show, false);

HTML

<button type="button" id="search">show</button>

Answer 2

If you're using jQuery as your tags says so you could do it like :

$('#seach').on('click', function(){
    $('#theForm').show();
})

Hope this helps.

 $('#search').on('click', function(){ $('#theForm').show(); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <button id="search">Show</button> <br> <form class="form-horizontal" action="FormController/save" method = "POST" id="theForm" style="display: none"> MY FORM </form>

Try This:

Java Script:

            function show(){
            document.getElementById("theForm").style.display="block";
        }
html :

<input type="button" onclick="show()" id="search" value="show">
            </form>
            <form class="form-horizontal" action="FormController/save" method = "POST" id="theForm" style="display: none">

<script>
 $(document).ready(function(){   
     $("#what").click(function() { //call event
         $(".hello").hide();//hide forms
         $('neededFormOnly').show();  //show only the needed form
         return false 
   });
 });
</script>
