I am trying to make a table appear when I click on a submit button in a form.
I am using JavaScript for that function.
See code below:



<script type="text/javascript">
function showTable1234() {
var showtab = document.getElementsByClassName('container12');
for(var i =0;i !=showtab.length;i++)
showtab[i].style.display = 'block';
}
</script>


Here is the code for the button which is calling the above function:



<button type="submit" class="btn btn-primary btn-block" onclick="showTable1234()">Submit</button>


This is div element which is to be shown on clicking the submit button:



<div class="container12" >
<h2>Hover Rows</h2>
<table class="table table-hover" id = "tab12">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
.....


Now as soon as I run the code on the Chrome browser and clicking on submit button, table is visible only but only for mini second or something and the disappears.
It appears again when i click on submit button but again for same amount of time.



I even tried with this code but same result



<script type="text/javascript">
function showTable1234() {
var showtab = document.getElementsByClassName('container12')[0];
for(var i =0;i !=showtab.length;i++)
showtab[i].style.display = 'block';
}
</script>


But for this i am getting this error



Uncaught TypeError: Cannot read property 'style' of undefined
at showTable1234


Advance Thanks for the help.

    One error is that you submit the page so you will never see the result - change the button to a button <button type="button" class="btn btn-primary btn-block" onclick="showTable1234()">Submit</button> or use AJAX

To stop the form submit, you can add onSubmit=“return false” to the form. You can also stop the submit by returning false from your button’s onClick, or use a button of type button rather than submit.

Add a return false at the end of the function and return the returned value of showTable1234 in the click handler of the button to prevent the default action (which is submitting the form and thus refreshing the page).
